What’s new in 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.
NEW (Pro)
- Perform AI-driven research with multiple sources, e.g., arXiv, PubMed, even your databases, with the new
perform chat researchAppleScript command. Control where AI searches with thesourcesparameter and the number of results withmaximum results.
Improved
- The appearance of placeholder text in the interface, e.g., in some empty table views, is more consistent with the system settings.
- We made some cosmetic improvements to the sidebar in the Help viewer.
- You can now load external JavaScript for Automation (JXA) scripts with a
.jsextension in the Scripts menu, as well as use them for smart rules and batch processing. - Tags separated by commas or semicolons are better parsed and applied when set via scripting.
- Updated application icon for older macOS releases and Sparkle.
Improved (Pro)
- The automatically generated identifiers of custom metadata (see Data settings) now ignore characters reserved for our search syntax, e.g.,
:. - Database searches via the Chat assistant, Chat - Query smart action, or the new AppleScript
perform chat researchcommand now filter irrelevant results. - Revisions to the internal names of Anthropic's Claude models ensure future model updates won’t break existing scripts, templates, or smart rules. Also, the AI > Research Report and The Devonian Times templates now use Sonnet's revised name.
- Gemini Pro and Flash Lite are now at version 3.1 (Preview) via the native API and OpenRouter. Also, Gemini 3.1 Pro and 3.1 Flash handle reasoning better. Note that Gemini Flash Lite 3.1 (Preview) is more expensive than the former version 2.5.
- More reliable tool of chat assistant, the Chat - Query action of smart rules and batch processing, and the
get chat response for messageAppleScript command for evaluating mathematical expressions. In addition, the constant eps0 is now also supported. - Ollama has improved support for the lfm2 model and GPT-OSS now reasons better.
- Ollama reasoning models (except GPT-OSS) enable thinking now only when using Settings > AI > Chat: Usage: Best (option is also available in the chat assistant). Otherwise it's disabled to speed up responses (e.g. up to twelve times faster in case of Qwen3.5).
- Nano Banana 2 replaces version 1 and now supports the Quality (HD or Standard) setting.
- The script assistant supports GPT 5.3 Codex via OpenRouter.
- We improved the AppleScript dictionary description of the
transcribe record… languagecommand.
Improved (Server)
- When revisiting the web sharing interface, a warning dialog will appear if you're not logged in.
Fixed
- Repairing a database with orphaned OPML documents incorrectly converted them to RSS feeds or outlines. Fixed.
- The View > Hide/Show toolbar command wasn't disabled in the Help viewer. Fixed.
- Converting an empty rich text document to plain text or Markdown failed. Fixed.
Fixed (Pro)
- Importing OPML email attachments always converted them to RSS feeds or outlines and could create orphaned files. Fixed.
Removed (Pro)
- Removed the soon-to-be-retired Claude 3 Haiku. Bulk tasks, e.g., filtering search results, are now done with 4.5 Haiku. Note that the 4.5 model is more expensive.
- Removed all Qwen3 235b models from OpenRouter, except the ones for coding. Use the latest Qwen 3.5 models instead.

Version: 3.9.8
So, DevonThink Pro is on version 4, but DevonThink To Go (iOS) is only on version 3? Is there feature parity between them?

Version: 3.9.6
You do have to be very careful what you put in there, especially complete website archives etc.. Could destroy your database (am in the process of grieving loss of over 10GB of years of archiving, won't be recuperable in any way since DTP dispatches its files in very complex ways, destroying the original structure integrity of the original hierarchy, unless using export functions.. which of course cannot be done at this point since database cannot be open. All I have access to viewing the content of the archive in Finder.. and the mess that is in there). I wonder more and more how useful this, in many ways Finder is much much less risky for organizing. Definitely not all the bells and whistles but since we're tributary to Spotlight in any case.. I used to rave about this app, not so sure anymore. I'd almost say.. stick to the Finder.. it can do all sorts of organizational tricks much less risky.

A great tool for those who need it (not for those who complain but clearly bought the wrong tool). Rock solid, well thought out. But you have to read at least part of the manual, if is not completely obvious what can and cannot be done. When SpotLight is not up to your tasks anymore, have a look at DTPro and be prepared to invest some time to learn, you will be rewarded :)

I've used DEVONthink since it was 2.x. I departed from it for a while, but I'm back and loving its usefulness. It's quite handy to use with iOS devices where Files.app is quite limited. I tried to do everything with just plain text files and folders, but I finally broke down and admitted it was a foolish idea after all. DEVONthink works quite well for capturing all kinds of info with minimum friction and maintain it in a searchable and usable way. Now that I have tried the overly-simplistic method, I can't emphasize enough how useful DEVONthink really is.
