Imbue open‑sources Bouncer

Imbue has open-sourced Bouncer, a browser tool that filters posts out of a user’s X feed based on plain-language instructions instead of X’s default ranking. (github.com) The public repository appeared on GitHub within the past day, and Imbue’s product page dated April 8 says Bouncer is live now as a Chrome extension and as an iPhone app. (github.com) (imbue.com) (apps.apple.com) Bouncer asks people to describe what they do not want to see with prompts like “crypto,” “engagement bait,” or “rage politics,” then classifies and hides matching posts in real time. The GitHub readme also lists image-aware filtering and a review panel that shows why a post was filtered. (github.com) The basic idea is closer to a personal spam filter than a new social network. Instead of changing what X serves to everyone, the extension watches the feed in the browser, checks each post against user-defined topics, and fades matching posts out of view. (github.com 1) (github.com 2) Imbue says the tool is meant to shift control from platform algorithms to end users at a moment when many people rely on X for breaking news, politics, and local updates but do not want the full “For You” mix. Its April 8 post says Bouncer can also “gently retrain” the feed by reducing time spent on filtered posts over a day or two. (imbue.com) The codebase shows how that works. A MutationObserver scans X for new posts, extracts text, images, and metadata through a Twitter adapter, sends them to a selected model for classification, caches the result, and hides anything that matches the user’s filters. (github.com) Imbue says users can run models locally through WebLLM and WebGPU, or connect cloud providers including OpenAI, Google Gemini, Anthropic, and OpenRouter. The readme lists local support for Qwen3-4B, Qwen3.5-4B, and Qwen3.5-4B Vision, while Imbue’s product post says the company is currently serving Qwen 3.5 4B from its own data center as it works toward running more of the system on laptops and phones. (github.com) (imbue.com) The repository already includes manifests for Chrome, Firefox, and Safari desktop, but Imbue says current support is limited to Twitter’s feed in Chrome and iPhone, with Reddit, LinkedIn, Safari, and Firefox planned next. (github.com) (imbue.com) Bouncer is arriving into a crowded ecosystem of X customization tools, but most older extensions change layout, hide interface elements, or mute exact words. Imbue is betting that an open repository and a filter that understands tone and context will persuade users to hand feed curation to their own software instead of the platform’s algorithm.
