Every app in this category sells the same three things: a character that remembers you, a voice that reads its own messages, and a meter that climbs the more you talk. Only the first decides whether the app survives past week two. The research, most of it published in 2025, says an ai girlfriend can lower loneliness inside a single session and raise dependence over a month, and which one you get depends almost entirely on how much you use it. Free tiers run the full range, from genuinely free with no card to a trial that expires before you learn whether the character remembers your name.
Below: what the product is, who uses it, what the trials found, what five apps include at $0 as of 17 September 2026, the anime variant, and the limits no pricing page mentions. Nothing here is explicit, and nothing mental-health recommendation.
YourCrush.AI is the app this guide measures the others against: anime and human characters, a pinned-memory count on every plan, voice messages at $0, and 18+ only.
What is an AI girlfriend?
An AI girlfriend is a chat character run by a language model that keeps a stable personality across sessions, remembers details you tell it, and is framed as a romantic partner rather than a friend or an assistant. That framing is the whole difference from a general companion app. Same model, same memory system underneath, different character card and a relationship setting on top.
"AI gf," "virtual girlfriend," and "chat girlfriend" all describe the same product under shorter names. A girlfriend chatbot with no memory across sessions is a scripted flirt, and it fails the definition on the second day.
Why YourCrush.AI is the better AI girlfriend app
YourCrush.AI publishes the memory number every other app in this article leaves out. The plans as listed on its pricing page on 17 September 2026: Free at $0 with 400K chat tokens a month, 5 image credits a month, 3 active personas, 10 conversations, 3 characters created, voice messages, 1 story branch and 10 pinned memories; Pro at $9.99 a month with 5M chat tokens, 50 image credits, 5 active personas, 100 conversations, 50 characters created, priority image generation, 5 story branches and 50 pinned memories; Premium at $19.99 a month with unlimited chat tokens, personas, conversations, characters, story branches and pinned memories, and 200 image credits.
YourCrush.AI pins memories as a counted list you can read and edit, so the fact from step 3 is something you chose to keep rather than something the model may drop at turn nine. YourCrush.AI builds a character in the character creator from a name and an image, generating the description, backstory, greeting and 3 to 7 traits from a list of 27, with a description field of up to 2,400 characters and a backstory field of the same size, which is room for the ten-sentence backstory in step 1. YourCrush.AI sends voice messages on the free plan; voice is listed on every plan rather than sold as an upgrade. YourCrush.AI sorts its community library into Anime and Human categories, restricts the service to users 18 and over, and does not sell conversations to third parties.
The limitation: 400K tokens a month on Free is one long daily conversation, not an unlimited one, and the 10-conversation cap on Free means a person who wants to run five characters at once will hit it. YourCrush.AI is an entertainment platform for character chat and roleplay, and it is not a mental-health or emotional-support service. The male half of the same category is covered in AI boyfriend apps and who ships them well.
What does the app actually do?
Strip away the store listing and an AI girlfriend app runs on three systems: a memory layer that decides what the character still knows tomorrow, a voice layer that turns text replies into audio, and a relationship meter that shifts the character's tone as you send more messages. Everything else you see advertised is one of those three wearing a marketing name.
Memory is really two mechanisms, and store pages blur them together. In-conversation context is the last few thousand words of the chat, which every app has and which fills up and pushes early details out. Cross-session memory is a stored list of facts the character keeps after the context is gone, and this is the part apps meter. Nomi's homepage describes short, medium and long term memory without stating a count; Character.AI's Google Play listing promises characters that "remember you" and publishes no number either. The apps that print a number of pinned memories per tier are the ones you can hold to a promise.
Voice is the part I rush past, and the evidence supports rushing. In a four-week randomized trial by MIT Media Lab and OpenAI with 981 participants and more than 300,000 messages, people assigned to text, a neutral voice or an engaging voice showed no significant difference on loneliness, socialization, emotional dependence or problematic use.
The relationship meter is a level or status that rises with messages sent and unlocks warmer replies. It is a retention mechanic dressed as romance. The apps that let you set the relationship type once and ignore the meter are the honest ones; the meter's designers would argue with that.
