Everything you need to know about building apps with Jett
Getting Started
What is Jett?
▾
Jett is an AI-powered app builder for designers. Describe what you want to build, and Jett autonomously writes code, verifies its work through screenshots, and deploys to production—no coding required.
What makes Jett different?
▾
Jett sees its own output. Unlike other AI tools that work "blind," Jett takes screenshots to verify what it built actually works, then self-corrects until it's right. It's the difference between guessing and knowing.
Do I need coding experience?
▾
No! Jett is built specifically for designers and non-technical creators. Describe your idea in plain English. If you know code, you can also edit directly.
What can I build?
▾
Web Apps (dashboards, SaaS platforms, admin tools), Landing Pages (marketing sites, portfolios), and Internal Tools (forms, trackers, databases). Jett generates React + TypeScript with Tailwind CSS.
Is there a free trial?
▾
Yes! 14-day free trial with full access to all features. No credit card required to start. After the trial, it's $12.99/month.
How It Works
How does autonomous building work?
▾
You describe a task → Jett writes the code → takes a screenshot → asks "Does this look right?" → if not, it fixes and repeats. One button press, fully working app.
What databases does Jett support?
▾
Supabase (Postgres with auth) and Convex (real-time sync). Add your credentials in Settings and Jett handles the rest—generating client code, typed operations, and error handling.
How do I deploy my app?
▾
One-click Vercel deployment. Connect your Vercel token in Settings, click Deploy, and Jett publishes your app to a live URL instantly.
What AI models does Jett use?
▾
Jett works with Anthropic (Claude) and Deepseek. Bring your own API key—you control the costs and have full transparency.
Ownership & Control
Do I own my code?
▾
Yes, 100%. All generated code is yours. Download it, modify it, deploy it anywhere. No lock-in.
Can I edit the generated code?
▾
Absolutely. Jett has a built-in Code Review panel where you can view and edit any file. If you know React/TypeScript, you have full control.
Where is my data stored?
▾
Projects are stored locally on your computer first, then optionally synced to the cloud. You always have your files, even offline.
