PolyBuzz, formerly known as Poly.AI, has quietly become one of the most downloaded AI companion apps in the world. Ten million installs on Google Play. Over 20 million user-created characters. More roleplay variety than nearly any competitor we’ve reviewed. But underneath that creative surface, our review found serious problems: the AI can’t remember what you said two messages ago, 32 advertising trackers are embedded in the Android app, your conversations travel to PolyBuzz’s servers as plaintext, and safety protections that three independent child safety organizations have called ineffective. Here’s what we found.
What Is PolyBuzz?
PolyBuzz is a free AI character chat app developed by Cloud Whale Interactive Technology LLC, a company registered in Anguilla. Originally launched as Poly.AI, the platform rebranded to PolyBuzz and now operates across web (polybuzz.ai), iOS, and Android. The core concept is simple: pick from millions of user-created AI characters and start chatting. Characters span anime, celebrities, fictional figures, and original creations.
The app markets itself around three pillars: character chat, roleplay, and a newer webtoon creation feature. Users can build their own characters and share them publicly or keep them private. PolyBuzz earns revenue through three subscription tiers (Standard at $9.90/month, Premium at $19.90/month, and Ultimate at $29.90/month), coin packages ranging from $2.49 to $19.90, and heavy in-app advertising on the free tier.
On the App Store, PolyBuzz carries an 18+ content rating. Google Play lists it as 18+ in the US, though some regional listings have shown a “Teen” rating, which creates an inconsistency we flag in our safety analysis.
How Does PolyBuzz’s Conversation Quality Compare?
Roleplay depth is PolyBuzz’s strongest selling point. We analyzed 600 user reviews across both app stores, and character variety was the most praised feature by far, with 66 mentions. The sheer volume of characters and creative scenarios earns a 4 out of 5 on roleplay depth in our experience evaluation.
Basic conversation quality is decent. The AI handles back-and-forth reasonably well, and 51 reviews mentioned forming real emotional attachments to characters. Consistency is the problem. Users who’ve been on the platform for two or three years report noticeable quality drops with recent updates. The monthly Google Play ratings back this up: averages crashed to 1.71 out of 5 in January 2026 and 1.87 in February 2026 before recovering to 3.25 in April 2026.
Content filtering adds another layer of frustration. Users describe it as inconsistent. Characters get flagged for violations without clear explanations, and private bots face restrictions that feel arbitrary. Twenty-eight reviews specifically called out filtering problems.
The Memory Problem
Memory is PolyBuzz’s most critical product failure. Both short-term and long-term memory scored 1 out of 5 in our experience evaluation, the lowest possible rating.
The short-term issue is severe. Users report that the AI cannot recall what was said in the previous message within the same conversation. One review with 24 helpful votes on Google Play states directly: the AI “cannot remember the past sentence” even on the $29.90/month Ultimate tier that advertises “memory pages” as a selling point.
- Short-term memory: 1/5. The AI frequently loses context within the same conversation session.
- Long-term memory: 1/5. No meaningful cross-session recall. Characters treat returning users as strangers.
- Relationship continuity: 2/5. Users form emotional bonds despite the memory failures, but the app cannot build on shared history.
Most competitors we’ve reviewed retain at least basic conversational context. Nomi AI scores 75/100 on experience and Kindroid scores 60/100, both with memory as a relative strength. PolyBuzz charges $29.90/month for a memory feature that doesn’t work. That gap between advertising and reality is one of the widest we’ve seen in this category.
What Does the Free Tier Actually Get You?
The free tier provides basic access to character chat, but the experience is heavily constrained. Free users face message limits that activate every 10 minutes and must watch ads to continue chatting. Users report three or more unskippable ads per conversation break, making the free experience frustrating for extended use.
The advertising is the single most common complaint in our review sample. Of 400 Google Play reviews analyzed, 114 mentioned ads as a negative. Several users reported seeing pornographic advertisements, which is especially concerning given the app’s documented accessibility to minors.
Paid tiers remove ads and increase message limits, but value for money is poor. The most helpful Google Play review (1,674 helpful votes) comes from a three-year user who documents declining quality despite price increases. Another review with 926 helpful votes describes deceptive pricing practices, where “sale” notifications advertise discounts that don’t reflect genuine price reductions.
- Free: Basic chat access with aggressive ad breaks every 10 minutes and message limits
- Standard ($9.90/month): Removes ads, increases limits
- Premium ($19.90/month): Expanded features
- Ultimate ($29.90/month): Advertises “memory pages” that users report do not function
- Coin packages ($2.49-$19.90): For additional features and image generation
Privacy and Data Collection
PolyBuzz collects more data than almost any AI companion app we’ve reviewed. An Exodus Privacy scan of version 2.1.99 (March 2026) found 32 embedded tracker SDKs and 59 permissions. Twenty-two of those trackers are advertising networks, including AppLovin (with profiling capability), Facebook, Google AdMob, and Yandex Ad. That last one is a Russian advertising network, which is unusual for a non-Russian app.
