Say, Pi
Voice control for ChatGPT, Pi and Claude AI assistants

About Say, Pi
Say, Pi is a voice layer for popular AI assistants, aimed at people who would rather talk than type, including multitaskers and language learners. It adds voice to ChatGPT, Pi AI and Claude AI, so conversations can run hands-free in more than 30 languages.
Its Agentic Listening feature decides when to listen and when to reply, which keeps back-and-forth conversations smooth and free of interruptions. Users can switch between hands-free, agentic and manual response modes at any time. Transcription is powered by OpenAI's Whisper model, and the site describes its speech synthesis as high quality across languages.
Say, Pi also includes Universal Dictation, which lets people dictate into any text field on any website by clicking the Say, Pi icon. It is positioned as a desktop-first tool, with a free-to-try web listing and a pricing page for paid plans.
