FAQ
FAQ
FAQ
Is this just another ChatGPT wrapper?
No. ChatGPT can't access your tabs, fill forms, or run automations. We're a full browser replacement that happens to use AI. Think Cursor, not VSCode.
Do I need to learn commands or prompts?
Zero learning curve. Just browse normally. Dafdef learns your patterns and suggests automations. The more you use it, the smarter it gets.
Is my data private?
Yes. Your browsing data stays on your device. We only process what you explicitly ask the AI to handle. No creepy tracking.
Why iPhone only?
We're mobile-native, not a desktop port. 21% of Gen Z doesn't even own a laptop. We're building for the future, not the past.
