Let's Talk

Enzyme is built from a workspace that looked like yours — half-finished tags, abandoned systems, and the suspicion that the mess was pointing somewhere.

What 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.

Why not just use Claude's large context window? ▼

Context windows work for one-shot exploration of a small corpus. Dump in 50 notes, ask a question, get an answer. They don't replace a persistent conceptual index for three reasons:

Accuracy degrades with length. Research from Stanford and Berkeley shows 30%+ performance drops in the middle of long contexts. Effective capacity is roughly 60-70% of the advertised maximum. The degradation compounds — it gets worse the longer the context.

Cost scales linearly. Requests exceeding 200K tokens carry a 2x input premium. For a vault of 2,000 notes, you'd pay that premium on every session. Enzyme indexes once (cents per user) and queries are free after that.

No persistence. Context windows reset every session. Enzyme's conceptual map persists and updates incrementally as you write. The agent doesn't rediscover your vault from scratch each time.

Why is it free? ▼

The engine is free for individuals. Revenue comes from 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.
