What is RunAnywhere?

RunAnywhere lets you add AI features to your mobile app that run entirely on-device:

• LLM Chat — Llama, Mistral, Qwen, SmolLM, and more
• Speech-to-Text — Whisper-powered transcription
• Text-to-Speech — Neural voice synthesis
• Voice Assistant — Full STT → LLM → TTS pipeline

No cloud. No latency. No data leaves the device.
