Refly
AI research workspace that clips web pages, PDFs, and YouTube videos then lets you ask questions across all saved content with source-cited answers.
Refly is an AI-powered reading and research workspace designed to reduce context-switching during research workflows. Users save articles, PDFs, and YouTube videos using a browser extension, then ask natural language questions across all saved content in threaded conversations that cite the specific source documents for every response. Unlike single-document Q&A tools, Refly allows cross-document synthesis - drawing simultaneously on multiple saved sources to answer complex questions. The workspace includes a canvas view for organizing research spatially, AI-generated summaries for rapid document review, and Markdown export for transferring research into note-taking tools. Refly is free for individual use with storage limits; Pro plans remove caps and add advanced features.
Key Features
- Browser extension clips any web page, PDF, or YouTube video into the workspace in one click without copy-paste
- Thread-based Q&A grounds answers in saved content and cites the specific source documents for every response generated
- Cross-document synthesis draws on multiple saved articles and PDFs simultaneously to answer complex multi-source questions
- AI summarization extracts key points from any saved document or video for rapid review without reading the full text
- Canvas view organizes research nodes spatially for building visual knowledge maps from saved sources
- Full-text and semantic search across all saved content using exact keywords or natural language intent queries
- Markdown export transfers research notes and Q&A threads to tools like Obsidian, Notion, or any markdown editor
Use Cases
- Researchers tracking a topic across dozens of papers and articles without manually cross-referencing individual sources
- Content writers building research bases before drafting long-form articles and needing quick synthesis across saved sources
- Students collecting and questioning academic resources for essays and literature reviews in one organized workspace
- Analysts monitoring competitive intelligence by saving and questioning news, filings, and reports in a central searchable hub
Pros
- Cross-document Q&A across multiple saved sources sets Refly apart from tools that only answer per individual document
- Source citations on every answer reduce hallucination risk and make it easy to verify claims before using them in writing
- Free plan lets individual researchers evaluate the full Q&A workflow before committing to a paid subscription
Cons
- Smaller feature set and less mature UX compared to established alternatives like NotebookLM and Mem AI
- Knowledge base search quality degrades with very large document collections against the free tier storage limits
- Smaller community than Notion AI or Obsidian with fewer shared templates and workflow guides for research setups
