A few years ago, creating math worksheets usually meant opening Microsoft Word, fighting with the equation editor, and spending far too much time adjusting symbols.
Today, that’s no longer necessary.
There are dozens of browser-based equation editors that let you write fractions, square roots, matrices, and calculus formulas in seconds. Most of them are free, and many work better than traditional desktop software for everyday teaching.
Over the past week, I compared several popular tools with one simple question in mind:
Which ones actually make writing math easier?
Not which editor has the most features. Not which supports every LaTeX package.
Just the tools that teachers and students are most likely to enjoy using.
Here’s what I found.
What Makes a Good Online Equation Editor?
Almost every free online equation editor can insert fractions or exponents.
That isn’t what separates a good editor from a frustrating one.
After testing different options, four things mattered much more than I expected.
- How quickly you can build an equation
- Whether beginners can use it without learning LaTeX
- How easy it is to copy formulas into documents or presentations
- Whether it works smoothly in a web browser
If an editor gets these basics right, you’ll probably use it every day. If not, it usually ends up forgotten after the first week.
1. NovaMath — Best for Everyday Teaching
If your job involves creating worksheets, quizzes, or classroom handouts, NovaMath is one of the easiest places to start.
Instead of asking users to remember LaTeX commands first, the editor focuses on visual input. Common symbols such as fractions, powers, roots, matrices, and Greek letters are only a few clicks away. When you need the source, the LaTeX bar stays in sync—handy for Word, Markdown, or Overleaf later.
What stood out most wasn’t the number of symbols—it was the speed.
Building an algebra worksheet felt surprisingly smooth because there were fewer interruptions. I wasn’t constantly searching through menus or fixing formatting issues afterward.
For teachers preparing materials every week, that small difference quickly adds up. If you’re new to the canvas workflow, the online LaTeX editor basics walk through templates to source in a few minutes.
Best for
- Math teachers
- Students
- Homework creation
- Classroom worksheets
2. CodeCogs — Best if You Already Use LaTeX
CodeCogs has been around for years, and there’s a good reason it’s still popular.
If you’re already comfortable writing LaTeX, you’ll probably feel at home immediately.
The editor supports a huge range of mathematical notation and can generate high-quality equation images for websites and documents.
That said, I wouldn’t recommend it to someone learning math notation for the first time. The interface feels more like a developer tool than something designed for classrooms.
For experienced users, however, it’s still an excellent math formula editor.
3. Mathcha — Surprisingly Powerful
Mathcha was the biggest surprise during testing.
At first glance it looks like another equation editor, but after spending some time with it, you realize it’s closer to a complete mathematical workspace.
Besides writing formulas, you can build diagrams, organize notes, and export documents to LaTeX.
The trade-off is complexity.
If you only need to type a few equations for tomorrow’s homework, Mathcha may feel like overkill. But for university students or researchers, the extra features can be worth learning.
4. Overleaf — Best for Academic Writing
Overleaf isn’t just an equation editor.
It’s an online LaTeX environment used by researchers around the world.
If you’re writing journal papers, theses, or technical reports, it’s hard to beat.
For everyday teaching, though, it’s often more than you need.
One thing became clear while comparing these tools: many teachers don’t actually need a full LaTeX workflow. They simply need a quick way to create clean mathematical expressions.
That’s where lighter online editors usually win—especially when the goal is a printable worksheet, not a journal submission. For handouts that still need source you can revise later, see inserting math into Word and PowerPoint.
5. Google Docs Equation Editor — Good Enough for Simple Tasks
Sometimes the easiest option is already installed.
Google Docs includes a basic equation editor that works well for simple algebra and classroom notes.
It’s free, collaborative, and available from almost any device.
Its biggest limitation appears once equations become more complicated.
For advanced calculus, matrices, or longer expressions, you’ll probably find yourself switching to a dedicated online equation editor before long. There’s a practical workflow for that: type math symbols online, then paste into Docs or Slides.
Which Editor Should You Choose?
After comparing all five tools, I don’t think there’s a single winner.
The right choice depends on what you’re trying to accomplish.
If you’re preparing worksheets every day, a visual editor like NovaMath saves time.
If you’re writing research papers, Overleaf remains the obvious choice.
If you’re comfortable with LaTeX, CodeCogs offers excellent flexibility.
And if you only write an occasional equation, Google Docs may already be enough.
Choosing the “best” editor isn’t really about features.
It’s about how quickly you can go from an idea to a finished equation.
A Few Things I Didn’t Expect
One interesting thing I noticed while testing these editors was that almost every modern tool supports the same mathematical symbols.
Fractions?
No problem.
Integrals?
Also easy.
Matrices?
Usually available.
The real difference isn’t what they can create.
It’s how much friction they add while you’re working.
Saving just a few seconds per equation doesn’t sound like much.
But when you’re building an entire worksheet with thirty or forty questions, those seconds become minutes. Over the course of a school year, they become hours.
That’s something feature comparison tables rarely tell you.

Frequently Asked Questions
What is the best free online equation editor?
If you’re a teacher or student looking for a balance between simplicity and functionality, NovaMath is one of the easiest options to start with. Researchers may prefer Overleaf, while experienced LaTeX users often choose CodeCogs.
Do I need to learn LaTeX?
Not necessarily.
Many modern equation editors let you build formulas visually, making them much easier for beginners. You can always copy LaTeX later when a document or paper needs it.
Can I use an online equation editor on a Chromebook or tablet?
Yes.
Most modern editors run directly in the browser, so they work on Windows, macOS, Chromebooks, tablets, and even smartphones.
Final Thoughts
There has never been a better time to write mathematics online.
Whether you’re preparing tomorrow’s lesson, finishing homework, or writing a research paper, today’s free online equation editors are faster, easier, and more accessible than the desktop software many of us used just a few years ago.
If you’re only creating a handful of equations each month, almost any editor will do.
But if mathematics is part of your daily work, spending a little time finding the right tool is absolutely worth it.
After all, the best math formula editor isn’t the one with the longest feature list—it’s the one that quietly helps you finish your work faster.
Try NovaMath in the browser with one problem from this week’s homework—that’s usually enough to tell whether the friction is gone.
