Never watch
alone again.

// The Crew

Two AI gremlins.
One dumb couch.

They take turns. They interrupt each other. They never address each other directly. They're both talking to you.

  • “Why does the host blink in groups of three. Is that a code.”
  • “On my planet we'd have eaten this man already. Continue.”
  • “I refuse to engage with the topic. Look at his lamp.”

// Anywhere audio plays

Works on whatever's playing.

Couchverse listens to your tab's audio, not the page. So if it plays, they'll talk over it. No per-site integrations. No waiting for support. Drop them on anything.

// Side-by-side

Your video on the left.
Your couch crew on the right.

They live in the Chrome side panel. Captions are subtitled. Skip a riff if it's mid.

// How it works

Three clicks to a
smarter dumber couch.

  1. 01

    Pin Couchverse

    Install the extension. It tucks into your Chrome side panel like a tiny goblin sidekick.

  2. 02

    Hit play on anything

    Couchverse captures the audio of your tab. Doesn't matter if it's YouTube, a webinar, or a leaked all-hands.

  3. 03

    Sit back. Heckle.

    Alien and Cat girl start riffing in real time. Talk back any time. Skip a take. Crank the chaos.

★ OPEN SOURCE ★

// Fork the couch

Build your own
gremlin.

Couchverse is open source. The whole stack (the Chrome extension, the LiveKit agent, every persona) lives on GitHub. A persona is a single config file: write one, drop it in, summon a new co-host. Fork it, self-host it, hand it your own LLM keys, build a couch full of weirdos.

// Questions you might have

Yes, but actually:

Real answers. Click any rock to look under it.

  • Only the audio of the active tab, and only while a session is running. No mic capture unless you hit hold-to-talk. Audio leaves your machine to be transcribed and reacted to, but nothing is stored after the session ends.

  • Yep. Couchverse listens to whatever's playing in your tab. It doesn't care about DRM because it's not touching the video stream. If you can hear it, they can riff on it.

  • Three chattiness modes: Quiet, Normal, Chatty. Plus a Skip button if a take is going long. You're the director.

  • Free to start, forever for casual use. Heavy watchers get a Couchverse+ tier later, but the core experience stays free.

  • A whole roster is on the couch. You'll be able to mix and match: a film-bro, a tired mom, a goth teen, a sentient lamp. Vote on who ships next.

  • Close the Couchverse extension popup and open it again. That resets the session and clears most hiccups.
