Create a searchable help-video library for an app
A developer used Replit Agent to assemble a /help page that turns scripted walkthroughs into recorded, narrated tutorial videos.
- What they did
- The developer asked Replit Agent to add a demo-only mode at ?demo=1, seeded with fake data and no database changes. They also specified that each tutorial should be described in code as a sequence of scenes with the target route, spoken lines, and cursor actions, then captured with Playwright, voiced with TTS, and assembled with ffmpeg. The same prompt told the agent to make the process resumable, verify frames, support transcript search, and preserve full keyboard use.
- How it went
- The post did not report a launch, user numbers, or any other outcome. It simply shared the prompt after readers asked how the library had been made.
- Tips
- For a setup like this, ask the agent to stop before any destructive step so you can review the output first. It can also help to have it generate one sample video before it produces the full set.
Try it yourself with Replit Agent
Set up a /help page for [app name or URL] that can generate short tutorial videos for [feature or flow 1], [feature or flow 2], and [feature or flow 3]. Let me turn on a preview mode with ?demo=1 that uses fake seeded data and never writes to the database. Store each tutorial as code for a sequence of scenes, where every scene includes the route to open, the narration text, and the mouse or cursor actions to perform. Have Playwright capture the app while TTS speaks the script, then assemble the result with ffmpeg into MP4 files and include captions. Also produce a transcript and manifest.json for each video, make the process resumable, inspect frames before finishing, support searching across transcripts on the page, and keep the interface usable from the keyboard alone. Build one example for [feature or flow] first, then pause and ask me before making or publishing the rest.
