Bubbletoday

bubble.today is a private link discovery tool for people who trust each other's taste.

You and your friends are already reading interesting things. bubble surfaces those intersections — the articles, tools, and pages that multiple people in your group visited — without anyone having to share anything deliberately.

How it works
The extension quietly tracks the pages you visit and sends only a cryptographic hash to the server — your actual URL is never transmitted until at least one other person in your group visits the same page. When that threshold is crossed, the link is revealed to the group. This is called commit-reveal privacy: you commit to having visited something before you're willing to reveal it.

What you get
• A live feed of links your bubble members are collectively reading
• Trending alerts when a page is gaining traction in your group
• A self-growing AI wiki that synthesizes everything your group reads into a shared knowledge base
• A personal wiki built from your own browsing — private to you
• Full control over which domains are tracked or blocked

Built for trust, not growth
There's no public feed, no follower count, no viral loop. You join small groups of people you actually know. Your group memberships can be kept private. You can leave any group at any time and your data goes with you.
