OpenTypeless is a free, open-source desktop voice typing application that works across Windows, macOS, and Linux. It transcribes speech in real time using your choice of speech-to-text providers such as Deepgram, OpenAI Whisper, or AssemblyAI, with support for 99 languages. An optional AI polishing layer can refine grammar, remove filler words, and adapt formatting based on the active app, with 71 built-in app profiles covering email, chat, documents, and code. Users bring their own API keys for both STT and LLM providers, ensuring no vendor lock-in, and a local processing route via Whisper-compatible endpoints and Ollama is also supported.
