#cli

Reflow plain text to a fixed column width on word boundaries — the classic word-wrap you need for terminal and CLI output, email and plain-text formatting, code comments, README and changelog blocks, and fixed-width reports. The wrap endpoint breaks text to a chosen width while preserving paragraphs (blank-line separated), with optional left indentation and the option to hard-break words longer than the line; the unwrap endpoint does the reverse, collapsing a wrapped block back into single-line paragraphs. Pure local computation — no key, no third-party service, instant; up to 200,000 characters via POST. Live, nothing stored. 3 endpoints. Distinct from case conversion, slugs and text statistics.

Turn text into ASCII-art banners as an API, with 300+ classic FIGlet fonts (Standard, Slant, Big, Ghost, Doom, 3D-ASCII, Banner and many more). Send a word or short phrase and a font and get back ready-to-paste ASCII art, with control over output width and the letter-spacing layout. Browse and search the full font catalogue. Rendering runs entirely on the engine — no third-party service, so it is fast and always available. Ideal for CLI tools and terminal output, README and changelog headers, build banners, chat and Discord bots, retro UIs and any place a plain string deserves a little flourish.

Simplified, example-driven help for the command line as an API — the community tldr-pages project, 7,045 command-line tools across Linux, macOS, Windows and more. Instead of dense man pages, every command (tar, git, ffmpeg, curl, docker, ssh, awk, …) comes back as a short description plus a handful of practical, copy-paste example commands with placeholders. Look up a command, search commands by name or description, filter by platform, or fetch a random command. Ideal for terminals, IDEs, chatbots, developer tools, onboarding and learning.
