Introduction
Daneel AI is a Chrome extension that lets you chat with any website, any local document, or any MCP-connected tool — using AI that runs directly in your browser.
What it does
Section titled “What it does”Daneel AI has three core modes:
Page Chat — Ask questions about the page you’re looking at. Daneel extracts the content (articles, docs, even YouTube transcripts), sends it to an AI model, and streams back an answer. No copy-pasting, no context switching.
Site Search — Index an entire website by its sitemap. Daneel crawls the pages, splits them into chunks, and builds a vector index stored locally in your browser. When you search, it finds the most relevant passages and assembles an AI-powered answer with source links.
Document Vault — Import your own files (PDF, DOCX, TXT, HTML, PPTX, Excel) into named vaults. Daneel embeds them locally and lets you chat with your documents the same way you chat with websites. You can also build a knowledge graph to visualize entity relationships.
What makes it different
Section titled “What makes it different”Privacy by default. The default AI backend (WebGPU) runs entirely in your browser. Your data never leaves your machine unless you choose a cloud provider.
No API keys required. Daneel works out of the box with local inference. Cloud providers like Claude, Ollama, and Azure OpenAI are opt-in.
Multiple AI backends. Switch between four LLM providers depending on your needs:
| Provider | Runs on | Internet needed? |
|---|---|---|
| WebGPU | Your GPU, in-browser | No |
| Ollama | Local server | No (LAN only) |
| Gemini Nano | Chrome built-in | No |
| Claude | Anthropic API | Yes |
| Azure OpenAI | Azure cloud | Yes |
MCP tool calling. Connect remote services (Stripe, Notion, Vercel, Supabase, and more) via the Model Context Protocol. The AI can call tools autonomously across multi-turn conversations.
Agents. Define structured personas with custom system prompts and bound MCP servers for specialized workflows.
Who it’s for
Section titled “Who it’s for”- Researchers who want to query documentation sites without leaving the browser
- Developers who want an AI assistant connected to their tools (Stripe, Vercel, GitHub)
- Privacy-conscious users who want local-first AI with no data leaving their machine
- Teams who need document Q&A over internal files without uploading them to a third party
