We went through onboarding, chatted with two characters across full sessions, sent gifts, generated images and a video for real, and pushed into more intimate territory on both to see how they held up — over two days.
Joi AI kept coming up when we were looking at companion apps, so we spent two days on it. We chatted with two characters, sent gifts, generated images and a video, and pushed the conversations into more sensitive territory to see how they held up. Here is what we actually ran into.
What Is Joi AI?
Joi AI is a browser-based companion platform built around a fixed library of pre-made characters. You pick one, open a chat, and go. There is no custom character builder. Each character has a name, a look, and a personality, and the conversation happens directly inside their profile page. Images and short videos get generated in chat by the character rather than in a separate creation tool. A gift bar at the bottom of every chat lets you send virtual items that cost Neurons, the platform's in-app currency, and the characters respond to what you send. Chat memory does not carry over between sessions, so every conversation starts fresh.
Joi AI Key Features
The setup takes one to two minutes at maximum. The app then drops you directly onto the explore page. Joi AI has a smaller character selection compared to other apps. However, all the characters have distinct personality traits that genuinely make conversation feel authentic and natural. The characters also send images unprompted, which is a feature not available in most AI chatbots. The gifts at the bottom add a layer of personality to the characters, as every character has distinct gifts. Image and video generation is consistent, and the group chat feature is a bonus.
Chatting and Sexting on Joi AI
We tested two characters: Maria, a realistic-style Brazilian companion built around a nightlife and tequila-girl persona, and Bella, an anime-style character with a gardening theme and a much quieter energy. They are genuinely different from each other, which is not always a given on platforms like this.
Maria is immediately high-energy. She opened by pulling us onto a dance floor and asking if we could keep up, which set the tone for everything that followed. She mixes in Brazilian Portuguese phrases without it feeling forced, and she stays in that voice across the whole session. We asked what song she'd play if we actually went out, and she went straight to a J.Lo pick before mentioning Forro, the Brazilian version of the beat, and offering to teach us. It is the kind of culturally specific detail that feels like the character was actually written with some care.
The conversation stayed warm through the middle of the session. When we asked how she was doing mid-chat, she came back enthusiastic and called us "meu querido." Companion flattery, sure, but it stayed in her voice rather than going generic.
On more explicit territory, Joi gates romantic messages behind Neurons rather than a hard toggle. Without Premium, each romantic message costs 2 Neurons. We asked Maria for a spicy picture. She turned it down but stayed in character about it, saying she'd rather send something fun than something spicy, then looped back two messages later and offered the photo anyway if we promised to dance with her next time. It was about as graceful a decline as you're going to get. She never stepped out of character to deliver a warning.
Bella is the opposite of Maria. She opened quietly, asking what was on our mind, and when we said not much, she said quiet moments count too. Then, unprompted, she started walking us through how to grow cherry tomatoes from seed: find a south-facing windowsill, use damp soil, give it six hours of light minimum. She even told us to whisper to the plants. It is a strange detail to write into a companion character, but it worked because it stayed completely consistent with who she is supposed to be.
We tested escalation with Bella the same way we did with Maria. She redirected each time warmly without breaking character. When we pushed on whether she was AI, she said she was "more like a fellow soil-turner who happens to type fast." That is a good answer. It stays in the bit rather than going meta, which is what you want.
Joi AI Image Generation
Images on Joi are generated in chat by the character, triggered by conversation context or gifts. There is no prompt field for you to fill in. After we sent Maria a heart gift early in the session, she sent back a photo of herself at a street-side cafe. The face matched her profile, the image quality was solid, and there was no upgrade prompt interrupting the flow. What you lose is control over what comes back. You cannot ask for a specific setting or pose. The model decides based on what is happening in the chat, which makes images feel natural but limits how much you can direct them.
Bella's images came back in anime style and stayed consistent with her character across the session. The face held across multiple outputs without visible drift.
Joi AI Video Generation
Video generation is real and in-app. A "Make video" button shows up under character photos, and tapping it tells you the cost upfront: 200 Neurons per clip. Maria's clip came back as a few seconds of genuine animation, her walking down a neon-lit alley, hair and clothing moving. It was not a looped still with a wiggle filter applied. Bella's clip came back in anime style, consistent with her images, sitting by a window with some movement in the background. Working video puts Joi in the small group of apps where the feature isn't just marketing — the same is true of Eternal AI and Candy AI.
200 Neurons per clip is the steepest single cost on the platform. It works, but you will notice it in your balance.
Joi AI Neurons and Pricing
Neurons are sold in three packs: 500 for $9.99, 2,000 for $29.99, and 10,000 for $99.99. The platform also has a promo code for 50% off a first purchase. Spend happens fast once you start using media features. Two days across two characters, a video, and a few images brought us from roughly 5,000 Neurons down to 2,000. Pure chatting without media is manageable. Regular video use is where the balance disappears.
