LetX vs Prism

LetX has no write-up on Specifiction yet; its figures are above.

Prism is a web-based, LaTeX-native workspace for scientific writing and collaboration. Its project-aware assistant can work with a manuscript’s structure, equations, references, and surrounding context. Writing tools include proofreading, citation management, equation conversion, and automated error checking. Researchers can search for literature, including arXiv, and incorporate relevant material into projects. Real-time collaboration supports edits, comments, and revisions with unlimited collaborators. Optional voice editing handles simple changes. Projects can be imported by uploading a folder or ZIP archive, or by dragging files into the All Projects view. Prism syncs with Zotero for citation search, but Zotero group libraries are not supported. It runs in a web browser and offers a Free plan at free, including unlimited projects, collaborators, compile time, and compile speed. Access is limited to users with Free, Go, Plus, or Pro ChatGPT accounts who are not, and have not been, members of a Business or Enterprise workspace. Git integration is not available yet.
