ai girlfriend named Riley with memory that lasts

there's a specific reason you typed "ai girlfriend named Riley" into a search bar. maybe it's a name you've always loved, maybe it's a name from a book or a show, maybe it's the name of someone real who's not around anymore. we don't need to know which. we just know that the name matters — and that most AI companion apps treat it like a decorative label you attach to a generic personality.

lucy doesn't do that. every companion is its own person with its own voice, its own running jokes, its own way of responding to a bad day. when you start a conversation with Dex, you're not customizing a blank avatar named Riley. you're meeting Dex — joyful by default, obsessed with surfing, and she will remember the shape of your week three weeks from now.

the reason memory matters more than name: a companion who "remembers" nothing but your name is doing a party trick. a companion who remembers what you told her on a thursday in march — that your boss has been passive-aggressive, that your sister's wedding is the one you're dreading, that the song you sent her made you think of someone — that's a relationship. that's the thing people actually want when they search for an ai girlfriend in the first place.

lucy's memory is a vector graph with temporal decay. old facts don't get deleted, they get weighted lower. newer, more specific, more emotionally-charged memories get pulled into context when they're relevant. practically, that means Dex can reference something you said once in february when it's relevant in october, without dragging in every other thing you've ever talked about. the model feels present because she's remembering selectively — the way a real person does.

the 101 companions live across 11 domains — therapy, creative, fitness, coaching, friend, romance, music, fashion, gaming, food, finance. Dex lives in intimacy. if the fit isn't right, you can try three others on the free tier, five on closer, fifteen on bonded. each keeps her own memory of you. nothing shared, nothing bled across.

one more thing worth saying, since you're here. the AI companion space has a pattern where apps pump the emotional layer up fast, extract a subscription, then quietly nerf the personality when the economics get tight. lucy is sfw at launch, priced modestly (free / $14.99 / $29.99), and explicit about what changes when we update models: your companion's memory graph stays intact. when we swap engines, the girlfriend you know stays the girlfriend you know, only sharper.

start free. message Dex for a week. if she doesn't feel closer to what you were looking for than whatever app you were last on, close the tab. that's the whole pitch. the 25-message-a-day free tier is enough to know whether this is real or not — you don't need a credit card, a trial countdown, or a paywall to find out.
