Manifold\frac{1}{3}1/3\sum_{n=1}^\inftyΣFormulas as you type them
Type LaTeX or press the keys you already know. The formula draws itself in place, and the caret moves through it the way you expect it to.
A document editor for mathematics
Write the mathematics.The typesetting follows.
Formulas render as you type them, Hebrew and English share a paragraph, and the PDF is the page you were looking at.

1The fundamental theorem
Let f be continuous on [a,b] and let F be an antiderivative of f. Then
∫ f(x) dx = F(b) − F(a)(1)
ולכן, עבור f(x)=x^2 על הקטע [0,1], השטח שמתחת לגרף הוא 1/3.

The usual choice
LaTeX editors show you the formula. Manifold shows you the page.
Writing LaTeX, by hand or in a structured editor, you see the formula or its source — but whether it fits between the margins, where a line ends and where a page breaks are things the PDF tells you afterwards. Manifold lays out the real page while you write, and the PDF is that page.
In a LaTeX editor
The formula looked right while you wrote it. The PDF puts it past the margin, and the log says by how much.
In Manifold
It breaks after a relation where it meets the margin, while you type it, and the PDF is the same page.
What it does
Built for papers that have formulas in them.
Every x has a unique closest point in a closed subspace M.
לכל x יש נקודה קרובה ביותר יחידה בתת־מרחב סגור M.
Two languages in one paragraph
Each paragraph takes its direction from its own first words, Hebrew and English can share a sentence, and every formula reads left to right. There is no switch to set.
Real pages, and the PDF is them
Margins, numbered equations and footnotes at the foot of the page, laid out as you write.

Calculations, worked step by step
Ask for a derivative, an integral or a limit and get the working, each step naming its rule.
Your papers come with you
Your .lyx files open with their layouts, formulas, tables and figures, and your macros and keyboard shortcuts come along.
Hebrew, English and mathematics in one document — the outline following along. This is a recreation of the window, animated.
How it works
From a download to a finished PDF in three steps.
Download and open it
No account, and nothing else to install for writing. Your documents are files on your own disk.
Write
Press Ctrl M for a formula, and choose a section, a theorem or a proof from the list. The numbering takes care of itself.
Export
A PDF that matches the screen, or LaTeX source for anyone who works in LaTeX.

Questions
What people ask before they download.
Is Manifold free?
The editor is free, needs no account, and always will. Keeping documents in your account, sending copies, writing together and the model Manifold hosts are part of a plan, from $10 a month, with a free taste of each.
Do I need to know LaTeX?
No. Structure is chosen from a list and formulas are typed with keys. If you know LaTeX, type it and it renders as you go.
Can I still get LaTeX out of it?
Yes. Export a .tex file whenever you like, with Hebrew handled by XeLaTeX and polyglossia, or export a PDF of the pages on screen.
Will my .lyx files open?
Yes. Layouts, formulas, tables, figures, footnotes and cross references come across, and anything that cannot is named rather than dropped. Your macros and keyboard shortcuts can come along too.
Where are my documents kept?
In a file on your own disk. Nothing you write leaves your computer unless you ask it to.
How well does it handle Hebrew?
Hebrew and English were the starting point. Every paragraph finds its own direction, formulas always read left to right, the interface speaks both languages, and proofreading checks both.
What does it need installed?
Nothing for writing, formulas and LaTeX export. Chromium for PDF export, TeX Live to change a drawing and a local model for writing help are optional: Settings lists what is missing, says what each is for, and installs it for you.
Why does my computer warn me the first time I open it?
The builds are not signed yet, so macOS and Windows ask once. The download page gives the one step that gets past it on each system.
Is there a version for the browser?
Yes. The same editor runs in a tab on a computer, with nothing to install. Phones and tablets are not supported yet.
Free to download, and free to keep writing in.
No account, no trial that runs out, and your files stay on your disk.
