Whisper Web Text-to-Speech
Browser-based speech transcription that keeps audio private and local
🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for Whisper Web Text-to-Speech, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology — every score is re-derived by the same automated method as an agent's public evidence changes.
Overview
Whisper Web is an in-browser speech-to-text application that transcribes audio files entirely on the user's device without uploading data to external servers. It leverages modern web technologies to run OpenAI's Whisper model locally, ensuring complete privacy for sensitive audio content. The tool is designed for individuals and professionals who need accurate transcription but are concerned about data security, confidentiality, or internet bandwidth. It solves the problem of trusting third-party cloud services with private recordings, meeting notes, interviews, or personal memos. Users simply open the web app, select an audio file, and receive a transcript—all processing happens within their browser.
