DEVONthink 4.3

DEVONtechnologies has released DEVONthink 4.3 (aka Herschel, named after the periodic comet 35P/Herschel–Rigollet) with a few additions, including an MCP (Model Context Protocol) server, a new internal Markdown parser, and new desktop widgets. DEVONthink’s MCP server acts as a bridge between your DEVONthink databases and AI apps like Claude or Codex, allowing the AI tools to access key information and perform tasks while honoring privacy guardrails that can be controlled within settings (Exclude from Chat & MCP in the Database Properties panel). The MCP server requires macOS 15 Sequoia or later and is reserved for the Pro edition. Other improvements to the Pro edition include added support for Apple Intelligence for light tasks and Apple’s faster SpeechAnalyzer for transcription, and more reliable batch tagging with low-tier AI models (like Magistral).

MultiMarkdown 6 is now replaced by DEVONthink’s own Markdown parser and renderer, which is more compatible with AI-generated output and supports callouts, citations, and tables with captions. The document and information manager also adds new desktop widgets that enable you to load a Workspace or access your Reading List or Favorites, fixes a bug that caused the conversion of Markdown documents to paginated PDFs to fail, and addresses a regression that prevented multi-page TIFF files from being converted in macOS 26 Tahoe. ($99 new for DEVONthink, $199 for DEVONthink Pro, and $499 for DEVONthink Server with a 15% discount for TidBITS members; upgrades available; release notes; 89.7 MB; macOS 13+)
