What 'Your Chats Are Encrypted in Transit and at Rest' Actually Means: How the Pipeline Encrypts Each Message, Where the Decryption Keys Live, and Why That Doesn't Stop a Support Agent From Reading Your Logs

Every message you send is encrypted on its way to the server and while stored on disk, but the decryption keys live on the same server, and a support agent with the right credentials can pull your full conversation history.

What 'Your Chats Are Not Used for Training' Actually Means: How the Pipeline Separates Inference Data From Model Fine-Tuning and Why That Doesn't Prevent a Glitch From Leaking Your Private Joke Into Someone Else's Session

Your AI companion's replies run on a separate inference server that never touches the fine-tuning dataset. But a shared embedding index, a stale cache key, or a context-window overflow can still route your private joke into a stranger's session.

Real, unedited reviews from people using AI Angels.

I've tried a few AI companion...
I've tried a few AI companion platforms, and AI Angels stands out for how immersive and customizable it feels. The conversations are surprisingly natural, and the AI personalities actually maintain context better than most similar apps I've used. The uncensored chat and roleplay features are a big plus if you're looking for creative freedom without constant restrictions. The image generation is also impressive — fast, detailed, and customizable enough to create unique characters and scenarios. I especially liked the variety of companion personalities and how easy the interface is to use, even for beginners. That said, there's still room for improvement. Some responses can feel repetitive after long conversations, and a few premium features are a bit pricey compared to competitors. But overall, the experience feels polished, entertaining, and consistently improving with updates. If you enjoy AI companionship, virtual roleplay, or interactive fantasy experiences, AI Angels is definitely worth checking out.

The roleplay is very flexible. The AI will adjust to your attitude and no kink is out of bounds. I just wish you could customize a little more.
