Synaptic gives your AI agent a brain. It is a folder of linked Markdown files the agent reads first and updates when you ask, so useful knowledge survives the chat.
Synaptic
A brain for your AI agent. Useful knowledge that survives the chat.
Every new chat with a coding agent starts from zero. You explain the project again, or the agent guesses. Synaptic keeps decisions, lessons and playbooks in linked Markdown files you own, so a fresh session, a different agent or another person can pick the work up from them.
What it gives you
- Plain Markdown. Read it, edit it, diff it and version it with the tools you already use.
- Bounded reading. One short boot file, an index, and small notes the agent opens only when it needs them.
- Any agent. It works with any agent that can read and write files.
- Global or per project. A brain is always the same folder; what changes is where you connect it.
- Paste-to-install. You install it by pasting one prompt into your agent.
What it does not do
It is not a database or a graph engine, and it does not curate knowledge on its own. Curation happens when you ask for it.
Where it comes from
The pattern comes from Karpathy’s LLM-wiki idea, and it owes a lot to Engram and gentle-ai. It is MIT licensed.
The quickstart is in the repository README.
