nMEMORY
Local memory for AI agents that admits when it doesn't know.
nMEMORY is a single-file, hermetic memory your coding agent talks to over MCP. Every answer carries its source; when there's no evidence it abstains instead of hallucinating. One Rust binary, one SQLite file, zero network. Open source, AGPL-3.0.
15 years shipping software. The last 12 months, nothing but AI — full-time, all in. What
came out is 17 tools that make a generic coding agent actually mine; I'm releasing them
one at a time, and this is the first.
My coding agent woke up amnesiac every session — I re-explained the project, re-decided
settled questions, re-found the same bug. So I built it a memory with one rule I don't let
it break: when it doesn't know, it says so. It never invents an answer.
Recall returns one of three honest outcomes — grounded (evidence with its source),
missing_evidence (matched but every match excluded, with per-reason counts), or abstain
(nothing matched). There is no fourth "here's my best guess" branch; you can read the
source and confirm the code path doesn't exist. Capture is provenance-mandatory: no source, no storage. A disproven fact gets a `falsifies` edge and stops grounding recall — the memory remembers being wrong.
It runs entirely on your machine: one Rust binary, one SQLite file, compiled without a
networking stack (strace shows zero socket() calls). MCP over stdio, so it plugs into Claude
Code / Codex / any MCP client. AGPL-3.0.

I'm one engineer (n=1). Happy to go deep on the design — especially the "advisory, not
authority" stamp that makes stored text unable to hijack the agent. #2, nSOUL (the
engineering core the rest sit on), is already up; 15 more to come.

Who hunted nMEMORY?
nMEMORY was hunted by tiago. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
