Coaster
Not built yet. Finding out who needs it.

Agree out loud what AI gets to remember.

Put it on the table. If everyone taps, everyone's AI may remember this conversation. If anyone doesn't, it stays off the record.

Tell us how you'd use it

Try it: everyone at this table has to tap.

One way to use it

What it does

Tap

Any iPhone touches the coaster. There's nothing to install: a small part of the app opens by itself.

Agree

Each person confirms what's allowed, for this conversation only. One holdout means no AI notes for anyone.

Keep the receipt

Everyone's phone holds the same signed record of who agreed, when, and to what. Pick up the coaster and it ends.

No coaster with you? One phone opens a room and the others scan to join. Same agreement, same receipt.

Why this, why now

These are public events and rules, not our customers. We don't have customers yet. The lawsuits below are allegations that no court has decided, as far as we could find.

The notetaker that joined anyway

A 2025 class action says Otter's meeting bot recorded people who never agreed. Otter says its users are responsible for getting permission. That leaves the person across the table with no way to answer.

The glasses in the room

A 2026 suit followed reports that contractors reviewed footage from Meta's AI glasses, including private moments. Meta says it filters that data first. Everyone nearby is still left guessing what's being captured.

Lawyers now have to ask, each time

A New York City Bar ethics opinion says lawyers should tell clients and get consent before AI records their calls, on every call unless the platform clearly shows it's recording.

Some places already require everyone's yes

The Reporters Committee counts about 11 US states that mainly require all parties to agree to a recording. The rules vary by state and by situation.

Three scenes it could fit

Made up to show the idea. These are not real customers or results.

The first therapy session

A client taps to allow AI notes, or leaves the coaster alone. The choice is theirs, made in the room, and it's on record either way.

The dinner with the pendant

One friend wears an AI recorder. The coaster stays untouched, so it's clear to everyone that tonight isn't being kept.

The in-person customer meeting

Four people, one table. Everyone taps, and each person's AI can keep notes from the same agreed meeting. Nobody had to raise it awkwardly.

What it can't do

  • It can't stop someone hiding a recorder. It makes the agreement visible, and gives AI tools that cooperate a rule to follow.
  • Other AI tools would have to choose to respect it. Until they do, it's a clear social signal and a record.
  • It isn't legal advice, and a tap may not satisfy the rules for your profession or where you live.

What would you use this for?

That's the question we're trying to answer. A table, a room, a job, a family: tell us what you picture. We read every answer, and the people with the clearest need get the first ones.
