The capybara sat down at the typewriter. When it stood up, there was a thesis.

Turn handwritten notes, scanned textbooks, and raw data into publication-ready LaTeX -- without knowing a single LaTeX command.

27 templates · 27 automation scripts · 26 reference guides · 4 OCR profiles · 217 tests · 0 LaTeX commands required

The 10-Second Pitch

You describe a document in plain English. This skill produces a compiled PDF.

• An 80-page handwritten math PDF becomes color-coded lecture notes with proper equations and TikZ diagrams.
• A 162-page textbook becomes a 2-page cheat sheet.
• A CSV becomes nine chart types.
• A one-line prompt becomes a thesis, a resume, a conference poster, or a 37-page book with drop caps.

No LaTeX knowledge required. The capybara handles the semicolons.

What Can It Actually Do?

(Spoiler: more than most humans with a PhD in LaTeX.)

You say...	What happens under the hood
"Create my resume"	Selects from 5 ATS-optimized templates, compiles with pdflatex, generates PDF + PNG preview
"Convert my 80-page handwritten math notes into beautiful LaTeX"	pdf_to_images.sh renders at 200 DPI -> batch-7 parallel OCR agents -> math-notes.md profile generates colored tcolorbox theorems (blue), definitions (green), examples (orange) -> compile_latex.sh runs multi-pass pdflatex -> polished PDF with proper equations, proofs, and TikZ diagrams
"Turn this 162-page scan into a 2-page cheat sheet"	pdf_to_images.sh splits PDF -> vision OCR per page -> extracts key content -> symbol substitution -> telegram-style compression -> fits into cheatsheet.tex with 3-column landscape 7pt layout
"Build a quarterly report with charts"	generate_chart.py creates bar/line/pie charts from JSON/CSV -> csv_to_latex.py converts data into booktabs tables -> Mermaid/TikZ flowcharts compiled inline -> all embedded in report.tex with TOC
"Generate 9 charts from my sales CSV"	generate_chart.py reads CSV -> outputs bar, line, scatter, pie, heatmap, box, histogram, area, radar charts -> multi-series, legends, colorblind-safe Tol palette
"Convert my old PDF to LaTeX"	Pages split at 200 DPI -> parallel OCR agents -> clean .tex with profile-tuned formatting -> 0 errors per 7-page batch (validated on 115-page PDF)
"Send personalized letters to 500 candidates"	mail_merge.py loads template + CSV -> Jinja2 rendering -> 4 parallel pdflatex workers -> qpdf --pages merge into single PDF
"What changed between v1 and v2 of my thesis?"	latex_diff.sh runs latexdiff -> highlighted change-tracked PDF with additions in blue, deletions in red
"Make a NeurIPS poster"	Interactive: asks orientation -> layout -> color scheme -> generates A0 tikzposter with correct dimensions and QR codes
"Create a calculus final exam with answer key"	exam class with \printanswers toggle, grading table, 6 question types (MCQ, T/F, fill-blank, matching, short, essay)
"Fetch BibTeX for these DOIs"	fetch_bibtex.sh hits doi.org with Accept: application/x-bibtex header -> appends to .bib -> cross-refs every \cite{} key
"Password-protect this report"	pdf_encrypt.sh applies AES-256 with print/modify restrictions
"Fill this PDF form with my data"	Detects fillable fields -> validates -> fills text, checkbox, radio, choice fields -> completed PDF
"Fill this non-fillable PDF application"	Renders pages -> visual analysis to identify fields -> bounding box validation -> FreeText annotations at precise positions
"Check if my paper is ready to submit"	Verifies packages -> cross-refs citations -> counts figures/tables/equations -> runs chktex for style issues

Template Gallery -- 27 Templates

Every template has been compiled, tested, and verified to produce zero errors. The capybara is a perfectionist.

Resumes -- 5 ATS-Optimized + 1 Legacy

All 5 modern templates designed to pass Applicant Tracking Systems (no columns, no tables for layout, no graphics in header, machine-readable text):

Template	Target Role	Key Design Choices
resume-classic-ats.tex	Finance, law, government	Single-column, minimal styling, maximum parsability
resume-modern-professional.tex	Tech, corporate	Clean sections, subtle color accents
resume-executive.tex	VP / Director / C-suite	Multi-page, executive summary section
resume-technical.tex	Software, data, engineering	Skills matrix, project highlights
resume-entry-level.tex	New graduates	Education-first, coursework, activities
resume.tex (legacy)	Regions requiring photos	Photo area -- not ATS-compatible

Classic ATS	Modern Professional	Executive (p1)	Executive (p2)
Technical	Entry-Level
