How it works
- Step 1
Fill in a few fields
Plain-language inputs — video title, what's the video about?, text on the thumbnail, …. No settings, no jargon.
- Step 2
Click “Generate thumbnails”
The workflow runs behind the scenes — on your machine or with your own provider keys. You pay providers directly, or run local models for free.
- Step 3
Watch results stream in
Results appear live in the app: thumbnails.
It's an app until you want more
Every mini app is a real NodeTool workflow underneath. Open the canvas to swap models, change prompts, or add steps — then publish your remix as a new app for your team.
