Tasks, logs and your talks with the assistant, in one place.

Write down what needs doing, keep your thoughts and material, and take them to Koto-chan when you want to think something through. Next time you open it, carry on.

Jot it down

Tap the round ＋ at the bottom right of Now and write in a half-screen card that sits on the keyboard. Tasks, events and logs share the one card, and anything unfinished stays a draft.

Now

What to do today, today's events and what has been left waiting are all on this page. A thing you gave a day turns up on that day, and a thing with a reminder tells you when it is time.

Ask Koto-chan

She can see your tasks, logs and calendar. Ask her how to plan today and she lays the day out. Before she changes anything of yours she hands you a proposal, and nothing is saved until you confirm.

The same on your computer.

The web and desktop versions (Mac, Windows) use the same account and the same content. With more room, today and the next few days sit on one page, with Koto-chan beside them.

Web app in public betaThe web and iPhone apps share the same test account and data. The desktop app is still in internal testing.

Your AI tools can plug in too.

Tools like Claude Code and Codex can read your tasks and their logs through the kotolog command line and MCP, and write the result back under the task when they are done. You can see how far they got on your phone.

No public installer yetWe use it ourselves every day.

Book report, first draft

The first draft is done and saved as result.md. Section 3 still needs one example. I marked it at the end.

The same notes as Settings › About › Release notes on the phone.

0.8.2

  • Settings › About › Release notes is redone: the top says which version you are on and whether it is the latest, and below every version lists what it changed, updates over the air included.
  • When a new version is ready, a card slides down at the top with its version number: restart right away, or it tucks itself away after 10 seconds.

0.8.1

  • To add something, tap the round ＋ at the bottom right of Now: write in a half-screen card on the keyboard, drag it up for the whole page (time, reminder, subtasks, photos and files); anything unfinished stays a draft.
  • The calendar is back in the drawer, under Now; Now's week strip only picks the day, and the list follows it.

0.8.0

  • Whiteboards: Now and every Space have one. Place what you want in view and group it into areas; phone and computer share it, and Koto-chan reads it while you look at it.
  • Space page: Materials and Ask Koto-chan now sit just above the ask box.
