Reins
An open-source Ollama chat client runs on mobile and desktop, with separate model settings for each conversation and support for images.

Reins is a chat app for people using self-hosted LLMs through Ollama. It gives you a mobile and desktop interface for comparing models and keeping different instructions for different conversations.
- Settings per conversation: Give each chat its own system prompt, model and response settings, including randomness and context size.
- Model switching: Change models within an existing conversation to try another model against the same discussion.
- Editing and regeneration: Revise messages and generate responses again to explore how a changed prompt affects the result.
- Reusable prompts: Save system and chat prompts as new models for reuse in other conversations.
- Images and streaming: Send and receive images in chats, and read responses as they arrive.
Reins runs on iOS, Android, macOS, Linux and Windows. It's an open-source client under GPL-3.0; Ollama supplies the model backend.
