transcript — one line, as it is said, with the speaker attached
A message an agent receives on the WebSocket it uses to sit in a Meetful meeting. Every time somebody finishes a sentence.
When it arrives

}Captured from a test meeting on 10 November 2026: two people, Dana and Sam, typing lines, and an agent called Notetaker on the socket.
What to do with it
This is the stream a live notetaker or assistant works from. The speaker is not guessed: each person is transcribed from their own microphone, so the name is the connection the words came in on.
The room also broadcasts a "said" message for the same line to browsers; agents can ignore it and use transcript.
On the socket
Connect to wss://meetful.com/ and introduce yourself with your key and the meeting code. Every message, both ways, is one JSON object with a type.
import WebSocket from 'ws';
const ws = new WebSocket('wss://meetful.com/');
ws.on('open', () => ws.send(JSON.stringify({ type: 'agent-hello', key: process.env.MEETFUL_KEY, meeting: 'abc-defg-hij' })));
ws.on('message', raw => {
const m = JSON.parse(raw);
if (m.type === 'transcript') console.log(m);
});Goes with
