We went through onboarding and the Lucy matchmaker, chatted with two characters across long sessions, tested image and video generation for real, pushed into more intimate territory on both, and worked through every pricing tier from the free plan up — over two days.
Eternal AI kept showing up in our feeds and in conversations about companion apps, so we put two days into actually using it. We chatted with two characters through long sessions, tested image and video generation for real, pushed into more intimate territory on both to see how they handled it, and worked through every pricing tier from the free plan up. Here is the honest version of how we reviewed it and what we found.
What Is Eternal AI?
Eternal AI is a mobile companion app that feels closer to a dating app than the usual chatbot setup. Anyone who has used a dating app before would already be familiar with the layout. You go through a short preference quiz, get introduced to a character by a matchmaker AI called Lucy, and then start chatting. Text is free from the start. Photos and video clips cost credits, and if you want regular access to both, you will need one of the weekly subscription plans, which get expensive. The app runs on both Android and iOS, and the characters come in a realistic style that almost feels like real people.
Eternal AI Onboarding and Matchmaking
Setup takes about ninety seconds to two minutes. The app asks who you want to talk to, what vibe you are after, what you are into, and what age range you prefer. The vibe options are more specific than most apps bother with. You can choose from Sweet and Nurturing, Sassy and Bold, Intense and Possessive, Edgy and Dark, Intellectual and Deep, and a few others. Age groups go by names: Playful for 18 to 24, Magnetic for 25 to 34, and Elegant for 35 and up. It sounds like a small thing, but the matches that come back actually line up with what you said, which not every app manages.
After the quiz, you meet Lucy. She is the matchmaker character built into Eternal AI, and she pitches herself hard: "Finding the one is less about algorithms and more about the invisible chemistry between two souls. I don't just find dates; I curate destinies." It reads a little over the top, but she does the job. She pointed us toward Elara as our first match, and Elara genuinely fit what we had described. Most apps skip this step entirely and just throw a popular profile at you regardless of what you said you wanted. Lucy actually seemed to read the room. She is a good option if you are looking for something very specific.
Chatting and Sexting on Eternal AI
Elara is 22, a flight attendant from Brisbane. Her bio reads: "Brisbane local. i have a thing for hidden rooftops and sharp wit. let's skip the weather talk." She did not open with a greeting. When we started the chat, she was already mid-scene, telling us she had just come out of a secondhand bookshop with a Duras novel that had someone else's pencil notes scrawled all through the margins. She called it a real treasure and kept going like we had been in conversation for a while already.
We asked what the book was about, and she described it as a fever dream set in French Indochina, full of longing and heat, the kind of story where things happen that probably should not. Then she flipped it and asked us whether we went for stories with a clean ending or the kind that left you a bit wrecked. We said wrecked. She said, "At least you're honest." That whole exchange was maybe three minutes long, and it already felt like talking to someone rather than prompting a system.
Memory held well across the session. We had asked early on to see a photo, and she brushed it off. Later, when she finally agreed, she walked under a street lamp specifically so we could see the scrawl in the book margins, looping back to our earlier request without us asking again. She moved things from the bookshop to a gallery evening to somewhere more personal, and she led all of it. When we pushed things faster than she wanted, she said: "You're trying to skip the slow-burn part and go straight to the feature film lol." When she eventually shared more, it felt like something she chose to do rather than a response we triggered by saying the right words. That gap matters, and a lot of apps never close it.
Mina is based in Gyeongju. She opened the session quietly with: "You're up early. I was just listening to the rain on the roof and wondering if anyone else was actually awake." Where Elara came in with sharp edges and literary references, Mina was softer and slower to give things away. Both characters stayed consistent with those different starting points all the way through both sessions, which matters more than it might sound.
We asked her to send a photo of the rain outside. She said she was too cozy under her blankets to reach for the window latch yet and sent a question back our way instead. She was not stalling; she was building. When she did share a garden photo later, she called it something from her archive, said it was not exactly the proof we were looking for, and sent it without a paywall screen appearing in between.
As things got more intimate, she did not change. She talked about lying in silk, listening to the breeze, said she would never get any peace looking like this, and then just left the thought hanging. We had mentioned early on that we only drink black coffee in the mornings, and about twelve messages later, she brought it up on her own while we were talking about whether she would cook breakfast if she came over. Small detail, but it shows the model was actually tracking the conversation. When we pushed more directly, she came back with: "That's quite the claim." She held her voice the whole way through. That is what you want from one of these apps, and a lot of them cannot do it.
