Thumbnails and illustrations in our own style now cost a few cents each, with no designer.
Every video needs a thumbnail, every article an illustration. Instead of a designer on call or generic stock images, two small in-house tools generate them in our own style, learned from our own examples.

Costs from the tools' own usage logs, October 2026.
Visuals were the bottleneck of every publication.
A video without a good thumbnail is not watched. An article without an illustration looks unfinished. Each visual meant a designer's time or a stock image that looked like everyone else's.
We needed a consistent style, fast, without a design team.
Tools that learn the style from examples.
The thumbnail tool learns our style from examples we upload: framing, typography, colours. It renders four variants at a time, which we refine with a sentence.
The illustration tool draws our recurring character in our pastel style, from four angles, so every article and video has visuals that belong to us.
Teach
Upload a few examples of the style you want. The tool learns it once.
Ask
Describe the video or the article in a sentence.
Choose
Four variants come back side by side. Pick one, or refine it in plain language.
Publish
The image is exported at the right size, ready for YouTube, the blog or social media.
Before and after.
Before How it worked
- A designer needed for each visual
- Stock images that look like everyone else's
- Thumbnails made at the last minute
- No consistent style across channels
After How it works now
- Four variants for every request
- A style learned from our own examples
- Visuals ready before the video is
- One recognisable style on every channel
Visuals went from a request to a designer to a sentence typed by whoever publishes.
