TL;DR: Perplexity is an AI answer engine built around web search, with citations on every answer, which makes it better for research and fact-finding. ChatGPT is a general AI assistant that’s stronger for writing, coding, images, voice and getting tasks done. Both have free plans. Paid plans cost the same at the entry level: Perplexity Pro and ChatGPT Plus are $20 a month. ChatGPT also has an $8 Go plan; Perplexity Pro drops to $17 a month billed annually. The top tiers are Perplexity Max at $200 and ChatGPT Pro from $100.
Last updated: October 23, 2026. Based on Perplexity and OpenAI official pricing and help pages.
Perplexity and ChatGPT overlap more every year: ChatGPT searches the web, and Perplexity can create documents and apps. But they’re still built for different jobs. This comparison is based on each company’s published plans and features, not our own benchmarks.
What’s the difference between Perplexity and ChatGPT?
Perplexity is search-first with citations; ChatGPT is assistant-first with search as one tool. Perplexity’s help center describes Pro as designed “to enhance your search experience,” and Pro answers include “10x as many citations per answer.” ChatGPT’s pricing page leads with chat, image creation, voice, deep research, Codex and agents.

What do the free plans include?
Perplexity’s free plan gives “practically unlimited basic searches”; ChatGPT’s free plan gives unlimited text chats with limits on tools. Per Perplexity’s plan guide, Standard includes search history, “very limited” Pro Searches and basic file uploads, but no advanced model choice or image generation. ChatGPT Free includes “unlimited text chats” (subject to abuse guardrails) plus limited uploads, image creation, voice, deep research and Codex access.
If you mainly want quick, sourced answers, Perplexity Free is enough for many people. If you want help writing or brainstorming, ChatGPT Free covers more ground.
Which is better for research?
Perplexity, for most research tasks, because citations are built in. Every answer links its sources, so you can check claims quickly. Pro adds “Pro Search” for multi-step questions and a Research mode that “automatically selects the optimal combination of models for in-depth research” and generates reports.
ChatGPT’s deep research also produces cited reports and is strong for long, structured investigations. The practical difference: Perplexity is faster for everyday “look it up” questions; ChatGPT deep research suits occasional big reports.
Whichever you use, AI answers can be wrong. Open the sources for anything important.
Which is better for writing, coding and everyday tasks?
ChatGPT. Its plans include custom GPTs, projects, scheduled tasks, image creation, voice chats, Codex for coding, and ChatGPT Work for agent-style tasks. Perplexity can draft documents and apps through its “Create files and apps” feature, but ChatGPT’s toolset for creating and editing is broader.
| Task | Better pick |
|---|---|
| Quick factual answers with sources | Perplexity |
| Comparing products or news coverage | Perplexity |
| Writing and editing | ChatGPT |
| Coding | ChatGPT (Codex) |
| Image creation | ChatGPT |
| Voice conversations | ChatGPT |
| Trying models from several companies | Perplexity Pro |
Can you use ChatGPT models inside Perplexity?
Yes. Perplexity Pro lets you pick from several companies’ models, including OpenAI’s GPT models, Anthropic’s Claude and Google’s Gemini, plus its in-house Sonar. Perplexity notes access to advanced models “may be limited during weeks of especially heavy usage.” You get the models inside Perplexity’s search experience, not ChatGPT’s full feature set.
Which should you pay for?
Pay for Perplexity Pro if research is your main use; pay for ChatGPT Plus if you want one assistant for everything. If you’re on a budget, ChatGPT Go at $8 is the cheapest paid option. Many people use Perplexity Free for searching alongside a paid ChatGPT plan.
