Seagull is a real-time translation overlay application that captures audio from any source on your computer and displays translated subtitles instantly. It functions like captions for your entire desktop, allowing users to understand audio content in foreign languages without needing specialized plugins or browser extensions.

The application supports over 60 languages including English, Mandarin, Swahili, and Tagalog. It captures system audio from any application without requiring plugins or browser extensions. The transparent overlay floats above all windows and can be dragged anywhere on screen. Voice playback with natural voices and adaptive speed that keeps pace with the audio are coming soon as paid add-ons.

Seagull works by capturing system audio silently in the background and translating it in real-time. Users simply open the application, play audio from any source, and read along with the translated subtitles that appear instantly on screen. The process requires zero setup with no wizards, onboarding flows, or tutorials needed.

The product enables users to follow along with foreign-language podcasts, get better-than-auto-caption translations for YouTube videos, understand multilingual team meetings on platforms like Zoom and Teams, never miss words in online lectures and courses, understand voice chat in games across languages, and add subtitles to movies from any streaming service.

Seagull targets users who listen to foreign-language content including podcast listeners, YouTube viewers, remote team members in multilingual meetings, students taking online courses, gamers communicating internationally, and movie watchers streaming content from different regions.
