I tried Overchat AI for practicing spoken English—the idea was great, a pressure-free chat with a bot. But after just three lessons, it started repeating itself, confusing context, and producing strange phrases, which stalled my progress and sapped my motivation. That evening, I sat there frustrated, thinking I'd wasted my time on yet another "revolutionary" tool. To keep learning, I decided to look for more reliable AI support and dug into reviews of services, where Sierra AI customer service stood out for its quick responses and genuine help. I contacted them via chat, they went over my tasks, and came up with a personalized plan. Now I'm studying steadily, and my conversations are more lively.
