+# Crawl4AI Prospect‑Wizard – step‑by‑step guide
+
+A three‑stage demo that goes from **LinkedIn scraping** ➜ **LLM reasoning** ➜ **graph visualisation**.
+
+```
+prospect‑wizard/
+├─ c4ai_discover.py         # Stage 1 – scrape companies + people
+├─ c4ai_insights.py         # Stage 2 – embeddings, org‑charts, scores
+├─ graph_view_template.html # Stage 3 – graph viewer (static HTML)
+└─ data/                    # output lands here (*.jsonl / *.json)
+```
+
+---
+
+## 1  Install & boot a LinkedIn profile (one‑time)
+
+### 1.1  Install dependencies
+```bash
+pip install crawl4ai openai sentence-transformers networkx pandas vis-network rich
+```
+
+### 1.2  Create / warm a LinkedIn browser profile
+```bash
+crwl profiler
+```
+1. The interactive shell shows **New profile** – hit **enter**.
+2. Choose a name, e.g. `profile_linkedin_uc`.
+3. A Chromium window opens – log in to LinkedIn, solve whatever CAPTCHA, then close.
+
+> Remember the **profile name**. All future runs take `--profile-name <your_name>`.
+
+---
+
+## 2  Discovery – scrape companies & people
+
+```bash
+python c4ai_discover.py full \ 
+  --query "health insurance management" \ 
+  --geo 102713980 \               # Malaysia geoUrn
+  --title_filters "" \            # or "Product,Engineering"
+  --max_companies 10 \            # default set small for workshops
+  --max_people 20 \               # \^ same
+  --profile-name profile_linkedin_uc \ 
+  --outdir ./data \ 
+  --concurrency 2 \ 
+  --log_level debug
+```
+**Outputs** in `./data/`:
+* `companies.jsonl` – one JSON per company
+* `people.jsonl` – one JSON per employee
+
+🛠️  **Dry‑run:** `C4AI_DEMO_DEBUG=1 python c4ai_discover.py full --query coffee` uses bundled HTML snippets, no network.
+
+### Handy geoUrn cheatsheet
+| Location | geoUrn |
+|----------|--------|
+| Singapore | **103644278** |
+| Malaysia | **102713980** |
+| United States | **103644922** |
+| United Kingdom | **102221843** |
+| Australia | **101452733** |
+_See more: <https://www.linkedin.com/search/results/companies/?geoUrn=XXX> – the number after `geoUrn=` is what you need._
+
+---
+
+## 3  Insights – embeddings, org‑charts, decision makers
+
+```bash
+python c4ai_insights.py \ 
+  --in  ./data \ 
+  --out ./data \ 
+  --embed_model all-MiniLM-L6-v2 \ 
+  --top_k 10 \ 
+  --openai_model gpt-4.1 \ 
+  --max_llm_tokens 8024 \ 
+  --llm_temperature 1.0 \ 
+  --workers 4
+```
+Emits next to the Stage‑1 files:
+* `company_graph.json` – inter‑company similarity graph
+* `org_chart_<handle>.json` – one per company
+* `decision_makers.csv` – hand‑picked ‘who to pitch’ list
+
+Flags reference (straight from `build_arg_parser()`):
+| Flag | Default | Purpose |
+|------|---------|---------|
+| `--in` | `.` | Stage‑1 output dir |
+| `--out` | `.` | Destination dir |
+| `--embed_model` | `all-MiniLM-L6-v2` | Sentence‑Transformer model |
+| `--top_k` | `10` | Neighbours per company in graph |
+| `--openai_model` | `gpt-4.1` | LLM for scoring decision makers |
+| `--max_llm_tokens` | `8024` | Token budget per LLM call |
+| `--llm_temperature` | `1.0` | Creativity knob |
+| `--stub` | off | Skip OpenAI and fabricate tiny charts |
+| `--workers` | `4` | Parallel LLM workers |
+
+---
+
+## 4  Visualise – interactive graph
+
+After Stage 2 completes, simply open the HTML viewer from the project root:
+```bash
+open graph_view_template.html   # or Live Server / Python -http
+```
+The page fetches `data/company_graph.json` and the `org_chart_*.json` files automatically; keep the `data/` folder beside the HTML file.
+
+* Left pane → list of companies (clans).
+* Click a node to load its org‑chart on the right.
+* Chat drawer lets you ask follow‑up questions; context is pulled from `people.jsonl`.
