Getting Started

LinkBrain is your AI-powered second brain for links. Save anything from the web, then search, organize, and rediscover it with AI.

1. Create Your Account

Sign up at linkbrain.co/signup using one of three methods:

  • Google — One-click sign-in with your Google account
  • Apple — Sign in with Apple (uses your Apple ID, supports Hide My Email)
  • Email — Enter your email for a magic link or set a password

The free tier includes every feature with a limit of 50 saved links. No credit card required.

2. Install the Browser Extension

The fastest way to save links is the Chrome extension. Install it from the Chrome Web Store. On first install, it will offer to import all your Chrome bookmarks automatically.

💡 Tip: Pin the extension to your toolbar for one-click saving. Use ⌘⇧S (Mac) or Ctrl+Shift+S (Windows) to save even faster.

You can save links in multiple ways:

  • Extension — Click the icon or press ⌘⇧S on any page
  • Right-click — Right-click any link → "Save to LinkBrain"
  • Quick Save — Paste a URL into the Quick Save bar in the Library
  • Import — Bring in bookmarks from Chrome, YouTube, Spotify, X, Pocket, and more
  • Omnibox — Type lb in your address bar to search your library
  • API — Save programmatically via the REST API

Toggle on ✨ AIto search by meaning, not just keywords. Ask natural questions like "that article about Netflix thumbnails" and LinkBrain will find it — even if the title is completely different.

Use Ask Your Brainto have a conversation with your saved knowledge. Ask "What have I saved about React performance?" and get answers with source links.

5. Organize with Collections & Tags

Create collections to group related links (unlimited on all plans). Collections auto-sort by topic using AI-generated tags — not just domains. LinkBrain also auto-suggests tags based on page content when you save.

Use the Knowledge Graph to see how your ideas connect visually. Open the Brain Insights tab in the Knowledge Graph for an AI-powered analysis of your entire link library. It generates personalized insight cards that reveal patterns about your interests — including your Knowledge DNA, Hidden Connections between topics, Deep Obsessions, Blind Spots, Rising Interests, and Your Unique Angle.

6. Review & Resurface

The Review tab uses spaced repetition to bring back links at the right time. Keep the ones that matter with 💎 Keep Forever, skip the rest. Build a reading streak to level up your brain.

7. Go Pro

Every feature is free up to 50 links. Upgrade to Pro ($5/mo) for unlimited links. That's the only difference — everything else is already unlocked. Manage your plan in Settings → Billing.
