PROS
✓Perplexity searches the web first and generates its answer from those results second, rather than answering from memory and citing sources afterward — this ordering makes it structurally harder for the model to state something no source actually supports.
✓Citations are included automatically on every answer rather than only when a browsing toggle is on, so you can check the source without an extra step.
✓Free tier includes 5 Deep Research queries and 3 Pro Searches per day with no subscription required — more generous free research access than ChatGPT's 5 lightweight-only queries.
✓Comet, Perplexity's Chromium-based AI browser, became a free download for all users on October 1, 2025, letting the AI act directly inside your browsing session.
✓Pro plan is $20/month or $200/year (about $16.67/month, a 17% saving), matching ChatGPT Plus and Claude Pro pricing directly.
✓Perplexity Deep Research scored 93.9% on the SimpleQA benchmark by the company's own reporting, ahead of several general-purpose model deep-research modes.
CONS
✕Max tier costs $200/month — the same price as ChatGPT Pro — but its main extras (Sora 2 Pro video, Nano Banana Pro images) are secondary to Perplexity's core search use case.
✕Free tier file uploads are capped at 5MB per file with only 8,000-token output, far below Pro's 50MB/32,000-token allowance.
✕One faculty comparison noted Perplexity can 'incorrectly interpret information it gleans from the internet,' producing responses that are incorrect or incomplete despite citations being present.
✕For pure coding work, one hands-on demo found Perplexity's web-search citations can 'fill up the context window' and become a distraction rather than a help.
✕The original 'give a month, get a month' referral program and the Comet cash-referral program both concluded in October and November 2025 respectively, so current earning mechanics may differ from older reviews.
✕Deep Research and Pro Search caps on the free tier (5 and 3 per day) reset daily rather than accumulating, so unused queries don't roll over.
