What Sherpa does
Sherpa turns any help center or documentation site into a searchable, question-answering index that lives 100% on your computer. Point it at a docs site, and it crawls pages, builds a search index in your browser, and answers questions with clickable citations for every answer.
Key Features
- Local & Serverless — Bundles its embedding model and runtime inside the extension. Zero backend servers, zero telemetry, zero per-query cost.
- Internal & Authenticated Docs — Crawls reusing your existing browser session, enabling instant Q&A on private wikis and customer-gated help centers.
- Grounded Answers & Citations — Answers stream in with numbered citations linked to exact source passages. Flags when the index cannot answer a question.
- Content Gap Reports — Identifies queries your documentation failed to answer, exportable as CSV or Markdown to improve docs coverage.
- Flexible Search Modes — Choose extractive mode (no AI model required), Chrome built-in Gemini Nano, or your custom OpenAI/Claude/Gemini API key.
Who it's for
Developers, support engineers, technical writers, and teams who navigate complex documentation or internal wikis daily. Sherpa is free on the Chrome Web Store and runs in any Chromium browser.
FAQ
Is Sherpa free? Yes — free to install from the Chrome Web Store.
Does Sherpa send indexed pages to an external server? No. Indexing and storage happen entirely in your browser. The only network calls are fetching the pages you ask it to crawl.
Can I crawl private internal wikis? Yes. Sherpa uses your browser session to access gated documentation without needing server API tokens.
