Take the Reins of your AI. Reins connects to your Ollama, LM Studio or any OpenAI-compatible server and brings powerful AI models like Llama, Gemma, Qwen and more to your iPhone and iPad — with tools, web search, and full control over every conversation. No login. No data collection. PRIVATE BY DESIGN No login. No account. No data collection. Every chat stays yours. TOOLS & WEB SEARCH Go beyond chat. Reins gives models the ability to search the web, fetch pages, calculate and reason across multiple steps — no API key required for web search. FULL MODEL CONTROL Download, switch and manage your models directly from the app. Connect multiple servers, configure API keys and custom headers and switch between them instantly. Access Ollama Cloud when you need it. POWERFUL CHAT Attach images, PDFs, CSVs and text files to any conversation. Enable thinking mode for deeper reasoning when you need it. Branch chats to explore different paths without losing your original thread. Never lose a cut-off response, pick up exactly where it stopped. Export or back up your conversations anytime. FINE-GRAINED CONTROL Set a different system prompt for every conversation. Dial in temperature, context size, max tokens and more for precise control over model behavior. BACKGROUND PROCESSING No need to wait around for complex reasoning or long responses. Switch apps or lock your screen and Reins keeps generating in the background. Come back and it'll be waiting for you. (Requires iOS or iPadOS 26.0+) Reins requires an Ollama, LM Studio or OpenAI-compatible server. Self-hosted or Ollama Cloud both work.
