Well that is something i also have read online. Thats the reason why i think of using n8n

1. upload picture from some app (maybe something like telegram chat or email)
2. workflow in n8n mistreal ocr and an ki tool to sort the infos in an upload ready format for firefly III
3. and dann some api magic to paperless so that the same picture is stored in the right folder. and is archived.

Thats the workflow which should be feasible. i think i have brainstormed with ki (say what you want) and i think thats the plan i try to implement first.
