Slop Blocker

Local-first browser extension that filters bots, AI-generated replies, and keyword-matched content on Twitter/X.

Slop Blocker automatically hides bot replies, AI-generated spam, and engagement-farming comments in your Twitter/X feed so you see real conversations, not noise. WHAT IT DOES • Scores every reply using multiple signals: suspicious username patterns, missing profile pictures, link spam, and engagement-farming phrases • Optionally routes ambiguous replies to an AI judge via your own API key (BYOK). No data ever touches our servers • Soft-hides replies with a "show anyway" option. No reply is permanently deleted • Shows a reason for every hidden reply so you know exactly why it was filtered WHY IT'S DIFFERENT • 100% open source (MIT). Review every line at github.com/mx-92x/slop-blocker • Local-first: no account, no backend, no telemetry. Everything runs in your browser • Fully tunable: adjust scoring thresholds with sliders in the popup • BYOK (Bring Your Own Key): optionally connect OpenAI, Anthropic, DeepSeek, Groq, Mistral, or any OpenAI-compatible endpoint PRIVACY All filtering happens on your device. If you use BYOK, your text goes directly to your chosen provider. Slop Blocker never sees it. API keys are encrypted with AES-GCM before storage. KEYBOARD SHORTCUT Ctrl+Shift+X (Cmd+Shift+X on Mac) toggles filtering on/off instantly.
