Where Groupthink's Memory Comes From

Groupthink remembers the people in your life from a set of sources. Some run on their own once you connect them. Some only run when you hand Groupthink something. A few are off until you turn them on. This page lists all of them in one place, with a link to each source's own page for the details.

Everything Groupthink keeps about a person is private to you, and each fact names where it came from.

How to read the tables

• Starts says whether a source runs on its own once it is connected, or only when you do something.
• Counts as says which date on the person it moves. Groupthink keeps two: Last meeting (a live conversation, in person, on a call, or on video) and Last contact (anything asynchronous, such as a text or an email). Both appear as columns in your people list, and either one keeps someone off the Going Cold list. "Nothing" means the source adds to what you know about the person without moving either date.

Sources that run on their own

Source	What it reads	Starts	Counts as
Google Calendar and Outlook Calendar	Your events and who was invited, including past events: 12 months back on Free, up to 3 years during your trial or on Pro	On once connected	Last meeting, once the meeting is recorded or you confirm it happened. Until then the people list shows it as an On calendar date
Personal events without invites (details)	A person's name in the title of an event you created with no attendees, such as "Dinner with Ines"	Suggested, you confirm	Last meeting, once you also confirm it happened
The notetaker on Zoom, Google Meet and Microsoft Teams	What was said in the calls it records, and who said it	Off until you turn on auto-join, or add it to a meeting. Trial or paid plans	Last meeting
Linked People	Who was invited to a meeting and who joined the call link	On	Last meeting
Booking links	The name, email and note of someone who books time with you	On once you share a booking link	Last meeting, once the meeting is recorded or you confirm it happened
Facts from the web	Public web pages about someone you are meeting for the first time, each with a link to its source	Paused for now. Trial or paid plans when they return	Nothing
Mac Messages	The text conversations you choose to import, then new messages in those conversations	Off until you import. Syncing new messages is on once you do	Last contact
GitHub activity	Pull requests you and someone else both worked on, and reviews either of you gave the other	Off until you turn it on in Settings	Last contact

Sources you hand to Groupthink

Source	What it reads	Starts	Counts as
Quick log	One sentence you type, such as "coffee with Theo, he is moving to Lisbon"	When you use it	Last meeting, or Last contact when your words describe a text, email, Slack message or gift
Log an interaction	A date, how it happened, and your notes, for one person	When you use it	Depends on how it happened: in person or phone is Last meeting; text, email, gift or other is Last contact
Photos, PDFs and notes	A file or note you upload and file to a person	When you use it	Nothing, unless it carries a date
Pasted text threads	One text conversation you paste in, matched to people by phone number	When you use it	Last contact, if it carries a date
Slack threads	A Slack thread you paste in	When you use it	Last contact
Forwarded meeting notes	Recaps from Granola, Gemini, Otter, Fireflies and Zoom AI that you forward by email	When you forward one, or automatically with a Gmail filter	Last meeting, once the recap is filed to the people in it
Speaker names	Which contact a voice in a transcript belongs to	You confirm. One-on-ones get a suggested name	Nothing on its own
AI assistants	Notes, captures and logged interactions your assistant writes for you, such as Claude	When you ask your assistant	Depends on what the assistant saves: a logged interaction follows how it happened

Turning a source off

Each source's own page explains how to disconnect it or turn it off. Turning a source off stops new information from coming in. Notes, facts and recorded meetings it already added stay on the person, but disconnecting a calendar removes its events from Groupthink. You can export everything at any time.
