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.
