A second brain, built in
ChatGPT forgets you between chats. Ermes runs a real, growing memory on your own private server — organized the way Andrej Karpathy describes building a personal knowledge system, and visible down to every single memory.
Every memory, kept — on your server, not ours
Everything your agent learns — conversations, the WhatsApp and Gmail context you choose to connect, facts you ask it to remember — lands in a semantic memory (Postgres + pgvector) on a dedicated server that belongs to you. It recalls by meaning, in any language: ask about “that invoice thing from a few weeks ago” and it finds it, no exact words needed.
Living notes that rewrite themselves
Raw memory alone piles up. So your agent also maintains living pages — one per person, project, and recurring topic in your life — and rewrites them as things change instead of appending forever. It's the pattern Andrej Karpathy has described publicly: keep an append-only record of everything, and let an LLM maintain the distilled, current wiki on top. (His idea; our implementation — Ermes isn't affiliated with or endorsed by him.)
The part we refuse to compromise on: every page shows its sources. Tap any statement and see the actual memories it was built from. And when you tell your agent to forget a source — WhatsApp, Gmail, anything — every page built on it is erased in the same breath. Real deletion, not a policy promise.
See what your agent knows
The Memory Atlas shows the whole thing as a living orb: every memory a star, placed by meaning — a WhatsApp message and an email about the same project sit side by side. Lines are meaning-links. When your agent recalls something, you see the memories fire like synapses; when it learns something new, you watch the star appear and wire itself in. Search by idea and the map lights up. Click any star: why is this here, what used it, what does it connect to.
The demo above runs on example data. Your own atlas is private to you — your agent can send you a secure link to it anytime: just ask “show me my memory map”.
Compounding, not amnesia
A tool that remembers becomes more useful every single week — it knows your people, your projects, your preferences, your history. A tool that forgets starts from zero every morning. That difference compounds. That's the whole bet.
