Perplexity vs ChatGPT in 2026: Which Should You Use?

Perplexity is built around searching the web and giving answers with source links, while ChatGPT is a general assistant for writing, analysis, images, voice and coding that can also search the web. Both have a free plan. Perplexity Pro and ChatGPT Plus are both listed at $20 per month, so the better choice depends on whether you mostly look things up or mostly create and work with the assistant.

This guide compares the two using what each company says on its own website, checked on 20 October 2026.

Quick comparison

Perplexity: search and answers with sources

Perplexity's help centre describes it as an AI-powered search engine. You ask a question, it searches the web, and it gives a conversational answer "backed by verifiable sources", with citations and links to the original pages. Perplexity calls this an "answer engine" and contrasts it with traditional search engines that leave you to sort through a list of links. It also encourages you to double-check the sources.

Who it suits: people who use AI mainly to research, check facts, compare products or follow current topics, and who want links they can open to verify what they read.

Perplexity plans and prices

• Free: per Perplexity's help centre, "practically unlimited basic searches", 3 Pro Searches per day, 1 Research query per month and basic file uploads (limited). It has no access to advanced AI models, image generation or premium support.
• Pro: $20 a month, according to a Perplexity article dated 13 October 2026. The help centre lists extended Pro Search, image and video generation, and up to 50 file uploads per project. Pro Searches and file creation have weekly and monthly limits based on average use.
• Education Pro: $10 per month for verified students and educators, checked through SheerID.
• Max: $200 per month or $2000 per year (the annual option is for the web app only). Perplexity lists the highest level of access to advanced models, early access to new products and the highest limits for its browser agent.
• Enterprise Pro: per-seat pricing that starts at $40 per month or $400 per year per seat. Perplexity also lists Enterprise Max.
• API Platform: pay as you go, for developers.

Perplexity's pages also describe a credit system, where 100 credits equal $1. Max includes 10,000 credits per month. Pro has no set monthly amount of credits, though Perplexity says paid Consumer Pro plans also include a weekly amount of Computer usage. See Perplexity's plans page and your account settings for the current details, as Perplexity notes that prices are subject to change.

On Perplexity's Pro Search, the help centre explains the difference from a standard search: standard search gives "fast, basic answers" from one or two sources, while Pro Search gives "slower, in-depth answers" drawing on dozens of sources, with a choice of models.

ChatGPT: a general assistant that can search

ChatGPT is OpenAI's assistant. As well as chatting, OpenAI lists image creation, voice chats, file uploads, deep research, memory, projects, scheduled tasks, custom GPTs and Codex (its coding tool), depending on the plan.

ChatGPT can search the web too. OpenAI's help centre says it may search automatically when a question would benefit from current information, or you can start a search yourself from the tools menu. Search is available on the Free plan, on paid plans, and for people who are not signed in. Answers may include citations that you can select to open the source. OpenAI warns that search results and citations can be incomplete, outdated or incorrect, so it is worth opening the sources to confirm them.

Who it suits: people who want one assistant for many jobs, such as drafting, summarising, brainstorming, working with files and images, and coding help, with web search as one of several tools.

ChatGPT plans and prices

These come from OpenAI's official pricing page and help centre:

• Free: unlimited text chats, subject to abuse guardrails, with limited messages for uploads, image creation, voice chats and deep research.
• Go: more messages with tools, more uploads and image creation, and longer memory. It may include ads. It is listed at $8 USD per month in the US, as listed in OpenAI's pricing docs.
• Plus: $20 per month, billed monthly. It adds advanced reasoning models, expanded deep research, projects, scheduled tasks and custom GPTs. OpenAI notes that limits apply.
• Pro: from $100 per month, with $100, $200 and $500 tiers listed in OpenAI's help centre. It adds higher usage allowances and a Pro reasoning option.
• Business and Enterprise: team plans. Business starts at 2 users.

Perplexity vs ChatGPT: the key differences

• Starting point: Perplexity starts from a search and shows sources by design. ChatGPT starts from a conversation and adds search when it is useful.
• Free plans: Perplexity's free plan limits its deeper features: 3 Pro Searches a day and 1 Research query a month. ChatGPT's free plan allows unlimited text chats, with limits on uploads, images, voice and deep research.
• Paid price: The mainstream paid plans, Perplexity Pro and ChatGPT Plus, are both listed at $20. Perplexity's top individual plan is $200 per month. ChatGPT's Pro starts at $100 and goes up to $500.
• Models: Perplexity says its higher plans give access to advanced models from providers such as OpenAI and Anthropic. ChatGPT's help pages list OpenAI's own models.
• Extras: ChatGPT lists custom GPTs, projects and scheduled tasks on Plus. Perplexity lists image and video generation on Pro, and extended Create files and apps access and a browser assistant (Max Assistant on Comet) on Max.

Neither tool is perfect at sourcing. Both companies tell you to check the cited pages yourself.

Which should you pick?

• Mostly researching and checking facts: try Perplexity's free plan first and see whether the source links fit how you work.
• Mostly writing, studying, coding or making things: ChatGPT's Free or Plus plan covers more of those jobs in one place.
• Not sure: both free plans cost nothing, so use each for a week on your real tasks before you pay for either.

How we chose

We checked both tools against their official websites on 20 October 2026: Perplexity's help centre and blog, and OpenAI's ChatGPT pricing page and help centre. We did not use review sites. Where an official page did not state a fact, or where the pages disagreed, we left it out. We did not compare answer accuracy or speed, because we could not confirm that from official pages.
