tweeks

Tweeks is a Chrome extension from Y Combinator's latest batch that lets you customize any website using plain English. Instead of writing custom JavaScript and CSS like you would with Tampermonkey, you just describe what you want in natural language and it generates and applies the changes for you.

The founders, Jason and Matt, built it because the modern web is cluttered with banners, modals, ads, and recommendations you didn't ask for. You can hide sidebars on Twitter, remove YouTube recommendations, add dark mode to any site, or filter social media feeds by date and engagement.

It sits in the middle ground between building your own website and using an AI agent to browse for you. Most of our time online is spent on other people's sites, and Tweeks lets you reshape them to work how you want. You can share your tweaks with others or browse what the community has made.

Example Prompt:
"Always hide YouTube "Shorts" section. Also hide the Shorts button in the left sidebar"
