Top 5 Growing AI Tools - Trends & Analysis
No.1 - Muah.AI: Gained 97.3K monthly visit growth and 21.1% growth rate
Muah.AI experienced a slight increase in traffic, although a significant data breach exposing user data occurred in September 2025, potentially offsetting any positive impact from its customizable AI characters and uncensored language model; the slight increase may reflect the continued appeal of its multi-modal approach, including chat, voice, and photo exchange features despite the negative press.
No.2 - Claude Sonnet 4.5: Gained 8.5M monthly visit growth and 5.7% growth rate
Claude Sonnet 4.5 experienced slight growth due to the launch of Claude Sonnet 4.5, which is recognized as a leading coding model with enhanced autonomous capabilities. Additionally, the deployment of Claude to Deloitte's employees contributed to increased adoption.
No.3 - Character.ai: Gained 5.1M monthly visit growth and 2.9% growth rate
Character.AI experienced a slight increase in visits, potentially influenced by its new features, including the Community Feed and AI-powered AvatarFX. However, the growth may have been tempered by negative press, including lawsuits and the removal of Disney characters due to copyright issues.
No.4 - Gupshup: Gained 7.7K monthly visit growth and 1.6% growth rate
Gupshup experienced a slight increase in visits, potentially influenced by its recent $60 million funding round aimed at solidifying its market presence and expanding AI Agent adoption. The launch of pre-built AI Agents for marketing, sales, and support also likely contributed to increased user engagement.
No.5 - ChatGPT: Gained 57.3M monthly visit growth and 1.0% growth rate
ChatGPT experienced a slight increase in visits, potentially influenced by the introduction of the Instant Checkout feature and the availability of GPT-5. The launch of a dedicated ChatGPT experience with parental controls may also be a contributing factor.
