AI LaTeX Proofreader that reads your equations

Every grammar tool you own is reading the wrong layer of your paper.

They read the prose. They will happily flag a passive sentence and leave a wrong exponent in Equation 7 sitting there with a green checkmark next to it. In an email a typo is a small embarrassment. In a paper it can change what you actually said, and the part most likely to be wrong is the part no tool is willing to touch: the math.

Benjamin is an AI proofreader built for LaTeX by scientists. He reads your equations, your units and your notation the way a careful senior co-author would, symbol by symbol, and hands the manuscript back the way a good collaborator does: a clean file plus a full set of tracked changes you can argue with.

Competitors proofread around your equations. Benjamin proofreads your equations.

The other “LaTeX-safe” tools succeed at one thing: not breaking your code. The way most of them manage it is by stepping around the math entirely. One popular guide literally tells you to replace every $...$ with a [MATH1] placeholder and drop your display equations before you proofread, then paste the originals back afterward. That keeps your .tex intact. It also means the equations were never checked at all.

Benjamin does the opposite. The equations are the point.

• Equation integrity. He checks the conceptual and formatting soundness of your math and proposes the fix: a summation index that quietly double counts, a fraction bar that swallowed a summation sign, an italic-versus-roman slip that turns a derivative into a stray variable.
• Units and notation. An Angstrom that lost its ring, a CO2 that should be CO₂, a symbol you defined once and then drifted away from twenty pages later. He watches for all of it.
• Grammar in context. Real proofreading of the prose too, aware that it is a scientific manuscript and not a blog post, so terminology stays consistent and precise.
• 95+ languages. A non-native English draft gets the same careful read. Language stops being the barrier.
• Every format scientists use. LaTeX, Word, plain text and Markdown, RTF. No reformatting before you start.
• Real tracked changes. Native Word Track Changes, or an inline LaTeX diff if you would rather stay in your source. Review, accept, or reject every edit. Nothing happens to your science without your say-so.

How it works

1. Give him the manuscript. Upload your .tex (or .docx, Markdown, RTF). Straight from Overleaf is fine.
2. He reads the science, not just the spelling. Grammar, units, notation, terminology, and the equations themselves.
3. You get it back with tracked changes. A clean copy plus every correction laid out to accept or reject, one line at a time.

Why “Benjamin”

He is named for Benjamin Franklin, a printer who caught the slips before a page ever reached the press, and a scientist who gave us the words we still use for electricity. One person with a foot in both worlds: the one who sets the type, and the one who understands what the type is trying to say. That is exactly the reader a scientific manuscript needs. If you want the longer story, we wrote about why we built him, and about the real paper whose flipped equation described a universe that eats itself.
