I haven’t enabled anything of this nature. Could you please let me know where the setting to disable it is? I can only see the Apple Vision transcription setting under the AI tab, but here we’re talking about indexing during the import of files (either PDF document or PDF+Text type). @cgrunenberg didn’t suggest turning off Apple Vision to test the import, so it’s likely the issue lies elsewhere.
Yes, this is the AI tab (KI in your case). I’m sorry, but it has nothing to do with my issue.
That’s a feature of DEVONthink 4 and automatically applied to PDF documents/pages without a text layer to make them immediately searchable.
This preference is only relevant for images.
You probably mean images like PNG, jpeg, WebP? Because a typical PDF delivered by a scanner is very much an “image”, too.
