About

Take back your X/Twitter feed with AI-powered filtering. Cocoon lets you define what matters to you—and hides everything else.


⚙️ HOW IT WORKS

1. Define Your Interests
Tell Cocoon what you want to see (AI, coding, music production, etc.) and what to block (clickbait, drama, ads).

2. AI Filters Everything
Every post flows through AI analysis. Signal goes to your feed. Noise disappears.

3. See What You Filter
Complete transparency. Know exactly what gets hidden, what you keep, and how much time you save.


🛡️ WHY COCOON

• Your feed, your rules — Not the algorithm's
• Privacy-first — No tracking, no telemetry, all processing uses your own API key
• Aggressive filtering — Designed to protect your attention, not maximize engagement
• Free to start — Extension is free, you just pay for your own AI API usage


🔑 REQUIREMENTS

You'll need an OpenRouter API key (free to create at openrouter.ai). This gives you full control and transparency over what data is processed.


📊 STATS

Typical users see ~80% of posts hidden, keeping only the 20% that match their interests. That's about 4 hours saved per week.


🔒 PRIVACY

Cocoon collects zero data. All filtering happens using your own API key. No analytics, no tracking, no servers. See our full privacy policy at cocoon.surf/privacy

Built for people who value their attention.
