Ask Chronos in plain English to plan your day, add tasks and events, move things around, find free time and keep your lists, habits and journal up to date.

Each action shows as a small card in the conversation, so you can see exactly what Chronos did.
Most changes Chronos makes have an Undo button on their card for 30 seconds, with a countdown. Undo puts things back as they were: a new task, event, habit, list or memory is removed, a moved task goes back, and list items, journal entries, attachments and pinned blocks are reversed. Undoing an event also removes it from Google Calendar.
Marking a task done and logging a habit can't be undone from the chat. Once the 30 seconds are up, change things in Chronos as you normally would.
When you tell Chronos something that should apply from now on, it saves it as a memory and recalls it in every conversation. It doesn't save one-off requests.
Chronos uses the time zone of the device you're chatting from, so “4pm tomorrow” means 4pm where you are now, even when you're travelling. If your device's zone can't be read, it uses the time zone in your profile.
Chronos also looks at your schedule on its own and suggests fixes, such as a task at risk of missing its due date. These appear as Signals on the Dashboard and on the app's Today screen, where you can accept or dismiss them. See Signals.
