Web search and sources
This is the core difference. Perplexity describes itself as an answer engine: every question triggers a web search, and the answer comes with citations and links to the pages it used. ChatGPT is a general assistant that searches the web when needed and can produce longer deep research reports. Both show sources, but Perplexity makes them the center of every answer.
Limits differ on free plans. Perplexity Free offers practically unlimited basic searches, plus 3 Pro Searches per day and 1 Research query per month. ChatGPT Free offers unlimited text chats and limited deep research. If your work depends on checking claims — journalism, academic papers, market research — Perplexity’s format saves time. For answers that do not need sources, the difference fades.
Models: one vendor vs many
ChatGPT runs OpenAI’s own models; the plan decides which ones (GPT-5.6 Luna on Free, advanced reasoning models with GPT-6 on Plus, GPT-6 Astra on Pro). Perplexity Free picks the model for you, while Pro lets you choose among models from several vendors, including OpenAI’s GPT-5.4, Anthropic’s Claude Sonnet 4.6, Google’s Gemini 3.1 Pro and Nvidia’s Nemotron 3 Super. Perplexity Max adds GPT-5.5 and Claude Opus 4.7. If you like switching models, Perplexity Pro is a convenient single subscription.
Perplexity vs ChatGPT for coding
ChatGPT is the stronger coding tool on paper: Codex, OpenAI’s coding agent, is included on every plan (limited on Free and Go, expanded on Plus), and ChatGPT runs Python for data analysis. Perplexity’s Pro Search includes a code interpreter and Pro can create files and apps within limits, but Perplexity is not positioned as a coding assistant. For looking up documentation or an error message with sources, Perplexity is handy; for writing and running code, choose ChatGPT.
Perplexity vs ChatGPT pricing
- Free: both. Perplexity limits Pro Searches and Research; ChatGPT limits uploads (3 per day) and advanced features.
- Budget: ChatGPT Go at $8/mo (may include ads). Perplexity has no general low-cost tier, but Education Pro costs $10/mo for verified students and faculty.
- Main plan: Perplexity Pro and ChatGPT Plus both cost $20 a month. Perplexity Pro is $16.67/month when paid yearly ($200 a year); ChatGPT Plus is billed monthly only.
- Top tier: Perplexity Max at $200/mo; ChatGPT Pro from $100/mo up to $500/mo.

Data privacy
Both companies offer business plans that exclude your data from model training by default: Perplexity states that Enterprise Pro data is never used for training, and OpenAI says ChatGPT Business data is not used for training by default. On consumer plans, check each app’s data controls before sharing sensitive information. Perplexity also notes that images generated on Free, Pro and Max are for personal, non-commercial use only.
Which should you choose?
Choose Perplexity if most of what you do is finding, checking and summarizing information from the web. Choose ChatGPT if you want one assistant for writing, coding, images and files, with sources when you need them. For other options, see our ChatGPT alternatives list.
Frequently asked questions
Is Perplexity better than ChatGPT for research?
For research where sources matter, Perplexity is built for it: it searches the web for each question and its answers include citations and links. ChatGPT also searches the web and offers deep research reports, which are limited on the free plan. If you need to check where every claim comes from, start with Perplexity.
Is Perplexity free?
Yes. Perplexity's free plan includes practically unlimited basic searches, 3 Pro Searches per day and 1 Research query per month, but Perplexity picks the model for you. Perplexity Pro costs $20 a month, or $10 with Education Pro for verified students and faculty.
Does Perplexity use ChatGPT's models?
Perplexity Pro lets you choose among several third-party models, including OpenAI's GPT-5.4, Anthropic's Claude Sonnet 4.6 and Google's Gemini 3.1 Pro, according to its help center. Max adds GPT-5.5 and Claude Opus 4.7. So Pro subscribers can use an OpenAI model inside Perplexity's search-first interface, but not ChatGPT's own app features.
Can Perplexity replace ChatGPT?
For questions, research and summaries of web pages, often yes. For other tasks, ChatGPT offers more built-in tools: unlimited free text chats, Codex for coding, custom GPTs, scheduled tasks and voice chats on every plan. Many people use Perplexity for finding and checking information and ChatGPT for creating content and working on files.
