Yourai — free personal AI assistants, on your device

Create free AI assistants that run on your phone. Chat privately with local models, teach and traning them to be smarter, and keep control of your data.

WHY YOURAI
• On-device AI — models run locally on your phone when possible
• Your assistants — name them, set prompts, tune personality
• Privacy-first — chats and keys stay on your device
• Works offline — chat and reasoning without the cloud (with a downloaded model)
• Optional tools — Thinking, Web Search, and Deep Search when you need them

CREATE YOUR OWN ASSISTANTS
Build assistants for coding, language learning, writing, studying, or everyday help. Choose a base model, set a system prompt, adjust creativity and humor, and enable memory so your assistant remembers what matters.

CHAT THAT FITS HOW YOU WORK
• Markdown replies you can read and copy
• Attach photos, files, camera captures, and video (when the model supports it)
• Vision / OCR for image understanding on supported models
• Chat history and multiple conversations per assistant
• Online, offline-only, or prefer-offline modes

THINKING, WEB SEARCH & DEEP SEARCH
Turn on tools when you need them:
• Thinking — step-by-step reasoning on your device
• Web Search — look up fresh public information
• Deep Search — broader research across sources
Optional: add your own Brave Search or SerpApi key (stored on device) for better search results. Without a key, Yourai can still use free public sources.

TEACH & TRAIN
Improve assistants over time:
• Add your own examples, rules, and documents
• Benchmark skills (programming, English, math, science, and more)
• Use an optional improvement pipeline with your own API key (OpenAI, Anthropic, Gemini, DeepSeek, xAI, or custom)
• Keep training data local — Yourai does not store your authoring keys on its servers

COMMUNITY ASSISTANTS
Browse community packages, discover assistants by category, and fork ideas into your own library.

MEMORY & SYNC
Enable memory so assistants keep useful facts. Browse memory and sync when you choose — you’re in control.
