What makes your product unique?

SonicCaption's answer:

SonicCaption adds real-time bilingual captions as a lightweight overlay on top of the website youโ€™re already using. Itโ€™s designed to work across platforms (videos, meetings, livestreams) instead of being tied to a single app, so you donโ€™t need uploads, downloads, or switching tools.

Why should a person choose your product over its competitors?

SonicCaption's answer:

Itโ€™s fast to start, works on more sites, and stays out of the way. You get clear live captions with optional translation in one place, with a simple browser-extension workflowโ€”open a tab, choose languages, and read alongโ€”ideal for learning and understanding without disrupting the content.

How would you describe the primary audience of your product?

SonicCaption's answer:

Language learners, international professionals, and global teams who watch videos or attend meetings in a non-native language and need real-time understanding. Also useful for anyone who wants clearer comprehension in webinars, online courses, and cross-border calls.

What's the story behind your product?

I built SonicCaption because I regularly watch courses and join meetings in languages Iโ€™m not fluent in. Existing tools were either platform-specific or required extra steps. I wanted something that works anywhere in the browser and helps me understand instantly with minimal friction.

Which are the primary technologies used for building your product?

SonicCaption's answer:

Chrome/Edge extension (Manifest V3), real-time streaming speech-to-text, machine translation, and a web backend for session management and billing. The product focuses on low-latency audio capture + streaming transcription to deliver captions in real time.