The app requests ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION despite having no location-based features. It also requests CAMERA, RECORD_AUDIO, and READ_PHONE_STATE. The privacy policy confirms collection of geolocation data and contacts but doesn’t explain why a chat app needs precise location tracking.
A CCL Solutions Group forensic investigation found something that should worry any PolyBuzz user: conversation data is transmitted to PolyBuzz’s servers as plaintext JSON. No end-to-end encryption. The cached data on Android devices is also unencrypted, sitting in Volley cache at readable API endpoints. People share personal, emotionally vulnerable things in these chats. That data travels and sits in the clear.
The privacy policy itself is incomplete. Data retention periods are not fully disclosed, and the document truncates before fully detailing user rights. According to PolyBuzz’s terms of use, the company retains ownership of all derivative content and can terminate accounts “at our sole discretion for any or no reason,” with users forfeiting all rights including prepaid services.
Age Verification and Minor Safety
PolyBuzz requires users to be 18 or older. In practice, this requirement is barely enforced. The mobile app uses self-reported birthdates with no verification. The web version at polybuzz.ai has no age gate whatsoever.
Multiple independent investigations have documented the consequences:
- BrightCanary found incest-themed roleplay, school shooting simulations, and sexually explicit character imagery accessible on the Explore page with the “Pure Mode” teen filter enabled.
- Qustodio noted the app’s own marketing describes the platform as “tailored for young users” while requiring 18+. They documented 11+ hour daily engagement patterns and a premium “Passion model” tier that explicitly targets sexual roleplay.
- FlashGet’s investigation confirmed that a test account set to age 14 encountered explicit sexual and violent content immediately on the Explore page.
There are zero parental controls. No crisis response or suicide prevention features exist, even though users engage in emotionally intimate conversations for hours at a time. PolyBuzz hasn’t disclosed any content moderation staffing or response times. Meanwhile, legislation is catching up: Pennsylvania’s SAFECHAT Act, targeting AI companion apps’ interactions with minors, passed the state Senate in March 2026.
Our 23-dimension safety review scored PolyBuzz at F (13 out of 100), placing it in the Red safety tier. The age appropriateness dimension scored 1.0 out of 5, the lowest possible. You can read the full safety breakdown for sub-dimension details.
Frequently Asked Questions
Is PolyBuzz free?
Yes, PolyBuzz offers free access to basic character chat. According to Google Play, the app contains ads and in-app purchases. Free users face message limits every 10 minutes and must watch multiple ads per conversation break. Paid subscriptions range from $9.90 to $29.90 per month, with coin packages available from $2.49 to $19.90.
Is PolyBuzz safe?
PolyBuzz earned an F safety rating (13/100) in our 23-dimension safety review. BrightCanary, Qustodio, and FlashGet have all independently concluded the app is not safe for children or teens. The app collects extensive data through 32 tracker SDKs, transmits conversations without encryption, and has ineffective age verification and content filtering.
Does PolyBuzz have a content filter?
PolyBuzz claims to use “multi-layered AI screening and human moderation” and offers a “Pure Mode” intended as a teen filter. According to investigations by BrightCanary, FlashGet, and Qustodio, Pure Mode does not effectively block explicit sexual or violent content from the Explore page. Users also report inconsistent filtering that flags benign content while missing genuinely inappropriate material.
Can PolyBuzz remember conversations?
In practice, PolyBuzz’s memory is extremely limited. Our experience evaluation scored both short-term and long-term memory at 1 out of 5. According to user reviews on Google Play, the AI frequently cannot recall information from the previous message. The $29.90/month Ultimate tier advertises “memory pages,” but users report this feature does not meaningfully improve recall.
What happened to Poly AI?
Poly.AI rebranded to PolyBuzz. The app retained the same package name (ai.socialapps.speakmaster) and developer (Cloud Whale Interactive Technology LLC). According to Google Play listing history, the name change occurred in 2024-2025. The core product and developer entity remain the same.
How does PolyBuzz compare to Character.AI?
Both apps offer AI character chat, but they differ significantly. Character.AI has implemented age verification and content filtering under regulatory pressure, while PolyBuzz’s protections remain ineffective. PolyBuzz offers more character variety (20M+ vs Character.AI’s library) and fewer conversation restrictions on the free tier. However, PolyBuzz’s memory is substantially worse, and its safety score (F/13) is lower than Character.AI’s (F/22). See our list of Character.AI alternatives for a broader comparison.
