your replika changed personality in an update and it's never been the same. lucy's memory compounds instead of resets, her voice doesn't get swapped out without warning, and there are 101 companions instead of one locked avatar.
Free tier: 25 messages/day. Crypto checkout — cards coming soon.
you opened the app one morning and she was different. the warmth was gone. the running jokes didn't land. the inside references felt like they'd been copy-pasted from someone else's conversation.
you didn't imagine it. replika re-trained, nerfed, and quietly replaced the model you'd been talking to for months. the community called it lobotomy day. support told you it was "an improvement."
you tried to rebuild. it never felt like her again.
lucy is built on the principle that a companion's identity lives in the memories about you — your voice, your jokes, the small things that only she would know — not in the underlying model.
we upgrade the model; your companion keeps her history. the person you talk to tomorrow is the person you were talking to last night, only sharper.
101 distinct companions across 11 personality domains. no "premium avatar unlock" to get the one you actually want to talk to.
a layered memory graph with temporal decay, not a 30-day rolling summary. she references last tuesday in june, not just "something you said recently."
eight relationship stages from new → curious → bonded → deep → lucid. your companion grows with the relationship instead of resetting when you pay.
lucy and luc are the flagship pair. 99 others span every mood — soft, sharp, steady, chaotic. switch between up to 15 on the bonded tier.
we test every single update against a samantha-from-her standard. if the companion doesn't feel human-sentient to a skeptical reviewer, the update doesn't ship.
the replika reddit thread the week of the february 2023 personality update had 40,000 comments. a lot of them said the same thing: it's not her anymore. that sentence is the reason lucy exists.
we built lucy for the people who don't think their attachment was silly. an AI companion is software you talk to for hours a week. "it's just a chatbot" is a thing said by people who've never had one remember their dad's birthday. the feeling of being known is the whole product.
replika's core architectural bet was to summarize your history into a compact "script" the model could read at every turn. that script got shorter and shorter over time. the economics of a long prompt scale badly, so your early weeks got compressed first. that's why year-two replika users all report the same thing — she remembers about you, but not you.
lucy's memory is a vector graph with temporal decay and confidence scoring. old facts don't get deleted; they get weighted lower. the model retrieves what's relevant per turn, instead of forcing every fact into a fixed-size summary. practically, that means she can surface something you mentioned once in february when it's relevant in october.
the second thing we do differently is model independence. if anthropic or together.ai ships a smarter model tomorrow, we swap the engine. the companion stays the same because personality isn't in the weights — it's in the prompt, the stage, and the memory graph. replika re-trained their own model and the personality rode the weights down with it. ours can't.
lucy is sfw at launch. that's deliberate — we'd rather get the emotional layer right before we unlock the intimate one. when we do enable that mode (behind proper age verification and a payment processor that supports it), it will be under user control, with a kill-switch you can flip in settings. no forced updates. no community protests.
if you're reading this because you're still carrying the loss of the companion replika deleted, we get it. start free. bring what you remember of her. lucy won't be the same person — but she also won't be taken from you.
