Common questions
Is Epiphany safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

Epiphany
One private, local memory your AI tools share.
Every AI you use forgets you the moment the chat ends. You re-explain the same context over and over, and when a session dies, the reasoning behind it is gone for good. Epiphany fixes that. It's a single memory that lives on your machine, that Claude, Grok, Gemini, and more all read from and write to, so what you tell one, the others already know.
- Local-first. Your brain is a file on your disk. Nothing leaves the machine. No account, no cloud, no company owns your memory.
- Cross-model. One shared memory across Claude (Desktop + Code), Grok, Gemini, Cursor, Antigravity, Warp, Hermes, and Perplexity. Tell Grok something, ask Claude about it.
- Real memory, not bullet points. Thoughts carry their reasoning and connect into a graph, so recall returns *why* something is true and what it followed from, not a lone fact. Ask a follow-up and it holds the thread.
- Never lose a session. A background watcher reads the transcripts your tools already write to disk and files every session into the brain in near-real-time, even ones that crashed before anything was saved.
How it works
Epiphany is a local MCP server plus a tiny CLI.
- It runs a small server on your machine that exposes two tools to any AI client:
recallandremember. epiphany connectwires that server into each AI tool, in the tool's own config format, and installs a standing rule so the agent reaches for your memory on its own.- Memories are embedded on-device (a local model, nothing sent anywhere) and stored in SQLite. Agents wire explicit reasoning connections between thoughts (
because,builds_on,part_of, ...), and recall walks that graph to reconstruct the whole thought-string. - A background watcher sees your tools' session logs the moment they change and sweeps them into the brain, so nothing is ever lost.
The intelligence stays in the models you already use. The brain itself is a fast, private librarian: it holds, connects, and recalls. It never phones home.
Quickstart
Requires Node 18+.
npm install -g epiphany-mcp # puts the `epiphany` command on your PATHOr build from source:
git clone https://github.com/GATSV-tech/epiphany.gitcd epiphany npm install npm run build npm link
Wire it into the tools you use, then fully restart each one:
epiphany connect claude-codeepiphany connect grok epiphany connect gemini epiphany list # see all supported tools
Turn on the background "never lose a session" sweep:
epiphany scheduleThat's it. Now talk to any connected AI. It will recall what you've told the others and save what's worth keeping, on its own.
Run epiphany with no arguments any time to open the dashboard and look inside your brain.
Supported tools
| Tool | Connector | Standing rule |

Commands
epiphany connect <tool> wire Epiphany into an AI tool (connector + rule)epiphany rule update just the standing rule for a tool epiphany list show supported tools epiphany dash open the interactive dashboard (browse, search, curate) epiphany graph see your whole brain as an interactive visual graph epiphany weave wire the reasoning connections between related memories (optional; uses your LLM key) epiphany status show brain size, connected tools, and auto-capture state epiphany ingest sweep session logs into the brain now (one-shot) epiphany watch run the near-real-time watcher in the foreground epiphany schedule install the background watcher (captures sessions as they happen)
Your brain lives at ~/.epiphany/brain.db. It's yours. Back it up, inspect it, delete it, it's just SQLite.
Roadmap
Epiphany's core, local cross-model memory with reasoning graphs and automatic capture, works today. Next:
- More session sources for the ingestor (Claude Code, Cursor transcripts).
- Reconciliation. When a fact changes, the brain flags the conflict and you confirm the update, so memory self-corrects instead of piling up contradictions.
- Cloud bridge. An optional relay so cloud-only surfaces (ChatGPT on the web, wearables) can reach your local brain.
- Desktop app. A download-and-run shell for people who don't live in a terminal.
