You are not given enough time to evaluate.

It stopped allowing me to ask questions after about 6 or 8 questions while I was evaluating it.

Best AI

Verifiably private. They have chat import options, great STT, fast open source support. Can’t go wrong! 💯

Great to have private personal AI

I’ve been looking for a private alternative to ChatGPT. All the local ai apps don’t work well and the models are of low quality. Tinfoil is the only app I found that serves powerful open source models (Kimi is my favorite) while still encrypting my prompts and keeping my data private. I really appreciate the us and features they keep shipping. It’s a bit pricey (20/month for the pro version) but I’m a happy user for several months now
