AI tools, coming to the editor
Image/equation → LaTeX, table screenshots → tabular, humanize AI-sounding text, fix compile errors, convert documents. The LetX AI assistant is rolling out through 2026, working directly on your project. The editor itself is free today.
Open the free editorFrequently asked questions
Are these LaTeX tools free?
Yes. Every tool on this page is free, runs in your browser, and requires no account. They exist because we build LetX, a free collaborative LaTeX editor, and these are utilities every LaTeX author needs.
Can I convert an image or handwritten equation to LaTeX?
Yes, inside the editor: Lexi, the LetX AI assistant, recreates a screenshot of an equation, a table or a layout as LaTeX with /image-to-tex. Lexi is part of Pro. The editor itself, with unlimited collaborators and 1000+ templates, is free.
What happened to the other tools?
We retired thin single-page tools and kept only the ones that do a complete job in the browser. The heavier jobs (image to LaTeX, PDF to LaTeX, converting between venues) live in the editor, where Lexi does them on your real project.
