How to choose
Match autonomy level first: local agents like agenticSeek avoid API fees but require hardware, while cloud toolkits like ToolUniverse scale faster. Check integrations with Zotero, WeChat, or existing codebases before committing. Watch pricing traps around hidden compute costs on long-running agents and verify human-in-the-loop controls for high-stakes research. Prioritize agents whose job description directly matches your data sources, whether documents, websites, or live experiments.
FAQ
Which agents work fully offline or locally?
agenticSeek and LobsterAI run without APIs; most others need some connectivity or external tools.
How do I handle academic literature versus web data?
Use llm-for-zotero or NanoResearch for papers and deepsite or PageIndex for web and documents.
What about keeping humans in control during long runs?
Deep-Research-skills and auto-deep-researcher-24x7 explicitly support oversight or scheduled pauses.
