I’m not a great artist — so I made an agent that turns my doodles on my Remarkable tablet into actually nice charcoal sketches. Real editable pen-line vectors too! Not just static images.

About This

Pretty much what the title says.

- Doodle
- Select
- Agent parses device screenshots to write creative brief
- Another agent gets the brief and napkin sketch and makes an image of charcoal artwork
- Post-processing pipeline does multiple layers of vectorization (line work, shading, highlights)
- All vectors are converted to Remarkable pen-stroke data and injected into the clipboard and pasted onto the tablet in place of the original sketch

1 undo step to get back to your sketch. Feels like magic. Brief agent is Qwen, Image gen agent is Nano-Banana-Lite with Qwen doing QA on the resulting image to make sure it adhere's to the brief. Each generation is currently about $0.04 in API costs per image generated during an attempt — agent is limited to 3 attempts and if all "fail" then Qwen returns the one it feels _best_ matches.
