Perplexity

by Perplexity

AI answer engine that searches the web and cites sources in every answer. Pro lets you pick models such as GPT-6.1 Sol, Claude Sonnet 5.5 and Gemini 3.8 Flash; Max adds GPT-6 Astra, Gemini 4 Argon, Claude Opus 5.5 and Claude Fable 5.1.

Good

  • Citations in every answer, including on the Free plan
  • One subscription gives models from OpenAI, Anthropic, Google and others
  • Pro includes Deep Research and the Computer agent (credit-based)
  • Max adds Model Council, which asks several models the same question at once
  • Education Pro costs $10/mo with student verification

Watch out

  • Free plan cannot pick advanced models
  • Top models (Claude Opus 5.5, GPT-6 Astra, Gemini 4 Argon) are Max-only at $200/mo
  • Computer agent runs on credits that can run out
  • Less suited to long creative writing or large coding projects

ChatGPT

by OpenAI

OpenAI's AI assistant. Since October 7, 2026 it runs GPT-6 Sol on Plus, Pro, Business and Enterprise and GPT-6 Luna on Free and Go. GPT-6 Astra and GPT-6.1 Sol are available in Codex on Plus and higher.

Good

  • One app covers chat, image generation (ChatGPT Images 2.5 on every plan), voice and coding (Codex)
  • GPT-6 Sol on every plan from Plus ($20/mo) up
  • Go plan at $8/mo is a cheap step up from Free
  • Three Pro tiers ($100, $200, $500) let heavy users buy more usage without switching tools
  • Largest ecosystem of custom GPTs and third-party integrations

Watch out

  • Free and Go run the smaller GPT-6 Luna model
  • The Go plan may show ads
  • The strongest models (GPT-6 Astra, GPT-6.1 Sol) are in Codex and ChatGPT Work, not regular chat
  • Five consumer plans plus three Pro prices make the lineup hard to compare

Questions people ask

Is Perplexity more accurate than ChatGPT?

For questions about current facts, Perplexity is easier to check because every answer lists its sources. ChatGPT can also search the web, but Perplexity is built around citations.

Which is cheaper, Perplexity or ChatGPT?

Both main paid plans cost $20/mo (Perplexity Pro, ChatGPT Plus). ChatGPT Go is $8/mo. Top tiers: Perplexity Max $200/mo; ChatGPT Pro $100, $200 or $500/mo.

Does Perplexity use ChatGPT models?

Yes. Perplexity Pro lets you pick GPT-6.1 Sol, and Max adds GPT-6 Astra, alongside Claude, Gemini and other models.

Can Perplexity replace Google Search?

For research questions it can, because it reads several pages and summarises them with citations. For navigation, shopping and local results, a regular search engine is still faster.
