The premise

Most agent memory guesses. This one is accountable.

Vector search hands back a blurry blend and hopes it's close. When it isn't, the model fills the gap with something that sounds right. braineon is built the opposite way.

✗

The usual wayEmbed everything, retrieve a fuzzy top-k, let the LLM smooth over the seams. A confident answer, no way to check it, and a bluff when recall is thin.

✓

The braineon wayScore a catalogue with no model in the path. Return one file, one section, and the exact signals that won. Below the confidence floor, return an honest miss — never an invention.

The memory model

Four layers, one answer

Your files stay the source of truth. Everything above them is disposable, derived state that rebuilds from the files at any time. Tap the stack to pull it apart.

Files

plain markdown · you own it

Catalogue

deterministic keyword index

Recall

one file · one section

Trace

Watch it think

One clear winner. Every time.

Ask a question and watch the memory light up. One section pulls ahead, and you see exactly why it won — no mystery, no maybe.

Two ways to remember

Rock-solid by default. Uncannily smart when you want it.

One engine, two gears. The default gear is instant and exact. The second reads what you meant, not just what you typed.

Default

Exact recall

No model in the loop. The same question always returns the same answer — instantly, for free, on your machine.

Meaning-aware

Ask it your way. On-device understanding catches the paraphrase, the synonym, the idea behind the words — still local, still yours.

Why you can trust it

Guarantees, not vibes

≡

Files are the source of truthPlain markdown on disk, a git repo by default. Every index is derived and disposable — rebuild it any time.

◎

A trace on every answerSee exactly which signals fired and what they scored. explain shows the full breakdown — no black box.

∅

Honest missesBelow the confidence floor you get a structured miss with the nearest candidates — never a hallucinated hit.

⛌

Refuses to store secretsAn API key, token, or private key is blocked before any file is written — a git history is permanent.

⌂

Local-first, alwaysThe recall path never touches the network. No telemetry, no server you don't control.

⌘

Native to your agentAn MCP server exposes recall, remember, explain and status straight into Claude Code and other hosts.

Four zeros

Everything you were told to live with — gone.

No token bill. No black box. No lag. No lock-in. Memory finally has nothing to hide.
