EQUATIONS.TEX
% source: lecture-07.png

What you get
check_circleOne documented LaTeX block per equation

check_circlePrinted equation numbers preserved as labels
check_circleUnclear symbols flagged, never silently guessed

How it works
1Upload images, PDFs, or a zipScreenshots, scanned pages, or photos — phone shots of a whiteboard are fine.
2Equations read page by pageOur vision models transcribe every display equation, matrix, and aligned system faithfully, flagging unclear symbols instead of guessing.
3Parse-checked LaTeX, three waysA documented .tex file, a one-per-line .txt for quick copy-paste, and a CSV with source, label, and validation status.
Who uses this tool
The same file, different jobs. Tap a prompt to try it.
ACADEMIC WRITING
Cite equations from scanned papers
Pull the equations out of an old scanned PDF as LaTeX ready to paste into your manuscript.
STUDENTS
Lecture slides into your notes
Screenshot the slide, get the LaTeX — matrices, cases, and aligned derivations included.
RESEARCHERS
Rebuild a bibliography of formulas
Zip a folder of equation screenshots and get one validated .tex file back.
TEXTBOOK AUTHORS
Modernize old typeset material
Photograph pages from out-of-print books and get amsmath you can actually compile.
TUTORS & TEACHERS
Worksheets from whiteboard photos
Board work becomes clean LaTeX for handouts, with unclear symbols flagged for review.
PUBLISHING
Proof against the original
Nothing is silently repaired — expressions that fail to parse are kept and flagged with the error.
SECURITY
Built for sensitive documents
Bank statements, medical files, case records. Security isn't a feature we added — it's the foundation.
lock
Encrypted in transit
Encrypted in transit over TLS 1.2+, and stored in access-controlled, encrypted object storage. Files are protected the moment they leave your browser.
admin_panel_settings
Your files stay yours
Workspaces are isolated per account. Role-based access shows teammates only what they need.
auto_delete
Deleted, not stored
Files are deleted after processing. Everything runs on our own hardware and is never sent to an outside AI service, so your data is never used to train models.

Questions
Every expression is parse-checked with a real LaTeX math parser before you download it. Valid equations are marked valid; anything that fails is kept verbatim and flagged with the exact parse error, so nothing is silently dropped or repaired.
Yes — matrices (pmatrix, bmatrix, vmatrix), piecewise cases, arrays, and aligned multi-line systems all come back as standard amsmath environments that work inside math mode.
The model picks the most plausible reading and adds a % uncertain comment naming the alternatives, which is also surfaced in the CSV notes column — you review it instead of discovering a wrong subscript at submission time.
