    No more guesswork. Let the AI do the naming and categorizing. You can easily review suggestions and refine them if needed.
 
-3. **Automatic Correspondent Generation**  
+3. **Supports DeepSeek reasoning models in Ollama**  
+   Greatly enhance accuracy by using a reasoning model like `deepseek-r1:8b`. The perfect tradeoff between privacy and performance! Of course, if you got enough GPUs or NPUs, a bigger model will enhance the experience.

+5. **Automatic Correspondent Generation**  
    Automatically identify and generate correspondents from your documents, making it easier to track and organize your communications.

+6. **Extensive Customization**  
    - **Prompt Templates**: Tweak your AI prompts to reflect your domain, style, or preference.  
    - **Tagging**: Decide how documents get tagged—manually, automatically, or via OCR-based flows.
