DEVONthink 4.3 Herschel
May 2026
We named this release after the periodic comet 35P/Herschel–Rigollet, discovered in 1788 by Caroline Lucretia Herschel (1750–1848). Caroline was the sister of the famous astronomer William Herschel and made significant contributions to astronomy in her own right. She discovered eight comets and numerous nebulae and star clusters, and compiled an influential catalogue of deep-sky objects. Caroline Herschel was the first known professional female astronomer, became the first woman to receive a salary as a professional astronomer, and received the Gold Medal of the Royal Astronomical Society.

DEVONthink 4.2 Cassini
January 2026
We named this release after the Cassini lunar crater and its namesake, Giovanni Domenico Cassini (1625–1712). The Italian-French astronomer served as the first director of the Paris Observatory. Cassini was a methodical observer and organizer of knowledge, systematically cataloging celestial phenomena and discovering four of Saturn’s moons and the division in its rings. His dedication to precise observation and documentation lives on as one of the foundational principles of science.

DEVONthink 4.1 Europa
September 2025
This version is named after Europa, Jupiter’s fourth-largest moon. It is a captivating world encased in an icy shell that hides a global subsurface ocean, one of the most promising locations for extraterrestrial life in our solar system. Discovered in 1610 by Galileo Galilei, its name, rooted in Greek mythology, reflects its enduring allure as a symbol of curiosity and the unknown.

Further automate your workflows by using natural language for creating your own scripts. Use AppleScript or JavaScript for Automation (JXA) to make scripts for smart rules, reminders, or extending DEVONthink’s menu.

Refine images, generated or dropping in your own, with AI by applying additional prompts until you get a perfect result. Remove objects, change the time of day, or put people into a new surrounding.

DEVONthink 4.0 Copernicus
July 2025
We’ve dedicated this version to the Copernicus lunar crater and its namesake, the Polish astronomer Nicolaus Copernicus (1473–1543), who revolutionized our understanding of the universe. Contrary to the prevailing view that the Earth was the center of everything, he proposed that the Earth revolved around the Sun. This crater, with its rays extending across the lunar surface, is as notable as the groundbreaking ideas of the man it honors.
The new chat assistant analyzes selected documents or texts, allows you to interactively work with text, or performs actions. Generative AI is optional and supports providers such as OpenAI, Anthropic or Mistral AI, as well as locally installed models via e.g. Ollama or LM Studio for privacy.

For changes to documents, such as text documents or PDFs, DEVONthink can automatically create versions that you can return to later if necessary. You can set how many versions it should keep, how much space they may use, and how long before DEVONthink removes them.

Revision-proof databases restrict editing of documents and log deletions. Export an audit log at any time to prove that your data is consistent. Suitable for financial documents or other documents with special requirements for revision safety.
