Kavel is a free AI video generator and AI image generator — 4K clips with sound, and images you can run without an account or a card. This userscript brings the image side to every page you read.
What it does
Select any sentence on any web page, click the 🎨 Image button that appears next to it, and an AI image built from that text shows up in place, ready to save. No API key, no sign-up, nothing to configure.
- Input: any text you select, or a prompt typed into the menu command Generate an image from a prompt… (works without a selection).
- Output: one image, shown in a floating card with a download link.
- Time: usually well under a minute.
- Where it runs: every site (Tampermonkey, Violentmonkey, ScriptCat).
Free tier
The script calls Kavel's anonymous free tier: 1K output with a watermark and a small daily allowance per machine. Want more poses for a character you just generated? The AI pose changer on Kavel re-poses the same person from one photo.
Permissions
GM_xmlhttpRequest to www.kavel.ai only, to send the prompt and fetch the finished image. Nothing else leaves the page.