+
+---
+
+## 5  Common snags
+
+| Symptom | Fix |
+|---------|-----|
+| Infinite CAPTCHA | Use a residential proxy: `--proxy http://user:pass@ip:port` |
+| 429 Too Many Requests | Lower `--concurrency`, rotate profile, add delay |
+| Blank graph | Check JSON paths, clear `localStorage` in browser |
+
+---
+
+### TL;DR
+`crwl profiler` → `c4ai_discover.py` → `c4ai_insights.py` → open `graph_view_template.html`.  
+Live long and `import crawl4ai`.

+c4ai-discover — Stage‑1 Discovery CLI
+
+Scrapes LinkedIn company search + their people pages and dumps two newline‑delimited
+JSON files: companies.jsonl and people.jsonl.
+
+Key design rules
+----------------
+* No BeautifulSoup — Crawl4AI only for network + HTML fetch.
+* JsonCssExtractionStrategy for structured scraping; schema auto‑generated once
+  from sample HTML provided by user and then cached under ./schemas/.
+* Defaults are embedded so the file runs inside VS Code debugger without CLI args.
+* If executed as a console script (argv > 1), CLI flags win.
+* Lightweight deps: argparse + Crawl4AI stack.

+### browser_manager.py
+
+| Function | What it does |
+|---|---|
+| `ManagedBrowser.build_browser_flags` | Returns baseline Chromium CLI flags, disables GPU and sandbox, plugs locale, timezone, stealth tweaks, and any extras from `BrowserConfig`. |
+| `ManagedBrowser.__init__` | Stores config and logger, creates temp dir, preps internal state. |
+| `ManagedBrowser.start` | Spawns or connects to the Chromium process, returns its CDP endpoint plus the `subprocess.Popen` handle. |
+| `ManagedBrowser._initial_startup_check` | Pings the CDP endpoint once to be sure the browser is alive, raises if not. |
+| `ManagedBrowser._monitor_browser_process` | Async-loops on the subprocess, logs exits or crashes, restarts if policy allows. |
+| `ManagedBrowser._get_browser_path_WIP` | Old helper that maps OS + browser type to an executable path. |
+| `ManagedBrowser._get_browser_path` | Current helper, checks env vars, Playwright cache, and OS defaults for the real executable. |
+| `ManagedBrowser._get_browser_args` | Builds the final CLI arg list by merging user flags, stealth flags, and defaults. |
+| `ManagedBrowser.cleanup` | Terminates the browser, stops monitors, deletes the temp dir. |
+| `ManagedBrowser.create_profile` | Opens a visible browser so a human can log in, then zips the resulting user-data-dir to `~/.crawl4ai/profiles/<name>`. |
+| `ManagedBrowser.list_profiles` | Thin wrapper, now forwarded to `BrowserProfiler.list_profiles()`. |
+| `ManagedBrowser.delete_profile` | Thin wrapper, now forwarded to `BrowserProfiler.delete_profile()`. |
+| `BrowserManager.__init__` | Holds the global Playwright instance, browser handle, config signature cache, session map, and logger. |
+| `BrowserManager.start` | Boots the underlying `ManagedBrowser`, then spins up the default Playwright browser context with stealth patches. |
+| `BrowserManager._build_browser_args` | Translates `CrawlerRunConfig` (proxy, UA, timezone, headless flag, etc.) into Playwright `launch_args`. |
+| `BrowserManager.setup_context` | Applies locale, geolocation, permissions, cookies, and UA overrides on a fresh context. |
+| `BrowserManager.create_browser_context` | Internal helper that actually calls `browser.new_context(**options)` after running `setup_context`. |
+| `BrowserManager._make_config_signature` | Hashes the non-ephemeral parts of `CrawlerRunConfig` so contexts can be reused safely. |
+| `BrowserManager.get_page` | Returns a ready `Page` for a given session id, reusing an existing one or creating a new context/page, injects helper scripts, updates `last_used`. |
+| `BrowserManager.kill_session` | Force-closes a context/page for a session and removes it from the session map. |
+| `BrowserManager._cleanup_expired_sessions` | Periodic sweep that drops sessions idle longer than `ttl_seconds`. |
+| `BrowserManager.close` | Gracefully shuts down all contexts, the browser, Playwright, and background tasks. |
+
+---
+
+### browser_profiler.py
+
+| Function | What it does |
+|---|---|
+| `BrowserProfiler.__init__` | Sets up profile folder paths, async logger, and signal handlers. |
