A social network built around relevance.
Find the people, content, events, and communities that actually matter to you.
You shouldn't have to follow hundreds of accounts, know exactly who to search for, or wait for something to become popular before you discover it.
- Follow more accounts
- Scroll through noise
- Hope something is relevant
- Tell Cosine what matters
- Discover what's relevant
- Your feed works from day one
One interest unlocks an entire world:
People
Find people who share your interests, goals, and intent.
Content
Discover posts and conversations that are actually relevant to you.
Events
Find events that match your interests, from meetups to global gatherings.
Communities
Find communities around the things you care about, niche or local.
Search for what you mean.
You don't always know who or what you're looking for. Describe it naturally — and Cosine finds it.
Examples:
You don't need exact usernames or job titles. Just describe what you're looking for.
You don't need followers
to be discovered.
On traditional platforms, distribution starts with your existing audience. Cosine takes a different approach: when you create something valuable, it reaches people who actually care — even if you have 0 followers.
A social network that gets better as you use it.
Every interaction gives Cosine another signal about what matters to you. Your interests evolve. Your feed evolves.
Instant Relevance
Connect with people who care about exactly what you care about. No filtering through viral noise.
Your Interests, Your Feed
You tell Cosine what you care about. Your feed surfaces what's relevant — not what's trending.
Stays Fresh
As your interests change, so does your feed. Automatically. No rebuilding required.
Multi-Dimensional You
You're not just one thing. You're Developer + AI + startups + anime + gaming. Cosine understands all of it.
Discover Beyond Your Social Graph
Find people, content, events, and communities based on what actually interests you — inside or outside your network.
Pure Signal
No engagement traps or viral bait. Content is ordered by how well it matches your interests.
Your feed. Your lens.
Switch perspectives effortlessly: surface what matches your interests, what's happening right now, or what's gaining momentum.
You control how you discover.
Your audience doesn't
have to come first.
You don't need 10 → 100 → 1,000 → 10,000 followers before your work can start reaching people.
Create something valuable. Cosine instantly surfaces it to the exact audience that cares about it.
Relevance powers reach.
For everyone else,
there's less noise.
No algorithm games. No managing noise. Just instant relevance.
Instant signal on day one
Tell Cosine your interests once. Your feed fills with relevant content immediately.
No chasing viral posts
Your discovery is powered by interest match, not what's trending in someone else's feed.
No endless scrolling
Cosine surfaces what's genuinely relevant. Less time searching, more time discovering.
Discovery that evolves with you
As your interests and goals change, Cosine adapts automatically — no manual rebuilding.
The internet is full of things
you'll never find.
The problem is finding them.
