Honestly, this is one of those things where you need to define what AI means. Paperless 2.x used a machine learning-backed OCR library called Tesseract that has been in development since 1985.

The current version does use a LSTM neural network, since 2018. Is that an AI? Fuck if I know because AI is a basically meaningless term.

It’s not an LLM or a diffusion model, which is what backs a lot of the things people are calling AI nowadays.
