the subscription vs. credits dilemma for ai companions

when we started building lucy, the first big question wasn't about ai. it was about money. how do you charge for something people use in such wildly different ways.

some people talk to their ai companion every day. it's part of their morning coffee, their evening wind-down, their creative process. for them, a subscription makes perfect sense. it's predictable. they pay a flat fee, and they get unlimited access. no surprises.

but not everyone is like that. some people open the app once a week, or once a month. maybe they have a specific question, or they're feeling lonely on a tuesday night. for them, a subscription feels like a tax on existence. it's a monthly reminder of something they barely use.

why subscriptions dominate

you see subscriptions everywhere in tech because they're easy. easy to build, easy to manage, and they generate predictable revenue. that predictability is everything for a small team. it lets us plan, hire, and keep the servers running without constantly worrying if this month's revenue will cover next month's cloud bill.

but easy doesn't always mean right. a subscription-only model forces everyone into the same box. it assumes a level of usage that just isn't universal.

the case for credit packs

credit packs are messy. revenue becomes unpredictable. one month you sell a ton, the next month almost nothing. it's a nightmare for forecasting.

but they're incredibly user-friendly for casual visitors. you buy, say, 100 credits. you use them when you want. no clock ticking. no guilt about wasting a monthly fee. you only pay for what you consume.

the honest math

let's do some quick math. our subscription is $10/month. a casual user who sends maybe 20 messages a week would spend roughly $1-2 in credits for the same usage. they'd save about $8-9 a month by not subscribing.

for a daily user, the math flips. someone sending hundreds of messages a day would burn through credits fast. for them, the subscription is a massive discount. they'd save a lot of money.

the design decision: let people choose

the obvious solution was to offer both. we didn't want to force heavy users to nickel-and-dime themselves with credits. and we didn't want to force casual users into a subscription they'd resent.

so we built both systems. you can subscribe for unlimited access. or you can buy a pack of credits that never expire. you choose what fits your life.

it's more work for us. two payment systems to maintain. two revenue streams to track. but it feels honest. it respects the different relationships people have with technology.

the lucy limitation

there's one catch. the subscription is the only way to get some of the more advanced features that require constant, heavy server use. things like long-term memory, deep conversation analysis, and custom voice. those features are expensive for us to run, so they're locked behind the subscription tier. credits are for the core chat experience.

it's not a perfect system, but it's a human one. it starts from how people actually live, not from a spreadsheet.

maybe you're a daily user. maybe you're a sometimes-user. either way, there's a path for you.
