LetX

LetX is an AI tool described by its creators as “Write LaTeX together. The AI runs the build”.

Most AI tools hand you LaTeX and leave you to paste it somewhere and hope it builds. Lexi works inside the project: it creates and edits files, builds tables and TikZ diagrams, fixes your bibliography, compiles, reads the real latexmk log, and fixes what it reported. Every edit snapshots first, so it can be reverted. Connect Claude or ChatGPT over MCP and they get the same project: 1,019 templates, create, edit, compile. Unlimited collaborators on every plan. Overleaf's free tier allows one.
