Is there a chance you'll open source the wrapper after all? It would help a lot of people like me. No pressure though, but now I really want to try it to OCR a bunch of Japanese scans I have lying around. Unfortunately, finding a good OCR for Japanese scans is still a huge problem in 2026.
chrome_screen_ai.dll is the name of the dll (libchromescreenai.so on linux) and yes it is proprietary. It isn't included by default, Chrome uses its component service to download it automatically when you open a PDF file that doesn't have pre-existing OCR'd text on it. You can download it separately from here: https://chrome-infra-packages.appspot.com/p/chromium/third_p...
It is CPU-based. Somewhere between 1 to 2 seconds per page on a single core. I ran 20 instances of it in parallel to utilize 20 CPU cores so the avg time came down nicely.
