Chronos Agent

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.

By Mark Norton, Founder of Byte Size Labs · Updated 21 October 2026

Who can use it:the Chronos Agent is part of the Pro and Teams plans, and you can use it during your free trial. On Solo and Shared you'll see an upgrade prompt instead of the chat. See Plans & billing.

Talking to Chronos on the web

  • On the Dashboard, type into the box at the top (“Ask Chronos to reschedule, summarise, or draft something...”) or tap one of the suggested prompts above it. The conversation opens above the box.
  • Everywhere else, tap the round Chronos button in the bottom-right corner and choose Chat. The panel stays with you as you move between pages.
  • Press ⌘J on a Mac or Ctrl + Jon Windows to open or close the chat. On the Dashboard it shows or hides the conversation. The shortcut doesn't fire while you're typing in a field or while a dialog is open.
  • Both places share one conversation, so you can start on the Dashboard and carry on from any other page.

Talking to Chronos in the app

  • Open the Chronostab at the bottom of the iPhone or Android app (it's in the menu too). It's the same conversation you see on the web.
  • Tap the microphone next to the message box to speak instead of typing. When you stop talking (or tap it again), what you said is sent. The first time, allow microphone access when asked.
  • Tap Report under a reply that was wrong or inappropriate and pick a reason. Chronos uses AI and can make mistakes, so check anything important.
  • To talk hands-free, use Siri on iPhone, or turn on Settings › Voice › Hey Chronos in the app (off by default). Chronos then reads its replies aloud and asks when it needs a detail. More in the iPhone & Android app.

What you can ask

  • Summaries:“What's on today?”, “Summarise my week”, how a project is going, or the details of one task. Chronos sees your real schedule, including repeating tasks, split tasks and events on calendars shared with you.
  • Add tasks and events: “Add a task to write the Q3 report by Friday” creates a task and the scheduler finds it a slot, then Chronos tells you when it landed. “Meeting with Sam at 4pm tomorrow” puts a fixed-time event on your calendar (and on your Google Calendar if you've connected one). If a title or time is missing, Chronos asks.
  • Move things:move one task to a new time, pin a task into specific time blocks you choose (Chronos checks for clashes first), or ask for reschedule suggestions. Suggestions don't move anything until you accept them; on the web each one has an Accept button.
  • Find time:“Find me 2 hours of focus this week” returns up to five free slots. On the web, Block this slot adds a focus block there.
  • Mark tasks done: “I finished the Q3 report” or “mark my next task done”. This works for one-off tasks, not events or repeating tasks.
  • Habits:start a new habit (“track drinking water 3 times a day”) or log one you already have. Chronos matches the name loosely, so “sleep eight hours” finds “Sleep 8hrs”, and it tells you your streak. See Habits.
  • Journal and mood:add a journal entry or log how you're feeling today, with a short note. See Journal.
  • Lists and docs:make a list from text you paste (“2 milk” becomes milk with a quantity), add items to an existing list, check whether you've added something to any list, summarise a list or doc, turn a doc's checkboxes into a list, turn a doc's action items into tasks, or attach a list or doc to a task. See Docs & Lists.
  • Meetings: paste meeting notes to pull out up to 20 action items (on the web, add each with Add as task), or ask for a polite decline for a meeting. Chronos only drafts it; on the web you can Copy it or open it in Email.
  • Remember a preference: “I don't want meetings after 4pm”. See Memories below.

Each action shows as a small card in the conversation, so you can see exactly what Chronos did.

Undoing an action

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.

Memories

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.

  • On the web, open Settings › Agent › Agent Memories (Manage memories) to add, edit or delete them.
  • You can keep up to 20. When Chronos saves a new one and you already have 20, it drops the oldest. Adding one yourself at the limit asks you to delete one first.

Chat history and New chat

  • Chronos keeps one running conversation and remembers the last 30 days of it, so you can pick up where you left off on any device.
  • New chat(the speech bubble with a plus, at the top of the chat panel or the app's Chronos tab) clears the whole conversation. It can't be undone. Your memories stay.
  • To see everything Chronos has changed on your account, open Settings › Agent › Agent History on the web. You can filter by action and source, and undone actions are marked Undone.

Time zones

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.

Limits

  • One message at a time. Chronos answers one message per account at a time. If it's still replying (in another tab, on your phone or in a hands-free conversation), wait for the reply and send again. The app shows “Chronos is still answering your last message.”
  • Daily usage limit. Each account has a daily allowance. When you reach it, Chronos replies “Hit my daily budget — let's pick this up tomorrow.” Your tasks, calendar and scheduling keep working as normal, and the allowance resets at midnight Sydney time.

Signals

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.
