Customaise

Your AI-powered userscript manager

Why are you fighting your own browser? You spend hours scrolling past bad layouts, clicking the same buttons, and suffering interfaces you can't change. Customaise fixes that. Tell it what you want in plain English (or any language you prefer) and an autonomous AI agent writes, tests, and deploys a script that runs locally in your browser. No coding required. 🤖 AI That Actually Works Customaise is powered by a Gemini AI agent that: • Plans, writes, tests, and deploys code for you • Sees your page structure and self-corrects on failure • Explains what your code does, so you learn as you go • Supports 50+ languages, so you can describe changes in your own words ⚡ Solve Everyday Frustrations ✅ Click Autopilot: turn 47 daily clicks into one ✅ Data Liberation: that table with no export? Now it has one ✅ Instant Prototype: show stakeholders the fix, not a slide deck ✅ Keyboard First: add hotkeys to tools that forgot them ✅ Restyle anything: hide distractions, add dark modes, fix layouts 🔒 Zero Risk. Infinite Undo. We never touch the site's source code. Your changes float in a safe layer above the page. Messed up? Slide the timeline back.
