What JOI AI actually is
JOI is a sexting app with a storefront feel. You browse characters by taste, open a chat and things get filthy fast. On top of the chat sit two tools: an image generator and a video generator that start from a base character and a short prompt, in realistic, anime or 3D styles.
The video tool lets you pick the orientation and make 1, 2, 4 or 8 clips at once. Neat for a chat app, but it is a side dish, not the main course.
Pricing and the catch
We could not find a single price on JOI's public pages. The terms describe Premium, a subscription billed monthly, quarterly, half-yearly or yearly, plus Neurons, the coin you spend on spicy content. Reading one romantic message costs 4 Neurons, a photo view up to 120 and a video view up to 1,900.
Some characters also sell their own add-on subscription, which only works while Premium is active. That is three meters running at once. The upside: unspent Neurons can be refunded within 14 days.
Our verdict
Fun if chat is the point and you like a curated cast. If you came for the videos, the Neuron meter gets expensive fast. Fapinyo turns a still into a clip directly, gives you 35 free credits to try it, and its one-time plans start at $13 with no subscription.
