How they compare
Candy AI is one of the most polished AI girlfriend apps: easy to use, with voice messages, image generation and characters you design yourself. Premium is about $6–13 a month at the time of writing, plus tokens for images and extras, and the free preview is limited.
Kupid's strength is its voice: the most human-sounding voice messages we've heard, with 40+ appearance and personality options and a free tier to sample it. It's one of the pricier companion apps, and the free tier is very limited.
