Taskbook Sign in Get started
A task manager with an assistant that plans

Tell it everything. Get back a planned week.

Type or say what’s on your plate, however it comes out. Assist asks about anything it would otherwise guess, turns the rest into tasks and fits them into your week. Every change has Undo.

Taskbook’s calendar with Assist open. A brain dump about a presentation, a report and two errands is typed in; Assist asks how long the slides will take and when the practice run should be, makes five tasks and a project, and Auto time-block fits them into the week around meetings.

01Assist

Help with the hard parts, from Gemini.

Assist runs on Google Gemini. Ask in your own words, or type / to pick a command. Here it breaks a big task into steps you can start today.

02Undo

You’re always in control.

Assist shows every change as a card with its own Undo, even after other edits. Deletions and big batches wait for your OK.

03Quick add

Type it the way you’d say it.

Write it like a note to yourself. The date, time, length, project, labels and priority are picked out as you type.

04List

Clear out your day, one tick at a time.

Group tasks by section, see how the project is tracking at the top, and tick things off as you go. Changed your mind? Every completion has Undo.

05Board

Move work along as it happens.

Each section is a column. Drag a card into In progress when you start it, and the column totals update as you go.

06Calendar

Give every task a time.

Drag a task to the slot you want, then pull the bottom edge to make it longer, or press Auto time-block and let Assist place them all. Each day shows how full it is, and meetings from Google Calendar appear as Busy.

Both are optional. Connect them in Settings whenever you’re ready.

Questions

How do I get started?
Create an account with Google or an email link. There are no passwords to remember.
What powers Assist?
Google Gemini. Ask in your own words, or type / to pick a command like break down, review or time-block. You can use your own Claude or Gemini key instead, or switch to On-device, where the / commands still work and nothing leaves your browser.
Will Assist change things without asking?
Small changes apply right away, and each one has its own Undo. Deletions, anything from an attached file, and batches of more than ten changes wait for you to approve them.
Where is my data?
In your browser, with a copy in your account so your devices agree. Only you can read your tasks, and there’s no analytics or ad tracking.
What does Taskbook see of my calendar?
Only when you’re busy or free. Never event titles, guests or locations.
Can I take my tasks with me?
Yes. Settings → Data → Download JSON saves your tasks, projects, labels, filters and settings as a file you can import again.
Is there a mobile app?
Not yet. Taskbook works in your phone’s browser: the sidebar becomes a drawer and panels open full screen.
