Local-firstYour text never leaves your browser. No upload, no account, no server.
Most online text tools send whatever you paste to a server, run the work there, and send a result back. Your words sit in someone else’s logs, backups and databases, and you have to trust a privacy policy.
Local-first means the opposite: the whole tool is downloaded to your browser and runs on your own device. Nothing you type is transmitted anywhere — not to us, not to anyone. There is no server that could receive it, which is a stronger guarantee than a promise not to look.
Three consequences worth knowing:
Type or paste Markdown on the left and the rendered HTML appears on the right as you type. Tables, task lists, strikethrough, and fenced code blocks all work. Copy the HTML to your clipboard, or download a complete standalone page with styling already inlined. The conversion runs in your browser, so drafts of unpublished writing are never sent anywhere.
CommonMark plus the GitHub extensions people actually use: tables, task lists, strikethrough, fenced code blocks, and automatic linking of bare URLs.
Safe HTML is preserved. Scripts, iframes, inline event handlers, and javascript: links are stripped from both the preview and the exported file, because an exported page often ends up open in someone else’s browser.
Copy gives you the HTML fragment — the body content on its own, ready to paste into an existing page. Download gives you a complete standalone .html document with a doctype, a title, and minimal styling already inlined.
