Pay for Perplexity if most of your questions need sources, Claude if you write code or work in Projects, and ChatGPT if you want one tool for a bit of everything. If you only chat a few times a week, the free plans are enough, and you don't need to pay for any of them.
Quick verdict
- Pick ChatGPT if you want one app for writing, images, voice chats and scheduled tasks.
- Pick Perplexity if you look things up and want every answer to show where it came from.
- Pick Claude if you write code or work in Projects and want Claude Code in the same plan.
- Pick two if research is half your day. Perplexity Pro and Claude Pro cost $34 a month together on annual billing.

How we compared ChatGPT, Perplexity and Claude
We compared the three on the plan pages each company publishes, checked on October 20, 2026. We read what each plan includes, what it costs and how it bills. We also read the three top-ranking comparisons for "perplexity vs chatgpt vs claude" to see what they leave out. We did not run the same prompts in all three tools for this article, so the verdicts below come from what each plan offers, not from output tests.
Perplexity wins for research with sources
Perplexity is the pick when you need to check where an answer came from. Perplexity says every answer "includes inline citations from trusted sources, so you can verify claims." That's the whole product, not a mode you switch on.
Perplexity Pro also lets you choose the model behind the answer. Its Pro page lists GPT-6.1 Sol, Claude Sonnet 5.5, Gemini 3.8 Flash, Grok 4.7, Kimi K3 and GLM 5.3. So a Pro plan gets you a version of OpenAI's and Anthropic's models inside a search-first app. Pro also adds deep research, expanded access to Computer, Perplexity's task-running agent, and 4,000 bonus credits.
ChatGPT Plus has "expanded deep research" too, and Claude Free includes web search. If you want a longer, report-style comparison, see our deep research compared guide.
Claude wins for coding and project work
Claude is the pick if you write code, because Claude Pro includes Claude Code. It isn't on the free plan. Pro also adds unlimited Projects, Claude in Chrome (Claude inside your browser) and all three Claude models, Opus, Sonnet and Haiku.
Usage works differently from the others. Claude's limits reset on a rolling five-hour window, and Pro gives "at least 5x more usage per 5-hour session than Free," plus weekly limits. On Pro, Anthropic's newest model, Fable, costs extra: it is "available through usage credits."
ChatGPT Plus lists "expanded Codex usage," so it's a fair second choice for code. For a side-by-side of the two chat apps, see ChatGPT vs Claude vs Gemini.
ChatGPT wins as the everyday all-rounder
ChatGPT is the pick if you want one app that does a bit of everything. OpenAI's plans cover image creation, voice chats, longer memory, Projects, scheduled tasks and custom GPTs. Its free plan offers "unlimited text chats with GPT-6," subject to abuse guardrails. No other free plan here states that.
Two catches. The Go plan "may include ads." And the context window, how much of a chat the model keeps in view, is smaller on cheaper plans. OpenAI lists 27K tokens on Free, 54K on Go and Plus, and 128K on Pro for GPT Instant.
Pricing: what do the plans cost in October 2026?
The entry paid plans cost $17 to $20 a month, depending on billing. Here is what each plan costs, by plan and billing type.
| Tool | Plan | Price | Billing note |
|---|---|---|---|
| ChatGPT | Free | $0 | Unlimited text chats with GPT-6 |
| ChatGPT | Go | $8/month (third-party) | Monthly only, may include ads |
| ChatGPT | Plus | $20/month (third-party) | Monthly only |
| ChatGPT | Pro | From $100/month | Three usage tiers |
| Perplexity | Pro | $17/month billed annually | Third parties list $20 monthly |
| Perplexity | Max | $167/month billed annually | Third parties list $200 monthly |
| Claude | Free | $0 | Sonnet and Haiku, up to 5 Projects |
| Claude | Pro | $17/month billed annually, $20 monthly | $200 billed up front for the year |
| Claude | Max | From $100/month | 5x or 20x Pro usage |
OpenAI's pricing page didn't show Go or Plus dollar amounts when we checked; the page renders them per region. The $8 and $20 figures come from third-party price trackers, so confirm them on ChatGPT's pricing page. Perplexity's own page shows only annual prices, so the $20 monthly figure is also third-party.
All three on monthly billing come to about $60 a month, using third-party prices for ChatGPT Plus and Perplexity Pro monthly. Perplexity Pro plus Claude Pro on annual billing is $34 a month, or $408 a year. Check current prices on Claude's pricing page and Perplexity Pro.
Which should you pick? Match the plan to your main job
Pick by the job you do most often, then add a second plan only if a second job fills hours of your week.
In short, ChatGPT is the all-rounder, Perplexity is for research with sources, and Claude is for coding or Projects.
- Mostly research and fact-checking: Perplexity Pro.
- Mostly code or Projects: Claude Pro.
- A mix of writing, images and voice: ChatGPT Plus.
- Heavy research and heavy writing: Perplexity Pro plus Claude Pro, $34 a month on annual billing.
One rule: if you hit the free plan's limit less than once a week, stay free.
Pick none of them if the free plans already cover you
Pick none of them if you chat a few times a week and rarely hit a limit. ChatGPT Free offers unlimited text chats with GPT-6, and Claude Free includes web search, file creation and code execution. That covers casual use.
Skip Perplexity Pro if you mostly write rather than research. Skip Claude Pro if you never touch code or Projects. Skip ChatGPT Plus if you only want sourced answers. A team buying seats should look at business plans instead: Perplexity Enterprise Pro is $34 a month per seat billed annually, and Claude Team Standard is $20 a seat billed annually or $25 monthly.
