[pkarw]

We should have add additional settings like this:

[ ] Use Open Source models (OLLAMA)
OCR: [ ] Surya-CRM (better quality, slower), [ ] Tessereact (in-browser, lower quality)
[ ] Remove personal data using OSS models locally
[ ] Remove personal data using blacklist: _______________________ (enter name, first name other sensitive data)
[ ] Remove personal data before uploading files using visual annotations - related #55

Default model for chat: [ ] Open AI GPT-4o, [ ] Ollama: LLama3.1, LLama3.0 ...
