Tambourine

Tambourine provides an open‑source platform for AI‑powered voice dictation that can be used with any text‑input application on Windows or macOS. Users select their own speech‑to‑text and language‑model back‑ends, including cloud services or locally run Whisper and Ollama, and then define prompts that control formatting, punctuation, and tone. The system includes built‑in features such as a personal dictionary for domain‑specific terminology, backtrack corrections that let speakers amend mistakes on the fly, and automatic list formatting.

The software is aimed at developers and power users who want a customizable voice interface rather than a fixed dictation tool. Because the core logic resides in editable prompts, users can extend or replace functionality, adding features like context‑aware dictation, app‑specific formatting, selection commands, or voice‑triggered shortcuts. All components are released under an open‑source license and can be self‑hosted or run via a hosted service, with a free tier available for experimentation.
