WHY IT MATTERS
Stop Outsourcing Your Thinking
Most people now ask chatbots before they ask themselves. A second brain changes the order: your own notes, articles, videos, PDFs, and ideas become the first source of context, not an archive you forget.
Frictionless Capture
Save articles, YouTube videos, podcasts, PDFs, and notes from the web or your phone in one click, so useful knowledge stops disappearing into tabs and bookmarks.
Self-Organizing Library
AI summaries and automatic tags sort everything you save, so your knowledge stays organized without folders to maintain by hand.
Chat With Your Knowledge
Chat across your full library, selected sources, or the web. Recall cites your own saved sources first, so old articles, videos, notes, and PDFs become context for new questions.
Connected Knowledge Graph
Recall links related ideas in a knowledge graph and resurfaces related content while you browse, so you see how your knowledge connects and rediscover it in context.
Enhanced Long-Term Memory
Built-in quizzes and spaced repetition resurface the most important ideas on schedule, turning what you save into lasting memory.
Private and Portable
Recall never trains AI on your content. Export everything anytime, and use the API or MCP to connect your knowledge to the AI tools and workflows you already use.

SIDE BY SIDE
Recall vs. Traditional Second Brain Apps
A quick look at what changes when your knowledge system is built around AI capture, retrieval, and memory instead of manual filing.
| Feature | Recall | Traditional Notes Apps |
|---|---|---|
| Capture | ||
Best for | A lifelong AI knowledge base for web content, videos, podcasts, PDFs, and notes | Self-authored notes, manual workspaces, or project-specific research |
Supported sources | Articles, YouTube videos, podcasts, PDFs, webpages, highlights, and rich notes. See all supported content | Usually strongest for typed notes, documents, or manually imported sources |
| Organization | ||
Setup required | Automatic summaries, tags, categories, and knowledge graph connections | Folders, templates, tags, backlinks, or databases you maintain yourself |
| Connections | ||
Linking related content | Automatically connects related content, resurfaces it while you browse, and maps it in a knowledge graph you can also edit by hand | Manual backlinks and tags you create and maintain yourself |
| Retrieval | ||
Finding old knowledge | Semantic search and library-wide chat that cites your saved sources first | Search, backlinks, folders, or manual graph navigation |
| Memory | ||
Long-term retention | Built-in quizzes and spaced repetition | Usually requires flashcard plugins, manual review, or a separate study tool |
| Workflow | ||
AI assistant access | MCP and API access connect your saved knowledge to external AI workflows MCP docs | Often limited to exports, plugins, or one-app AI features |
Free plan | Unlimited saves with limited AI summaries | Varies by app; many limit sync, storage, AI, or collaboration |
Quick comparison: choose a manual notes app if you want to design every folder, tag, and template yourself. Choose Recall if you want an AI knowledge base that captures, summarizes, organizes, resurfaces, and remembers knowledge automatically.

I've been building several second brains for years. Recall is one of those tools that feels like a drastic improvement on what you're already using.
