Handwriting, screenshots and PDFs into LaTeX you can actually edit.
OCR, a real editor, a diagram builder, an AI pair, collaboration, and an API, all sharing one document model.
e^{i\pi} + 1 = 0Photograph a whiteboard, drag in a screenshot, or scan a page of handwriting. You get LaTeX that compiles, not a description of it.
Pull equations, tables and structure out of a paper and keep working with them.
Drag nodes, draw edges, get TikZ. Plus a browsable library of working examples.
Fix a compile error, restructure a proof, or generate a figure. Every edit arrives as a diff you accept or reject, line by line.
A CRDT underneath, so two people in the same paragraph converge instead of overwriting each other, and it survives a dropped connection.

MIT licensed, self-hostable, with a REST API for the rest of your pipeline.
Three steps, one document, no exporting between four different tools to get there.
Snip a photo, upload a PDF, or start from a blank document. Recognition runs in seconds and hands back source, not an image.
A real editor: syntax highlighting, autocomplete across thousands of commands, live preview, and SyncTeX jump-to-source.
Compile to PDF, export the project as a ZIP, or pull it through the API. Nothing is locked in. It was always just .tex files.
Overleaf edits but cannot read your handwriting. Mathpix reads it but cannot edit. TeXeR is the overlap.
