Let me paint you a picture. It's 11pm. You're halfway through writing a section on Bayesian inference for your thesis. You need to type a posterior distribution formula — nothing exotic, just a fraction with a couple of Greek letters and subscripts.
In Microsoft Word, this is what happens: you leave the keyboard, click "Insert," click "Equation," find the fraction template, click again, navigate to the Greek letters panel, find μ and σ, click back into the numerator field, type the exponential, go back to the denominator…
Five minutes later, you have one equation. And you've broken your flow at least six times.
That was me, about 18 months ago. I'd been a loyal Word user for years, and I want to be fair — Word's equation editor is genuinely fine for simple math. If you're writing a short homework assignment with a handful of formulas, it gets the job done. But when your document has 80+ equations, when you need properly formatted matrices, when you need equation numbering that doesn't drift around when you move paragraphs — that's where it starts to fall apart.
The specific things that broke me
Here's what finally pushed me over the edge:
Equation numbering. Word's equation numbering is surprisingly fragile. Once I had a long chapter with numbered equations, and after reorganizing a few sections, a handful of numbers were wrong. Fixing them took the better part of an afternoon. LaTeX's \label and \ref system handles this automatically.
Matrix input. Word uses its own variant of UnicodeMath syntax that doesn't match standard LaTeX. So \begin{pmatrix} doesn't work — you have to use \matrix() instead. This matters when you're sharing work with collaborators who use LaTeX, or when you need to submit to a journal that wants .tex files.
Performance. Around 90 equations, Word started getting noticeably sluggish. Scrolling, cursor movement, undo — all slightly laggy. Probably the real-time rendering overhead. LaTeX compiles separately and then the PDF is static, so this just isn't a problem.
Why I was nervous about switching to LaTeX
Here's the thing that kept me from switching for too long: I assumed I'd have to memorize a ton of commands.
And yes, for common stuff, LaTeX commands aren't that bad:
\frac{1}{2} % fraction
\sqrt{x} % square root
\alpha, \beta % Greek letters
But once you get into less-common territory — tensor notation, double integrals, custom matrix environments — I found myself constantly interrupting my writing to Google the right syntax. That friction was real, and it made LaTeX feel harder than it needed to be.
Enter TeX64 and its visual math palette
A colleague pointed me toward TeX64, a LaTeX editor for macOS. I was skeptical at first — I'd used other LaTeX editors and found them either overwhelming (TeXShop, Emacs + AUCTeX) or too basic.
What won me over was the interactive math palette.
The concept is simple: it's a panel of symbols, operators, and templates organized by category. You click what you want, and the corresponding LaTeX code gets inserted into your document. But here's the key thing — it also shows you a live rendered preview of what the equation looks like as you build it.
This feels a lot like Word's equation editor (you're still clicking things visually) except the output is real, compilable LaTeX. Once it's in your file, you can hand-edit it, copy it, use it in other documents — it's just LaTeX.
For me, this bridged the gap. I could use the palette for symbols I didn't have memorized, and gradually I found myself typing common ones directly. The palette became a training tool as much as a convenience.
% Example: I used the palette to build this, then learned to type it manually
\mathbf{A} = \begin{pmatrix}
a_{11} & a_{12} & a_{13} \\
a_{21} & a_{22} & a_{23} \\
a_{31} & a_{32} & a_{33}
\end{pmatrix}
The OCR thing is genuinely impressive
TeX64 also has equation OCR built in. You screenshot or photograph a math expression — from a textbook, a whiteboard, a PDF — and it converts it to LaTeX.
I was dubious. But it works. I took a photo of a page from a signal processing textbook, pasted it into TeX64, and got back something I could use with minor edits. The accuracy on printed math is high. Handwritten equations are hit or miss, but even a 70% accurate starting point is faster than typing from scratch.
For thesis work, this is a significant time save when you're referencing formulas from papers or books and don't want to retype everything.
AI error fixing that actually works
TeX64 has an AI assistant called Axiom that reads your compile logs and proposes fixes. This matters more than it sounds.
LaTeX error messages are notoriously cryptic:
! Undefined control sequence.
l.312 \underbrace
Axiom looks at the full log, understands the project context, and tells you something like: "You're missing \usepackage{amsmath} in your preamble — this command requires it." It shows the fix as a diff so you can review before applying.
It also does natural language → LaTeX generation: "Write the formula for the normal distribution" → you get the actual code. Useful when you know what you want mathematically but can't remember the exact syntax.
SyncTeX for large documents
One feature I didn't know I needed until I had it: SyncTeX. This is the bidirectional PDF ↔ source link.
Click somewhere in the compiled PDF → your cursor jumps to that line in the source. Click a line in the source → the PDF scrolls to that part.
When your thesis is 150 pages across 8 files, this is invaluable. "Which file has the equation I'm looking for?" is no longer a problem.
The honest limitations
I want to be upfront about the downsides:
macOS only. TeX64 doesn't run on Windows or Linux. If you're not on a Mac, it's not an option.
You still need to install a TeX distribution. TeX64 doesn't include the LaTeX compiler — you need MacTeX or TeX Live installed separately. This is a one-time setup (about 20-30 minutes), but it's a real step that Word obviously doesn't require.
Not for real-time collaboration. If you're cowriting with someone and need to work simultaneously in the same document, Overleaf is better for that specific use case. TeX64 is a solo writing tool.
Heavy AI/OCR use requires a paid plan. There's a free tier to start, but if you're using OCR or Axiom heavily, you'll hit limits and need to upgrade.
So should you switch?
If you're a Mac user who writes documents with significant math content, and you've started feeling the friction of Word's equation editor — yes, I think it's worth trying.
The visual math palette removes the biggest psychological barrier to LaTeX (the "I have to memorize everything" feeling), and the rest of the editor is genuinely well-designed for academic writing workflows.
The free tier is a good starting point. You can get a real feel for it without committing to anything.
