Describe what you need. Watch AI build you a real app — with its own database, widgets, and AI assistant built in.
Figure out deployment. Set up a database. Find hosting. Wire up authentication.
Ctrl is different.
It's a complete environment where AI builds apps that just work — instantly running in your browser, with storage, widgets, and AI assistant built in. No download required.
Features
From idea to working app in minutes. No setup, no configuration, no deployment.
Describe what you need in plain language. AI designs the database, writes the code, and delivers a fully functional React application. No templates. No drag-and-drop builders. Real code that AI understands completely — so it can evolve your app through conversation.
Press ⌘J and the AI sidebar opens. But here's what's different — the AI has direct access to your app's database. Ask it to create records. Analyze your data. Make suggestions. You approve changes with one click, and they're saved instantly.
Open any document. Ask AI to improve it. See precise diffs right in your content — accept or reject each change individually. The AI edits your actual data, not a copy. You stay in control.
Every app gets its own database. Fast and reliable. Your data syncs across devices and is always available. No vendor lock-in — export anytime. You own everything you build.
Every app can have a widget on your desktop. See live data without opening full apps — today's tasks, habit streaks, stock prices, weather. Customizable, responsive, always up to date.
Apps are real code files you can read, modify, and export. Take your code anywhere. You're never locked in. Export as .ctrlapp packages to share or backup.
Our vision: one unified personal data layer. Query your projects and invoices together. Connect your habits to your goals. What takes Zapier integrations elsewhere is one SQL statement in Ctrl — because AI built all your apps.

How It Works
Tell Ctrl what you want in plain language. Upload a spreadsheet, explain a workflow, or just describe an idea.
AI designs the database schema and writes a complete application. Watch the code generate in real-time.
Your app is ready instantly. Add data, customize the UI, or ask AI to enhance it further. Works in any browser.
Apps grow through conversation. "Add a calendar view." "Export to PDF." AI understands your app completely.
