The Meitner Update acknowledges that research rarely follows a straight path and that scientific insights constantly evolve. You can now branch new chats from any point in an existing conversation within scienceOS. This feature lets you explore alternative hypotheses or interpretations while maintaining a clear link to the original idea that inspired them.
Similarly, with the new version of scienceOS, saved answers can now serve as starting points for new discussions. You can start a new chat from any of your saved answers – or from a colleague’s saved answer if you are both part of the same shared project. This makes it easier to build on existing insights, draw inspiration, and explore new perspectives.
Finally, to help you manage all your uploads, you can now delete uploaded files from your scienceOS library and account. Simply select listed or unlisted sources in your library and choose the option ‘Delete source’.
Branching chats

Use the branching icon in a chat to begin a new thread from this point and explore further ideas.

Building on insights

Branch from your or a colleague’s saved answer to start a new chat and build on gained insights.

Why Meitner Update?
This update of scienceOS is dedicated to Elise ‘Lise’ Meitner, who developed the physical explanation and theoretical framework for nuclear fission, the process by which an atomic nucleus splits into smaller parts, releasing energy and giving rise to new elements.
The “Trust in AI” survey.
ScienceOS was developed to assist researchers while respecting their autonomy, expertise, and ethical considerations. We invite you to take a short survey to share how scientists like you experience and trust AI tools such as scienceOS. Your insights are essential for shaping AI that supports rigorous, responsible, and transparent research.
The survey takes 2:45 minutes, and your perspective will directly influence the ongoing development of scienceOS. Take the survey.
Improvements and bug fixes.
We implemented improvements related to (shared) projects, made comfort adjustments, improved the accuracy of the scienceOS AI agent, and fixed some bugs.
Improvements
- Made searching in your library during project creation more powerful
- Added information about location of PDFs uploaded to a chat
- Replaced “My uploads” in settings with list of unlisted sources in library
- Added a screen to help users that cannot login due to timestamp failure
- Improved answer accuracy of AI agent
- Integrated quick filters for project feeds and my feed
- Many improvements related to projects, project chats, and saved answers
- Added rename and delete/leave to all project menus
- Removed visual clutter to increase simplicity
- Implemented warnings for leaving shared projects
Bug fixes
- Fixed a bug where mathematical formulas were rendered incorrectly
- Fixed a bug where the AI agent would stop responding in very long chats
- Fixed bugs related to citation summaries
