Direct answer
Consider Consensus when your question requires research papers; consider Perplexity for broader web-source discovery. A citation from either service still needs to be checked in context.
Academic evidence or current web information
Consensus's documented paper-search and study-summary features fit an evidence-oriented question. Perplexity's search workflow is broader and can help locate official help pages, announcements, and other web material. For product rules or recent pricing, the provider's own current documentation is usually the better destination to verify.
Avoid the citation shortcut
A paper can be relevant without supporting the exact conclusion an assistant gives. Check study design, population, limitations, and whether the cited passage actually supports the claim. For a web page, check the publisher, date, and primary source behind the statement.
Free-tier caveats
Consensus's advanced message allowance has an official-source conflict, while Perplexity's help describes limited advanced search and uploads without a universal numerical count. The table identifies what was actually established. Neither absence of a fixed count nor the presence of a link proves unlimited research capability.
A practical decision check
Write down your required task, your acceptable limits, and the result you need to keep or export. Check those requirements against the sourced table above and the current account screen before paying. A free allowance is a way to evaluate suitability; it does not establish output quality or guarantee ongoing access.
Methodology
This is an editorial comparison of official product documentation checked 2026-10-22. Recommendations concern workflow fit, not measured accuracy, earnings, or speed. We did not run a hands-on benchmark. Unknown details and conflicting sources remain labeled in the fact table.
