FilterX

FilterX is a content detector tool. A browser extension for Chrome, Firefox, Edge, Opera and Safari that hides social posts matching keywords or expressions you define, with prompt-based AI filtering sold as a preorder and not yet live.

FilterX is a browser extension that removes unwanted posts from your social feeds before you have to read them. The pitch on the site is blunt: focus on your growth and filter out everything else. The main demonstration targets LinkedIn-style spam, the generic connection requests from remote workers, startup networks and recruiter accounts that flood a timeline with near identical "let's connect" posts. Rather than muting individual authors one at a time, FilterX works at the level of content, matching words and expressions you specify and hiding any post that contains them. The current free tier is deliberately simple. You install the extension on Chrome, Firefox, Edge, Opera or Safari, spend about a minute on a no-code setup, and enter the words or phrases you never want to see again. The site claims you can filter out any word or expression, and it also advertises context-aware filtering, which suggests the matching goes beyond a naive substring check. That matters in practice: a keyword like "connect" would otherwise wipe out legitimate posts, so context handling is what makes a broad filter usable. The second layer is AI filtering. This is not available yet. The site lists it as coming soon and sells a discounted preorder at $4.99 that locks in the price before it rises to $12.99 at launch. AI filtering is described as filtering with prompts, so the intention is presumably to hide posts by theme or intent rather than by literal string match. Context-aware filtering is mentioned as part of the free product and also as part of the paid bundle, so check the FAQ before paying for what may already be included. This is a narrow utility, and that is its appeal. It sits closer to a feed hygiene tool than to a full moderation platform, so anyone hoping to moderate a community they run will need something else. The realistic buyer is an individual professional who wants a quieter timeline without unfollowing useful people.
