Genuinely autonomous, multi-source research synthesis with real citations
Can research across both the public web and a company’s own private documents
Interruptible mid-run for follow-up refinement rather than requiring a full restart

Not a standalone product — access and usage limits depend entirely on your existing ChatGPT plan tier
Reports still benefit from verifying key citations before relying on them for important decisions
Full document integration features require connecting external cloud storage accounts

Largest user base and ecosystem of any AI assistant, with the most third-party integrations
Genuinely broad capability across writing, coding, research, and file analysis
Custom GPTs allow tailoring the assistant to specific repeated tasks
Frequent model updates keep it competitive on raw capability

Free tier has usage limits and access to a lower-tier model than paid plans
Can produce confident-sounding but incorrect information, especially without browsing enabled
Breadth can mean less depth than a tool purpose-built for one specific workflow
Data usage and training policies require attention for sensitive or regulated work