+| `BrowserProfiler.create_profile` | Launches a visible browser with a new user-data-dir for manual login, on exit compresses and stores it as a named profile. |
+| `BrowserProfiler.cleanup_handler` | General SIGTERM/SIGINT cleanup wrapper that kills child processes. |
+| `BrowserProfiler.sigint_handler` | Handles Ctrl-C during an interactive session, makes sure the browser shuts down cleanly. |
+| `BrowserProfiler.listen_for_quit_command` | Async REPL that exits when the user types `q`. |
+| `BrowserProfiler.list_profiles` | Enumerates `~/.crawl4ai/profiles`, prints profile name, browser type, size, and last modified. |
+| `BrowserProfiler.get_profile_path` | Returns the absolute path of a profile given its name, or `None` if missing. |
+| `BrowserProfiler.delete_profile` | Removes a profile folder or a direct path from disk, with optional confirmation prompt. |
+| `BrowserProfiler.interactive_manager` | Text UI loop for listing, creating, deleting, or launching profiles. |
+| `BrowserProfiler.launch_standalone_browser` | Starts a non-headless Chromium with remote debugging enabled and keeps it alive for manual tests. |
+| `BrowserProfiler.get_cdp_json` | Pulls `/json/version` from a CDP endpoint and returns the parsed JSON. |
+| `BrowserProfiler.launch_builtin_browser` | Spawns a headless Chromium in the background, saves `{wsEndpoint, pid, started_at}` to `~/.crawl4ai/builtin_browser.json`. |
+| `BrowserProfiler.get_builtin_browser_info` | Reads that JSON file, verifies the PID, and returns browser status info. |
+| `BrowserProfiler._is_browser_running` | Cross-platform helper that checks if a PID is still alive. |
+| `BrowserProfiler.kill_builtin_browser` | Terminates the background builtin browser and removes its status file. |
+| `BrowserProfiler.get_builtin_browser_status` | Returns `{running: bool, wsEndpoint, pid, started_at}` for quick health checks. |

+### `cli.py` command surface
+
+| Command | Inputs / flags | What it does |
+|---|---|---|
+| **profiles** | *(none)* | Opens the interactive profile manager, lets you list, create, delete saved browser profiles that live in `~/.crawl4ai/profiles`. |
+| **browser status** | – | Prints whether the always-on *builtin* browser is running, shows its CDP URL, PID, start time. |
+| **browser stop** | – | Kills the builtin browser and deletes its status file. |
+| **browser view** | `--url, -u` URL *(optional)* | Pops a visible window of the builtin browser, navigates to `URL` or `about:blank`. |
+| **config list** | – | Dumps every global setting, showing current value, default, and description. |
+| **config get** | `key` | Prints the value of a single setting, falls back to default if unset. |
+| **config set** | `key value` | Persists a new value in the global config (stored under `~/.crawl4ai/config.yml`). |
+| **examples** | – | Just spits out real-world CLI usage samples. |
+| **crawl** | `url` *(positional)*<br>`--browser-config,-B` path<br>`--crawler-config,-C` path<br>`--filter-config,-f` path<br>`--extraction-config,-e` path<br>`--json-extract,-j` [desc]\*<br>`--schema,-s` path<br>`--browser,-b` k=v list<br>`--crawler,-c` k=v list<br>`--output,-o` all,json,markdown,md,markdown-fit,md-fit *(default all)*<br>`--output-file,-O` path<br>`--bypass-cache,-b` *(flag, default true — note flag reuse)*<br>`--question,-q` str<br>`--verbose,-v` *(flag)*<br>`--profile,-p` profile-name | One-shot crawl + extraction. Builds `BrowserConfig` and `CrawlerRunConfig` from inline flags or separate YAML/JSON files, runs `AsyncWebCrawler.run()`, can route through a named saved profile and pipe the result to stdout or a file. |
+| **(default)** | Same flags as **crawl**, plus `--example` | Shortcut so you can type just `crwl https://site.com`. When first arg is not a known sub-command, it falls through to *crawl*. |
+
+\* `--json-extract/-j` with no value turns on LLM-based JSON extraction using an auto schema, supplying a string lets you prompt-engineer the field descriptions.
+
+> Quick mental model  
+> `profiles` = manage identities,  
+> `browser ...` = control long-running headless Chrome that all crawls can piggy-back on,  
+> `crawl` = do the actual work,  
+> `config` = tweak global defaults,  
+> everything else is sugar.
