Startup.ai is a web tool that combines idea evaluation with AI app generation. You start by typing a description of what you want to build, for example a waitlist page, a personal portfolio or a restaurant site, and the builder drafts a working first version without code. A live preview updates as you request changes in chat, and views for preview, cloud and code are available. When ready, the app can be deployed to a public URL. Alongside the builder, an evaluation feature rates an idea out of ten overall and on market, problem and revenue, and an idea browser lets you search concepts that have already been assessed. Usage is metered in credits: the Free plan gives one credit per day and one branded published site, while Pro provides 100 credits per month, unbranded publishing and private ideas. ## Key features - **AI Builder**: Drafts the first version of an app or site from a written description of the idea. - **Live Preview**: Shows the app updating as you describe changes, so edits can be checked immediately. - **Idea Evaluation**: Scores a concept out of ten overall and across market, problem and revenue. - **Idea Browser**: Lets you search a catalogue of startup concepts that the system has already evaluated. - **One-Click Publishing**: Deploys the finished app to a permanent public address served over HTTPS. - **Private Ideas**: Keeps ideas out of public view; this option belongs to the Pro plan. ## How Startup.ai works 1. **Enter the idea**: Describe the product, who it is for and what a person can do in the first version. 2. **Check the preview**: Watch the generated app in the live preview and ask for changes. 3. **Publish**: Deploy the app and share its public URL. ## Use cases - **Waitlist Pages**: Put up a signup page with an email form and FAQ to gauge interest. - **Portfolio and Link-in-Bio Sites**: Generate a simple personal site from a short prompt. - **Local Business Sites**: Create a web presence for a restaurant or similar business. - **Screening an Idea**: Get a score for a concept before spending time building it. - **Finding Something to Build**: Browse evaluated concepts for inspiration. ## Things to know - **Credits meter usage**: Each generation or build consumes a credit.
