Watermelon makes AI sticky notes you can talk to, on iPhone, iPad and Mac. Say what is on your mind; AI turns it into tasks, checklists and reference notes on a board that feels like real paper. When plans change, hold a task, say the change, then review and apply it.

The feel of paper. The power to do more.

A sticky note gives a thought somewhere to live. Watermelon keeps that familiar feeling: soft paper textures, gently curled edges and space between the things that matter. A red pin marks the selected project or list, so you know where your next thought will land.

A little help from AI

Capture naturally. Speak or type. AI separates things to do from information to keep, preserving useful details.
Give thoughts a home. Inbox catches anything. Lists thread one kind of work. Projects group related lists.
See the small steps. Track tasks with checklists, counts, percentages and stages.
Change it in a sentence. Edit tasks by voice when plans change.
Map. Explore the connections between projects, lists and tasks. Zoom out for context and in for detail.
Diary. Write or speak an entry, add photos, and browse your words alongside task activity by date.

Your thoughts belong to you
