A reminder app that calls your phone instead of sending a notification
At the chosen time Jules places an automated voice call from a regular phone number that states which reminder is due, so it is much harder to dismiss than a push notification.
Schedule one-off, weekly, monthly, daily or custom-day reminders and choose how early the call arrives — from five to 45 minutes before the due time — plus up to three retry calls if you miss the first.
Connect up to five Google accounts and Todoist, or message Jules on Telegram, and reminders populate themselves so you do not have to open the website each time.
Everything is set up in a web browser; you simply verify the phone number you want Jules to call and start adding reminders.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
