How Does Character Memory Work In Chub AI?

Chub AI uses context windows from your selected LLM to maintain conversation history. The platform's Lorebook system stores character backgrounds, world details, and user preferences. This allows the AI to reference past interactions and maintain narrative continuity across extended conversations without losing character consistency.

Can I Use My Own API Keys With Chub AI?

Yes. Both Mercury and Mars plans support direct API integration. You can connect your own OpenAI, Anthropic (Claude), or OpenRouter API keys to use your preferred language models. This gives you complete control over which AI model powers your character interactions and allows cost optimization based on your usage patterns.

What's The Difference Between Mercury And Mars Tiers?

Mercury ($5/mo) provides access to premium Soji models with higher daily message limits and priority queue access. Mars ($20/mo) unlocks maximum model availability and API throughput. Both support full customization and API integration. The choice depends on your frequency of use and desire for the highest-quality model access.

Is Chub AI Safe For User Data And Privacy?

Chub AI implements encryption for data protection and explicitly states they don't run ads or sell user data. The platform employs security measures to protect conversation history and character information. Users should review the official privacy policy at chub.ai/privacy for complete transparency on data handling and retention policies.

Can I Download Characters For Offline Use?

Yes. Chub AI allows character export in standard formats compatible with other platforms like SillyTavern. This flexibility lets you download character cards and use them offline with compatible UIs, providing portability and backup options independent of Chub's infrastructure.

What is Chub AI?

Chub AI is an uncensored roleplay and interactive storytelling platform that helps adults create and converse with customizable AI characters across long-form, often explicit narratives.

As of 2026 it’s aimed at writers, roleplayers, erotica authors and adult hobbyists who want persona-driven sessions rather than templated replies.

The interface exposes persona fields and backstory templates, per-character system prompts, editable memory snippets that persist across sessions, session versioning and exportable chat logs; users can also route chats through API keys to OpenAI, Anthropic or compatible LLM providers and adjust temperature, response length and model selection per conversation.

Notable capabilities include layered memory control (what the character remembers), per-character prompt overrides for tone and boundaries, and paid options that increase context windows and priority model access.

Chub AI runs a freemium model with advanced features behind subscription tiers; honest trade-offs are clear — minimal platform filtering places legal and privacy responsibility on users, output fidelity varies with the chosen model and higher-quality experiences often require paid model access.
