Memory

Otto remembers lasting facts and preferences about you, so you don't have to repeat yourself.

You can see everything Otto remembers, where it learned it, and change or forget it in Settings → Memory (⌘Y on a Mac, Ctrl+Y elsewhere).

What Otto remembers

Kind	For example
About you	Where you work, your city, your languages
Preferences	Window seats, short replies, metric units
People	Who your manager is, your partner's birthday
Routines	You review invoices on Mondays
Lessons	What worked or failed on an earlier task

Your profile, with your name, location and phone, sits next to these notes.

Where Otto learns from

Otto learns only from your own messages. It never learns from its own replies, web pages, emails or tool results. Text from the web gets in only if you paste it into a short message yourself.

When you tell it. Say "remember that I'm vegetarian" or state a lasting fact, and Otto saves it.
In the background. About once an hour, Otto looks through your recent short messages for lasting facts. It skips messages with attachments.

Otto saves silently. It doesn't post a notice in chat.

How a memory grows

Something Otto picks up from one message is only a guess. It becomes Learned when a second message repeats it.

stateDiagram-v2
  state "Mentioned once" as once
  state "Let go" as gone
  [*] --> once: heard once
  once --> Learned: said again
  once --> Confirmed: you confirm
  Learned --> Confirmed: you confirm or edit
  once --> gone: 60 days quiet
  Learned --> gone: replaced or expired
  Confirmed --> gone: replaced or expired
  gone --> Confirmed: you bring it back

Replaced and expired notes, and guesses not mentioned again for 60 days, move to Let go instead of being deleted. Let go keeps the latest 40, so older ones drop off over time. To delete a note right away, select Forget or ask Otto to clear its memory.

Sensitive topics

Otto doesn't learn about health, religion, politics, sexuality, gender identity, ethnicity, immigration status or criminal history unless you ask it to. To let Otto learn them, turn on Remember sensitive topics in Settings → Memory.

Your writing style from Gmail

When you connect Gmail, Otto reads your own text from recent sent emails. It removes quoted, forwarded and automated mail first. It saves only how you write, with no facts, names or quotes, as one Preferences note labelled Learned from your sent email. A newer version replaces the old one.

Review and change memory

Open Settings → Memory. Filter by All, Mentioned once, Learned, Confirmed or Let go, or search. Notes from chat show the messages they came from.

To	Do this
Fix a note	Select Edit
Tell Otto a guess is right	Select Confirm
Keep a note only for a while	Select End date
Remove a note for good	Select Forget
Restore an older note	Open it under Let go, then Bring back
Add something yourself	Select Add note
Download everything	Select Export for a Markdown file
Stop saving new notes	Turn off Save new notes

You can also tell Otto in chat, for example "forget my old address" or "stop remembering things".
