Same price, different jobs. Perplexity ($20/mo Pro) is an AI answer engine — search-first, with a citation on every answer and a per-query model picker (GPT, Claude, Gemini, Grok). ChatGPT ($20/mo Plus, or $8/mo Go) is the broadest general assistant — Sora video, Codex, agents, image gen and voice on top of chat. Pick Perplexity for research you need to verify; pick ChatGPT for making things and all-round use. Both have solid free tiers to try first.

The honest verdict
This isn't a like-for-like fight — it's a question of which job you're hiring the tool for. Reach for Perplexity when the answer matters more than the artifact: sourced research, quick factual lookups, and the freedom to pick the underlying model per query. Reach for ChatGPT when you need to make something — draft, code, generate images or video, run agents — from one broad tool. They cost the same at $20, so plenty of people keep the free tier of one and pay for the other. If you must choose a single paid plan: research-heavy → Perplexity, everything-else → ChatGPT.
FAQ
Is Perplexity better than ChatGPT?
They're built for different jobs, so neither is universally better. Perplexity is an AI answer engine: search-first, with inline citations on every answer — the pick for research you need to verify. ChatGPT is a general-purpose assistant with a far broader toolset (Sora video, Codex, image generation, agents, advanced voice) — the pick for creating things and all-round use. For sourced questions, Perplexity; for everything else, ChatGPT.
Is Perplexity or ChatGPT cheaper?
They're the same at the mainstream tier: Perplexity Pro and ChatGPT Plus both cost $20/mo, and both have a free tier. The tie-breaker is ChatGPT's $8/mo Go plan — the cheapest paid option between the two. Prices verified June 2026; usage limits change often.
Does Perplexity use ChatGPT or GPT models?
Partly — Perplexity runs several frontier models, and on Pro you choose per query among GPT-5.x, Claude (Opus/Sonnet), Gemini 3.1 Pro, Grok, and its own Sonar model. So it can use OpenAI's models, but it isn't limited to them the way ChatGPT is. That model-picker is one of Perplexity Pro's main draws.
Can Perplexity replace ChatGPT?
For search and research with sources, Perplexity often can — and many people prefer it there. But ChatGPT does much more: content creation, coding (Codex), image and video generation (Sora), advanced voice, and agent tasks. A common setup is Perplexity for questions you need cited and ChatGPT for making things. If you can only pay for one and you mostly create, ChatGPT is safer; if you mostly research, Perplexity.
Which is better for research?
Perplexity is purpose-built for it — search-first, inline citations, and Deep Research on Pro make sources easy to check. ChatGPT also has Deep Research (on Plus and up) and can browse the web, but its answers aren't citation-first by design. If verifiable sourcing is the priority, Perplexity has the edge; if you also need to draft, code, or generate media from the same tool, ChatGPT wins on breadth.
