About Idea to App
Turn your app idea into a working app with AI: write a one-page spec, scope a first version, build it with logins and a database, and get your first users.
What is Floot?
Floot is an AI app builder that turns an app idea into a working app with sign-up, a database and hosting, so founders can put a first version in front of real users before hiring anyone.
Most app ideas stall between the idea and the first version: the spec is fuzzy, the scope is too big, and the developer quote is too high. With AI you can build a first working version yourself, put it in front of real people and learn what to build next. This site walks through that path.
Why build it with Floot?
The distance between an idea and a first working version used to be a developer’s quote. Now it’s an afternoon of describing and testing. The founders who learn fastest are the ones who get a real version in front of people soonest.
How Floot works
Add Floot to the AI you already use from its listing in the Claude or ChatGPT directory, or the Cursor Marketplace. There is no address to copy.
- Write one page: who it’s for, the problem, the one thing the app must do.
- Cut it to a first version you could test in a week.
- Build it with Floot and try it with five real people.
- Fix what they trip on, then decide what to build next.
For example, you could start with this prompt:
Build a first version of my idea: a shared shopping list for roommates. People sign up, create a household and invite others by email. Anyone can add items; checking one off shows who bought it and how much it cost, and the app keeps a running balance of who owes whom.
What can you use Floot for?
- Side-project founders: Test an idea in evenings and weekends without a big bill.
- Experts with a niche: Turn what you know about an industry into a tool people pay for.
- Small business owners: Build the app your customers keep asking for.
Who is it for?
First-time founders and anyone with an app idea and no developer.
Who founded Floot?
Floot was founded by Yujian Yao, who is its CEO.
Is Floot backed by Y Combinator?
Yes. Floot is backed by Y Combinator and was part of the Summer 2025 batch (YC S25).
What does Floot include?
- From a description to a working app: Describe the idea in ChatGPT, Claude or Floot’s editor and watch a live preview as it’s built.
- Plan before you build: Floot can write a build plan you approve first, so the first version matches what you meant.
- Real logins and data: Users sign up and their data is saved in Postgres, so you can test with real people.
- Payments when you’re ready: Add checkout or a subscription through Floot Payments, paid out via Stripe.
- Web and phone: Share a link first; publish to the App Store and Google Play later.
- See who uses it: Built-in visitor analytics on the published app.
Frequently asked questions
How do I turn an app idea into a real app without coding?
Write a one-page spec, cut it to a small first version, and build it with an AI app builder like Floot that includes logins, a database and hosting. Then test it with real people.
How long does a first version take?
A focused first version can often be built over a weekend; testing it with users takes longer and matters more.
Should I protect my idea before building?
Ideas are rarely copied before they work. Check that your name is free and keep building; the guide on protecting your idea covers what actually matters.
What does it cost to try?
Floot is free to start. Pro is $25 a month when you need more.