+
+### Quick-fire “profile” usage cheatsheet
+
+| Scenario | Command (copy-paste ready) | Notes |
+|---|---|---|
+| **Launch interactive Profile Manager UI** | `crwl profiles` | Opens TUI with options: 1 List, 2 Create, 3 Delete, 4 Use-to-crawl, 5 Exit. |
+| **Create a fresh profile** | `crwl profiles` → choose **2** → name it → browser opens → log in → press **q** in terminal | Saves to `~/.crawl4ai/profiles/<name>`. |
+| **List saved profiles** | `crwl profiles` → choose **1** | Shows name, browser type, size, last-modified. |
+| **Delete a profile** | `crwl profiles` → choose **3** → pick the profile index → confirm | Removes the folder. |
+| **Crawl with a profile (default alias)** | `crwl https://site.com/dashboard -p my-profile` | Keeps login cookies, sets `use_managed_browser=true` under the hood. |
+| **Crawl + verbose JSON output** | `crwl https://site.com -p my-profile -o json -v` | Any other `crawl` flags work the same. |
+| **Crawl with extra browser tweaks** | `crwl https://site.com -p my-profile -b "headless=true,viewport_width=1680"` | CLI overrides go on top of the profile. |
+| **Same but via explicit sub-command** | `crwl crawl https://site.com -p my-profile` | Identical to default alias. |
+| **Use profile from inside Profile Manager** | `crwl profiles` → choose **4** → pick profile → enter URL → follow prompts | Handy when demo-ing to non-CLI folks. |
+| **One-off crawl with a profile folder path (no name lookup)** | `crwl https://site.com -b "user_data_dir=$HOME/.crawl4ai/profiles/my-profile,use_managed_browser=true"` | Bypasses registry, useful for CI scripts. |
+| **Launch a dev browser on CDP port with the same identity** | `crwl cdp -d $HOME/.crawl4ai/profiles/my-profile -P 9223` | Lets Puppeteer/Playwright attach for debugging. |

-## 4. Why “No LLM” Is Often Better
+## 4. RegexExtractionStrategy - Fast Pattern-Based Extraction
 
-1. **Zero Hallucination**: Schema-based extraction doesn’t guess text. It either finds it or not.  
+Crawl4AI now offers a powerful new zero-LLM extraction strategy: `RegexExtractionStrategy`. This strategy provides lightning-fast extraction of common data types like emails, phone numbers, URLs, dates, and more using pre-compiled regular expressions.
-2. **Guaranteed Structure**: The same schema yields consistent JSON across many pages, so your downstream pipeline can rely on stable keys.  
-3. **Speed**: LLM-based extraction can be 10–1000x slower for large-scale crawling.  
-4. **Scalable**: Adding or updating a field is a matter of adjusting the schema, not re-tuning a model.
 
-**When might you consider an LLM?** Possibly if the site is extremely unstructured or you want AI summarization. But always try a schema approach first for repeated or consistent data patterns.
+### Key Features
+
+- **Zero LLM Dependency**: Extracts data without any AI model calls
+- **Blazing Fast**: Uses pre-compiled regex patterns for maximum performance
+- **Built-in Patterns**: Includes ready-to-use patterns for common data types
+- **Custom Patterns**: Add your own regex patterns for domain-specific extraction
+- **LLM-Assisted Pattern Generation**: Optionally use an LLM once to generate optimized patterns, then reuse them without further LLM calls
+
+### Simple Example: Extracting Common Entities
+
+The easiest way to start is by using the built-in pattern catalog:
+
+```python
+import json
+import asyncio
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig,
+    RegexExtractionStrategy
+)
+
+async def extract_with_regex():
+    # Create a strategy using built-in patterns for URLs and currencies
+    strategy = RegexExtractionStrategy(
+        pattern = RegexExtractionStrategy.Url | RegexExtractionStrategy.Currency
+    )
+    
+    config = CrawlerRunConfig(extraction_strategy=strategy)
+    
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            url="https://example.com",
+            config=config
+        )
+        
+        if result.success:
+            data = json.loads(result.extracted_content)
+            for item in data[:5]:  # Show first 5 matches
+                print(f"{item['label']}: {item['value']}")
+            print(f"Total matches: {len(data)}")
+
+asyncio.run(extract_with_regex())
+```
+
+### Available Built-in Patterns
+
+`RegexExtractionStrategy` provides these common patterns as IntFlag attributes for easy combining:
+
+```python
+# Use individual patterns
+strategy = RegexExtractionStrategy(pattern=RegexExtractionStrategy.Email)
+
+# Combine multiple patterns
+strategy = RegexExtractionStrategy(
+    pattern = (
+        RegexExtractionStrategy.Email | 
+        RegexExtractionStrategy.PhoneUS | 
+        RegexExtractionStrategy.Url
+    )
+)
+
+# Use all available patterns
+strategy = RegexExtractionStrategy(pattern=RegexExtractionStrategy.All)
+```
+
+Available patterns include:
+- `Email` - Email addresses
+- `PhoneIntl` - International phone numbers
+- `PhoneUS` - US-format phone numbers
+- `Url` - HTTP/HTTPS URLs
+- `IPv4` - IPv4 addresses
+- `IPv6` - IPv6 addresses
+- `Uuid` - UUIDs
+- `Currency` - Currency values (USD, EUR, etc.)
