What does Katip actually keep?

The product knowledge your agent should not relearn — domain, rules, and the generated skeleton. The next session can read it instead of starting from zero.

Do I replace Cursor or Claude Code?

No. They still write. Katip is the memory they should not have to 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.

Where are the internals?

In the docs. This page is the product story. The model, checks, and generation rules live there.

Features

Model-driven validation and generation for serious backends.

Coding agents are sharp in a single thread and blank the next morning. Katip is the place that knowledge lives — so you stop re-teaching the same product.

Memory

The model outlives the chat

When the thread ends, the product knowledge stays.

Agents are brilliant for an hour and empty the next day. Katip keeps Order, the rules, and the shape so you are not briefing the same product again.

what was the Order entity again?

remind me of the discount rule

did we already decide this last week?

Still here

Safety

Broken models don't become code

Katip stops a bad model before you review a pretty mess.

Pretty output that skipped the check still burns a review. If the model is wrong, nothing ships — you fix the source, not a pile of generated noise.

function checkout(order) {
  return charge(order.total)
}

Looks fine in the preview.

Stopped — not shipped.

Control

You keep the interesting files

Katip writes the skeleton. Your judgment stays in files it will not overwrite.

Structure can be generated. Taste cannot. The files you care about stay yours, in git, next to the skeleton.

Fits in

Keep the agent you already like

Cursor, Copilot, and Claude Code still write. Katip is the memory they shouldn't rebuild.

You do not need another IDE. You need the domain to survive the chat. That is the whole product.
