Turn your GitHub work into a video people watch.
Proof researches the angle, writes the brief, gives you a teleprompter, cuts the take, and authors the graphics. You choose the story and record it.
your repo proves you built it. nobody outside GitHub reads it.
Proof reads your README, file names and language stats. It never reads your source code, and the README is used to write your script, not stored.
Try the teleprompter
Interactive teleprompter · no account
script Proof wrote from a repo
You point Proof at your GitHub repo. It reads the README, works out what's actually worth saying about the project, and writes you a script. You read it off this teleprompter in one take, and it cuts the video for you.

This is the output. Sound on.
Abhishek read one scene off the teleprompter. Everything else on screen is Proof: the cuts, the captions, the graphics.

Projects don't die because they're bad.
They die because nobody sees them.
AI collapsed the cost of shipping. A weekend gets you a working product, so a working product stopped being the thing that sets you apart.
What did not get cheaper is attention. The bottleneck moved, and it moved to the one job most developers will not do for themselves.
Writing code is cheap now. Distribution is the moat.

“I got tired of hand-writing the same API client every time the backend changed. So I made it generate itself.”

01
OpenAI GPT-5.6
Luna handles structured extraction and drafting. Sol researches current demand, ranks angles, authors scenes, and reviews the result.
02
Whisper + FFmpeg
Word timestamps drive dead-space removal, cuts, captions, and scene anchors without chopping speech mid-word.
03
HyperFrames + Sol Vision
Bespoke motion graphics are rendered, composited over the real footage, inspected across five frames, and repaired or omitted.
We're devs who never market our own work.
so we built the thing that does it for us.
