Your file contents never leave your browser

Tinker opens, edits and saves your file entirely on your device. There's no server to trust, no account to make — the free editor even works offline.

Everything you need to tweak. All free.

The full editor is the free tier — not a preview of it.

Click anything, edit it

Text, colors, spacing, images, links. If you can see it, you can change it.

What you see is what you download

The preview runs your real file — scripts and all. No surprises after export.

Add ready-made blocks

Buttons, cards, heros — built to drop in cleanly without breaking your layout.

Code mode, only if you want it

Everything works visually. The HTML is one click away for the curious — never required.

Questions, answered.

The short version: it's free, it's local, and it just works.

How do I edit an HTML file from ChatGPT or Claude without coding?+

Drop the HTML file into Tinker's editor, click the element you want to change, and edit its text, colors, spacing or images directly on the page. When it looks right, download the result as a single HTML file. The whole loop runs in your browser, takes under a minute, and requires no sign-up and no code.

Is Tinker really free?+

Yes — Tinker's editor is completely free and requires no account. Everything you need to edit an HTML file is included forever: visual editing, the component library, code mode, and downloading the finished file. A paid tier is planned for optional cloud extras like saved projects and share links, but the local editor itself stays free.

Does Tinker upload my HTML file to a server?+

No. Tinker never uploads your file. The file is opened directly in your browser, every edit happens on your device, and the result is saved back to your computer as a download. File contents are never transmitted to a server, and the editor keeps working even when you're offline.

Do I need to know HTML or CSS to use Tinker?+

No coding knowledge is needed. Tinker is a visual editor: you click any element on the page — a headline, a button, an image — and change its text, color, size, spacing or picture with simple controls. An optional code mode shows the underlying HTML for those who want it, but it is never required.

What files does Tinker work with?+

Tinker works with any single, self-contained HTML file — the kind produced by AI tools such as Claude, ChatGPT, Gemini or Copilot, including artifacts, reports, landing pages and dashboards. Embedded styles, scripts, charts and images all keep working, both in the live preview and in the downloaded file.

Will my HTML file still work after I edit it?+

Yes. Tinker exports one self-contained HTML file that looks exactly like the live preview you edited. Replaced images are embedded directly into the file, so you can email it, host it or share it and it renders the same everywhere.

What happens if I close the tab while editing?+

Your work is safe. Tinker autosaves your edits to your browser's local storage as you work. When you return, the editor offers to restore the session exactly where you left off — or you can discard it and start fresh. Autosaves stay on your device, like everything else.

Open your file. Start editing.

It's free, it's private, and you'll be changing things in under a minute.
