An assistant that asks before it acts.
The assistant makes suggestions – nothing is saved until you confirm. You decide which data it may see.
- ✓You grant permissions one by one: events, tasks, projects, contacts.
- ✓Notes are never sent to the AI.
- ✓Suggestions open in the form – you review and save.
- ✓The calendar works just the same without AI.
