Post your weekly build-in-public update

One real story from your week, posted every Friday.

On X with a clip or screenshot, and on LinkedIn too.

Download RiverHow to start

How it works.

River finds the most interesting thing your team shipped this week, shows it working in a short clip or screenshot, and writes the X post and a LinkedIn version in your voice, keeping private things private.

  1. Draw the private line

    You choose what stays off the page, from revenue to what’s coming next.

  2. River picks one story

    From finished work, releases and what customers said, the change a stranger would stop for.

  3. It shows the product working

    A 10 to 20 second clip or a clean screenshot, with sample data on screen, never a customer’s.

What you get.

  • A weekly X post in your voice with a clip or screenshot of the real product
  • A LinkedIn version that tells the same story at LinkedIn length
  • A Build in public folder with each week’s post, clip and how it did

A few things to know.

Won’t building in public give too much away?

You decide what stays private on the first card, and revenue and customer names stay out by default. River picks stories that are interesting to follow, not easy to copy.

Do I see each week’s post first?

Yes. Each week’s post, clip and LinkedIn version come on one card and go up only after your yes. Then River answers replies for a day.

What does it cost?

It uses your plan’s AI credit, like everything else in River. The clip is filmed and trimmed in River, with no screen recorder to install.
