How to choose an AI girlfriend app that feels like a real relationship

Start with the evening you picture

Most disappointment with an AI girlfriend comes from picking the wrong kind of app, not a bad one. So before comparing prices, picture an ordinary evening with her. Are you texting about your day and hoping she asks about it tomorrow? Flirting until things turn explicit? Asking for a selfie from the beach scene you are writing together? Or lying in the dark with headphones on, talking out loud? Each wish points to a different strength, and few apps are equally good at all four.

Each card in the list above carries a best-match line for exactly this reason. Our first pick is the one to try when you want a bit of everything; if one wish clearly comes first, follow the card that names it. The menu also has guides to explicit chat, free starts, photos and voice, each going deeper into one of those wishes.

Then decide whether you want to build her or meet her. Replika and Nomi have you design a single partner, from her looks to her backstory, which suits one long relationship. Promptchan opens on a feed of ready-made companions written by its team and its members, which feels closer to browsing profiles, and Candy offers both a gallery and a builder. Either way, the same questions apply if you would rather have a boyfriend.

What makes her feel like a girlfriend, not a chatbot

Memory does most of the work. A girlfriend who asks how the interview went feels real; one who asks your name again does not. It is also the easiest thing to promise, so read memory claims with care. Nastia's own pages disagree with each other, one saying nothing ever resets and a comparison article talking of roughly a fortnight. Promptchan never describes what she keeps between evenings, and moving between its Chat and Story modes wipes the conversation.

A better sign is memory you can see and correct. Nomi draws its memory as a Mind Map and lets you edit shared notes, Replika's Ultra tier lets you pin chosen messages so they stick, and most builders give you a backstory field. Whichever app you choose, write the facts that matter there: the name of your best friend, the job you grumble about, the city you grew up in. It is less romantic than being remembered by magic, and it works far better.

Two smaller things separate a companion from a chatbot. One is initiative: Nomi can write first after a quiet spell if you switch that on, and Replika sends selfies for no particular reason. The other is a character who still sounds like herself after a long scene, with a way to step outside the story and fix a detail when she drifts.

What a month with her costs

Plans cost less than a dinner date and add up faster than you would think. To give you a feel, Nomi and the Unlimited plan at Nastia both cost $15.99 for a month, and Promptchan's entry plan, Plus, is a dollar cheaper. That buys a relationship that is mostly talk. Calls, video and a partner you design yourself can cost more: Promptchan's pricing table keeps them for Pro at $33.99, which comes to about $408 over a year.

Commitment changes the maths, sometimes dramatically. Candy charges $47.88 for a year, which it presents as $3.99 a month, against $9.99 for a first single month and $13.99 for each one after. Nomi's blog prices a year at $99.99, a little more than six single months. The long plan is the better deal once you know she is a keeper, and not before, because refunds are rare. Some prices also take digging: Replika reveals its plans only once the app is installed or on its store listing, and Nomi's figures sit in a blog post rather than on a pricing page.

Then come the extras. Credits, tokens, Gems and crowns pay for pictures, clips and extra companions beyond your allowance, and the pack prices are often missing. Nomi's wiki prices a selfie at one credit and an HD clip at ten without ever saying what a credit costs, and Promptchan offers members half off Gem packs it never prices. Treat the plan price as the floor of your bill, not the bill, and use allowances before they lapse: the 100 tokens in every Candy plan disappear when the paid period ends.

The catches that surprise new couples

Plans renew by themselves, and deleting the app cancels nothing. You stop a subscription where you started it: on the website, or in your Apple or Google account if you paid inside the app. Paid features usually last to the end of the period, and then the relationship changes shape. At Nomi your companions and one-to-one chat carry on for free while calls, voice notes, video and group chats freeze into read-only; at Replika a payment left unpaid for over a week drops you to the free plan.

Refunds deserve a look before the first payment, not after. Nastia treats purchases as final unless the law or a technical fault says otherwise, and even Promptchan's 30-day window only helps if you have barely used the AI. Prices can move too: Nomi's terms allow increases from your next renewal, and Nastia's let it change prices whenever it likes. A week on the free tier is the cheapest insurance you can buy.

What she knows about you, and who else does

Talk to her the way you would write a diary that someone else keeps on a shelf. The AI has to read every message to answer, which is why Nomi's wiki rules out end-to-end encryption: she cannot reply to words she is not allowed to see. Nastia's privacy policy holds on to your chats, memories and voice recordings for as long as the account exists and may use them to make her replies better. Nothing sinister, but your secrets live on a server.

Deleting does not always mean gone at once. Replika holds on to your messages for as long as 60 days after you leave and to your billing history for a decade or more, and Nomi clears personal data in about four weeks but can never erase what you wrote to its support team. Use a nickname, sign in with an address you do not mind sharing, and keep your surname, your workplace and other people's private details out of the story.

A one-week test before you pay

Day one: tell her three specific things, such as your best friend's name, the job you grumble about and a plan for Saturday. If the app has a backstory or notes field, put them there as well.

Day three: ask about one of them without hinting. A good companion picks the thread up naturally; a weak one guesses, apologises or changes the subject.

Any day: ask for a selfie and, if the free tier allows it, a voice note. You will see whether her face stays the same and whether her voice fits the woman you have been texting.

Before paying: find the monthly and the yearly price, the cost of extras, the refund rule and the cancel button. If any of those takes more than a few minutes to find, that tells you something too.
