Output
Guides
Build a ready-to-paste <textarea> — set the name, placeholder, default content, size, and validation, then copy the generated HTML.
Runs entirely in your browser: no AI call, no credits, no network round-trip. The output updates instantly as you type.
How to use it
- Set the Name, Placeholder, and any Default Content.
- Adjust the size (columns/rows) and validation (min/max length) in Settings.
- Copy or download the generated HTML.
Why is there no live preview?
The output is real, unsanitized form markup — rendering it directly on the page isn't safe. Paste the code into your own page to see it in context.
