Most AI tools hand you LaTeX and hope it builds. Lexi works inside the project: it 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. On paid plans, Claude or ChatGPT can work on the same project over MCP. 1,000+ templates. Unlimited collaborators on every plan; Overleaf's free tier allows one. Team plan for labs and classes: $20 per seat.
