Ruby
Notes · Tasks · Calendar · AI

Everything you plan,
in one calm, focused app.

Ruby brings a Google-style calendar, a Trello-style board, Obsidian-style notes, and an Ask Ruby AI box together — synced to the cloud so it's waiting on every computer you sign in to.

Free · no credit card · open it in your browser or on the desktop

Four tools, one window

Switch between them with tabs — every page is a tab you can keep open.

Calendar

Week, month, and year views. Drag an event's edge to resize it in 5-minute steps, set recurring events, and sync with Google Calendar.

Tasks

A Trello-style board. Make your own columns, drag cards between them, add labels, due dates, and details with a click.

Notes

Obsidian-style folders and markdown notes with a live editor, grammar help, and math. Saved to the cloud and mirrored to your device.

Ask Ruby

An AI box wired to Claude. Ask anything and the answer streams into a brand-new tab — draft a plan, summarize notes, or turn a brain-dump into tasks.

Make it yours

Pick a design from the Market — a one-click palette for the whole app, from warm Ruby to a clean Daylight. Switch any time.
