People Like You Content For You Grows With You

Math, Not Global Trends.

Your feed is built on how well content matches your specific interests, not what's going viral. No engagement traps, just pure relevance.

Search Ideas, Not Keywords.

Our engine understands the meaning behind your search, connecting you with the exact people and content that keyword filters always miss.

Revisit Your Past Feeds.

Save your feed state and jump back to exactly what you were seeing weeks or months ago. Your curiosity evolves, but you shouldn't lose your history.

Describe Exactly What You're Looking For.

Forget keyword hacking. Tell Cosine what you want to find—like “Cyberpunk architects interested in sustainability”—and we’ll connect you with the specific people and ideas that actually match your curiosity.

Signals

A separate feed for high-value opportunities that bypasses the noise and lands directly with the people who match your interests.

Signals live in a dedicated, opt-in feed. They never interrupt the social flow. Users visit the Signal stream when they are looking for opportunities, meaning your message lands with intent, not interruption.

Open for everyone to browse. Find the opportunities strictly aligned with your interests.

Use Signal Credits to broadcast high-fidelity messages for:

  • Critical Announcements

    Product drops, version releases, and major updates. Ensure your news lands with the people who actually care.

  • Collaboration & Hiring

    Find co-founders, hire niche talent, or recruit beta testers. Target by expertise, not just popularity.

  • Events & Meetups

    From local gatherings to global hackathons. Broadcast your event directly to people that match your theme.

Deterministic Vector Routing

Configure your vector coordinates. Cosine connects you directly to profiles and documents mathematically mapped to your explicit parameters.

Cosine automatically adapts as your interests change, or lets you lock a perfect vibe forever.

No engagement traps or viral bait. Content is ordered solely by how well it actually matches your curiosity.
