A durable place for the product knowledge your coding agent should not relearn. The next session starts from the model, not from zero.

Do I replace Cursor or Claude Code?

No. They still write. Katip is the memory they should not rebuild every Monday.

What can I generate today?

A NestJS structural skeleton you can keep in git. Full runnable apps and more stacks are on the roadmap — we will not sell them as shipped.

Can I buy a seat now?

Not yet. Join the waitlist. We will write when Pro opens.

Features for what stays. How it works for two living demos. Docs for the internals.

Katip — Model-Driven Agent for serious backends

Your agent is sharp for an hour and blank the next morning. Katip keeps the product knowledge so Tuesday starts ahead. Not Clerk.com authentication.

Monday feels like week one

Coding agents rediscover the same product every session. Katip is the memory they should not rebuild.

Without a model

Domain rediscovered every session
Rules live in the chat
Pretty output skips the check
Review burns on the same mess

With Katip

Katip

The model outlives the chat
Next session reads the product
Broken models don't become code
You keep the files that matter

The chat — Gone by morning

The model — Still there

Describe it once. Ship from there.

A short loop — then the rest of the page. Living demos live on How it works.

01
Write what you mean
The domain and the rules — once.
02
Katip holds it
So the next session can read it.
03
Start ahead next time
No rediscovering the same product.

This is for you if

You already pay for an agent
Keep Cursor, Copilot, or Claude Code. Katip is memory, not another seat.
Mondays feel like week one
Same entities. Same rules. Same review. The chat should not be the source of truth.
You want files you can keep
A skeleton in git. Your judgment in files Katip will not overwrite.

This is not: Another chat that forgets on close · A drag-and-drop app builder · Clerk.com authentication

Questions

What you get today

Core engine + Katip surfaces for honest Developer Preview.

4-layer pipeline

Fail closed
Strict schemas and purity checks — unknown fields do not pass.
Hybrid generation

Agent-ready memory
Formal Origin so coding agents stay inside product boundaries.
