AI research tools help find papers, summarize sources, map topics, and manage notes. Best pick depends on work type, source quality, privacy needs, and budget.

What to check first

• Source coverage: papers, patents, web, books, internal docs
• Citation support: links, DOI, quote trace, export formats
• Search quality: semantic search, keyword search, filters
• Summary quality: clear limits, source-grounded output
• Note workflow: folders, tags, highlights, shared spaces
• Export: BibTeX, RIS, CSV, Markdown, PDF notes
• Privacy: data use policy, team controls, retention settings
• Cost: monthly price, seat price, usage caps, overage rules
