# AI Chrome extension for ReadTheDocs, Docusaurus, Mintlify, and Swagger docs.

Highlight SDK reference tables, OpenAPI/Swagger specs, and configuration guides on ReadTheDocs, Docusaurus, or Mintlify and generate working code in place.

> **Best fit:** Best for developers who want one consistent, customizable keyboard shortcut (default: Ctrl+Shift+X) and custom prompt presets across every documentation framework on the web.

## Live Webpage Walkthrough

- **Source:** ReadTheDocs (Python Sphinx) — SQLAlchemy 2.0 AsyncSession Configuration (`docs.sqlalchemy.org/en/20/orm/extensions/asyncio.html`)
- **Recommended Context Mode:** Detailed

**Highlighted Passage:**
> class sqlalchemy.ext.asyncio.AsyncSession(bind=None, *, expire_on_commit=True, autoflush=True, **kw)
Note: When using AsyncSession, the default behavior of expire_on_commit=True means that accessing any attribute on an ORM instance after await session.commit() will trigger an implicit lazy-load SQL query, which fails in async contexts with MissingGreenlet unless attributes are eagerly loaded or expire_on_commit=False is set.

**User Question (Shortcut):** "Show the recommended production async_sessionmaker setup in SQLAlchemy 2.0 to avoid MissingGreenlet errors in FastAPI."

**Vezz me On-Screen Answer:**
Set **`expire_on_commit=False`** on `async_sessionmaker` so Pydantic response serialization after `await session.commit()` doesn't trigger an implicit sync lazy load:

```python
from sqlalchemy.ext.asyncio import create_async_engine, async_sessionmaker

engine = create_async_engine('postgresql+asyncpg://user:pass@localhost/db', pool_pre_ping=True)
SessionLocal = async_sessionmaker(bind=engine, expire_on_commit=False, autoflush=False)
```

**Suggested Follow-Ups:**
- "Write the FastAPI `Depends(get_db)` generator using this `SessionLocal`."
- "When do I still need `selectinload()` even with `expire_on_commit=False`?"

## Step-by-step workflow

1. **Highlight the class/function signature and its 'Note / Warning' callout**: In Sphinx/ReadTheDocs, Docusaurus, and Mintlify, the sharpest production traps live inside `Note:` or `Warning:` admonitions right below the signature. Highlight both together.
2. **Press your shortcut and ask for a complete minimal example**: Reference docs often show signatures (`foo(a, b, *, kw)`) without imports or setup boilerplate. Ask Vezz me for a complete 10-line runnable snippet.
3. **Use it on docs.rs, pkg.go.dev, and localhost dev docs too**: Because Vezz me works via activeTab on any browser tab, it works on `localhost` docs and internal wikis that public search chatbots cannot crawl.

## Why selected-text beats built-in RAG 'Ask AI' doc widgets

Built-in documentation search bots index thousands of pages—frequently mixing deprecated v1 migration guides with v2 APIs.

- Grounds the explanation strictly in the current version's documentation page open on your screen
- Gives you one universal, customizable shortcut (`Ctrl+Shift+X` by default) and your own saved prompt presets across ReadTheDocs, `docs.rs`, `pkg.go.dev`, Docusaurus, and Swagger
- Works on internal Sphinx/MkDocs/Swagger portals running on `localhost` or behind VPN

## Vezz me vs Site-Specific 'Ask AI' Doc Widgets

Comparing a universal selected-text shortcut with embedded vendor doc bots.

| Dimension | Vezz me (Shortcut) | Site-Specific 'Ask AI' Widget |
| --- | --- | --- |
| Site Coverage | Every docs site on the web (ReadTheDocs, docs.rs, pkg.go.dev, localhost) | Only available on sites that pay for a widget vendor |
| Version Accuracy | Grounded in the exact v2/v3 method signature you highlighted | Vector search often blends deprecated v1 docs into answers |
| Custom Prompts | Uses your saved coding style and API Quickstart presets | Locked to the documentation vendor's default prompt |

## Frequently asked questions

### Does Vezz me work on Rust docs.rs, Go pkg.go.dev, and Javadoc?

Yes! Highlight trait bounds on docs.rs, interface definitions on pkg.go.dev, or Python Sphinx signatures on ReadTheDocs and press your shortcut (default: Ctrl+Shift+X).

### Does it work on local documentation running on http://localhost?

Yes. Any standard HTTP/HTTPS page rendered in Chrome or Firefox works with activeTab when you press your shortcut.

### Which prompt preset should I install for API docs?

Install the API Integration Quickstart preset and the Senior Engineer Code Reviewer preset.
