SaySame Live Interpreter

Live translate any video with translated voice or cheap text mode.

Watch videos in any language. SaySame is a live, real-time translator that drops a small bar onto your video and translates the audio as you watch — no waiting, no human captioners, no separate apps. Powered by OpenAI's Realtime Translation API. WHAT IT DOES • Voice mode — hear the translated speech alongside the video. The translated voice automatically follows the source speaker's tone. • Text mode — see translated captions only, no voice. About 40% cheaper than voice mode if you don't need to hear it out loud. • Live cost ticker — see exactly what each session is costing you, second by second. No surprises on your bill. • Mid-session language switch — change your target language without restarting the session. • Resizable, draggable, transparent bar — set it up so it doesn't get in the way of what you're watching. Position and size persist across sessions. • Live captions with show/hide toggle in voice mode. • Independent volume sliders for the original audio and the translated voice — mix them however you want. WHERE IT WORKS SaySame works on most popular video platforms, including YouTube, Bilibili, Xiaohongshu, and Douyin. The full list of supported sites is on the project's GitHub repository: https://github.com/fanispoulinakisai-boop/saysame WHO IT'S FOR • Language learners watching content in the language they're learning. • Researchers and journalists tracking foreign-language news, podcasts, and lectures. • Developers following technical tutorials that aren't in their native language. • Anyone who wants to enjoy the large portion of the internet's video content that isn't in a language they speak. PRIVACY-FIRST DESIGN • Your OpenAI API key is stored locally in your own browser. It never leaves your device except to authenticate with the translation service. • Audio is streamed directly from your browser to the translation service — we never see, route, or log any of your video, audio, or translations. • Zero analytics. Zero tracking. Zero third parties. • Full privacy policy: https://github.com/fanispoulinakisai-boop/saysame/blob/main/PRIVACY.md WHAT YOU NEED • A Chromium-based browser. • An API key with access to OpenAI's Realtime API. Get one at https://platform.openai.com/api-keys — typical cost is around $0.034 per minute for voice mode and around $0.02 per minute for text mode. • A video on a supported site.
