The hook
“You shipped the code. Your docs didn’t get the memo.” Two lines that name a pain every developer knows, before the product is even named.
SaaS product demo · Concept
Driftlens
Docs that keep up with your code.
A 23-second product demo for a concept AI tool that keeps developer docs in sync with the code. One real change travels from a pull request to the docs, so the value is obvious without a voiceover.

The brief
The problem
Stale documentation is an invisible problem. Nobody notices it until a developer copies an example that no longer works, which makes it hard to show in a short video.
The idea
Make the invisible visible: follow one API change from the code to the exact sentence it breaks, then let the product fix it on screen. Three beats, no narration.
How the story plays
Beat by beat.

A pull request changes the API
Login switches to passwordless. auth.login(email, password) becomes auth.signIn({ email, otp }) and Driftlens starts scanning 24 pages of docs.

It finds the docs it breaks
A line runs from the changed code to the exact sentence on the Authentication page. Doc health drops to 72% and one page is flagged out of date.

AI writes the fix. You approve.
A suggested update appears beside the stale line. One click on Apply fix, health climbs to 100% and a docs pull request opens by itself.
