Signal — AI filters for your X timeline

Describe what you don’t want to see on X. Signal hides matching posts and keeps the ones worth reading.

Signal lets you describe what you don’t want to see on X in plain words, and quietly hides matching posts from your timeline. Type “AI hype with no substance”, “crypto shilling”, “NBA playoff spoilers” or “engagement bait threads” — Signal turns each sentence into a filter and checks posts as you scroll. Posts that match fold into a small “Post hidden” marker that tells you which filter caught them. One click shows the post again. • Filters in your own words. No keyword lists to maintain. • Keeps the good stuff. Filters are built to hide empty hype while keeping measurements, analysis and honest criticism. • Hidden, not gone. Every hidden post leaves a marker with the reason. Reveal one, or show them all in place. • Learns from you. Choose “Less like this” in any post’s ··· menu and tell Signal why. • Adjustable strength. Gentle, Balanced or Strong per filter. • Ready-made filters for AI slop, ads and engagement bait. • Exact keywords and phrases, checked on your device. • Works on Home, replies, search, profiles and lists. Free, no account or API key needed. Classification is powered by Jev, TypeSafe’s fast classification model. Privacy: when AI filters are on, the text of posts in your timeline and your filter descriptions are sent to Signal’s service for classification. Signal never reads images, your account details or pages outside X. Full policy: https://signal.agenturl.dev/privacy
