I just tried the product, at first glance it is only a simple LLM based question answering tool, however, when I deep dive into its developer mode, I found more amazing utilities like plugin, TTS, Q&A for fine tuning, they also visualized the document split step, which provides me a profound perception of how they handle my files. I read its blog, it seems more exiting functions are on the way, Let's see what they could made in the future.