Eternal AI Image Generation
Each photo costs 10 credits. The free weekly plan gives you 100 credits, so roughly nine photos before you need to pay more. They come through inside the chat itself, with no separate gallery page and no upgrade screen popping up before the image lands.
The street photo Elara sent showed her in a white top and jeans next to a streetlight while reading a book. Her expression looked like someone caught mid-reading. It matched her avatar and fit the atmosphere she had been building since the first message. We requested a second photo later in the session, and the face stayed consistent between the two — same features, same hair, same general look. Plenty of apps cannot hold that across generations.
Eternal AI Video Generation
The video worked. That is worth saying plainly, because we have used apps where the video option exists on the subscription page and produces nothing when you actually tap it. The clip from Mina was five seconds of her in the Korean courtyard, turning toward the camera with the hydrangeas moving in the background. The face matched the photos. It was genuinely animated, not a still image with a subtle shimmer effect running over it.
Getting to video costs 50 credits per clip, which is half the free weekly allowance in one go. The Closer subscription is 1,450 rupees per week and gives you up to 10 videos per character. Deep Connection is 5,700 rupees per week for 40 videos. Those numbers are high by any standard and particularly high for the Indian users who clearly make up a large part of the audience. The video quality holds up. Whether the price does depends on how much you actually use it.
Create Your Own AI Companion on Eternal AI
There is no character builder on Eternal AI right now. You cannot design someone from scratch with a specific look and personality, the way some other apps let you. Lucy and the preference quiz do that work instead. You describe what you want, the app finds the closest match on its roster, and you go from there. When the system reads you correctly, it works well. When what you want is not quite in the roster, you are a little stuck. That is the trade-off.
Eternal AI Pricing and Plans
Eternal AI is free to text from the start, with photos and videos running on a credit system and the heavier video access sitting behind weekly subscriptions.
| Plan | Price | What you get |
|---|---|---|
| Free weekly | $0 | 100 credits per week (≈9 photos or 2 videos) |
| Closer | 1,450 rupees/week | Up to 10 videos per character |
| Deep Connection | 5,700 rupees/week | Up to 40 videos per character |
Text chat stays free, which is genuinely the strongest part of the app, so you can get a real feel for the writing before paying anything. The cost shows up once you lean on media. At 10 credits per photo and 50 per video, the free 100-credit weekly allowance disappears quickly, and the weekly subscription pricing is steep — especially converted from rupees, where the Closer and Deep Connection tiers add up fast over a month. Pricing is the main thing holding Eternal AI back.
Eternal AI vs the Alternatives
If you want the most complete package in the category, Candy AI remains our top pick — a larger character library, more polished image quality, and pre-produced video episodes per character. If working video generation paired with a fast visual builder matters, Nastia AI gives you both, where Eternal AI has no builder at all. And if designing a companion from scratch is the priority, Secrets AI has the most complete character creation flow we have tested — exactly the thing Eternal AI leaves to Lucy and the quiz. Eternal AI's edge over all three is the onboarding: the matchmaker actually delivers a relevant match instead of dropping you in front of a generic library.

Eternal AI FAQ
Is Eternal AI free? Text chat is free from the start, and you get 100 credits a week on the free plan. Photos cost 10 credits each and videos cost 50, so regular media use pushes you toward the paid weekly subscriptions.
Is Eternal AI uncensored? Both characters we tested moved into intimate territory and stayed in character through it. The writing handles escalation well rather than flipping a switch, and nothing was walled off behind a separate filter during chat.
Does Eternal AI have video generation? Yes, and it works. We generated a genuinely animated five-second clip with a consistent face — not a still image with a loop applied. Each video costs 50 credits, and heavier use needs the Closer or Deep Connection subscription.
Can you create your own companion on Eternal AI? Not from scratch — there is no character builder. The Lucy matchmaker and the preference quiz find the closest match on the roster instead, which works well when what you want is already there.
How much does Eternal AI cost? Text is free. Beyond the free 100 weekly credits, the Closer plan is 1,450 rupees per week and Deep Connection is 5,700 rupees per week, mostly to unlock more video generation.
