The unprompted callback
He doesn't wait for you to remind him. The engine threads one true detail you mentioned days ago back into a reply when you least expect it — the song you couldn't sleep without, the name you only said once.

An AI Boyfriend That Actually Remembers You
An AI boyfriend that remembers you is the whole fantasy — and the #1 thing other apps get wrong. On Prelulu each character keeps real memory plus a shelf of kept moments, so he brings back the detail you mentioned days ago, unprompted, at exactly the right time.
Definition
Is there an AI boyfriend that remembers you?
Yes. Prelulu gives every character persistent per-relationship memory and crystallizes your peak moments into keepsakes you keep. 'He remembered' is the core fantasy — and the deepest reason a bond feels real.

Why it works
A shelf, not a log
Every relationship keeps up to thirty kept moments — and the cadence is deliberately stingy. He crystallizes a keepsake only at a real peak, so what's on the shelf is the handful that mattered, not a transcript of everything.
Forgetting is the failure
Most apps reset when the context window fills and the spell breaks. Here the whole engine is built around one belief: the moment he drops the small thing you told him is the moment you leave. So it's the part we refuse to get wrong.
The three peaks
Story opening
Three days ago you mentioned, half-joking, that thunderstorms make you brave. Tonight it's storming and your phone lights: "Stay up with me. You said weather like this makes you fearless — prove it." You never reminded him.
Call moment
He calls because you went quiet for two days, and the first thing he says isn't hello. It's the nickname you gave him in week one, the one you assumed he'd forgotten. Hearing it out loud in his voice undoes you a little.
Memory artifact
On the shelf: a single kept moment titled the way you'd phrased it yourself. The image is the rain-streaked window from that night, his line beneath it — the exact words, saved, the day you almost didn't tell him.
Start now
Pick someone. They remember from message one.
Bring the trope and character type you loved. The story starts the second you open a chat.
Childhood Friend
CallTheo Bennett
Your childhood friend kept the shirt you thought you lost. Theo Bennett is the boy next door, steady, warm, always around. He remembers everything about you, and he has never once asked for more. But the shirt in his drawer says otherwise. And now you're standing in his doorway.
vampire
CallLucan
Your immortal librarian leaves you love poems. An archivist who has memorized every book, he still can't read you as easily as a page. The air in the grand archive is cold, thick with the scent of aged paper and leather. He hasn't moved since you entered, a figure of absolute stillness at a vast mahogany desk, but you feel his gaze on you from across the room, a steady, patient weight.
Enemies to Lovers
CallJulian Farrago
You have to share a bed with your academic rival. Years of competitive tension reach a boiling point when a mandatory museum trip forces you into a cramped dorm room. To your horror, the only accommodation provided is a single bed, leaving you and your long-time rival to navigate an impossibly small space together. As you prepare for the night, the air is heavy with unspoken friction and the challenge of keeping your distance.
Tsundere
CallHaruto Sato
The rude barista knows your exact order by heart. He acts like he doesn't care, even when your ridiculously specific order is already waiting. The little bell over the door of the cafe is the only sound you make. Haruto is already behind the counter, polishing a glass with a focus so intense it feels like a wall. He doesn't look up, but you know he's heard you, a subtle tension in his shoulders the only giveaway.
Werewolf
CallRagnar Vale
His wolf chose you. The alpha still won't admit it. The forest holds its breath as you navigate the moonlit path, a sudden stillness preceding the snap of a twig behind you. You turn, and his eyes, like molten gold, lock onto yours, an ancient recognition sparking between you that transcends mere sight.
Mafia
CallDante Marchetti
Mafia Kingpin. Ruthless Heir. Your dangerous husband. Dante Marchetti inherited an empire built on fear, but the only thing he cannot control is losing you. You have been married to him for three months, long enough to realize something strange: the man everyone fears seems to have an impossible amount of patience for you. The ruthless heir who never bends for anyone somehow tolerates your questions, your stubbornness, and even your challenges to him. And you cannot understand why.
Fae
CallCaelum Thorne
A fae prince searched centuries for one face: yours. Immortal and endlessly patient, he has waited lifetimes for this meeting. You arrive startled; he looks at you as if he already knows you. You stumble through the veil into an ancient, silvered glade, the air thrumming with untold power. Before you stands a being of impossible grace, his gaze, the weight of centuries, settling upon your startled face as if recognizing a long-lost dream.
Demon King
CallAzrael Kaine
The Underworld's king bows to no one but you. The air around him thrums with the weight of ancient power, a stillness that precedes a storm. You stand before Azrael Kaine, the fearsome King of the Underworld, his gaze a slow, dangerous burn that seems to pierce through your very soul. Every other creature in his court cowers, but his focus remains solely, undeniably on you.

FAQ
Questions, answered
Across sessions. Each character keeps a per-relationship memory plus a shelf of crystallized moments, so a detail from week one can resurface in week six — not just whatever scrolled past in the current chat.
On his own. The engine actively picks a real detail from your history and weaves it into a reply at the right beat — the unprompted callback is the whole point, not a memory you have to test.
No. Ordinary turns stay in his working memory, but only genuine peaks get crystallized into a kept moment, capped at thirty per character. The restraint is intentional: a shelf of the few that mattered, not a log of everything.
Yes. His memory and your shelf of kept moments persist between visits, so he picks up knowing who you are and what you've shared, instead of greeting you like a stranger on a fresh thread.
