Interesting. Looks like it has similar results to Tesseract. I wonder how the Mastodon tool handles images with graphics as well as text?
A noble goal 
Whilst I share the desire for excellent results, I’ll be happy with an 80% improvement 
In the context I have in mind, the goal is to extract things like error messages from screenshots. For example, if a user has an error log in their terminal, the tendency is to just screencap it. Even if the result isn’t perfect, if it extracts about 80% of the text correctly, then someone searching for the error message, or another related piece of text has a far higher chance of finding the Topic, than if it was just the unsearchable image.
