Is recognition really on-device?
Yes. The optional free model and runtime are downloaded to your browser. The formula image is used for local inference, not submitted to an API. Models are large and may not work on every device.
Upload or draw a formula, select its boundaries, and turn it into LaTeX with optional local AI. Correct every symbol, preview typeset notation, and export the math you need.
1. Import or draw 2. Select expression 3. Recognize 4. Edit & export
Start with a file, freehand drawing, or the sample.
Select an equation to review it and export.
Equations will appear here. You can also add a blank LaTeX equation without an image.
Yes. The optional free model and runtime are downloaded to your browser. The formula image is used for local inference, not submitted to an API. Models are large and may not work on every device.
Yes. Drawing, crop selection, LaTeX editing, MathML conversion, SVG/PNG exports and project save/reopen work without recognition downloads.
It varies with symbols, handwriting clarity and formula length. Always correct the text before using it in assignments or papers.
Each image can contain several formulas, but select each expression separately. This is not a full textbook or PDF layout recognizer.
Working on your equations locally…
Import an image, draw ink or enter LaTeX manually. Select an equation region, optionally recognize it and correct every symbol before preview/export. Save the project to preserve images, equations and editable strokes.
Recognition downloads model/runtime assets and needs review; it is not equation solving or proof of mathematical correctness. The specialized handwritten model remains disabled pending licensing review. No PDF/full-page layout recognition is supplied. MathJax renders supported notation locally; image/equation/stroke/project budgets and undo-scope limits apply. Projects embed potentially sensitive source images.

Import an image, draw ink or enter LaTeX manually, select one equation region and optionally request TexTeller recognition. Correct the recognized symbols, inspect the bundled MathJax preview, and export supported TeX, MathML, SVG, PNG or project files.
Authored example: Use an expression containing a fraction and a superscript. Verify the numerator, denominator and exponent one by one; a clean preview only shows that MathJax rendered the entered notation.
Limits and model handling: TexTeller runtime/model assets download for recognition; MathJax preview is bundled locally. Recognition is not equation solving or proof of mathematical correctness. Select expressions individually rather than expecting full-page textbook layout recognition. The specialized handwritten model remains disabled pending licensing review. Projects embed source images and are subject to image, equation, stroke and project budgets.
No. It proposes notation from an image region. Correct the symbols and independently verify any mathematical result.
No. Select individual equation regions. It is not a full-page PDF or textbook layout recognizer, and the specialized handwritten model remains disabled.
