Questions & answers

What is Jisapp?
Jisapp lets you paste HTML code generated by an AI into the Studio, run it as a web app, and publish it. The official site is https://jisapp.app/en.
Can I use it if I've never programmed?
Yes. An AI like ChatGPT, Claude or Gemini writes the code — on Jisapp, you mostly just copy and paste it.
How much does it cost?
Making and publishing apps on Jisapp is free. The AI service you use to generate code follows its own free tier and pricing. Some apps in the market may be set as paid by their creators.
Do I need to sign up?
You can try the Studio without an account. We recommend signing in if you want to keep your apps, publish them, or use your data on other devices.
Do I need a server or database?
No. Apps run in the browser, and they can save data with window.Jisapp.saveData / loadData, which Jisapp provides.
Which AIs can I use?
Any AI that can output HTML — ChatGPT, Claude, Gemini and more. Paste the generated code into the Jisapp Studio to run it.
How do I publish my app?
Check the preview in the Studio, then publish to get a URL. Share it on social media or in messages. You can also list it in the market on the home page.
Where is my saved data stored?
For apps in your library while signed in, data is saved on Jisapp and can be loaded from other devices. When you're not signed in, it stays in your browser on that device.
Can I use apps other people made?
Yes. Browse published apps from the home page or search. Free apps open right away.
What is window.Jisapp?
A small JavaScript toolkit Jisapp provides inside every app, used to save and load data and to call external APIs. The older name window.Zisup still works too.
Is Jisapp available in Japanese?
Yes. Jisapp started in Japan — use the language button (English / 日本語) to switch to the Japanese site.
