The open-source memory for AI agents — it gets smarter the more it remembers, not slower or costlier, and never confidently remembers wrong. Plain files, no database, bring your own model. Works with Claude Code.
SaferSkills independently audited buddy (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

Buddy is a memory and a way-of-working you install on your AI agent. It learns your world, remembers it across every session, and — unlike most memory systems — won't confidently remember things wrong.
Bring your own model. Plain text files, git-friendly, no database. Free (MIT).
Most AI memory gets worse as it grows. The more it remembers, the more it has to cram into its head every time it answers — so it gets slower and more expensive exactly when it should be getting smarter. And when a new fact arrives, it usually just overwrites the old one — so over time it quietly starts remembering things wrong.
one-page notes. However big the brain grows, Buddy only ever opens the contents page plus the two or three notes it actually needs. A brain with 60 notes and one with 60,000 cost about the same to use. More memory = more intelligence, at a flat cost.
silently overwrite — it usually means the two apply in different situations. Buddy keeps both (noting when each applies) or asks you. A true fact is never lost.
non-obvious, hard-won. The brain stays signal, not noise.
so Buddy never re-asks what it already learned about a client or contact.

Install Buddy like setting up a new phone: it asks you a few quick questions, then builds your brain — your folders, your style, your starter card. From then on it remembers your preferences, projects, and people across every session. No re-explaining, ever.
Everything is plain Markdown in one folder you own. You can read it, edit it, back it up, or commit it to git. Nothing is locked in a database.
v1 runs on Claude Code. More apps coming.
git clone this into a new folder. That folder is your workspace.That's it. No database, no extra setup beyond the AI model you already use.
One thing to remember: always start Buddy in this same folder — that's where its memory lives. Buddy makes and sorts every file inside it for you; you never organize anything.
A few habits that make Buddy noticeably smarter over time:
A complete second brain: a five-shelf knowledge library (fixes, how-tos, rules, facts, skills), people & client cards, day-to-day memory, and a built-in habit of saving what it learns and tidying itself up — all curated with your approval.

MIT — free to use, change, and build on. Yours.
Buddy is my son's nickname. Watching him learn a little more every day — and never forget the people who matter to him — is what I wanted to put into software. So Buddy grows up the same way: it gets to know your world, holds onto what matters, and becomes more yours the longer you spend together. I hope it looks after you the way I hope the world looks after him.
