ChatGPT vs Grok (2026): Traffic, Growth and Key Differences
This page compares ChatGPT and Grok by how much their websites are used: monthly visits to chatgpt.com and grok.com since Jan 2025 (SimilarWeb estimates, as shown on each tool's TrendBreakouts profile). In July 2026, ChatGPT had 26 times as many visits as Grok: 5.45B against 210M. We rank by use, not quality, and have not tested either tool.
How ChatGPT and Grok differ
Both handle chat, image creation and coding. Grok's distinguishing feature is real-time information from the web and X, and it is built into X itself; paid SuperGrok plans raise its usage limits. ChatGPT instead connects to work files and apps such as Gmail and Slack, and offers business plans alongside personal ones.

What these numbers can and cannot tell you
- Estimates. Visits are SimilarWeb estimates of total monthly visits to each website, as shown on the TrendBreakouts profiles. They are comparable across sites but not exact, and different months can come from different SimilarWeb data releases, so treat small month-to-month moves as noise.
- Websites only. Not counted for ChatGPT: Use in the ChatGPT mobile and desktop apps and through the OpenAI API (openai.com is a separate site). Not counted for Grok: Use of Grok inside X (x.com) and in the Grok mobile apps.
- Visits, not people or usage. One person can make many visits, and a long working session counts the same as a quick question.
- Not a quality ranking. More visits means more use of the website, not a better tool for your task.
