Have a question, found a bug, or need help with your subscription?
We’ll get back to you within 1–2 business days.
You write your work on the canvas with your Apple Pencil. The app sends a snapshot of your work (and the problem, if you provided one) to an AI model, which responds with guiding questions — never direct answers.
The app supports OpenAI (GPT-4o), Anthropic (Claude), Google Gemini, and Ollama for local AI. Free plan users get a limited number of managed Gemini hints per day. Subscribers get unlimited access.
Open the app, go to Settings (gear icon), then tap Restore Purchases. Make sure you’re signed into the same Apple ID used when you subscribed.
Subscriptions are managed by Apple. Go to Settings → Apple ID → Subscriptions on your iPhone or iPad and cancel from there.
Canvas snapshots are sent to the AI provider to generate hints, but they are not stored by us. See our Privacy Policy for full details.
Double-check that the key is valid and has sufficient quota on your provider’s dashboard. API keys are stored in the iOS Keychain on your device and never leave it.
