Your vault already knows what matters. The guide helps you hear it.
Enzyme ships with a default guide that works out of the box. But the guide that knows your threads, your tags, the tensions you keep returning to — that one takes sitting with your vault together.
Guide development
Your guide tells Enzyme what to care about — which tags carry weight, where the live threads are, how your folders hold meaning. The guide shapes which questions surface from your vault during indexing — the lens through which everything speaks back. We sit with your vault and configure it to see your archive the way you do.

Point your vault's lens at material you haven't read yet. Research papers, new fields, unfamiliar territory — encountered through the patterns your own thinking has already formed.
Enterprise
CustomShared vaults, team catalysts, API access, and domain-tuned extraction.
- ✓ Shared vaults & team catalysts

- ✓ Domain-tuned extraction
- ✓ Guide development at the organizational level
Enzyme is built from a vault that looked like yours — half-finished tags, abandoned systems, and the quiet suspicion that the mess was pointing somewhere.
Join the communityWhat catalysts enable
Enzyme surfaces catalysts from your structure. AI uses them to help you find your direction.
For researchers
Fifteen years of marginalia. Your questions have changed, but you keep returning to the same tensions. Enzyme shows you the thread you've been pulling.
For personal apps
User context that grows with them: preferences, history, the things they've saved. Your app helps them recognize what matters to them.
For creative partners
Client taste, surfaced from their saves and past choices. The agent knows their direction when proposing new work—no manual lookup required.
Frequently Asked Questions
What are catalysts? ▼
Catalysts are the questions, themes, and insights Enzyme surfaces from your tags, links, and folder structure—even incomplete ones. They're what your scattered system was pointing to all along. They help AI understand your direction—which threads matter, which questions are yours. Your half-finished organization becomes a compass.
What's a vault? ▼
Your vault is your collection of notes (an Obsidian vault, a folder of markdown files, or your Apple Notes). It's where your thinking accumulates over time, and where your graph lives.
What's the guide? ▼
The guide tells Enzyme what to care about — your tags, folders, priorities, the weighting that makes catalysts feel personal rather than generic. Two people with the same vault and different guides get different catalysts. Enzyme ships with a default guide that works out of the box. You can customize it, or we can help you build one.
Is my data private? ▼
Enzyme runs locally on your machine. Your vault files stay on your device. Catalyst generation uses your own API key (OPENAI_API_KEY) — we never see your data.
See our privacy page for the full picture.
Why is it free? ▼
The engine is free for individuals. Revenue comes from guide development, apply engagements, and enterprise licensing for teams that need shared vaults and domain-tuned extraction. The individual engine stays free because that's where the community and feedback loop live.
