Nator

Bilingual subtitles and contextual explanations for YouTube.

Understand more of every YouTube video with Nator. Nator brings bilingual subtitles and concise explanations of important terms directly into the player. Choose your language, adjust subtitle size, and select Beginner, Familiar or Advanced to control how much context you see. Your language starts from your browser language and remembers your choice. • Follow original and translated subtitles together. • See key concepts explained in the context of the video. • Scroll through generated explanation cards while the video continues. • Sign in with Google to save cards and qualifying watched videos to your personal library at nator.aplomo.ai. Your language preference stays in sync. • Customize original captions, font size and explanation background. Try 30 minutes of AI-assisted playback without an account. Sign in for 200 minutes per UTC week. Pauses, ads, buffering and seek jumps do not count. Subscription plans are coming soon; payments are not currently enabled. AI processing begins only after you agree to the in-extension disclosure. Captions, video title, channel and selected languages are sent through Nator and Pipixia AI to the configured model provider. Available on-device translation stays on your device. AI output may be inaccurate. Requires desktop Chrome 138 or later and a recorded YouTube video with available captions. Videos without captions are not supported. Previously published as Miau&Poli, this update replaces the old subtitle side panel and export tools with Nator's in-player learning experience.
