ForM - Foundation Model Labs
on-device prompt lab
Free
Test prompts for Apple's on-device models without writing code. Set instructions, adjust parameters, and iterate fast.
Apple's on-device models don't come with a way to test prompts directly. ForM gives you that: a chat interface connected to Foundation Models where you can try things out before bringing them into your app.
