Small business research is mostly practical. What do competitors charge? Is this market growing? What does a new rule mean for you? Perplexity and ChatGPT can both answer these questions. Perplexity is built around finding answers with sources. ChatGPT treats research as one step in a longer job.
All prices and features below are as of October 2026, in US dollars, from each company's own pages. Both change often, so check before you pay.
The short verdict
- Pick Perplexity if most of your research is finding and checking facts on the web, and you want sources shown with every answer.
- Pick ChatGPT if research is the first step and you then write, plan or work with files in the same chat.
- If you already pay for one, try the free plan of the other on a week of real questions before you add a second bill.
How each one handles sources
Perplexity says every answer includes inline citations that show where each claim comes from (Perplexity pricing). Paid plans add premium data sources for finance and market work. The pricing page names PitchBook and Statista.
ChatGPT can search the web on every plan, including Free. OpenAI says answers that use web search may include citations, and a Sources button lists the pages it used (Searching the web with ChatGPT). OpenAI also says search results and citations can be incomplete, outdated or incorrect, and suggests opening the source to check it.
That advice applies to both tools. A citation tells you where to look. It does not prove the answer is right.
Plans and prices
Perplexity, from its pricing page:
- Free: $0. Citations in every answer, basic AI models and limited daily use.
- Pro: $17 a month when billed yearly. Deep research, a choice of top models and higher limits.
- Max: $167 a month when billed yearly, with the highest limits.
- Enterprise Pro: $34 per seat a month, billed yearly. Adds admin controls and single sign-on (enterprise pricing).
The page shows yearly prices. Check it for the monthly price in your country.
ChatGPT, from OpenAI's pages:
- Free: $0, with web search and limited deep research (pricing page).
- Plus: $20 a month, billed monthly (What is ChatGPT Plus?).
- Business: $25 per user a month billed monthly, or $20 billed yearly, from 2 users (billing help).
For one person, Perplexity Pro at its yearly price costs a little less a month than ChatGPT Plus billed monthly. For a team, ChatGPT Business is cheaper per seat than Perplexity Enterprise Pro at these list prices.
Which models you get
Perplexity says it picks a model for each question from several providers, including ChatGPT, Google Gemini and Anthropic Claude, and Pro users can choose a preferred model. ChatGPT uses OpenAI's own models. If you like to compare answers from different models, Perplexity makes that easier in one place.
What happens after the research
This is where the two differ most for a business.
- Perplexity is strongest at the question and answer step. Its paid plans can also create documents, but its core is search.
- ChatGPT is a general assistant. You can research a market, then ask it to turn the notes into a competitor analysis, a pricing table or an email, all in the same chat. The pricing page lists projects from the Plus plan up, to keep files and instructions together.
If you mostly need quick, sourced answers, the extra tools in ChatGPT may not matter. If research feeds your writing every day, they will.
Data and privacy
- Perplexity. On Free, Pro and Max, a setting called AI Data Retention is on by default, which lets Perplexity use your data for AI training. You can turn it off under Account settings, then Preferences. The opt-out applies to data from that date on. Perplexity says Enterprise data is never used for training (data collection at Perplexity).
- ChatGPT. On personal plans, you can turn off "Improve the model for everyone". OpenAI says it does not use Business workspace content for training by default (data controls).
Check these settings before you paste in client names, numbers or plans.
How to decide
- Write down five research questions you really needed answered last month.
- Ask both tools each question on their free plans.
- Open three sources from each answer and check that they say what the tool claims.
- Note which tool needed fewer follow-up questions to get a usable answer.
- Then ask each one to turn its answer into the thing you actually needed, such as an email or a one-page summary.
The tool that wins on steps 3 and 5 for your kind of work is the one to pay for.
If you are validating an idea, the steps in how to validate a business idea pair well with either tool. For other comparisons, see Copilot vs ChatGPT for business and ChatGPT vs Claude for business.
