Perplexity

Perplexity is an AI search and research assistant. Instead of returning only a list of pages, it builds an answer around a question and includes links to supporting sources. Follow-up questions let you narrow the topic without starting a new search from scratch.

What you can do

• Web-backed answers with references you can open and inspect.
• Follow-up questions for narrowing a comparison or exploring an unfamiliar term.
• More extensive search and research options on eligible paid plans.

A useful starting workflow

For a software comparison, specify the use case, platform and budget first. Ask which official pages document each required feature. Open those pages and check that the answer reflects the current plan, rather than an old announcement. Keep a separate note of the evidence behind each purchase decision.

What to check

A citation helps you investigate a claim, but it does not automatically validate it. Check whether the linked page actually supports the sentence and whether its date matters. For medical, legal or financial decisions, use appropriate professional sources rather than relying on the answer alone.

Pricing and access

A free plan supports basic use. Paid subscriptions add capabilities and usage; the plan comparison explains the current differences.
