According to @godofprompt, referencing data from Similarweb, ChatGPT is experiencing a decline in market share, indicating changing user preferences in the generative AI landscape (source: x.com/Similarweb/status/1988879389992386897). This shift highlights increased competition from emerging AI chatbots and platforms, such as Google's Gemini and Anthropic's Claude, which are rapidly expanding their user bases and enterprise integrations. The trend underscores new business opportunities for developers and organizations to differentiate offerings through enhanced features, domain-specific models, and improved user experiences. Companies seeking to leverage AI should monitor evolving platform capabilities and user engagement metrics to identify areas for innovation and market entry (source: x.com/Similarweb/status/1988879389992386897).

According to Sam Altman on Twitter, ChatGPT has updated its personalization page by consolidating personality configuration, custom instructions, and memory features into a single, streamlined interface. This change, rolling out over the next few days, is designed to improve usability and user experience for both individual and business users. The unified interface allows for more efficient workflow customization and deeper personalization, which creates new opportunities for enterprises to tailor AI interactions to their specific operational needs. This update also reflects a broader trend towards user-centric design in AI platforms, increasing adoption potential in enterprise and customer service environments (Source: Sam Altman, Twitter, Sep 16, 2025).
