About
The memory layer for the AI era
We believe AI conversations hold some of your most valuable thinking. They shouldn't disappear.
The problem we're solving
Every day, millions of people have breakthrough moments inside AI chatbots — a clean explanation of a complex topic, a solution to a hard problem, a framework that changes how they think. Then they close the tab, and it's gone.
Chat history doesn't scale. You can't search across conversations. You can't see patterns. You can't resurface the insight you need at the right moment.
Our solution
Memory Capsule sits quietly in your browser, watching as you learn. When you have an insight worth keeping, it captures it, extracts the key ideas, tags it intelligently, and makes it searchable — instantly.
Think of it as a second brain that specifically understands how you think in conversation with AI. Not just a bookmark manager. An actual memory layer.
Built in public
Memory Capsule is open source. We believe the tools that handle your most personal knowledge should be transparent, auditable, and community-owned. Follow our progress on GitHub.
Privacy first
Your memories never train our models. You own your data completely.
Open source
Full transparency. Fork it, audit it, self-host it.
Instant recall
Search across all your AI learnings in milliseconds.
Works everywhere
