Corca

Collaborative Math Editor. Typing math should be as natural as typing text or code.

Text is a string. Math isn’t. It grows in every direction into multi-line structures. That’s why people still do math on paper. We’re bringing that experience to computers. Corca is WYSIWYG math editor, and it's fast!

Most math-heavy work is trying things, getting stuck, changing the model, asking questions, realizing you were solving the wrong problem. It’s also notes, calculations, simulations, graphs, AI conversations, and half-finished ideas.
We think those things belong in the same place.

You can just type matrices in Corca directly from the keyboard.

Shift+Enter adds rows.
Shift+Space adds columns.

[Corca @Corca_math]

Type “integral,” get ∫(x)d(x). That’s basically it. No backslashes or commands. You just type, and it turns into notation.

That's the entire learning curve.

Hints are taking care of the mechanical math—evaluating sums and products, factoring and expanding expressions, working with matrices, computing statistics, and using variables defined earlier in the document.

Ok, the cool part: math is automatically hyphenated, and you can align equations by the equals sign

We haven’t posted here in a while, so let’s unpack what we’ve been working on over the past few months, one by one. Starting with something small but important:

Automatic units. Add units to your variables once, and they carry through every calculation automatically. Set v = 10 m/s and t = 2 s, and distance comes out in meters. Nothing crazy, but a lot of people asked for it

We also changed the location of the team switcher. You know, just to make things a bit more consistent 🧐

✅ Duplicate a folder is another small feature you asked for

@WilsonCazarre You can use Corca as a replacement for Notion or Obsidian…

We launched the Daily Math Challenge. As you solve problems, AI evaluates your work in real time. Pretty cool!

[Daily Math Challenge @DailyMathC]

Today we’re launching the Daily Math Challenge on Corca!

From the beginning, our goal has been to democratize math. Strong math skills correlate with success in life—yet society accepts the idea that it’s fine to be “not a math person.”

[Corca @Corca_math]

@anonidk2003 Oh! It’s in our plans, but we haven’t started building yet

@TadashiTech Overleaf is not a math editor…

[Corca @Corca_math]

We stopped writing text on paper years ago. But when it comes to math, we still use it. Not out of love for paper, just because typing math is slow and painful. Corca is as fast as paper, but can also CALCULATE.

[Corca @Corca_math]

@Junda_Chen_ Working on this!

[Corca @Corca_math]

@AlveSvaren It is

@boozy109757600 Open brackets { than click shift+enter for multi-line equations

@Hft_freedom Yes
