P
AI tool
Perplexity
research the web with cited AI answers
Useful for finding public information, developing research leads and gathering citations to verify. Open sources to check dates, actors and conditions. Its value is reducing discovery work, not certifying every source or sentence.
Free plan and limits
A Standard free plan exists, with different advanced-model, research and file access from paid plans. Standard search availability does not imply unlimited access to every research feature; check the signed-in plan table.
Important limitations
A citation may not support the whole claim. Summaries can confuse old events with new developments; paywalls and syndicated sources require additional verification.
When to choose an alternative
NotebookLM is a candidate when you already own the source set; ChatGPT or Claude may fit drafting and revision better. Search and writing do not have to use the same tool.
Alternative suggestions are editorial, task-based judgments, not standardized performance tests.
