Write the day down, and read it back.

MyBook is a local-first personal notebook built around one page per day: text, photos, voice and video go straight in, the day’s plans live on the same page, and an evening review closes it. A calendar, insights and full-text search bring any past day back — and everything stays on your own computer.

Positioning

For people who keep a real journal and review it, and for anyone who wants an AI agent to do the writing and planning with them.

Capabilities

MyBook

One page per day: a time spine threading the day’s entries, finished plans and review together.

Capture anything: text, a photo, a voice note, a video or a dropped file — all one kind of entry.

Plans: one line sets priority, due date, tags and a repeat rule; unfinished ones roll over to today.

Review: daily and weekly, where “three things for tomorrow” become tomorrow’s plans.

Look back: a calendar with lunar dates and holidays, plus streaks, a mood curve and a year heatmap.

25 MCP tools so Claude Code, Cursor and other agents can write, plan, review and search for you.
