Customaise

The web, on your terms. Tell AI what to change on any site. It writes the code, you keep the result.

✨ Customise any website, automate repetitive tasks, and manage userscripts with an AI browser agent. Describe changes in your own words, in any of 21 supported languages. No coding required. Tampermonkey compatible. Why are you still fighting websites that don't work the way you need them to? You spend hours scrolling past bad layouts, clicking the same buttons, and putting up with interfaces you can't change. Most people accept it. Customaise fixes that. Tell the AI what you want, and an autonomous Gemini AI agent writes the code, tests it, and installs it. The change runs automatically every time you visit that page. No coding. No developer tools. No tickets to file. You see a problem, you describe it, it gets fixed. 🛠️ SOLVE REAL PROBLEMS Stop adapting to bad websites. Make them adapt to you. ⚡️ Automate workflows: turn 47 daily clicks into a single action. ⚡️ Add missing features: export buttons for locked tables, hotkeys for tools that forgot them. ⚡️ Fix interfaces: force dark mode, increase font sizes, hide distracting feeds and pop-ups. ⚡️ Extract data: pull information off pages that lock it behind bad UIs. ⚡️ Live prototyping: show stakeholders a working fix in the browser, not a slide deck. 🎯 HOW IT WORKS Three ways to tell the AI what you want, in any of 21 supported languages: 👆 Point and click: Hover over any element on the page and click to select it. The AI understands what you mean and generates the right code. ⌨️ Plain language: Type "hide the sidebar" or "make the font bigger" or "auto-click the confirm button." 🎙️ Voice input: Press the mic and talk. Real-time transcription with a live waveform and auto-restart on silence. 🤖 AUTONOMOUS AI AGENT Customaise is powered by a Gemini AI agent that understands your browser: ✓ Plans multi-step changes before writing code. ✓ Sees your page structure and existing scripts. ✓ Self-corrects when something breaks. ✓ Explains what the code does as you go. ✓ Deploys a Browser Agent that clicks, types, scrolls, and navigates on your behalf. 🛡️ ZERO RISK Your changes float in a safe layer above the page. The site's source code is never touched. ✓ Every edit creates a restore point automatically. ✓ One-click undo to any previous version. 🐒 TAMPERMONKEY COMPATIBLE Already use userscripts? Customaise is a next-generation userscript manager. ✓ One-click import for your existing .user.js files. ✓ Full support for Metadata, @match rules, and GM_* APIs. ✓ Seamless migration from Tampermonkey or Violentmonkey. ☁️ CLOUD SCRIPT SHARING Build once, share anywhere. Manage your scripts from a unified Account Portal. ✓ Publish your scripts to the community and build your portfolio. ✓ Subscribe to tools built by others and receive automatic updates. ✓ Share private install links for team or client distribution. 💻 PROFESSIONAL CODE EDITOR For developers who want full control: the Monaco editor that powers VS Code. Syntax highlighting, validation, and an AI that reads your console errors to debug alongside you. 🔒 PRIVACY FIRST Your data is yours. ✓ We use paid Gemini APIs. Your prompts are never used to train models. ✓ All conversation history is encrypted on your device with a key only you control. ✓ AES-256-GCM encryption with 100,000-iteration key derivation. 🚀 POWER USER UPGRADE (ONE-TIME PURCHASE) No subscriptions.
