What now?

Did you make something worth sharing?

Publishing is optional. Nothing goes public unless you choose it.

How was it?

Build in public

3 clips from your session with Marco

Made from the recording you both agreed to. Tap a clip to preview it. Nothing is shared until you both approve.

Recordings stay private. Clips are only shared when you both approve. Full recordings auto-delete after 30 days unless you both publish.

We record each camera and the screen separately, so clips can be laid out for phones.

Never make clips from my sessionsYour future recordings stay as full recordings only.

Prototype: projects and numbers are examples.
