Service Degradation, Feature Loss, and the Rise of Superior AI CompetitorsInitially, the free version of your platform impressed me with a range of strong features that encouraged me to dive deeper and subscribe to the Plus plan.However, after subscribing, I was surprised to find that many of the essential features I valued — such as the ability to send and receive Word, Excel, and other file formats — had been removed.Additionally, the performance of simple conversations became noticeably slower, and the platform’s functionality started to feel limited compared to others.Frankly, platforms such as Claude (Anthropic), Perplexity AI, Microsoft Copilot, DeepSeek AI, ChatBCat, and Monica AI now offer more robust capabilities, faster response times, broader file handling support, and in many cases, at a lower cost — or even entirely for free.The unexpected downgrade in the user experience, combined with the rapid rise of these more effective and affordable alternatives, has made me seriously reconsider renewing my subscription.I share this feedback sincerely and constructively, not out of complaint, but in the hope that the platform will realign itself with the high standards it once set — and maintain its competitiveness in an increasingly dynamic AI landscape.I trust that OpenAI values genuine customer feedback and will seriously consider these insights for future improvements and innovation.After all, in today’s fast-evolving market, customer loyalty is no longer a guarantee — it must be earned, maintained, and continuously respected.
