This. I am reading old vital records in my family genealogy quest, and as those are sometimes really difficult to read, I turned to LLMs, hearing they are great in OCR. It’s been… terrible. The LLM will transcribe the record without problems, the output seems completely correct, a typical text of a vital record. Just… the transcribed text has nothing to do with my specific record. On the other hand, transkribus.eu has been fairly usable for old vital record transcription – even though the transcribed text is far from perfect, many letters and words are recognized incorrectly, it helps me a lot with the more difficult records.
