Your brain's
operating system
A living knowledge graph that learns from how you think. Connect Obsidian, Claude, and your own notes into one neural network that remembers — and forgets — like you do.
Memory isn't flat.
Your PKM shouldn't be either.
Cyton models the same five memory systems neuroscientists have identified in the brain. Every note you take is classified, decays realistically, and consolidates over time.
Your notes.
Connected automatically.
Every conversation you have with Claude Code shapes your graph. When topics come up together in a session, Cyton strengthens the edge between them. Topics you stop discussing gradually decay. No manual linking. No tagging required — your thinking does the work.
Your notes,
enriched automatically.
On the Free plan, Cyton's cloud Haiku API analyses your vault in the background and enriches your graph — extracting concepts, linking ideas, and surfacing connections you'd miss. No setup.
On Pro, connect your own LLM via Claude Code MCP. Your model — Sonnet, GPT-4, Gemini, whatever you run — does the same enrichment entirely locally. Your data never touches our servers.
Your vault.
Cyton watches it.
Point Cyton at your Obsidian vault and walk away. Every save is processed instantly — concepts extracted, nodes created, synapses updated. No plugins, no manual steps, no disruption to your existing workflow.
Simple, honest pricing.
Free forever for individuals. Pro unlocks the full neural stack.