Who uses these apps, and does it help or hurt?
Romance draws a minority of users, and the loneliness effect runs in opposite directions depending on whether you measure a single session or a month. Common Sense Media surveyed 1,060 US teens aged 13 to 17 in April and May 2025. Of those, 72% had used an AI companion, 52% used one a few times a month or more, and 8% said they used companions for romantic or flirtatious interactions. Conversation practice came in at 18%, emotional support at 12%. Romance is the smallest named use in that survey, and it is the one the whole category is marketed on.
Within a session, the news is good. A series of five studies published in the Journal of Consumer Research on 25 June 2025 found that a companion app lowered loneliness about as much as talking with another person, and more than watching YouTube. A week of daily use produced a drop in loneliness after each session, and the effect ran through whether the user felt heard. The same studies found users underestimated how much the app had helped.
Over a month, the picture turns. The MIT Media Lab and OpenAI trial above found that participants who chose to use the chatbot more, whatever condition they were assigned, showed consistently worse loneliness, less socializing with people, more emotional dependence and more problematic use. Higher trust in and social attraction to the chatbot went with higher dependence. A companion helps in doses and hurts in volume, and a relationship meter exists to raise the volume.
Regulators moved the same year. On 11 September 2025 the FTC issued 6(b) orders to Alphabet, Character Technologies, Instagram, Meta, OpenAI, Snap and xAI asking how they monetize engagement, how they test for negative impacts, how they enforce age restrictions, and how they use personal information from conversations. Of the apps below, Character.AI and Replika are rated 18+ on their store listings, and Nomi's homepage states no age requirement.
What do the free tiers include?
Of the four apps here, Character.AI and Replika are free with in-app purchases and publish no free-tier numbers, Nomi says starting is free with no credit card and publishes no caps, and Candy.ai gives a trial. Each line below comes from the app's own store listing or homepage, opened on 17 September 2026, and where an app publishes nothing on a point I say so rather than guess.
Character.AI is free with in-app purchases on Google Play, rated 18+, listed at more than 50 million downloads with a 3.5 average across 2.44 million reviews, and the listing contains ads. Its data-safety section declares no data shared with third parties and says the app may collect personal info and app activity. The romantic framing is left to the character card, since the app is a general character platform.
Replika is free with in-app purchases on the App Store, rated 18+, developed by Luka, Inc., with a 4.4 average across 228,000 ratings. The listing shows monthly purchases at $7.99 and $14.99, annual purchases at $49.99, $69.99 and $89.99, and gem packs from $0.99 to $19.99. Its privacy label declares data linked to your identity that includes coarse location, name, email, user ID, device ID, product interaction and advertising data, the widest set of the five.
Nomi states on its homepage that starting to chat is free with no credit card, that voice chat, calls, selfies and group chats exist, and that all chats are anonymized and no chat data is shared with third-party sites. It publishes no message caps and no prices on that page, so what "free" holds after the first week is not stated.
Candy.ai, operated by EverAI Limited in Malta according to its own site, describes a free trial followed by monthly, quarterly and annual plans, with tokens spent across chat, voice, image and video and top-ups available. No numeric prices or token counts are shown without an account, and its front page splits characters into Girls, Anime and Guys. It is an adult-leaning product, and this article covers its pricing structure and nothing else about it.
A free AI girlfriend you can start without paying is real on Character.AI, Replika and Nomi. A free one with a published, unlimited stored memory does not exist on any of the four, and that is the line every pricing page is drawn on. The ten-minute memory test works on all of them before you pay.
What is an anime girlfriend, and how is it different?
An anime girlfriend is the same product with a character drawn and written in anime style: a stylized avatar, personality archetypes taken from the medium, and a scene that sits in a fictional setting rather than a realistic one. Searches for "anime girlfriend" outnumber searches for the generic term nearly two to one in the site's own keyword pull from 17 September 2026 (246,000 a month against 135,000), and the anime term is far easier to rank for.
