Head to head scenarios
Breaking news and social reaction
Winner: Grok. Real time search of X posts is the one thing Perplexity does not do. For a fast moving story, Grok surfaces what people are posting within minutes.
A sourced briefing for your boss
Winner: Perplexity. Every claim comes with a numbered source, and Deep Research builds a longer cited report. That is easier to defend than a summary of social posts.
Company and investment research
Winner: Perplexity. PitchBook, Statista and S&P Capital IQ data on Pro give it facts Grok does not list.
Images and short videos
Winner: Grok. Image and video creation are included on Premium at $30. Perplexity reserves video for Max at $167.
Developers who want an API with their plan
Winner: Grok. Paid Grok plans include Grok API access, and xAI publishes API rates for Grok 4.7 of $2 to $4 per million input tokens and $6 to $12 per million output tokens. Perplexity's consumer plans do not list API access, so developers pay for it separately.
Using several AI models without several subscriptions
Winner: Perplexity. One plan covers models from several labs. Grok only runs Grok models.
Privacy
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. Enterprise Pro lists no training on data, SSO, SOC 2 Type II and HIPAA.
Grok Teams lists SSO plus admin and spend controls. xAI's privacy policy page was not reachable when we compared plans in October 2026, so read it directly before putting work data into Grok. Consumer Grok plans are tied to X accounts.
Verdict
Perplexity is the better research tool and the cheaper subscription, with citations, premium data and model choice. Grok is the better feed for what is happening on X right now, and the cheaper route to video. If you need answers you can defend, choose Perplexity; if you need to know what X is saying, choose Grok.
