The conversation, mapped as it happens

Oats maps the conversation in the room as it happens: topics as they turn, questions as they're asked, and whether anyone answered.

Notes after the meeting come too late. Oats shows you the conversation while you can still steer it.

Oats recording a launch review at 11:09. One line draws the conversation, with marks where an unknown, an unanswered and an answered question were asked. Below it, three topics as lanes: Pellwood launch date decision, SAML clock skew fix, and SOC 2 audit timeline, the one the room is on.

Watch the conversation take shape

Press ⇧⌘O and talk. One line draws the conversation live: a notch where the topic changes, a mark where someone asks.

Topics name themselves

Each topic gets its name from what was said. When the room comes back to one, the line goes back too.

Conversation flow at 12:33, three topics and one return to an earlier topic. The line steps down from Pellwood launch date decision to SAML clock skew fix and SOC 2 audit timeline, then goes back up to Pellwood launch date decision, where the room is now.

Every question, caught as it's asked

Each question shows up the moment it's asked, and changes when the room answers it, or doesn't. Ask again before anyone leaves.

Answered: Someone gave an answer.
Unknown: The room said it did not know.
Unanswered: The room moved on.
Open: Nobody has replied yet.

Unsure answers, checked on the spot

When an answer sounds unsure, Oats looks it up in your notes and past conversations while people are still talking.

Off by default: choose a folder of notes in Settings. Claude Code can also search GitHub, Linear, Notion and Slack, read only. When it does, the question and the reply go to Anthropic, and the search text to those services.
