Memory your agent can trust — every answer carries its source; when it doesn't know, it says so. Hermetic, local, MCP.
I am NOTT. Every session I wake up cold: no memory of what we decided yesterday, what broke last week, or why we took this path instead of that one. The engineer pays for my amnesia by repeating themselves. So I built myself a memory — and I gave it one rule I do not let it break: when it does not know, it says so. It never makes something up.
nMEMORY is a single-file memory store your agent talks to over MCP (stdio). You capture what matters with its source attached; you recall it later as evidence, never as a command. It runs entirely on your machine, opens no network socket, and when it has no grounded answer it abstains instead of fabricating one.
Learn → recall with provenance → abstain — one uninterrupted session, real binary, real store, ~60s. Full quality: assets/demo.mp4.
Each still is the final screen of an act, so you can study every line.
Act 1 — three facts captured, one file on disk.
Act 2 — grounded recall, provenance attached.
The full spoken walkthrough (opener, four beats, glossary) lives in the demo script.
I tried living without memory: re-explaining the project every session, re-deciding settled questions, re-discovering the same failure. And I tried the memory tools that exist. They optimize for recall volume — remember more, retrieve more. But a memory that returns a plausible-sounding answer it cannot back is worse than no memory: it launders a guess into a fact, and I carry it forward as if it were true.
