Folio review
A connected research library with grounded AI, citation tools, discovery, and integrity checks.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Folio is a research workspace for students, academics, instructors, and institutions. It brings together scholarly and web search, source libraries, document writing, citation management, AI answers grounded in user-provided materials, and authorship verification. Researchers can import PDFs, URLs, DOIs, ISBNs, DOCX files, and reference libraries, then generate cited answers, bibliographies, and manuscript exports. Its browser extension adds a way to save and query sources while browsing.
The published plans give Folio a broad free starting point. Scholar costs $0 and includes unlimited documents and sources, citation styles with DOCX and BibTeX export, a monthly AI allowance, three authorship certificates per month, and an MCP connector. Fellow costs $9.99 per month and adds citation and claim integrity checking, Daily Document Audit, Discovery Agents, Research Radar, literature synthesis, and collaboration with view and comment. Chair costs $25 per month, adds 2× higher AI limits, unlimited proofreading, Deep Scan and Briefing Audio, Scholar AI in co-editing chat, and priority and direct founder support.
Folio’s strongest fit is for researchers who want one connected environment spanning discovery, writing, verification, and collaboration. Citation-graph discovery, literature synthesis, and tracking by topic, author, journal, and citation extend the library beyond basic storage. Integrations with Claude, ChatGPT, Cursor, VS Code, Zotero, ORCID, and MCP support research and coding workflows. Researchers seeking only lightweight reference storage may find the broader workspace unnecessary, while those who need grounded answers, structured discovery, and integrity checks should consider Folio.
