mercuryScribe vs Speechmatics

mercuryScribe is a locally run web interface for transcribing audio and video, with transcript editing and document export. It uses Faster Whisper for speech transcription and pyannote models to distinguish speakers. Users can edit transcripts in a browser, save changes as VTT files, and generate HTML or DOCX files containing speaker names and timestamps. The FAQ says audio, transcripts, and metadata are not sent to external services; the models are obtained from Hugging Face. Users need a Hugging Face access token and must accept terms for the required models. MAXQDA support is included by default, and custom integrations can be developed. The maker documents Docker, Windows package, and Python package installation options. The software is free and open source under the MIT license for personal, academic, or commercial use, and is listed for Linux, macOS, Windows, and web. The maker describes it as built for researchers and also suitable for journalists, podcasters, organizations, educators, accessibility groups, and professionals. Professional services include installation help, training, workshops, and private server setup with GPUs.
