Before you build
Do I need to write code?
Your AI assistant can write it. Give it the documentation and your idea, then paste the finished file into Gem.
What uses my plan?
Each model or web search call uses one message from the plan of the person using the app. Storage and leaderboards are free.
Can I change my app?
Yes. Choose Edit from your app list and send replacement code. The link stays the same.
What are the limits?
One file, up to 4,000 characters. No imports or direct network access. Payments, file uploads and scheduled jobs are not available yet.
