Aura started as a note-taking app and grew into a full productivity system: rich notes, tasks, focus sessions, and habit tracking, synced in real time across web and native mobile builds.
It is also where I test how an AI agent should behave inside a tool you trust with your plans. The answer I landed on: it proposes, you approve.
An agent with a confirmation step
Aura's agent reads your notes and tasks and drafts actions: reschedule this, break that into subtasks, file this note. Every write it wants to make renders as a preview card you accept or dismiss. Nothing mutates without explicit confirmation.
Designing the preview-and-confirm pattern meant the agent could be genuinely useful without the anxiety of an autonomous system editing your data in the background.

- 03User accepts or dismisses
- 04Accepted changes sync to every device
Real-time everywhere, including a home-screen widget
Collaboration runs on a conflict-free sync layer built with Yjs and SpacetimeDB, so two people can edit the same note without stepping on each other. The same data layer feeds Android home-screen widgets with the day's tasks and quick add.
The editor is built on TipTap: task lists, tables, inline formatting, images, and links, designed to stay readable at phone width.
