Perplexity vs. ChatGPT: Which Is the Better Research Tool for a Small Business?
Perplexity Pro is built around cited answers; ChatGPT Plus is the broader assistant. For research, the tests split in an interesting way.
Perplexity vs ChatGPT is the choice to make if your AI use is mostly looking things up: competitors, suppliers, regulations, market questions. Perplexity is an answer engine that cites its sources by default. ChatGPT is a general assistant that also searches the web and runs deep research reports. On price they sit close together, around $17 to $20 a month for the paid tiers.
In Tom's Guide's March 2026 research test, Perplexity won all three rounds, mostly on the depth and number of sources. G2's April 2026 head-to-head was more mixed: ChatGPT won 5 of 12 tests, Perplexity 3, with 4 split. Prices below come from each company's official pages, checked November 10, 2026.

Pick Perplexity if most of your AI time is research and you need to see where every answer came from, for example checking competitors, regulations or supplier claims. Pick ChatGPT if research is one step in a bigger job, since it can take the findings and turn them into a proposal, a spreadsheet or a social post in the same place. Many owners run both: Perplexity's free plan for quick sourced lookups, and a paid ChatGPT plan for everything else.
