What it does
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.
The best free Overleaf alternative. Write, edit, and compile LaTeX in the browser with unlimited collaborators. No installation required.
LetX is a free online collaborative LaTeX editor for student teams. Compile in seconds, work together in real time, and keep your unpublished work private. \documentclass {article} \usepackage {amsmath} \begin {document} \begin {align*} e^ {i\pi} + 1 &= 0 \\[1ex] \int _ {0} ^ {\infty} e^ {-x^2} dx &= \frac {\sqrt{\pi} } {2} \end {align*} \end {document} A real editing session Invite your team, edit together in real time, and compile to PDF in seconds, exactly how LetX works. Abstract — We present a framework that detects faint exoplanets in JWST/MIRI coronagraph imagery using contrastive and few-shot learning, separating planetary signals from bright host stars under low signal-to-noise.

Hi HN, Since 2019, I’ve been working on a writing platform designed for creating complex documents (e.g., theses). I personally use it for everything as it also allows to classify documents in categories so you can organize them efficiently. As of a few months ago, the app is also available in the browser, and you can now invite coworkers to collaborate on a document in real time. The app is somewhat inspired by LyX. It offers an intuitive, modern editor, but users don’t need to know any LaTeX. When it’s time to export, they can choose from a range of templates (IEEE paper, thesis, etc.). A…
Bibby AI Apr 2026 · trybibby.com · ▲165Hi, Fellow researcher from Yale, I was frustrated with Overleaf and google docs not able to write and collaborate on documents the way I wanted to. I write my research in Latex but since Cursor came out, I thought this has to change, I'm wasting too much time and having mental fog all the time, kinda going through writer's block and hence I decided to create this latex writing assistant for myself but now used by a ton of researchers, I wanted your feedback, what you like, what you don't like, alternatives you've seen, what you would like to have, nice to have, you'd definitely pay to have,…