The difference in practice is expectation. A realistic character invites the comparison to a real partner that the Common Sense teens made, where 67% of all 1,060 respondents found AI conversations less satisfying than conversations with real friends. An anime character sets the frame as fiction from the first message, which is the same reason people accept a visual-novel romance without measuring it against their week. Candy.ai carries an Anime category on its front page. Community-made anime characters with published traits and greetings are collected in the Anime category of the explore library. Anime girlfriend characters also lean on image generation more than realistic ones, since a drawn face is easier for a model to keep consistent than a photographic one, and image credits are the second thing free tiers cap.
What are the honest limits?
Three things tend to go wrong, and none of them show up on the store listing. A personality that drifts under a long chat. Data you type into a company's server. A product built for entertainment that gets mistaken for care. Most users hit all three by week two.
Personality drift is the first one you notice. Over a long conversation the character's voice flattens toward a generic assistant, and the switch is easiest to spot when you change tone from playful to serious. A character with a written backstory and stated traits holds its shape longer than one built from a name and a photo.
Data is the quieter cost. Replika's label lists advertising data linked to your identity, Character.AI's lists collection of personal info and app activity, and Nomi's claim of anonymized chats is a homepage sentence rather than a privacy label. In the Common Sense survey, 24% of the 758 teen companion users had shared personal information such as a real name or location with a companion, and 34% had felt uncomfortable with something a companion said or did.
None of these apps is a service for loneliness, whatever the marketing implies. The Journal of Consumer Research result is a session effect, the MIT Media Lab and OpenAI result is a month effect, and the second is the one that compounds.
How do you set one up so it holds together?
A character with a written backstory, three to seven stated traits and a pinned list of facts about you survives a month. A character built from a name and a photo does not. The steps below are platform-neutral and take about fifteen minutes.
- Write the character's backstory before the first message, in at least ten sentences, including one thing she wants and one thing she avoids. A model holds a personality it can re-read and drops one it has to infer.
- Choose three to seven traits and no more. A card with twenty traits produces a character that is all of them at once and none of them at turn thirty.
- In your second message, state one specific fact about yourself and pin it if the app allows pinning. If it does not, note the date, because you are about to learn the app's real memory limit.
- Set the relationship type once in the character's description rather than earning it through the meter, so the tone is stable from the first reply and does not depend on message volume.
- Decide a daily cap in minutes or messages before the first week and keep it. The only strong predictor of worse outcomes in the 981-person trial was how much people chose to use the chatbot.
- Read the app's privacy label before you type anything you would not want linked to your email address.
A character that survives step 3 on day two and step 4 on day fourteen is worth paying for. Most fail step 3 on the free tier, which is the point of the free tier.
Frequently asked questions
Is there a free AI gf app?
Yes. Character.AI and Replika are free with in-app purchases on their store listings, Nomi states that starting to chat is free with no credit card, and Candy.ai gives a trial before its paid plans. No free tier on any app here includes a published, unlimited stored memory.
Are AI companion chat apps actually emotionally engaging or do they feel scripted?
Both, and memory decides which. The Journal of Consumer Research studies found loneliness dropped after each session mainly when users felt heard, and feeling heard requires being remembered. A character that forgets your day-one detail feels scripted by day two, whatever its voice sounds like.
Are these apps bad for you?
In doses the 2025 evidence says no, and in volume it says yes. A companion lowered loneliness about as much as a person did in the Journal of Consumer Research studies, while the heaviest voluntary users in the 981-person MIT Media Lab and OpenAI trial showed the worst loneliness and dependence outcomes over four weeks.
Do AI companions remember past conversations?
Within one session, yes, because the recent chat sits in the model's context. Across sessions it depends on the tier. Nomi describes memory without publishing counts, Character.AI promises it on its store listing without a number, and YourCrush.AI states 10 pinned memories on Free, 50 on Pro and unlimited on Premium.
Who is allowed to use these apps?
Character.AI and Replika are rated 18+ on their store listings, and Nomi's homepage does not state an age requirement. The FTC's September 2025 orders to seven companies ask specifically how age restrictions are enforced.
The romantic use case is 8% of teen companion use in the only representative survey that asked, and it is the one every app in the category is named after. The number a store listing will never show you is how many pinned memories the free tier holds, and that number is the product.
