Getting Started
What video formats does Replay support?
Replay supports MP4, WebM, and MOV video formats. For best results, use 1080p or higher resolution recordings.
How long can my video be?
We recommend videos between 5-60 seconds. Longer videos (up to 2 minutes) are supported but may take longer to process and use more credits.
What makes a good recording?
Record in high resolution, move slowly through the UI, show all navigation states, and hover over interactive elements. Avoid fast scrolling or quick movements.
Can I record mobile UIs?
Yes! Record your phone screen or use a device emulator. The AI will detect and replicate responsive designs.
AI & Code Generation
What technology does the generated code use?
Generated code uses HTML5, Tailwind CSS, and Alpine.js. It's production-ready and works as a single HTML file with CDN dependencies.
Is the generated code pixel-perfect?
The AI interprets your video to create functional UI - it's not a pixel-perfect copy. Use Edit with AI to refine any differences.
Can I use React/Vue/other frameworks?
Currently, Replay generates vanilla HTML/Tailwind/Alpine.js code. You can easily convert this to component-based frameworks.
Does the AI hallucinate content?
The AI faithfully reconstructs what it sees in your video. If you connect Supabase, it uses real table names and data structure.
Database Integration
Which databases are supported?
Currently, we support Supabase. More database integrations (Firebase, PlanetScale) are coming soon.
Can Replay modify my database?
No. Replay only reads your database schema and sample data. It never writes, modifies, or deletes anything.
Are my database credentials safe?
Yes. Your Supabase URL and anon key are stored in your browser's localStorage - never sent to our servers.
Why do my tables show 0 rows?
This usually means Row Level Security (RLS) is blocking access. Create a SELECT policy for the anon role on tables you want to expose.
Pricing & Credits
What costs credits?
Video to UI generation costs ~150 credits. Edit with AI costs ~10 credits per edit.
Do my credits roll over?
Monthly subscription credits reset each billing cycle. Top-up credits never expire and stack with subscription credits.
What happens if I run out of credits?
You can purchase top-up packs anytime or upgrade your subscription. Your existing projects remain accessible.
Can I get a refund?
We offer refunds within 7 days if you haven't used your credits. Contact support@replay.build for assistance.
Publishing & Export
Where are published sites hosted?
Published sites are hosted on our infrastructure at [your-id].replay.build. They include HTTPS by default.
Can I use my own domain?
Custom domains are available on the Agency plan. Contact us for setup instructions.
Can I export and host elsewhere?
Yes! Download the HTML file and host it on any static hosting service like Vercel, Netlify, or GitHub Pages.
Are there usage limits on published sites?
Published sites have generous bandwidth limits. High-traffic sites may need custom arrangements.
Privacy & Security
Do you store my videos?
Videos are processed in memory and not permanently stored. Generated code is stored in your browser's localStorage.
Is my data used to train AI?
No. Your videos and generated code are never used to train our AI models.
Who can see my published sites?
Published sites are public by default. For private sharing, use the code download feature instead.
How do I delete my account?
Go to Settings → Account and click 'Delete Account'. All your data will be permanently removed within 30 days.
