Side panel watches your conversation and surfaces related memory
The research you did last month. The decision you worked through last week. The solution you found after two hours of back-and-forth. Gone — unless you remember to go looking for it.
And if you've been using both Claude and ChatGPT? Good luck finding which platform has the conversation you actually need.
AI tools have a memory problem. CapsuleBase solves it.
Everyone is talking about who has the best AI tools. The real question is who has the best AI memory. Tools are commodities. A competitor can buy the same tools tomorrow. They can't buy three years of accumulated thinking.
A person running CapsuleBase for three years doesn't just have a tool advantage. They have a knowledge advantage that can't be replicated — the reasoning behind decisions, the dead ends that saved time, the context that made the right answer obvious.
The old CEO retires. The developer who knew why every decision was made wins the lottery. The thinking that took years to build — gone. Unless it was captured while it was happening. This is the problem CapsuleBase solves.
Chrome extension saves any Claude conversation instantly. Bulk import your entire Claude or ChatGPT history in minutes.
Text and semantic search combined. Find what you mean, not just what you typed — even months later.
CapsuleBase connects to Claude Desktop via MCP. Claude quietly searches your history before answering — richer responses every time.
Every saved conversation gets an auto-generated title, summary, tags, and category via Claude API. Organized without effort.
Import conversations from Claude and ChatGPT into one searchable local archive. One place for everything.
PostgreSQL + pgvector on your machine. No cloud sync. No account required. Your knowledge never leaves your device.
Click the CapsuleBase extension to save any AI conversation to your local knowledge base.
Find anything across all your saved conversations with fast hybrid text and semantic search.
Claude automatically pulls relevant context from your history — richer, more informed answers every time.
Most tools that claim to protect your privacy still send your data somewhere for processing. CapsuleBase is different. The database is yours. The search index is yours. Everything runs on your machine.
Hosting your thinking on someone else's AI platform is like selling on Amazon while Amazon watches what sells. Local first isn't the alternative to the cloud — it's the grown-up response to what the cloud turned out to be.
No subscription that can disappear. No vendor who can change the terms. Your knowledge, permanently yours.
Requires Python 3.11+ and an Anthropic or OpenAI API key.
