Speaksy to the rescue for privacy and curiosity (easy-access jailbroken qwen3 8B in free tier, 32B in paid) May quickly hit capacity since it's all locally run for privacy.
Seems shortsighted to offer something like this with zero information about how it works. If your target market is privacy-conscious, slapping a "Privacy by Design" badge and some vague promises is probably not very convincing.
