Version History

New  Improved  Fixed  Removed

Version 4.4 Tycho

DEVONthink 4.4 turns the AI assistant into a true co-worker. A new AI library lets you create, store, and sync roles, prompts, and skills that can trigger your smart rules, batch processes, and scripts on demand. In addition, the Chat assistant can use DEVONthink's MCP tools directly and improved prompt caching makes multi-step tasks noticeably faster and much cheaper. Of course, we have also updated to the latest models of all major AI providers.

Markdown takes the second spotlight with WYSIWYG support for live tables and MathJax equations, a new syntax colorizer, custom color themes, and direct export to LaTeX or typesetting as PDF via pdflatex. Web clipping is also faster and more accurate, using a new, local Markdownifier and Readability engine. The new Reader view lets you read web content distraction-free.

Finally, encrypted and revision-safe databases use modern APFS images on macOS 26.0 Tahoe and later, and the help viewer's chat assistant is available for free in all editions.

Version 4.3.2

This maintenance release adds support for Anthropic's latest frontier model, Claude Fable 5, as well as image diffusion models via Ollama. We optimized the search tool in the MCP server and added a built-in connector for LM Studio to access it. Additionally, DEVONthink can redact many national identification numbers before AI use. For research automation, four new AppleScript commands let you locate and apply bibliographic metadata, and in the web interface, you can now print PDF documents you're viewing. We also fixed compatibility with macOS 27 Golden Gate Developer Beta.

Version 4.3.1

This maintenance release further refines the new DEVONthink Markdown parser with options like better image styling and captions, improved inline footnotes, and some fixes. This release also improves the MCP server, including safer handling of custom metadata, setting item aliases, opening documents externally, and using OpenLibrary as a fallback for Google Books. Additionally, we updated some image-generation AI models and now support Claude Opus 4.8.

Version 4.3 Herschel

DEVONthink 4.3 Herschel introduces our MCP server: A safe, private bridge that lets Claude, Cowork, Codex, and other AI clients work directly with your databases. No scripting or third-party tools required. On macOS Tahoe, we now support Apple Intelligence for light tasks and Apple's faster SpeechAnalyzer for transcription. Other AI improvements include a leaner search assistant, a dedicated tagging model, and web search via ollama.com.

A new Markdown parser and renderer replaces MultiMarkdown 6. It adds callouts, citations, and better compatibility with AI output. Desktop widgets bring the reading list, favorites, and workspaces to macOS Sequoia and later. For DEVONthink Server users, the web interface gains classification, context menu commands for moving, duplicating, and replicating items, and a dialog for opening item links. It also features a much better PDF viewer. As always, reliability and performance continue to improve.

Version 4.2.2

Today's maintenance release lets you create powerful AI-driven searches and add tags more reliably via scripting. If you are using JavaScript for your automations, you can now use .js files. In AI, Gemini and Nano Banana get updates, and Claude 3 Haiku retires. We also have a few fixes, including better handling of .opml email attachments.

Version 4.2.1

This maintenance release lets you mirror DEVONthink reminders to Apple Reminders via a new script. It also includes a hidden preference to disable dark mode only for PDF documents on macOS Tahoe or later, and lets you run batch processing on specified records via AppleScript. The Pro and Server editions support Claude Sonnet and Opus 4.6 and improve the support for zAI and Qwen models. The update brings several fixes, too, e.g., for lists in rich text documents not displaying on macOS Tahoe.

Version 4.2 Cassini

DEVONthink introduces a refreshed look with a new app icon and full support for Apple's Liquid Glass design on macOS Tahoe. On macOS Sequoia and later, sidebars and inspectors now animate smoothly in and out, and the Navigate sidebar is spring-loaded. Simply drag items to the window edge to reveal it automatically. PDF documents on Tahoe also respect your dark mode preference for more comfortable reading.

The Chat assistant gains powerful new capabilities: adjust many options directly within the chat window, and access up to 50 saved conversations to pick up right where you left off. You can now choose between DEVONthink, Perplexity, or Exa for web and Wikipedia searches, giving you control over speed versus freshness. Updated AI models including Claude 4.5, GPT 5.2, Gemini 3, and Google Nano Banana Pro, deliver improved performance across all AI use. When generating images, you can choose the aspect ratio.

New workflow tools help you work faster: the detachable Graph popover lets you visualize document connections, you can manually save named versions for finer revision control, and annotation files are now easier to create, locate, and open directly from menus and inspectors. Markdown documents also support smart quotes and dashes for polished typography.

Version 4.1.1

This release helps mitigate AI risks, especially when processing online content, to reduce the potential for malicious prompt behavior. We also updated the supported AI providers, adding support for Google's Nano Banana image engine and Anthropic's Claude 4.5 Sonnet.

DEVONthink now detects empty pages when clipping PDFs, ensuring more consistent and useful results, and we made the Safari and share extensions more reliable on macOS Tahoe. Mailboxes in the Import sidebar load faster and match Apple Mail's appearance and you can modify a document's searchable text via the chat or scripting. On the sync side, DEVONthink now automatically adjusts resource usage based on your machine's temperature and workload, and sync in general is more performant. Of course, we fixed bugs and glitches, too.

Version 4.1 Europa

Here it is, the first feature release for DEVONthink 4. Choose from a much wider range of server-based AI models via OpenRouter or by connecting to just any OpenAI-compatible provider. Integrate models from, e.g., Amazon, Meta, Microsoft, xAI, Baidu, Moonshot AI, Qwen, and more. In addition, DEVONthink Europa adds native support for Claude 4.1 Opus, Gemini 2.5 Flash Lite, OpenAI GPT-5, Google Imagen 4, and the latest models by Mistral. Connect to your institution's Ollama installation with a new configuration option.

To further automate your work, describe your task to the AI-powered script assistant. It generates AppleScript and JavaScript for Automation (JXA) scripts and even corrects common scripting issues. Edit images, both generated or dropped in from other sources, with prompts using common AI image generation models. As generative AI is notoriously bad at maths, the Chat and other AI-assisted functions now support mathematical functions, and if you're working in academia, retrieval-augmented generation (RAG) gets direct access to the huge document collection on arXiv. In addition, DEVONthink Europa comes with a new Quick Look extension for previewing Spotlight results on macOS Sequoia and later, and more responsive editing of especially larger Markdown documents. It also updates and sorts lists and empties the trash significantly faster.
