The latest traffic numbers for April 2026 show how the big AI chat tools are performing month to month. ChatGPT continues to sit far ahead of everyone else, but some smaller players are growing faster in the short term.

According to Similarweb data, here is how the monthly traffic looked:

  • ChatGPT: 182.8 million visits
  • Gemini: 91.6 million visits
  • Claude: 26.8 million visits
  • DeepSeek: 13.3 million visits
  • Grok: 9.5 million visits
  • Perplexity: 5.2 million visits

ChatGPT remains the clear leader by a big margin. Gemini is in second place but still roughly half of ChatGPT’s traffic.

What Changed in the Last Four Weeks

When we look at the short-term trends over the past four weeks, the picture gets more interesting:

  • DeepSeek grew 32% the biggest jump in the group.
  • Claude rose 26%.
  • Gemini went up 9%.
  • ChatGPT grew a steady 5%.
  • Perplexity was almost flat at 2%.
  • Grok dropped -21%.

DeepSeek and Claude are moving fast right now. ChatGPT is still adding users but at a more measured pace. Grok is the only one showing a clear decline in this period.

What This Data Tells Us

ChatGPT has built a very strong position. Millions of people use it regularly, and it keeps growing even if the pace is slower than some newer tools. Its size gives it a lot of staying power.

DeepSeek’s sharp rise suggests it is finding a good spot in the market, possibly with users who like its style or specific strengths. Claude is also attracting more people quickly, which could come from improvements in how it handles tasks or from word-of-mouth among power users.

Grok’s drop in the last four weeks stands out. Short-term dips can happen for many reasons; maybe seasonal changes, competition from new features elsewhere, or just normal ups and downs in traffic. One month does not tell the full story, but it is something to watch.

Perplexity stays smaller but steady. Gemini sits in a solid middle spot and keeps growing at a healthy rate.

Why These Numbers Matter for Founders and Builders

Traffic is one of the clearest signals of real user interest. High and growing traffic usually means people find the product useful enough to come back.

For anyone working on AI products, this chart shows a few practical things:

  • Scale helps a lot. ChatGPT’s lead is hard to catch, but it also shows there is room for specialists to grow fast in certain areas.
  • Short-term surges like DeepSeek and Claude can turn into longer-term gains if the product keeps delivering value.
  • Even big players see fluctuations. A single month’s drop does not mean the end, but it is a reminder to keep improving the experience.

The Gen AI space is still young and changing quickly. New features, better models, and fresh ideas can shift these numbers fast. Right now ChatGPT dominates, but the fast growth from DeepSeek and Claude shows that users are willing to try and stick with alternatives that solve their needs well.
