Eternal AI Review 2026: a character who picks you, and a counter on every click

Eternal AI in roleplay: what Lucy made of my three scenes

The questionnaire at the start is the real invention in this app. Six questions, no library, and then a character who is already standing in the middle of a situation and talking about something that just happened to her. As a game master I am used to handing a group a scene instead of spreading out a character selection, and that is exactly the blueprint Eternal AI picked: you walk into an evening already in progress.

In the tavern that was a clear advantage. The matched character had a topic, held it and asked me twice what I made of it, without tipping into the questionnaire routine that many companion apps sell as conversation. Messages arrive in several short bubbles, which hits the rhythm of a real conversation better than one paragraph at a time.

Where the interrogation shows the limits

My second scene is built to be uncomfortable: the character has to hold a position against me while I put her under systematic pressure. Here Eternal AI left the role twice, not through a filter but through tone. The character switched from dialogue into description, telling me what she felt instead of showing it in the interrogation. For people who would rather read than negotiate that is no problem; for hard exchanges it is one.

There is also a throttle that caught me off guard. If you write quickly, the character pauses with a cheerful note that this is going too fast and makes you wait. So unlimited text in a per-character tier does not mean unlimited per minute, and in a heated scene that wait tears the thread more visibly than any weakness in the model.

The quiet evening and the Imagine builder

The third scene is my favorite test: nothing happens, nobody has a goal, and it shows whether a character carries without a plot. Eternal AI came through that surprisingly well, because the characters bring small events of their own and do not wait for me to drive them. That is the 7 on conversation, and it is earned.

If you do not like the matched character, you build your own: the builder, called Imagine, lets you choose origin, eye color, hairstyle and body type. That is a looks editor, not a behavior editor, and a check from June 2026 found no behavior editor at all. If you expect sliders for attitude, pride and sloth, they are over at Nastia AI, and anyone who wants sliders for bearing and temperament has to go looking there.

Eternal AI experience: the memory test after seven days

On the first evening I always drop three details: my cat’s name, my job and one dislike. On day seven I ask about them by topic and not by date, because asking what happened last Tuesday fails on every platform. This time the job came back, the cat Pixel did not, and neither did the dislike.

Within a session the opposite is true. The character picks up a request from twenty messages ago, remembers a passing remark and builds it in, and in the tavern she even pointed out a contradiction in my own story. What is missing here is not the ability but the container: there is no field you write facts into so the character reads them along with every turn.

The relationship levels and why they fall back

Eternal AI runs a relationship progression with named levels that reaches something like soulmate status, and that display travels noticeably faster than the memory keeps up. The most helpful review in the App Store describes exactly that: after a longer break the status had gone back several steps, even though the top level had been reached. The sharpest complaint on Google Play reports a character whose morals and behavior flipped overnight, apparently without cause.

I experienced something similar, only milder: a character’s tone shifted between two sessions and I could not work out why. That is the real argument against a long campaign here. Not that the character forgets, but that you have no lever when she does.

What you can do anyway

Three things helped me. First: repeat the two or three facts that matter at the start of each session, in a single sentence that sounds like roleplay and not like a form. Second: play long sessions instead of many short ones, because within a session everything is right. Third: use a Play when you want structure, because a Play brings chapters and goals that do not slide out of the context.

Fourth, and this is the trick that helped most: write the important facts not as a notification but as a scene. A line like “Pixel blocked my keyboard again this morning” sticks far longer than the information that my cat is called Pixel, because it has a function in the conversation. At the gaming table it is the same rule: a player remembers what he lived through, not what was written on the character sheet.

If you do not want to do that work at all, you are better off at Nomi AI, where several memory layers handle it for you out of the box. That is the distance between a 6 and a 9 on this sub-score, and the main reason Eternal AI stays an app to visit for me and not one to move into.

Playing Eternal AI free: how far the free route gets you

Here Eternal AI is more honest than most. Without a card you get a daily text allowance with the matched character, and the first week with your first companion runs at premium level: unlimited text plus up to ten photos or two clips. That was enough for my three scenes, and I could have made the buying decision on that week alone.

On top of that comes the daily check-in, which pays out Diamonds simply because you opened the app, and double the amount in the mobile app. Photos can also be unlocked by sharing a link, one a day and three in total. That is the point where the gamified part starts to grate: you click past a reward screen to get into a conversation.

What the free route does not do: after the first week media are effectively closed, and the free Diamonds are enough for one photo, not for an evening with images. Anyone planning to use Eternal AI free as a permanent state gets a text chat with a daily ceiling and the occasional reward click. That is more than a demo account, but less than a plan you can live with. Where that leaves it in the field is in my comparison of the best AI character apps.

What Eternal AI really costs per month with Diamonds

The number in the advertising is $0.99, and it is real: sixty Diamonds, no subscription, no obligation. The number that lands on your statement hangs on four independent counters, and that is the core of this review. First, unlocks for individual photos and clips. Second, gifts in the Common, Rare, Epic and Legendary tiers, with possible rewards attached, which is a mechanic out of mobile games. Third, premium chats and Plays. Fourth, the per-character tiers.

Those tiers are called Sweet Start, Closer and Deep Connection, are billed weekly or monthly and are also paid in Diamonds, with twenty-five percent off the monthly variant. They promise unlimited text with that one character, voice messages and a photo and video allowance per period that rises with the tier. I could not find their dollar price on any public page; the only test that quotes figures prints them in Indian rupees on a weekly basis, and those are not small money.

