The system also supports a spaced repetition / active recall workflow so that you can review key ideas over time, helping retention. Recall organizes what you learn automatically using tags and keywords, builds a graph of your saved content (knowledge graph), and provides augmented browsing so related past content resurfaces when you are browsing new material.
- Students & Lifelong Learners: who need to read lots of content and retain what matters without overload.
- Professionals & Researchers: managing large amounts of information across reports, articles, papers, videos.
- Content Consumers: people who use blogs, videos, podcasts heavily and want summaries + organization.
- Knowledge Workers & Productivity Junkies: interested in building a connected personal knowledge base.
- Anyone Who Forgets Things: people who want to remember insights over long periods using spaced repetition and active recall.
How to Use It:
- Add Content: Use browser extension, mobile app (beta), or in-app “create card” to save content (articles, PDFs, videos etc.).
- Summarize or Chat: Generate concise or detailed summaries; chat with the saved content to ask questions or explore it.
- Take Notes & Customize: Use the Notebook tab to edit summaries, make your own notes, link content cards together.
- Organize: Tags, automatic categorization, and knowledge graph help you see relationships and navigate your learning.
- Review & Retain: Use quiz features, spaced repetition, and active recall to reinforce what you’ve consumed.
- Knowledge Graph + Connections: Automatically links saved content via keywords; allows you to explore related cards visually.
- Augmented Browsing: Highlights related content from your knowledge base while you browse new material, helping you recall past insights.
- Spaced Repetition & Quiz-Style Reviews: Turn saved content into quizzes to test your retention over time.
- Support for Many Content Types: Works with videos, articles, PDFs, Google Docs etc., so you’re not limited to just text.
- Cross-Platform & Local-First Privacy: Works on browser, mobile; much processing is local ensuring privacy; sync across devices.
- Great tool for turning passive content consumption into active learning.
- Helps keep knowledge organized and retrievable instead of lost in tabs or notebooks.
- Reminder / review features increase retention and memory.
- Graph view + linking help surface unexpected connections.
- Multi-language support and variety of content types are strong pluses.
- Some “unlimited” claims may have caps or fair-use limits in practice.
- Features in beta (like augmented browsing, mobile apps) may have rough edges or incomplete polish.
- For very high volumes of video or long content, summarization may still take time or need heavy resources.
- Interface/UX may be overwhelming initially when knowledge base becomes very large.
- Quality and depth of summaries / chat depend on the AI model; sometimes detail or nuance may be lost.
