\usepackage{ai-assistant}

Your AI reads LaTeX.

Not just autocomplete. FormaTeX ships a full AI assistant that understands your source, your error logs, and your intent — so it can fix, explain, generate, and discuss your documents.

\begin{ai-modes}

Four modes. One assistant.

Every mode operates on your full document — not just the line you're on. The AI sees your source, your error log, and your compilation history.

Fixrewrites your LaTeX

Paste the error log. The AI reads it alongside your source and rewrites the offending section — not a guess, a targeted fix from the actual compiler output.

- \int_0^{\infity} e^{-x^2}\,dx

+ \int_0^{\infty} e^{-x^2}\,dx

line 6 · \infity → \infty · 1 change

Explainplain English

LaTeX errors are famously cryptic. The AI translates compiler output into plain English with the specific location, root cause, and a fix suggestion.

! Overfull \hbox (8.4pt too wide)

Your text exceeds the column width by ~8pt. Try adding \linebreak before "infrastructure" on line 14.

Generateprompt → LaTeX

Describe what you need in plain language. The AI writes production-ready LaTeX — tables, equations, environments, bibliography entries — in the style of your existing document.

Chatfull context

Ask anything about your document. The AI has your entire source as context — not just the current paragraph. Ask about structure, packages, citations, or style decisions.

\compare{ai}

Not Overleaf's autocomplete.

Overleaf added AI features — they're useful. But they operate at the token level. FormaTeX AI operates at the document level.

Overleaf AI

–Inline autocomplete — completes the current command
–Error messages rephrased — describes what went wrong
–No full document context
–No generation from natural language prompts
–No conversational mode

FormaTeX AI

+Fix — rewrites the broken section using the compiler error log
+Explain — root cause, plain English, exact location
+Full document source available in every interaction
+Generate — produce LaTeX from a natural language description
+Chat — conversational with persistent document state

AI on every plan. Free to start.
