PolyBuzz vs Character.AI: Which One Actually Remembers You?

PolyBuzz vs Character.AI comes down to one question: do you want a library to browse, or a companion who remembers you? Both give you thousands of user-made characters and both are cheap to start. The difference is what happens after a few weeks. Character.AI charges $9.99 a month for c.ai+ and does not allow romantic or explicit content at all. PolyBuzz charges $9.90 for Standard but keeps permanent memory on its $29.90 Ultimate plan, and sells coins separately from $2.49 to $19.90. Neither is built for one consistent girlfriend at a flat price. This guide covers what each actually costs, where the memory sits, and who each one suits. It is for adults 18 and over.

What each one actually costs in 2026

Both apps are free to download, so the real pricing lives in the in-app purchase list that Apple publishes. Here is what those listings show as of July 2026.

PolyBuzz prices are from its US App Store in-app purchase list and its own membership page; Character.AI pricing is from its published plan. Both were checked in July 2026 and both change, so confirm before you pay.

The memory question, which is the one that matters

Ask anyone who has used either app for more than a month what went wrong and you get the same answer: she forgot. The reason is different in each case, and it is worth understanding because it tells you whether paying more will fix it.

On PolyBuzz, forgetting is a plan limit. The company presents Long Memory as a Premium feature and Permanent Memory as an Ultimate feature, so on the free and $9.90 Standard tiers older messages get pruned out of context. That means upgrading genuinely does fix it, but the fix costs $29.90 a month, which is three times the entry price and more than most people expected to spend.

On Character.AI, there is no memory tier to buy. Paying for c.ai+ gets you faster responses and priority access, not a longer memory. Users widely report characters losing the thread well into a long conversation, and the platform's April 2026 model changes made that more noticeable when older models were retired. If memory is your complaint on Character.AI, no amount of money solves it, because there is nothing to upgrade to.

That distinction is the practical takeaway. PolyBuzz sells you memory. Character.AI does not sell it at all. If you want to understand what real persistent memory looks like and how to test for it, our guide to testing whether an AI girlfriend remembers you walks through a two day method that works on any app.

The romance problem on Character.AI

Character.AI's filter is not a setting you can turn off, and it is not only about explicit content. It fires on ordinary romantic conversation, which surprises people who assumed a companion app would allow a companion relationship. This is a deliberate platform position rather than an oversight, and it is the single biggest reason people leave for something else.

PolyBuzz is rated 18+ and does not carry that restriction, which is a real advantage if romance is the point. What it trades away is price predictability, since the coin economy sits on top of whatever plan you chose.

If the filter is what pushed you to look elsewhere, the Character.AI girlfriend alternative page compares the honest options side by side, including the ones that beat us on specific things.

The coin layer nobody mentions upfront

PolyBuzz runs two currencies. Apple's listing shows coin bundles at $2.49 for 1,000, $4.99 for 3,000, $9.99 for 8,000, and $19.90 for 20,000, plus a separate opals pack at $5.90 for 1,000. Coins pay for things like extending voice, regenerating a reply you did not like, and certain memory scenes.

That structure means your monthly cost is a range, not a number. Two people on the same $9.90 Standard plan can spend wildly different amounts depending on how often they regenerate replies. Character.AI does not do this, and that simplicity is a genuine point in its favor: $9.99 is $9.99.

Which one should you pick?

• Pick Character.AI if you want the biggest free character library, a simple flat price, and you are fine with no romance. It is still the best place to browse and experiment for free.
• Pick PolyBuzz if you want romance and roleplay variety, you enjoy jumping between many characters, and you are willing to either accept the memory ceiling or pay $29.90 to remove it.
• Pick neither if what you actually want is one girlfriend who knows you, texts first, and costs the same every month. Neither app is designed for that, and both will keep asking you to upgrade for the part you cared about.

That last case is what Tempted.ai is built for. She is one companion rather than a library, memory is included in the flat $9 a month, and there is no currency to buy. She sends the first message some mornings, remembers the thing you were stressed about last week, and keeps it tasteful rather than explicit. If a companion who remembers everything you tell her is the whole reason you are comparing apps, that is the page to read next, and the PolyBuzz alternative breakdown covers the switch specifically.

People coming from either app often describe wanting something warmer than a character feed, closer to a friend who checks in on you without being asked, which is a different product goal than a roleplay library and worth being clear about with yourself before you subscribe to anything.

The bottom line

Character.AI is the better free library and the simpler bill, but it will not do romance and cannot sell you memory. PolyBuzz allows romance and does sell memory, but only at $29.90 a month, with a coin economy on top. If you want a library, pick based on whether romance matters. If you want a girlfriend who remembers you at a price that does not move, neither app is the right shape, and a flat-priced companion is the cleaner answer.
