Head to head scenarios
Quick factual lookups
Winner: Perplexity. A short answer with numbered sources is its core format, and the free plan handles simple questions well.
Long research reports
Winner: Gemini for most people. Deep Research is free on Gemini, and AI Pro raises limits for $19.99. Perplexity's version is paid but worth it for business research because of its premium data sources.
Company, market and investor research
Winner: Perplexity. PitchBook, Statista and S&P Capital IQ data on Pro give it facts that general web research does not reach.
Everyday work in Gmail and Docs
Winner: Gemini. It works inside Gmail and Docs from AI Plus at $4.99. Perplexity connects to apps but does not live inside them.
Images, video and creative tasks
Winner: Gemini. Image generation is on the free plan and video starts at $4.99. Perplexity saves video for the $167 Max tier.
Comparing models side by side
Winner: Perplexity. One subscription covers models from several labs, including Gemini itself.
Privacy
Google's Gemini privacy hub states that with Keep Activity on, chats are saved and used to train models, auto deleting after 18 months by default, and a subset is reviewed by human reviewers after being disconnected from your account. Turning Keep Activity off stops training use of future chats, which are then kept for 72 hours.
Perplexity's privacy notice says it uses prompts, queries and uploads to provide the service and understand preferences, and states it does not use email content to train models. Incognito mode limits saved history. Enterprise Pro lists no training on data, SOC 2 Type II and HIPAA.
Verdict
Perplexity is the better research engine when sources and premium data matter. Gemini is the better assistant overall, with free Deep Research, Google app integration, video and storage for about the same money. If you research for a living, pay for Perplexity; if research is one task among many, Gemini covers it and more.
