GoodExts

GoodExts is an independent collection of free Google Chrome extensions and practical tools built for people who spend their working day on X (Twitter) and in AI-assisted workflows. It is maintained by indie developer wangsen2020 and is aimed at solo founders, developers and operations teams. Extensions: X Video Downloader saves videos from X posts. X Article to PDF exports long X articles to clean PDFs. X Blocker helps detect and manage unwanted timeline content. XZoom (open source) zooms photos and reads tall screenshots in-page. Each works independently. AgentRelay is a free Windows 10/11 service that runs on your own computer and connects compatible extensions, apps and web workflows to the AI clients you already use (Codex, Grok Bot, Antigravity), so you don't need a separate API key in every tool. XFollower is a workspace extension integrating with AgentRelay for AI-assisted X operations. Available in English, Chinese, Portuguese and Spanish.
