Overleaf is the collaborative LaTeX editor most academic writing runs through – real-time co-authoring, version history and compilation in the browser, with no local TeX installation to maintain.
Overleaf AI adds LaTeX-aware assistance to that workflow, and the specificity matters. LaTeX is exactly the kind of syntax a general assistant handles unreliably – package conflicts, environment nesting, bibliography and cross-reference behaviour – and errors surface at compile time rather than as you type. An assistant that understands the document format is answering a different question from one improvising markup.
Institutional paths exist for universities, business, government and publishers, alongside a large template library covering journal and thesis formats. There is a free tier, with paid plans for longer compile times and more collaborators. For anyone writing a thesis or a paper, template compliance alone often justifies it.
