Yesterday a small Chrome extension popped up in r/PromptEngineering, and it’s a good reminder that the best AI tools aren’t the flashy ones. u/Actual-Abrocoma-4733 got tired of manually chopping scripts into scenes and hand-typing a prompt for each one, so they built something that does it automatically.
Here’s the twist: the goal wasn’t “build a cooler AI tool.” It was remove one annoying step from a workflow they already had. That’s the whole idea, and it’s why it works. No new model, no new interface to learn, just the copy-paste grind gone.
How it works, roughly:
- 📝 Drop in your script
- ✂️ Extension auto-splits it into scenes
- 🤖 Generates a prompt per scene
- 💾 Saves the whole batch to a file instead of one prompt at a time
Pro tip: if you’re doing any kind of video or content pipeline where you feed scripts into an LLM scene-by-scene, this is the exact shape of automation worth stealing, even if you build your own version instead of using theirs. Look at where you’re copy-pasting the same structure over and over. That’s the tell.
The extension’s still rough, and the builder is literally asking the subreddit what to fix next. So if you’ve automated a repetitive prompt task yourself, that thread is worth a comment. 🔧 Go build the thing that saves you five minutes a day, it adds up faster than people think.
