Crevio builds more than marketing websites. Describe a tool your business needs and Crevio’s AI builds you a real, working web app — one that does something, not just one that shows something. Same as everywhere else in Crevio: you say what you want in plain words, and Crevio makes it. You never touch code, servers, or hosting. You talk to Crevio like you would a developer who never sleeps, and it builds, publishes, and looks after the app for you.

​
Why you’d use this

  • You need a tool, not just a page. Something people can actually use — book a slot, log in to an account, look something up, calculate a result.
  • You are not technical. No code, no databases to wire up, no hosting to buy. Crevio handles all of it.
  • You want it to keep up with you. As your business changes, you just ask Crevio to change the app — no rebuilding from scratch.
The golden rule of Crevio still applies: when in doubt, just ask. If you can describe the tool in a sentence, Crevio can usually build it.

​
What you can build

Apps are open-ended, but here are common ones to spark ideas:
Not sure whether something counts as an “app”? Just describe what you want it to do — “let people book a 30-minute call and pay a deposit” — and Crevio figures out the rest.

​
Ask Crevio to build it

1

Describe what it should do

Open Crevio and explain the tool in your own words — who uses it and what happens when they do. For example:“Build me a booking app where clients pick a service, choose a time from my calendar, and pay a deposit up front.”
2

Add the look and feel

Mention a style if you have one in mind, or leave it out and Crevio will match it to your business.
3

Let Crevio build it

Crevio assembles the real, working app — the screens, the logic, and the data it needs to remember. You can watch the progress as it goes.
4

Try it out

When it’s ready, Crevio shows you a preview. Click around and use it like a customer would. Nothing is final — anything can be changed by asking.

​
It’s a real app, not a mockup

The apps Crevio builds are the real thing:
  • They remember data. Bookings, submissions, accounts, and anything else your app collects are saved and stay put.
  • They’re hosted for you. Crevio publishes the app and keeps it online — no separate hosting to set up or pay for.
  • They live on your web address. Use the free yourname.crevio.app address or connect your own custom domain.
  • You control who gets in. Make an app public, limit it to signed-in customers, or keep it to your team while you build. See choosing who can see your site.

​
Change anything by asking

Once your app exists, improving it is just a conversation — the same as with your website:
  • “Add a cancellation option to the booking flow.”
  • “Send me an email whenever someone signs up.”
  • “Show the busiest days at the top of the dashboard.”
  • “Let members edit their own profile.”
Crevio makes the change and shows you the result. If it’s not quite right, ask again.

​
If something goes wrong

Tell Crevio what should happen instead, in plain words — “when someone books, it should also ask for their phone number.” Crevio adjusts the behavior. The clearer you are about what should happen, the closer the next version gets.
Just ask Crevio to undo it or try another approach: “That’s not what I meant — go back to how it worked and instead add the field to the second step.”
Start with the outcome: what should a person be able to do, and what should happen when they do it? You can also ask Crevio for ideas — “What kind of app would help a cleaning business take bookings?” — and build from there.
