Pdf To Tns File Converter
Feature: PDF → TNS File Converter
Implementation considerations
- Client-side: PDF.js for rendering, PDF-lib for manipulation, Tesseract.js for OCR, MathJax/LaTeX parser for rendering math, wasm-based packager to build .tns.
- Server-side: containerized workers for heavy processing, optional MathPix or custom ML model for math OCR, S3-compatible storage for temp files.
- Library for .tns creation: implement spec or adapt existing open-source tools that can write TI‑Nspire document packages.
Alternative A: Use a Smartphone Bridge
- Keep PDFs on your phone. Use the TI-Nspire CX App (iOS/Android) to view native TNS files synced via cloud. Not a true converter, but lets you reference PDFs alongside calculator work.
