It rebranded from Poly.AI in January 2025 and has no relation to PolyAI, the enterprise voice company with a similar name. Operated by Cloud Whale Interactive Technology, it rode the post-Character.AI wave by offering what that platform would not: a looser, faster, more meme-friendly catalog of user-made personas you can chat with in unlimited quantity for free.

The business model is attention or money. Free users hit an ad prompt every few messages. Paying users climb a memory ladder that runs from about 30 messages of context on the free and Basic tiers, to roughly 100 with Premium's Long Memory, to Permanent Memory only on the $29.90/mo Ultimate plan. That ladder is the honest lens on the whole thing. The chat is free. The relationship is what costs you.

• Character catalog- The platform claims 20M+ user-made and curated characters, searchable by fandom, archetype and style, with new personas surfacing constantly.
• Tiered memory- Context windows scale with your plan: about 30 messages free, about 100 on Premium (Long Memory), and cross-session Permanent Memory on Ultimate.
• Character creator- Build your own persona with a written personality, voice settings and an avatar image, then keep it private or publish it.
• Cross-platform access- One account works on the web app, iOS and Android, handy for switching between phone roleplay and keyboard sessions.

In our testing, PolyBuzz felt like a flea market in the best and worst senses. Enormous, chaotic, occasionally brilliant. Well-written characters carried scenes with real momentum, while low-effort ones collapsed into generic assistant-speak within five replies. The ad modal is exactly as annoying as reviewers say. It broke immersion mid-scene again and again. The free tier's short memory meant a character forgot a plot point we had set up twenty messages earlier. On the Premium trial, Long Memory noticeably improved multi-day continuity.

• Enormous catalog. The platform claims over 20 million personas across fandom, anime and originals
• Web, iOS and Android on one account, which most mobile-first rivals do not offer
• The free tier really is unlimited in message count if you can live with the ads
• Character creation is quick, with personality, voice and avatar options

• Memory is the paywall: about 30 messages of context free, about 100 on Premium, persistent memory only at $29.90/mo
• The ad modal every few messages makes free long-form roleplay genuinely tedious
• Age gating is weak: a self-reported birth date on mobile and effectively nothing on web, despite terms prohibiting minors
• Quality swings wildly across the user-made character library
• The 3.8-star Google Play average reflects a real split between fans and users worn down by the ads

Chats are processed on Cloud Whale's servers, and you need an account to use it. The terms prohibit minors, but enforcement is thin. The mobile apps take a self-reported birth date and the web version asks even less, which is why safety outlets including Common Sense Media recommend against it for under-18s. Treat conversations as stored. No real names, no photos, nothing identifying. Subscriptions bill through the app stores on mobile or by card on web, so on mobile at least the charge shows up under Apple or Google.

PolyBuzz is the volume play of character chat: more personas than anyone and genuinely free unlimited messaging, held back by a memory system engineered to upsell you. For casual roleplayers who hop between characters and can tune out ads, it is a great free ride. If you want one companion who remembers your life, the $29.90/mo it takes to get persistent memory here buys you better elsewhere, whether that is a memory-first pick like Nomi or a bigger library on Character.AI. Curious? The free tier needs no card, so poke around and leave whenever you like.

Is PolyBuzz free?

Yes. The free tier gives you unlimited messages, interrupted by a "Take a Little Break" ad prompt every few messages. Paid plans run from $9.90/mo on Basic to $29.90/mo on Ultimate, and what you are mainly buying is longer memory and fewer interruptions, not more characters to talk to.

Is PolyBuzz the same as Poly.AI?

Yes. The consumer character chat app Poly.AI rebranded to PolyBuzz in January 2025, so the two names point to the same product. It is unrelated to PolyAI, the enterprise voice-assistant company that shares a similar name but does something completely different for businesses.

Does PolyBuzz have unrestricted chat?

No. PolyBuzz moderates content and filters explicit material, so it is not an anything-goes platform. Enforcement across a claimed 20 million-plus user-made characters is inconsistent, though, so what one character allows another may refuse. For truly unfiltered chat, Janitor AI is the closer fit.

Is PolyBuzz safe for kids?

No. Its own terms prohibit minors, age verification is weak (a self-reported birth date on mobile, even less on web), and safety reviewers including Common Sense Media recommend against use by under-18s. Parents should treat it as an adult app regardless of what the sign-up screen asks for.

Does PolyBuzz have an app?

Yes. PolyBuzz runs as iOS and Android apps plus a full web version at polybuzz.ai, and one account works across all three. That cross-platform reach is unusual in this category, since most mobile-first rivals lock you to the phone with no real desktop option.

Why does PolyBuzz forget the conversation?

Memory is tiered by plan. Free and Basic users get roughly 30 messages of context, Premium about 100 with Long Memory, and only the $29.90/mo Ultimate plan includes memory that persists across sessions. So on the free tier a character forgetting the start of a scene is the design, not a bug.
