Your browser has been storing nothing useful for 20 years. I fixed that.
You know that feeling when you read something useful, close the tab, and then spend 20 minutes trying to find it again?
Yeah. I got tired of that.
So I built ContextBridge — a side panel extension that turns your browser into a personal knowledge base.
Here's how it works:
Hit Ctrl+Shift+E on any page. Done. The full content is extracted, cleaned up, and stored locally in your browser. No cloud. No account. No backend to set up.
Then:
Search across everything you've ever indexed — full-text, with highlighted snippets
Chat with any page — ask "what are the main API endpoints?" or "summarize the deployment steps" and get a proper answer grounded in the actual page content
Export to Markdown — single file or ZIP bundle, perfect for Obsidian
History panel — see everything you've indexed with word count, domain, content type
The AI chat uses your own API key (Claude, OpenAI, or Gemini) — no middleman, no markup, calls go directly to the provider.
What makes it different:
Zero setup — works immediately after install
Everything stays on your device (IndexedDB)
Smart extraction — custom parsers for GitHub, MDN, Stack Overflow, arXiv, and more
Auto-detects content type and tags (Python, React, K8s, etc.)
Would love feedback from this community — what would you want from a tool like this?
