Contextbolt
You save great stuff.
Then you never find it again.
Captures your X, Reddit, and LinkedIn bookmarks. AI organises everything. MCP connects them to your AI tools.
The problem
Three platforms. Zero search.
You keep saving posts because they're valuable. But every platform makes it impossible to find them later.
Bookmark search is broken
Basic keyword matching. No semantic search. Hundreds of bookmarks with no way to filter or find what you need.
Saved posts are a black hole
There is literally no search for saved posts. You have to scroll through everything manually. Good luck finding that comment from 6 months ago.
Good posts disappear forever
There's no easy way to bookmark LinkedIn posts as you scroll. By the time something valuable resurfaces, you've forgotten it existed.
How it works
Three steps. All automatic.
Install it. Visit your bookmarks. Done.
Add the Chrome extension. Open your bookmarks on X or Reddit and ContextBolt captures everything automatically. On LinkedIn, a save button appears on every post so you can bookmark anything in one click. No importing, no API keys, no setup.
AI tags and organises everything
Every bookmark is auto-tagged by topic and embedded for semantic search. They're automatically grouped into clusters so you can see patterns in what you save.
Search instantly. Connect to your AI tools.
Search across all your bookmarks at once with AI-powered semantic search -- free for everyone. Pro users get an MCP endpoint that connects their bookmarks to Claude, Cursor, and any MCP-compatible AI agent as live context.

MCP Integration
Your bookmarks, inside any AI agent
MCP (Model Context Protocol) is the open standard that lets AI agents access external tools. ContextBolt Pro gives you a personal MCP endpoint. One line of config and your AI can query your entire bookmark collection as live context.
Live context, not a static export
Your AI pulls from your bookmarks in real time during the conversation. Nothing to paste. Nothing to upload. It just knows.
Works with any MCP-compatible agent
Claude Desktop, Claude Code, Cursor, Windsurf -- if it speaks MCP, ContextBolt works with it. Your knowledge layer, everywhere you build.
Your agents get smarter
Your existing AI agents already understand your codebase, your files, your context. Bookmarks make them sharper still -- giving them access to what you found important.
One line to connect
Your entire bookmark collection as an AI context layer
Add your personal MCP endpoint to any compatible AI client. Ask "what did I save about rate limiting?" mid-conversation and get an answer -- with a link back to the original post. No switching tabs. No digging through folders.
Pro tip: your bookmarks are a curated feed of things you found important. That's exactly what an AI agent needs to understand how you think.

FAQ
Common questions
What is ContextBolt?
ContextBolt is a Chrome extension that captures your bookmarks from X (Twitter), Reddit, and LinkedIn into one searchable AI knowledge base. It automatically generates topic tags and clusters for every bookmark using AI. Pro users get an MCP endpoint that connects their bookmarks to AI tools like Claude Desktop, Cursor, and Windsurf as live context.
How much does ContextBolt cost?
ContextBolt has a free tier with 150 bookmarks, AI tagging, topic clustering, and semantic search. Pro costs £4 per month and includes unlimited bookmarks, a personal MCP endpoint, and encrypted cloud sync.
How does ContextBolt access my bookmarks?
It's a Chrome extension that runs locally in your browser. For X, it intercepts the bookmarks API when you visit your bookmarks page. For Reddit, it reads your saved posts. For LinkedIn, it adds a save button to feed posts. No passwords or API keys needed.
Is my data stored on your servers?
All bookmark data stays in your browser by default (IndexedDB). The only thing sent to our servers is text content for AI processing (tagging and embeddings). Pro users can optionally turn on encrypted cloud sync.
What platforms does it work with?
X (Twitter) and Reddit bookmarks are captured automatically. For LinkedIn, ContextBolt adds a save button to posts in your feed. All three platforms are searched together in one place. Works with Chrome, Brave, Arc, Edge, and any Chromium-based browser.
How is this different from Twitter's bookmark search?
Twitter's search is basic keyword matching on one platform. ContextBolt gives you semantic AI search across X, Reddit, and LinkedIn at once. Plus an MCP endpoint that connects your bookmarks to any AI agent as live context.
What is the MCP endpoint?
MCP (Model Context Protocol) is an open standard that lets AI agents access external data as live context. ContextBolt Pro gives you a personal MCP endpoint. Add it to Claude Desktop, Claude Code, Cursor, Windsurf, or any MCP-compatible client -- your AI can then search your entire bookmark collection mid-conversation, without you having to copy or paste anything.
Can I use it for free?
Yes. Free includes 150 bookmarks with AI tagging, topic clustering, and semantic search. Pro is £4/month for unlimited bookmarks, MCP endpoint, and cloud sync.
