Sceneuron: signs of intelligence for your camera.

An AI producer that puts live signs on your video in Zoom, Meet, Teams or any stream. Professional doesn't mean sterile.

Watch the demo Read the Devpost

Alex on a video call with a Sceneuron sign on his video that reads “We're off track”, next to his name label.

Four ways to raise a sign

Signal without taking the floor, or breaking eye contact.

Stream Deck

One key per sign. It lights up while the sign is on.
Hands

3 fingers is a 3. Raise your hand to ask.
Voice

“Sceneuron, wrap it up.”
AI

Hold something up and it names it.

Stream Deck

A key for every sign.

Our own Stream Deck plugin. Each key looks like the card it raises and turns amber while that card is on your video.

Live description

It narrates what it sees.

A live line of what the camera understands. On your Mac, every frame, free.

On-device
Free
Nothing sent

Cheap intelligence first. The big model only when it matters.

1
On-device vision
Every frame, free. Faces, hands, 21 joints, objects, text.
2
Quick judge: Jev
TypeSafe's Jev judges your conditions from on-device facts in under a second, only when the scene changes. Text only, never images.
3
Gemini
Only when unsure, or when something needs a name.

Tell it what to watch for

Write it in plain English: “I'm holding something up.” “A pet walked in.” It shows “Now showing: coffee mug” or “Cat on stream!”

Set up with AI

“I run sprint planning on Zoom.” Gemini proposes the decks, cards and rules. Nothing changes until you say yes.

Say anything

If Sceneuron doesn't know a voice command, Gemini figures out what you meant.

Every decision explained

Each change lands in a log with the AI's reason, how long it took and what it cost. An hourly budget caps the spend.

Talk to it.

Push to talk, or just say its name.

It only acts on a clear match. “I don't agree” won't raise Agree.
Cards can speak out loud in the call.
Card names are sent as keyterms, so it hears them right.

“wrap it up”
“my vote is eight”
“reveal”
“next round”
“hacker theme”
“subtitles in Spanish”
“mind blown”

Make those long sprint planning meetings fun and engaging.

Everyone votes in secret, so nobody just copies the loudest person. SpacetimeDB keeps every vote hidden until someone hits reveal, then all the cards flip at the same moment.
