Hyperclay: Where your team's HTML files belong

Hyperclay launched HTML Clay, a free desktop app for macOS, Windows, and Linux that opens .htmlclay files in a normal browser tab and saves edits back to the file on disk, with every version kept as a backup. Hyperclay positions the product as a Google Drive and Notion alternative where dashboards, reports, and plans remain plain HTML files that AI coding tools such as Claude Code, Codex, and Cursor can edit directly while the open page updates live. A team workspace adds shared files, revocable secret edit links, zero-refresh sync, an auto-generated sidebar CMS, and targeted AI block edits triggered with Cmd+J.

One home for the dashboards, reports, and plans you already generate. Your team and AI tools already create rich HTML dashboards, visual plans, and calculators because HTML looks great in any browser and stays interactive. Even working solo, those files pile up in Downloads folders, chat threads, and email attachments where nobody finds the current version twice. Hyperclay gives those files a real workspace, locally on your computer or online with your team. Start free on your computer. Bring your team when you are ready.
