Been really using Venice. UI is clean, I like the live counter while waiting for replies or images, it's small but useful. The replies come in fast without the usual filters you see elsewhere. It's more to the point, feels casual and doesn't waste your time. Good pick if you just want something straightforward without the privacy trade offs.

I just started using Hoody AI, and it's quite amazing in every aspect! What stands out immediately is their focus on privacy. They offer anonymous payments, IP and fingerprint protection, encrypted instances, anonymous usage. You can tell they addressed privacy concerns around AI very seriously. I love that my chat history cannot be traced to me in any way. Their interface is user-friendly and provides unlimited access to the most popular AI models like Claude 3.5 Sonnet, GPT-4 mini, Llama 3.1 405B, etc..., and the cool thing is, they can all be used at the same time! Most AI features are included: file uploads, voice interaction, text-to-speech, and so on. In short, another excellent AI discovery thanks to TAAFT!
