AI app builder
Describe a calculator, a planner or a game. askROI builds it as an app inside the chat.
Nothing sends until you start, and you can change anything afterwards.
Export formats
- PDF (.pdf) Opens anywhere and prints as laid out.
An interactive page or chart that opens from the chat and downloads as a PDF. Every export also lands in your Library as an artifact you can revise, share with a link, and pick up again in another chat.
How it works
- Describe what the app should do: every input, control, calculation, and result you want to see.
- askROI's Mini apps tool builds it as a small app with its own components and shared state, checks that every feature you asked for is there, tests that it renders, and opens it in the chat.
- Use it right away, download a PDF snapshot, or keep chatting to add a feature or change the design, and askROI rebuilds it.
What people use it for
- Calculators bill splitters, loan and pricing comparisons, and unit converters with the exact inputs you need.
- Planners seating charts, schedules, and simple boards with several views.
- Timers and trackers for a session workout timers, scoreboards, and counters you use while the app is open.
- Custom tools ask for a saved set of instructions askROI follows on future requests.
- Prototypes try out an idea for a tool before anyone builds it for real.
Questions
What can a mini app do?
It can have several screens or panels, forms and buttons, calculations, and state shared between its parts, laid out to work on a phone as well as a larger screen. It can also include images you upload or generate in the chat, and it can send a follow-up request back to the chat or open an outside link.
Does it save my data?
No. A mini app keeps its data in memory only while it is open, with no browser storage or cookies, so reopening it starts fresh. Use it for work you finish in one sitting, such as a calculation or a planning session.
Can it fetch live data from the web?
No. Mini apps run sandboxed with no network requests, so they cannot load prices, weather, or data from your accounts. Put the data it needs in your request, or ask askROI to include it when building.
Can I change the app after it is built?
Yes. Keep chatting and describe the change. askROI rebuilds the app from its saved project, so later edits start from the version you already have.
Can askROI make a reusable tool instead of an app?
Yes. Ask in any chat for a custom tool: a saved set of instructions, plus any scripts or reference files it needs, that askROI follows on your future requests, such as a house style for reports or a fixed review checklist. It has no screen of its own, and you manage it in Settings under Custom tools.
What does it not do?
It does not make a website you can host, a store app you can install, or an app several people use together with shared data. The download is a PDF snapshot of the app, not a working copy.
