What both publish
| Fact | Chub AI | HammerAI |
|---|---|---|
| Documentation depth | The official guide covers onboarding, character creation, chatting, prompting, API connections, lorebooks and stages, with Markdown pages and an index. | Official docs cover installation, Ollama, Linux, vision models, characters, chat, lorebooks, personas, stories, image generation, quantization, proxy models and model parameters. |
| Image generation | Image generation is listed as a supported Chub feature. | Image generation works inside chats and as standalone images with prompt, seed and aspect-ratio controls; local image generation is planned rather than available. |
| Local models | Kobold/Ooba connections can use models hosted on a user's own machine, subject to local hardware limits. | The desktop app runs large language models locally through Ollama, keeping processing on the user's computer. |
| Lorebooks | Lorebooks inject user-written context when keywords appear, adding conditional world information to prompts. | Lorebooks provide dynamic memory for world facts and story context. |
| Praise: roleplay quality | Independent reviewers repeatedly praise immersive, high-quality responses and characters that usually stay in role. | DreamGen reviewers reported strong character consistency, dynamic prose, useful model controls and good image results. |
| Privacy promise | An independent security summary quoting Chub's policy says private characters and chats are not distributed to third parties or used to train AI models. | HammerAI says it does not use conversations, characters or stories to train its own AI models. |
| Product | Chub is a platform for interacting with characters through AI large language models accessed through APIs. | HammerAI describes itself as an AI character chat and roleplay platform. |
| Rating on Apple App Store | 4.3 out of 5 from 79 ratings (archived listing data). | 3.2 out of 5 from 17 ratings |
| Support | The support page says users with questions or problems can contact [email protected]. | Users can submit feedback in-app or contact HammerAI through Discord, Twitter, Reddit, and TikTok. |
