Congratulations to team DEVONthink on launching version 4.0, *Copernicus.* I know they’ve been working on this update for years and it shows. Some of the new features:

• DEVONthink 4 lets you integrate your choice of generative AI models for tasks like summarizing text, assigning tags, chatting with documents, and generating images.
• You can use both online AI models (like ChatGPT, Claude, Mistral AI) and local models (via Ollama or LM Studio), with full control over privacy.
• The app automatically versions documents and offers audit-proof databases, making it ideal for sensitive or financial records.
• DEVONthink 4 Server features a redesigned web interface for improved teamwork, accessible from any browser or operating system.
• Enhanced search now finds PDFs without OCR, and the new Graph Inspector helps visualize document connections.
• Automation is improved with new actions, triggers, and reusable batch workflows.
• The new license model provides one year of updates per purchase, with discounted and multi-year extension options, and continued app access even if you don’t renew.

Congratulations for a fantastic update.
