Stop fixing LaTeX one by one.

Drop your file, get every equation.

Pasted a ChatGPT answer, built a worksheet, or wrote a paper in Word? Convert every piece of LaTeX in your document at once — no equation editor, nothing leaves your browser.

Before

The area is $\frac{1}{2}bh$ and the root $\sqrt{x^2+y^2}$ appears in \[E = mc^2\]

After

The area is ½bh and the root √(x²+y²) appears in E = mc²

⚠ Your document must already have math in LaTeX delimiters — $…$ , $$…$$, $…$, \[…\], or [ … ]. Bare LaTeX like \frac{1}{2} is left as plain text.

Not in that format? Ask ChatGPT: Write every formula in LaTeX — $...$ for inline, $$...$$ for display. Never write math as plain text.

What LaTeXFlow Scan does

When you write math as LaTeX inside a Word or Google Docs file — for example $\nabla \cdot \vec{F}$ or $$E = mc^2$$ — it stays as plain text. It looks fine while you type, but the moment you build slides, hand the file to a co-author, or export a PDF, every formula shows up as raw backslashes and braces.

LaTeXFlow Scan reads a .docx file, finds every piece of LaTeX in it, and gives you back the same document with each formula replaced by a rendered image. No equation editor, no retyping, and no formula ever leaves your browser — the whole conversion runs on your own machine.

How it works

Bring your file in. Drop a .docx onto the page, or use Import from Google Drive to pull a Google Doc in directly. The Drive import uses the limited drive.file scope, so the tool can only see the single file you pick — never the rest of your Drive.
Detection. The scanner walks the document and collects every span wrapped in a LaTeX delimiter (see the table below).
Review. Each detected formula gets a live preview. Skip anything that was caught by mistake (a stray $100, say), and resolve ambiguity cards where a paragraph has an unclosed $ — the tool asks you to pick the boundary instead of guessing.
Render & export. Press Render PNG · Export and download a .docx in which every formula is now a crisp PNG. The original LaTeX is preserved in each image's alt text, so the document can be converted back later.

Supported LaTeX delimiters

A formula is only detected if it already sits inside one of these delimiters. Bare LaTeX with no delimiter — \frac{1}{2} on its own — is treated as ordinary text and left untouched.

Delimiter	Example	Detected
$ … $	$x^2 + y^2$	Inline math
`$$ … $$`	`$$E = mc^2$$`	Display math
`$ … $`	`$a_i$`	Inline math
`\[ … \]`	`\[\int_a^b f\,dx\]`	Display math
`[ … ]`	`[\lim_{x\to0}\frac{\sin x}{x}]`	Bracket mode — for AI-chatbot output whose backslashes were stripped by markdown. On by default; toggle it off if it over-detects.

When people use it

Google Docs class notes → clean slides

Students jot equations as LaTeX while taking notes, then need presentable formulas for a presentation. Import from Drive, convert, done — no re-typing before the deadline.

A Word paper full of equations

A draft written in Word with dozens of inline formulas would take an afternoon to fix by hand. One pass converts them all. (If you need true equation numbering and cross-references, write the paper in LaTeX instead — this tool is for turning existing documents into clean, shareable output.)

AI chatbot answers pasted into a doc

Paste a ChatGPT or Claude answer into a .docx and the display math often arrives as [ … ] — the outer backslashes were eaten by the chat window's markdown. Bracket mode catches exactly that case. Tip: ask the chatbot for $…$ and $$…$$, and paste it as text — don't ask it to “make a .docx”, or it exports Word math objects this tool can't read.

Frequently asked questions

Does my document get uploaded to a server?

No. Detection and rendering happen entirely in your browser. Nothing about the document is sent anywhere to perform the conversion.

Can I get the original LaTeX back from an image?

Yes. Each exported PNG stores its source LaTeX in the image alt text (an AIMATH_FORMULA::v1:: tag), so a formula can be recovered — for instance with the LaTeXFlow Google Docs Add-on.

Some of my equations weren't detected.

Check that each one is wrapped in a supported delimiter, and that a display formula ($$…$$) sits within a single paragraph — a formula split across paragraphs isn't detected. Native Word/Docs equation objects aren't read either; the tool works on LaTeX written as text.

A price like $100 got picked up as math.

That's expected — a lone $ looks like an opening delimiter. Just Skip it in the Review step, or resolve it from the ambiguity card.

Do I need to sign in?

Only if you use Import from Google Drive, which needs Google sign-in for the file picker. Drag-and-drop of a .docx needs no account at all.

Privacy

The document you convert never leaves your browser. To train future equation-recognition models, the LaTeX source and rendered image of each equation are collected anonymously — never your document text, file name, or email. Google Drive import is scoped to drive.file — the single file you choose in the picker, nothing more. Full details, and how to opt out, are in the Privacy Policy.
