Best AI Chatbot Software

PolyBuzz is an AI chatbot and roleplay platform where users converse with AI-generated characters or build their own. The platform gives access to a library it describes as more than 20 million characters, spanning anime, manga, movie and celebrity personas, and genre-based roleplay scenarios such as fantasy, horror, and romance tropes like enemies-to-lovers or fake dating. Users can build custom characters by setting a name, personality, backstory, appearance, and voice, and can import character concepts created on other platforms. Conversations run primarily as text chat, and paid tiers add AI-generated voice responses using text-to-speech, plus a Live Photos feature that generates a still image reflecting a moment from the conversation. Custom AI image generation and webtoon-style content tools are also available.

PolyBuzz is free to start, with unlimited text chats on a standard AI model, though the free tier shows periodic ads and keeps a shorter conversation memory. Paid membership tiers, priced roughly between $9.90 and $29.90 a month, remove ads and add stronger AI models, longer memory, extended voice chat, faster responses, and more image-generation attempts; the platform also sells optional coin bundles for extending voice calls or unlocking specific interactions. PolyBuzz states that conversations are confidential and not accessible to character creators or its own staff unless a user chooses to share them, and it runs a dedicated Teen Mode alongside AI and human moderation to restrict public NSFW content. It's available through a web browser or iOS and Android apps, aimed at roleplay fans, anime followers, and creative writers seeking a customizable AI companion.

Millions of user-created characters are available on the platform, ranging from original creations to characters based on fictional stories, historical figures, and other public personas. Conversations happen primarily through text, with users able to rate responses to help refine how a character behaves over time. The platform also supports Rooms, where multiple characters and users can interact together in a shared conversation.

Beyond text chat, Character.AI offers Character Calls, a voice conversation feature built on more than a million community-created voices and available in numerous languages, and Scenes, which places users into structured, guided roleplay scenarios with preset environments. A free plan provides access to core chat features, while the c.ai+ subscription, priced at $9.99 per month or a discounted annual rate, adds priority access during busy periods, faster response times, expanded memory, unlimited voice calls, and an ad-free experience.
