GoodExts

Free Chrome extensions for X, plus a local AI bridge

Visit

GoodExts is an independent collection of free Google Chrome extensions and practical tools for people who spend their day on X (Twitter) and in AI-assisted workflows, built by indie developer Wang Sen for solo founders, developers and social media teams. X Video Downloader saves videos from X posts. X Article to PDF exports long X articles to clean PDFs. X Blocker detects and hides unwanted timeline content. XZoom (open source) zooms photos and reads tall screenshots in place. AgentRelay is a free Windows 10/11 local service that connects compatible extensions, apps and web workflows to the AI clients you already use (Codex, Grok Bot, Antigravity). Available in English, Chinese, Portuguese and Spanish.

Hi! I'm Wang Sen, an indie developer. I built GoodExts because I spend all day on X and kept needing small, focused tools: saving videos, exporting long articles to PDF, zooming images, and blocking noise. Everything is free. AgentRelay lets these tools reuse the AI subscription you already have (Codex, Grok Bot, Antigravity) instead of separate API keys. Feedback welcome!