+- `Percentage` - Percentage values
+- `Number` - Numeric values
+- `DateIso` - ISO format dates
+- `DateUS` - US format dates
+- `Time24h` - 24-hour format times
+- `PostalUS` - US postal codes
+- `PostalUK` - UK postal codes
+- `HexColor` - HTML hex color codes
+- `TwitterHandle` - Twitter handles
+- `Hashtag` - Hashtags
+- `MacAddr` - MAC addresses
+- `Iban` - International bank account numbers
+- `CreditCard` - Credit card numbers
+
+### Custom Pattern Example
+
+For more targeted extraction, you can provide custom patterns:
+
+```python
+import json
+import asyncio
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig,
+    RegexExtractionStrategy
+)
+
+async def extract_prices():
+    # Define a custom pattern for US Dollar prices
+    price_pattern = {"usd_price": r"\$\s?\d{1,3}(?:,\d{3})*(?:\.\d{2})?"}
+    
+    # Create strategy with custom pattern
+    strategy = RegexExtractionStrategy(custom=price_pattern)
+    config = CrawlerRunConfig(extraction_strategy=strategy)
+    
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            url="https://www.example.com/products",
+            config=config
+        )
+        
+        if result.success:
+            data = json.loads(result.extracted_content)
+            for item in data:
+                print(f"Found price: {item['value']}")
+
+asyncio.run(extract_prices())
+```
+
+### LLM-Assisted Pattern Generation
+
+For complex or site-specific patterns, you can use an LLM once to generate an optimized pattern, then save and reuse it without further LLM calls:
+
+```python
+import json
+import asyncio
+from pathlib import Path
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig,
+    RegexExtractionStrategy,
+    LLMConfig
+)
+
+async def extract_with_generated_pattern():
+    cache_dir = Path("./pattern_cache")
+    cache_dir.mkdir(exist_ok=True)
+    pattern_file = cache_dir / "price_pattern.json"
+    
+    # 1. Generate or load pattern
+    if pattern_file.exists():
+        pattern = json.load(pattern_file.open())
+        print(f"Using cached pattern: {pattern}")
+    else:
+        print("Generating pattern via LLM...")
+        
+        # Configure LLM
+        llm_config = LLMConfig(
+            provider="openai/gpt-4o-mini",
+            api_token="env:OPENAI_API_KEY",
+        )
+        
+        # Get sample HTML for context
+        async with AsyncWebCrawler() as crawler:
+            result = await crawler.arun("https://example.com/products")
+            html = result.fit_html
+        
+        # Generate pattern (one-time LLM usage)
+        pattern = RegexExtractionStrategy.generate_pattern(
+            label="price",
+            html=html,
+            query="Product prices in USD format",
+            llm_config=llm_config,
+        )
+        
+        # Cache pattern for future use
+        json.dump(pattern, pattern_file.open("w"), indent=2)
+    
+    # 2. Use pattern for extraction (no LLM calls)
+    strategy = RegexExtractionStrategy(custom=pattern)
+    config = CrawlerRunConfig(extraction_strategy=strategy)
+    
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            url="https://example.com/products",
+            config=config
+        )
+        
+        if result.success:
+            data = json.loads(result.extracted_content)
+            for item in data[:10]:
+                print(f"Extracted: {item['value']}")
+            print(f"Total matches: {len(data)}")
+
+asyncio.run(extract_with_generated_pattern())
+```
+
+This pattern allows you to:
+1. Use an LLM once to generate a highly optimized regex for your specific site
+2. Save the pattern to disk for reuse 
+3. Extract data using only regex (no further LLM calls) in production
+
+### Extraction Results Format
+
+The `RegexExtractionStrategy` returns results in a consistent format:
+
+```json
+[
+  {
+    "url": "https://example.com",
+    "label": "email",
+    "value": "contact@example.com",
+    "span": [145, 163]
+  },
+  {
+    "url": "https://example.com",
+    "label": "url",
+    "value": "https://support.example.com",
+    "span": [210, 235]
+  }
+]
+```
+
+Each match includes:
+- `url`: The source URL
+- `label`: The pattern name that matched (e.g., "email", "phone_us")
+- `value`: The extracted text
+- `span`: The start and end positions in the source content
