nct — ntoola in your terminal

A single static binary that opens an interactive TUI. Paste content, pick a target format from the menu (PDF, Word, Excel, OCR, and more), press Ctrl+ O, and get the output file in the current directory. Fully offline, zero uploads.

Quick install

Zero dependencies

Single static binary. No Node, no Python, no glibc gymnastics — works in scratch containers and locked-down CI.

Open source

MIT-licensed core. Contribute engines, ship your own build, or embed nct as a library.

Scriptable + interactive

Use the TUI for one-offs; use flags in CI. Exit codes are stable and documented.
