What is Questro | AI Interpreter?
Questro is a browser-based platform designed to facilitate language accessibility at live events through AI captioning and real-time translation. Its primary function is to instantly convert a speaker's speech into readable text, allowing multilingual audiences to follow the presentation on venue screens or through their own personal devices. The tool stands out for its technical simplicity, requiring only one operator and a microphone connected to a computer to manage the session without the need for complex installations.
The operation of Questro | AI Interpreter is powered by an artificial intelligence engine specialized in event contexts. One of its most significant capabilities is its script-aware approach, which allows users to pre-load scripts, speaker notes, or terminology glossaries. Thanks to this technology, the AI improves accuracy by recognizing proper names, acronyms, and specific technical terms before the captions go live. Additionally, it utilizes an alignment system that serves as a backup if the original audio experiences interruptions or poor quality.
Questro’s core capabilities include:
Live automated captions: Immediate transcription of the speaker's voice with minimal latency.
Simultaneous translation: Support for 18 source languages (including Spanish, English, Chinese, German, and French) and translation into 69 target languages.
Flexible display: Captions can be shown on large in-venue screens or via a shared link that attendees open on their mobile devices.
Terminology management: "Vocabulary boost" and "Term lock" tools to ensure that keywords are transcribed correctly.
Stage tools: The ecosystem includes an online teleprompter, synchronized timers, and a Q&A app for audience interaction.
This tool is especially useful for conference organizers, AV teams, and speakers at hybrid or in-person events seeking a scalable language accessibility solution. While the AI delivers high performance, the system is designed for situations requiring assistive captioning; for critical legal or medical contexts, professional interpreter supervision is recommended. Questro simplifies the workflow by allowing any browser-compatible microphone to serve as the input source to generate a complete multilingual experience.
