What is Constly?

Constly is a WYSIWYG Markdown editor for macOS, Windows and Linux. It renders Markdown inline as you type - headings, bold, lists, tables, KaTeX math and Mermaid diagrams all appear in place, with the raw marks showing only where your cursor is. It's built on byte-fidelity: plain text is the document and the view is just a projection, so saving touches only the bytes you changed and never reflows or "normalizes" Markdown you didn't edit - your git diffs stay clean.

Free to use with no feature wall, watermark or expiry. After two weeks a weekly reminder says hello, and a one-time $19.99 license (up to 3 devices) retires it. Nothing checks and nothing stops you - if it earns its keep, especially at work, buy one. Native (Rust core, tiny footprint), private by default (no account, no telemetry, remote images gated), fully offline - with Vim mode, focus and typewriter modes, a command palette, local version history, and export to HTML, PDF, Word, ODT, RTF, LaTeX and EPUB.
