## CHAI

CHAI is one of the earliest consumer AI chat platforms, launching on the App Store ahead of Character.AI and ChatGPT. Users create their own AI characters and stories, then chat with them across iOS, Android and the web. The company reports more than 10 million active users and an annualised revenue run-rate above $120 million, making it one of the largest independent consumer AI apps by usage.

Rather than relying on third-party foundation models, CHAI trains its own LLMs in-house and continuously optimises them specifically for social and entertaining conversation using reinforcement learning from human feedback. The engineering blog details a progression from a 6B model through 13B and 24B blends to Mixture-of-Experts architectures, plus techniques such as model blending, best-of-N rejection sampling, PPO, DPO and GRPO that measurably improved retention and session length.

That research focus extends to infrastructure. CHAI runs a multi-vendor GPU fleet of AMD and NVIDIA accelerators exceeding 1.4 exaflops for inference, serving hundreds of in-house models through a custom cluster orchestrator. The site is primarily the company and research presence — product usage happens in the mobile and web apps — and includes documentation of the training roadmap, safety practices, funding and careers.

**Pricing & Plans:** Freemium consumer app with optional in-app subscription for additional features and faster responses; the corporate site itself is informational rather than a storefront.

- **Create your own AI characters:** Build custom ChatAI characters with their own personalities and backstories, then chat with them or browse characters created by other users.
- **In-house LLMs tuned for conversation:** CHAI trains and serves its own language models rather than reselling third-party APIs, optimising them specifically for engaging, social dialogue.
- **Reinforcement learning from user signals:** Reward models trained on large volumes of user feedback, combined with PPO, DPO and GRPO, iterate the models to increase retention and session length.
- **Large-scale custom inference:** A multi-vendor AMD and NVIDIA GPU cluster exceeds 1.4 exaflops, with a custom orchestrator serving hundreds of models in production.
- **Cross-platform access:** Use CHAI on iOS and Android with a web version available, so conversations carry across devices.

**Strengths:** Purpose-built consumer app with a large, active user base and polished mobile experience; In-house models tuned for engagement deliver more natural, personality-rich conversation than generic chatbots; Free to use at the core, with paid options only if you want extras; Transparent published research on training techniques, cluster scale and safety

**Limitations:** Optimised for entertainment and engagement, so it is not a reliable tool for factual research or work tasks; No public developer API or enterprise automation offering comparable to business AI platforms; Moderation and safety constraints can limit certain roleplay scenarios

## PolyBuzz

Originally launched in 2023 as Poly.AI and rebranded to PolyBuzz in January 2025, this platform operated by Cloud Whale Interactive Technology LLC has grown into one of the highest-traffic character chat networks in the world, accumulating over 1.18 million ratings on Google Play. Its core attraction is sheer variety and low-friction entry: users can browse more than 20 million community-built characters spanning anime, K-pop idols, dark romance, mafia tropes, BL/GL manhwa, and tabletop RPGs, and start chatting immediately on the web or Android without hitting a daily message wall.

While basic text chat and standard voice listening are free, PolyBuzz monetizes aggressively through a dual system of recurring memberships and two separate microtransaction wallets (Coins and Opals). Free users interact with a baseline model supported by frequent video and banner ads. Upgrading to Poly Standard ($9.90/month), Poly Premium ($19.90/month), or Poly Ultimate ($29.90/month) removes ads, unlocks unlimited character voice playback, and grants access to specialized narrative models such as Tale, Passion, and Ultimate's Permanent Memory Model. However, high-end modes and interactive extras frequently tap into secondary currencies: Coins ($2.49 for 1,000 up to $19.90 for 20,000) pay for response regenerations, inspiration reply suggestions, Conqueror rounds, and generated Memory Scenes, while Opals ($5.90 for 1,000) meter elite Sovereign mode conversations.

In 2026, PolyBuzz expanded its web portal (polybuzz.ai) into a broader entertainment hub with built-in AI image generation, AI webtoon feeds, and cross-promotion with ReelFever short dramas. Following tighter moderation updates and a June/October 2026 Terms of Use revision that strictly prohibits users under 18, PolyBuzz heavily filters public character imagery while keeping one-on-one chat transcripts private from bot creators. Notably, after its iOS app was removed from the Apple App Store on October 15, 2026, iPhone users primarily access the service via the mobile web portal while Android and desktop web apps remain active.

**Pricing & Plans:** Provides a generous ad-supported Free tier with unlimited basic text chat across 20M+ characters, alongside tiered memberships: Poly Standard ($9.90/mo), Poly Premium ($19.90/mo or $9.99/wk), and Poly Ultimate ($29.90/mo featuring permanent memory models). It also uses two virtual currencies on top of subscriptions: Coins ($2.49 for 1,000 up to $19.90 for 20,000) for regenerations, voice extensions, and memory scenes, plus Opals ($5.90 for 1,000) for Sovereign mode.

- **20M+ Community Character Library:** Hosts an expansive, tag-searchable directory of over 20 million user-created bots across anime, gaming, celebrity, dark romance, enemies-to-lovers, and original fiction tropes.
- **Tiered Narrative Modes (Tale, Passion, Conqueror & Sovereign):** Offers distinct AI generation engines tailored for descriptive storytelling (Tale), romantic intensity (Passion), Permanent Memory (Ultimate), and high-context Sovereign and Conqueror rounds.
- **Character Voice Playback & Animated Live Photos:** Pairs text replies with synthesized character voices and dynamic animated avatar backgrounds that shift expression with the mood of the scene.
- **Memory Scenes, Inspiration Replies & Web Image Studio:** Lets users spend Coins to generate illustrated Memory Scenes of pivotal roleplay moments, request AI-suggested inspiration responses when stuck, or create standalone character art on the web.
- **Cross-Platform Character Migration & Creation Guides:** Provides GitBook documentation and character import workflows so creators can migrate bots from other platforms and customize greetings, dialogue style, and avatar mixes.

**Strengths:** Massive catalog of over 20 million user-made characters with genuinely unlimited free basic messaging; Built-in character voice audio and dynamic animated character backgrounds enhance mobile immersion; Specialized narrative modes (Tale, Passion, Sovereign) let paying users tune prose style and emotional tone; Private chat architecture ensures bot creators cannot read or access users' personal roleplay logs

**Limitations:** Complex, overlapping monetization combines $9.90–$29.90/mo subscriptions with separate Coin and Opal microtransactions; Free tier is interrupted by frequent ads and runs on a noticeably more repetitive base model with short memory; iOS native app was removed from the Apple App Store in October 2026, requiring iPhone users to rely on the web app
