Handwriting and print
Lecture notes, worked solutions, exam papers, whiteboards, and printed textbook pages. Mathematics written by hand is what Ink2TeX is built for.
iPhone · On-device recognition · Real LaTeXHandwritten mathematics,
Handwritten mathematics,
typeset by your iPhone.
Photograph a page of notes, a problem sheet, or a whiteboard. Ink2TeX reads the mathematics on your device and hands back a complete LaTeX document — one you can edit, compile to PDF, and open in Overleaf, without typing a single backslash.

Coming to the App Store
Ink2TeX is in development for iPhone. Join the early-access list and we will write to you once — when it is available to download.
How it worksFrom a photograph
From a photograph
to a document.
Four steps, no retyping. Everything up to the optional cleanup pass happens on the iPhone in your hand.
Photograph the page
Point the camera at a notebook page, a whiteboard, a problem sheet, or a textbook. The guided scanner checks focus, glare, and page edges before it accepts the shot, so the recognizer gets a page worth reading.
The page is read on your device
Apple's Vision text recognition runs on the iPhone itself. Ink2TeX then works out the structure of what it read — headings, paragraphs, numbered lists, display equations, tables, and underlined terms — instead of returning one flat block of text.
You get a real LaTeX document
Sections, equation environments, itemized lists, and tabular blocks are assembled into a complete document with its preamble, not a loose string of symbols. Uncertain readings are marked for you rather than guessed at silently.
Edit, compile, export
Correct anything you like in the built-in LaTeX editor, compile it to a PDF on the phone, and send the .tex and .pdf anywhere — Files, Mail, Messages, or straight into an Overleaf project.
What it doesBuilt for the page
Built for the page
you actually wrote.
Scientific pages are not plain text. Ink2TeX is designed around the things that make them hard — layout, notation, and the symbols recognizers habitually confuse.
Equations as equations
Display formulas become equation environments, fractions stay fractions, and sub- and superscripts survive the trip. Matrices and cases keep their shape.
Structure, not soup
Titles, paragraphs, numbered and bulleted lists, tables, and underlines are detected as separate blocks, and you can correct any block's type before the document is built.
Subject dictionaries
Seven subject vocabularies sharpen recognition where it usually fails — ρ against p, ℓ against l, Σ against E — and rank alternatives instead of overwriting your page.
A LaTeX editor that helps
Syntax highlighting, full undo, and a plain-English error list built from the compiler log, with the line each problem came from.
A PDF, compiled on the phone
A real TeX engine ships inside the app, so your document is typeset on the device — with no server round trip and no TeX distribution to install.
Overleaf in one step
Send the finished source straight into a new Overleaf project when you want to keep working on a laptop, or share the .tex and .pdf through the usual iOS share sheet.
A library of your work
Every scan is saved on the device with its source and equations, searchable, renameable, and recoverable from Trash.
7 subjectsIt knows what
It knows what
you are writing about.
Choose a subject before you scan. Its vocabulary guides the recognizer and the correction engine, so notation is read as notation rather than as ordinary letters.
Mathematics
Limits, integrals, matrices, proofs, set and logic notation.
Physics
Vectors, units, constants, differential equations, field notation.
Chemistry
Reaction arrows, states of matter, organic and physical notation.
Biology
Genetics, molecular and biochemical vocabulary.
Computer science
Algorithms, complexity classes, logic, pseudocode blocks.
Engineering
Circuits, signals, materials and measurement notation.
Statistics
Estimators, distributions, expectation and variance notation.
PrivacyYour notes stay
Your notes stay
your notes.
Unpublished research, a graded exam, a page of someone else’s lecture — the things people scan are not always theirs to upload. Ink2TeX is built so they do not have to be uploaded at all.
01
Photos stay on the phonePage images are recognized on the device. Your scans are never uploaded, and no cloud library holds copies of them.
02
AI polishing is yours to chooseThe optional cleanup pass sends the drafted LaTeX text — never the photograph — to the Ink2TeX service, and only when you ask for it.
03
No document retentionThe service is built to process a request and forget it. Scientific content is not kept for training or analytics unless you explicitly opt in.

Step through the whole flow on a prepared page — camera, recognition, the LaTeX document, the compiled PDF, the export — then tell us in three taps whether you would use it. The web prototype that converts arXiv papers to LaTeX is on the same page.
Ink2TeX FAQQuestions,
Questions,
answered plainly.
What people ask before they scan their first page.
How do I convert handwritten math to LaTeX?
Photograph the page with Ink2TeX, let it recognize the writing on the device, review the blocks it found, and it assembles an editable LaTeX document you can compile, correct, and export. There is no retyping and no symbol palette to hunt through.
Is there an iPhone app that turns handwriting into LaTeX?
Ink2TeX is exactly that: an iPhone app that scans handwritten or printed mathematics and produces a complete LaTeX document, with an editor and a PDF compiler built in.
Does Ink2TeX work offline?
Scanning, text recognition, structure detection, LaTeX generation, editing, and PDF compilation all run on your iPhone and work in airplane mode. Only the optional AI cleanup pass needs a connection.
Can I edit the LaTeX it produces?
Yes. The result opens in a LaTeX editor with syntax highlighting, undo, and a readable list of compiler errors, beside a live PDF preview. Nothing is locked.
Does it really compile a PDF on the phone?
Yes. A TeX engine and a set of standard packages are bundled with the app, so your document is typeset on the device rather than sent to a server to be built.
Can I open the result in Overleaf?
Yes. Ink2TeX hands the finished source to Overleaf as a new project in one step, and you can also share the .tex and .pdf files through the iOS share sheet.
Which subjects does it understand?
Ink2TeX ships with vocabularies for mathematics, physics, chemistry, biology, computer science, engineering, and statistics, plus shared rules for layout and transcription. You pick the subject before scanning and recognition is tuned to it.
Does it work with printed pages as well as handwriting?
Yes. Printed textbook pages, problem sheets, and slides are read the same way — handwriting is simply the harder case the app is designed around.
What happens to my pages and documents?
Page images are processed on the device and are never uploaded. If you use the optional AI cleanup, the drafted LaTeX text is sent to the Ink2TeX service for that request and is not retained for training or analytics unless you opt in.
What will Ink2TeX cost?
The app is free to download, and scanning, recognition, LaTeX generation, editing, PDF compilation, and export do not cost anything. The optional AI cleanup is counted in pages, available through a subscription or as page packs, and pricing is shown in the app before anything is bought.
