Sitin
For teams that work with Claude and ChatGPT

Save a seat for your AI.

Your agents do the work, but they never hear the meeting. Sitin gives them a seat in the call you are already in. They hear what is decided, answer when you ask them, and start the work before you hang up.

Why this exists

Notes are written for people.People aren’t the ones doing the work anymore.

Every meeting tool got better at notes. Then you open Claude and repeat the whole meeting. The one doing the work was never in the meeting.

It didn’t hear it

The decision was made out loud. Your agent only gets a retelling.

You carry the message

Five people explain it to five AIs. Now there are five versions of what was agreed.

You find out too late

Leave out half a sentence, and an agent does the wrong thing, quickly and carefully.

One meeting, held twice

The same Tuesday call.
One week apart.

Priya’s team of six builds an API gateway. Their largest client renews its contract this month. Daniel, the client’s technical lead, has his budget meeting on Friday.

Last Tuesday

A clear meeting. A messy week.

  1. In the meeting · Daniel

    “Raise the rate limit for paid tenants from 300 to 600 a minute.”

  2. After the call · Priya’s note to Tomás

    “The client wants the limit raised to 600. Please look at it after your flight.”

    “Paid tenants” was left out.
  3. Wednesday · Tomás to his Codex

    “Change the rate limit to 600.”

  4. Wednesday night · Codex’s pull request

    Global rate limit 300 → 600

    The free tier was raised too.

Thursday: the change is reverted and redone. The next Monday: the quote is finally sent. Daniel: “The budget meeting was last Friday.”

This Tuesday

This time, the agents sat in.

  1. In the meeting · Daniel

    “Raise the rate limit for paid tenants from 300 to 600 a minute.”

    Tomás’s Codex heard it directly.
  2. 10:14 · Priya, speaking

    “That’s settled. Paid tier to 600, pull request by Thursday. Tomás’s Codex takes it.”

  3. 11:15 · Waiting in Priya’s inbox

    A pull request that changes the paid tier only, a draft quote, and a follow-up email to Daniel.

  4. Wednesday 07:20 · Tomás is back online

    Nothing to catch up on. One pull request to review, with Daniel’s exact words attached.

Friday: Daniel brings the plan and the quote to his budget meeting. The renewal is approved.

How it works

Done by the time you hang up.

Three things to learn. All of them are things you say.

  1. 01

    Bring them with you

    Open the meeting link as usual and choose which agents join. One extra participant joins: a round table with everyone’s agents. The other side installs nothing.

  2. 02

    Ask them by name

    Ask a question aloud. The agent answers in the call. It uses its owner’s files, code and connected tools, and it shows where the answer came from.

  3. 03

    Say “that’s settled”

    Say what was agreed and who takes it. That sentence is the instruction. Drafts wait in your inbox, each linked to the words it came from.

What’s different

Others gave the meeting an AI.
Sitin gives your AI a seat.

Use cases

Not only for people who write code.

If an AI does part of your job, it belongs in your meetings.

In the meeting

“Claude, what did people say about export in last week’s interviews?”

Maya’s Claude: Seven of nine asked for scheduled exports. Nobody asked for more file formats.

interviews/2026-11/ · 9 notes

When you hang up

Product spec: Scheduled exportsMaya’s Claude · document, attached to the issue
Waiting for your OK
  • Problem: teams rebuild the same export by hand every week
  • Scope: daily and weekly schedules, CSV only
  • Out of scope: new file formats (0 of 9 interviews)
Settled at 14:22: “Scheduled exports first. Formats can wait.”

Privacy

What’s yours stays with you.

  • Audio never reaches us

    Sitin joins from your computer. Meeting audio is handled there, by the models you choose. It doesn’t pass through our servers.

  • Our servers run no AI

    They store text and keep your team up to date. Every model call happens on a teammate’s own machine.

  • Your subscription, your keys

    Agents run on the Claude or ChatGPT plan you already have. Keys stay on your computer. We add no fee on top.

  • Nothing is sent without you

    Agents draft, people approve. Code arrives as a pull request and never goes directly to the main branch.

FAQ

Before you bring an agent to a client call.

What does the other side see?

One extra participant called Sitin Agents. Its video is a round table that shows which agent belongs to whom, and it posts a line in chat saying agents are present and the call is being transcribed. They install nothing. If the host mutes that participant, all agents are muted.

Which meetings does it work in?

Zoom is in early access. Google Meet and Microsoft Teams come next. Sitin also has its own meetings, where agents can do more: show cards, work on documents and whiteboards alongside you.

Which AI do I need?

A Claude or ChatGPT subscription that includes Claude Code or Codex. The desktop app finds them on your computer and connects them. You do not need an API key.

Where does the meeting audio go?

It stays on the computer that joined. Speech is turned into text there, with the model you pick: one that runs locally, or your own provider. Sitin’s servers receive text only (the transcript, what was settled, the results), and they never call an AI model.

Can an agent act without asking me?

No. Agents answer and draft. Anything they produce waits for a person: documents and emails in your inbox, code as a pull request. Said the wrong thing? Say “undo”.

What does it cost?

Nothing during early access. When paid plans start, we’ll charge per person. Agents are free and unlimited. You keep paying your AI provider directly. See pricing.

Does it run on Windows or Linux?

The desktop app is available for macOS first. Windows is next. Until then you can use Sitin in a browser and connect a computer with the command-line client. See download.

The Tuesday after that, before the call starts, Daniel types one line in the chat:Can my Claude have a seat at your round table?

Let your agents sit in.
