Ravenwell

Stop re-teaching your agents.

Ravenwell gives Claude, ChatGPT, and any MCP agent durable, graph-shaped memory they read and write mid-conversation — so nothing you've figured out evaporates between sessions.

or $19/mo · Hosted on our own metal; cancel anytime. You pay for it, so your second brain is never the product.

Cancel anytime · your knowledge exports in full · never trained on.

Your founding rate is locked for life — as long as you stay a member.

Only 100 founding spots — once they're gone, they're gone.

Your knowledge, on our metal — never sold, never trained on.

What you get

Your agent stops starting from zero — it inherits deep context from every past session, research binge, and coding sprint.
Capture insights in the flow of conversation — no separate note app to babysit; your agent writes them as you work.
Recall connected neighborhoods of knowledge, not isolated files or brittle keyword matches — a typed-bond graph, not a folder.
A Zettelkasten-shaped memory that stays fast and usable as years of thinking compound, instead of turning into search sludge.
Your UI is the agent — memory shows up exactly when it's needed, never another dashboard to maintain.

Watch memory appear mid-conversation

Preview

Your agent pulls context from a six-month-old thread, writes a new linked node, and keeps working — without you ever opening a note app.

MCP-native by design — works with Claude Code, Claude Desktop, Cursor, and any MCP agent out of the box.

Built and dogfooded daily by a pseudonymous indie maker who lives in the terminal and relies on it through Claude Code.

Runs on our own metal — never sold, never used to train models; export everything anytime.

Indie-built and user-funded — no VC pressure to bloat into enterprise or sell your thoughts to brokers.

Questions

Is this just another note-taking app?

No. The agent is the interface; you can browse your graph, but there's no dashboard to babysit.

Which agents work with it?

MCP-native: Claude Code, Claude Desktop, Cursor, and any MCP-compliant agent.

Why not Obsidian, Notion, or chat history?

Those demand manual upkeep or trap knowledge inside old conversations. Ravenwell writes and recalls connected memory while you work.

Can I self-host it?

No. It's hosted on our own metal so it stays maintained and your knowledge is never fed to big tech — and your data is still yours: never sold, never trained on, exportable anytime.

What am I paying for?

Persistent agent memory, graph recall, private hosted infrastructure, and an indie builder with skin in the game.
