# MyJourney: create product demos without wasting a day

**[The Miners](https://daily.dev/sources/miners)** · 13 min read · 0 upvotes · 0 comments

## Summary

MyJourney is a tool that automatically generates narrated product demo videos. You provide a URL and a description, and it uses Claude Opus to plan a tour of the site in a real browser, compiles the plan into a Playwright script via a custom DSL (the model writes JSON, never code), records the session using Chromium's CDP screencast, and assembles the final MP4 with voice narration, lip-synced presenter, and branding using ffmpeg. Key design decisions include: a human approval step before recording, safety guardrails that block destructive actions, a human-handled login flow, quality gates for motion and composition, and a cost of roughly $0.30 per tour. The architecture is intentionally minimal — two processes and a database, with the queue implemented as a database table.
