Why copy-paste fails

AI content is easy to copy. Hard to keep editable.

ChatGPT, Gemini, Claude, and similar tools can generate beautiful equations, tables, and structured answers. But when you copy that output into Word or another editor, the structure often falls apart.

×Equations lose their proper formatting and stop feeling like real equations you can work with.
×Tables collapse into messy text blocks or spacing that needs to be rebuilt by hand.
×After pasting, editing becomes tedious because the document is no longer cleanly structured.

What MathFix does instead

MathFix turns fragile AI output into a document you can actually use.

✓Rebuilds equations and mathematical structure so the result looks intentional instead of broken.
✓Preserves tables, headings, lists, and layout in a cleaner document structure.
✓Creates a PDF preview first, then exports editable DOCX files for Word workflows when you need to keep working.

In short: instead of fixing a messy paste by hand, you get a shareable document with the formatting already repaired.

Built for AI-generated content

Everything you need to turn messy AI outputs into documents you can actually share.

AI-Powered Formatting

Automatically detects and restructures outputs from ChatGPT, Gemini, Claude, and other AI tools. Headings, lists, tables, and paragraphs are properly organized.

Full Math & LaTeX

Complex equations and LaTeX expressions render cleanly instead of turning into awkward pasted fragments. From simple fractions to multi-line derivations, the math stays readable.

Customizable Output

Choose fonts, page size, margins, line spacing, and more. Fine-tune every detail before exporting your document.

Code Blocks & Tables

Tables keep their structure and code blocks stay readable instead of collapsing after paste. Share technical content without reformatting everything by hand.

Background Fix Jobs

Longer documents can run as tracked jobs instead of blocking the screen. You can follow queued, running, completed, and failed states.

History & Credits

Keep recent fixes, use cloud-backed history when available, and see credit balance details for AI-powered document repair.

Paste, preview, export.

From raw AI output to a polished document without rebuilding the formatting by hand.

Paste Your Text

Copy output from ChatGPT, Gemini, Claude, or other AI tools and paste it into MathFix.

Run the Fix

MathFix repairs the Markdown and LaTeX structure, renders a PDF preview, and keeps the job visible while it runs.

Download & Share

Check the preview, adjust document settings if needed, then export a polished PDF or editable DOCX.
