Describe it in a sentence and crisp builds the whole thing. Every page, the data it saves, and sign-in for your users. It runs while you work on it, so you can try every change right away, and you publish it for your users when you are happy with it.

Each of these started as one sentence.

Real, working apps with their own look. The prompt that asked for each one is right underneath it.

A booking page for my yoga studio. Classes by day, spots left, and people can reserve without an account.

A simple sales pipeline for a three person team. Drag deals between stages and show what is still open.

A recipe box where I can save recipes, tag them and search by ingredient or by how long they take.

An invite page for a birthday party with RSVPs, a guest count and a note for the host.

From an idea to a link you can share.

  1. Step 1

    Describe it

    Write what you want the way you would explain it to a friend. Who uses it, what they do, how it should feel.

    A guest list for our wedding where people pick a meal|
  2. Step 2

    Watch it come together

    Every screen, every saved record, every button that works appears as it is made. Nothing to set up, nothing to install.

    • Guest list and meal choices
    • An RSVP form for each invite
    • A page for the two of you
  3. Step 3

    Publish it

    When you are happy with it, publish a stable version for your users at its own address. Keep improving the app; your users only see changes when you publish again. Your own domain is coming soon.

It is never really finished. That is the fun part.

The first version is a starting point. Keep talking to it like a collaborator who never gets tired of small changes.

Change anything by asking
Ask for a new page, a different colour or a whole new feature. It keeps everything else working.
Undo any step, data included
Every reply is a saved version. Go back to any of them, with or without the data, and move forward again if you change your mind.
Open the code when you want to
It is all readable, editable and yours. Change a line yourself and keep chatting.
Make the menu stick to the top when I scroll
Done. The menu stays put on every page.
Let people sign in with Google
Added a Google button to sign-in. Guests keep their answers between visits.
The confirmation email should mention the dress code
Updated the email. Sent you a test copy.

Good questions.

What can I make with crisp?

Web apps of almost any kind: booking pages, internal tools, dashboards, small marketplaces, community sites, personal trackers. They can save data, have accounts and sign-in, send forms and work on phones.

Do I need to know how to code?

No. You describe what you want and ask for changes in plain words. If you do code, everything is readable and editable, and crisp picks up from your changes.

Can I keep changing it after it is built?

Yes, as much as you like. Ask for changes at any time, and go back to any earlier reply, data included, in one click.

Can I use my own domain?

Every app gets its own address when you publish it. Connecting a domain you own is coming soon.

Who owns what I build?

You do. Export the code to GitHub whenever you want and take it anywhere.

How much does it cost?

You can start for free, and no credit card is required. The Free plan includes $3 of AI usage every month, enough to build and try your first apps. Pro is $20 a month. You always see what a request costs while it runs, and you never pay for crisp fixing its own mistakes. See the pricing page for the details.
