Heat equation, steady state

∂u/∂t = α · ∇²u,   with   u(x, 0) = f(x)

0 ex² dx = √π / 2

The gap

Overleaf charges $21/month for track changes. We just ship it.

Built for problem sets, not packages.

Everything you need to write, share, and export a math document — and nothing you'd need a Stack Overflow tab for.

Visual equation editor

Click symbols, fractions, integrals. Build expressions the way you'd write them on paper.

5 collaborators on free

Overleaf gives you one. We start at five — because group problem sets aren't solo work.

Full document history

Every keystroke versioned. Restore any draft. No paywalled track changes.

PDF export

One click to a paper-ready PDF with proper math typesetting. No compile errors.

No setup

Open a tab, start writing. No packages, no preamble, no \usepackage{amsmath}.

Works everywhere

Browser-first. Same document on your laptop in lecture and your phone on the bus.

Two plans. One is $9.

No seat tiers, no academic discount theatre, no "contact us." Cancel from the dashboard.
