Perplexity

Search and verify academic works

Stop guessing if a citation is correct. Use `search_works` to find exact papers by title or author, then pull the full metadata using `get_work`. You'll get abstracts, publication dates, and DOI links pushed straight into your chat window.

Filter research by publisher and journal

Narrow down your literature review by checking specific journals or publishers. The `get_journal` and `get_publisher` tools provide ISSNs and work counts for your target sources. Filter your results further by publication type using `get_types` to ensure you only see peer-reviewed articles or books.

Examine funding and member data

Trace the money behind the research by looking up funders with `get_funder`. You can see which organizations support specific projects and their associated work counts. Use `search_members` to view CrossRef member details and understand the publishing prefixes associated with different institutions.