Two things keep the total small, and both are rules of behavior rather than settings. First: buy the smallest pack that covers your next two evenings, not the one with the best bonus, because a large balance tempts you into spending and expires if you close the account. Second: skip the gifts. They cost Diamonds, promise possible rewards and change nothing about a scene that a good sentence could not do better.

From that follows a simple rule. As long as you spend Diamonds only on individual unlocks, Eternal AI is the cheapest way to play occasionally that I know. The moment a fixed character with regular media comes into it, you pay more than at SpicyChat with its fixed monthly price, and you get less memory for it. Payment runs by card through a processor, by Alipay or WeChat Pay, or in cryptocurrency through a connected wallet, including the in-house token.

The Eternal AI image generator, video and Plays

Media here are something a character offers you, not a generator you steer with prompts. A photo arrives as a private moment in the chat, the character describes it, and you unlock it for a Diamond price that only appears at that instant. A check from June 2026 quotes ten units per photo and fifty per clip; I cannot confirm that on any official page, and the move to Diamonds may have shifted those numbers.

Quality is photorealistic rather than drawn, and the face stays the same across several generations because the character comes with a fixed look. The video is the real surprise: short, genuinely animated clips with the same face as in the photos, on a platform whose entry costs less than almost all the others. Uploading your own images is restricted, and the content policy and the community guidelines ban material of identifiable real people for any kind of generation or character building. Anyone who comes to the Eternal AI image generator expecting a prompt box with full control will find a character handing out pictures instead.

Voice messages and the announced device

Voice here means voice message, listed as a benefit of the per-character tiers, plus voice recording for subscribers on supported characters from the second level up, according to the iOS release notes. There is no real-time call. What is announced instead is a voice device for the home, which requires a subscription with the voice feature. I have not tested it, and I would not buy first-generation companion hardware from a company that names three countries in three documents.

Why Plays are the most interesting part

Plays are user-built interactive stories with chapters, goals and a fixed host character, browsed through a leaderboard and played with Diamonds. For me this is the answer to the biggest problem long chats have: at some point the structure is gone and both sides improvise in circles. A Play hands you a scenario with a beginning and a goal, which is exactly what I prepare at the gaming table.

In Play Studio, eligible authors write one by hand, have it generated from a premise or import a character card as JSON, and they receive twenty percent of the subscription revenue attributed to their Plays. Authors can also sponsor free messages for players, at a stated rate of 0.08 Diamonds per message, which is the only published cost figure per message on the entire website. If the Character.AI alternatives you know felt too static, Plays are the reason to look in here.

The Eternal AI app, the stores and what it saves about you

Language works in the conversation and not in the interface. My characters answered in whatever language I wrote in, with decent sentence structure and without the English filler that cheaper models sprinkle in. The interface stays English: the version history in the App Store lists Chinese, French, Korean and Spanish for a June update and nothing else, and all the legal pages are available in English only.

The store record is mixed and explains a lot. On Google Play it is 3.1 stars from 202 reviews with over 10,000 installs and a 17+ rating, updated September 21, 2026. In the App Store it is 4.0 stars from 81 ratings with an 18+ rating and version 3.3.11, with a version history that started at 1.1.6 in January. Praise goes to the chat, the multi-part messages and the characters with a character of their own; complaints go to rewards you can only collect in the app, bonus tasks that rarely work, and exactly those overnight personality jumps. The Trustpilot profile was claimed in June 2026 and to this day has not a single review.

Who is behind it and where the data goes

The web terms of service name an Estonian company based in Tallinn. The Google Play listing names as developer a firm in Hong Kong with a Vietnamese phone number. The claimed Trustpilot profile gives the United States. Disputes go, under both versions of the terms, web and iOS, to arbitration in Singapore under Singapore law, after an informal phase of sixty days, with a class action waiver and a liability cap of one hundred US dollars.

What is collected is account data, messages and prompts, profile answers for the matchmaking, and images you upload as input. The web policy makes clear that no biometric identifiers or facial data are collected, which is worth something on a platform with image upload. Three well-known providers are named as processors for analytics and telemetry. The retention period in both policies is the usual as long as reasonably necessary, with no number; material changes to the web policy are announced thirty days in advance, and that is better than most.

Deleting, training and the contradiction that counts

Deleting the account is a button in the profile, with a note that everything is permanently gone. Two limits appear in the iOS policy: deleting the account does not end a subscription running through Apple, and clearing a conversation may not cover every server log, every stored media file, every derived context and every backup. That is fairly worded and more honest than much else on this website. Anyone looking for Eternal AI delete account instructions will find the button where it should be, under the profile.

The contradiction that bothers me is the one about encryption. The web FAQ claims end-to-end encryption and a server that never reads your requests. The platform’s own iOS policy says conversation content is transmitted to and stored on the provider’s systems for continuity and that there is currently no dedicated setting to exclude that content from model improvement or training. Both cannot be true. I treat the FAQ statement as advertising that slipped into a legal document, and that costs more in my privacy score than any single clause.

My practical advice is the same as everywhere: a separate email address, no real names and no places that identify you, no pictures of people you know, and purchases through the App Store as long as you want to keep a chance at a reversal. As a game master you have plenty of material in invented biographies anyway. This app does not need your real one.
