Can an AI really validate a startup idea?

It can score it against what usually goes wrong — unclear problem, no urgency, no willingness to pay, an MVP that is really a full product — and it can be honest about it, which friends and family cannot. Real validation happens with customers; this tells you what to test first.

What is a Lean Canvas?

A one-page business model: problem, customer segments, unique value proposition, solution, channels, revenue, costs, key metrics and unfair advantage. The tool fills one from your description.

Is it only for startups?

No. Internal tools and side projects benefit from the same questions; pick "internal tool" as the business model and the monetisation score is replaced by savings.

Yes. No account, no card, no watermark. Each visitor can run a tool a few times an hour; the limit exists only to keep the tools fast for everyone.

What happens to what I type?

Your input is sent to an AI model to produce the result and kept with the result for 90 days so you can come back to it. It is not used to train anything, and result links are unlisted.

Can I use the result outside Chattee?

Of course. Copy it, download it, share the link. "Build this with Chattee" is there if you want the app built, not a condition.

How it works

edit_note

Describe the idea

What it is, who pays, how you think you will make money. "Not sure yet" is an allowed answer.

fact_check

Get scored

Problem clarity, market and urgency, competition, MVP complexity and monetisation, 1–10 each, with the reasoning.

rocket_launch

Get the MVP

A Lean Canvas, the smallest version that tests the riskiest assumption, the risks — and a build prompt for that MVP.

What honest validation looks like

A 6 is average. A 9 is rare. The reasoning is the useful part.

psychology

The riskiest assumption first

Most ideas die on one assumption. The MVP scope is built to test that one, not to be a smaller product.

compare

Competition, named

"There is nothing like it" is usually wrong. The scoring says what people use today instead.

payments

Who actually pays

An idea everyone loves and nobody pays for scores low on purpose.
