YouTube aggressively auto-translates content (titles, descriptions, thumbnails, audio tracks, subtitles) for users in non-English locales or with certain language settings. This is disruptive for multilingual users, language learners, and anyone who prefers consuming content in its original language.

Install extension → all features are enabled by default (except subtitles) → browse YouTube normally; titles, descriptions, thumbnails, and audio remain in original language → optionally configure features via popup toggle switches (original titles, audio track, descriptions, thumbnails, subtitles) → optionally enable YouTube Data API v3 with own API key for more reliable channel name retrieval → extension silently intercepts YouTube's translation/replacement on every page load using MutationObservers and fetch requests to oembed/InnerTube APIs.

Target users: Multilingual YouTube users who understand content in original languages / Language learners who want exposure to content in target languages / Users frustrated by YouTube's automatic translation of video metadata

Deterministic heuristic false positive on 'auth' keyword - all hits were unrelated to extension login (YouTube background auth pages, browser polyfill, author field)
Deterministic heuristic false positive on 'subscription' keyword - all hits were YouTube '/feed/subscriptions' page paths, not paid subscriptions
The optional YouTube Data API key requires users to obtain their own Google API key (free tier available), but this is not a paid feature of the extension itself

Monetization

No paid features detected

The extension is explicitly described as 'free to use' in the store listing. All features (titles, audio, descriptions, thumbnails, subtitles) are available without any payment. Ko-fi links throughout the codebase are purely optional voluntary donations ('pay-what-you-want contribution'). The askForSupport toast is a periodic donation reminder that can be permanently dismissed, not a paywall. No premium tiers, no gated features, no billing/payment APIs, no Stripe/stripe references, no license checks. The 'subscription' keyword matches are all YouTube '/feed/subscriptions' page paths, not paid subscriptions.

Confidence: 97
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates directly on YouTube pages via content scripts with no login UI, no account creation, and no authentication flow. It only requires the 'storage' permission for local settings. The 'auth' keyword hits in the heuristic are false positives: CHANGELOG.md references YouTube's own 'background auth pages' (lines 65, 76), browser-polyfill.js contains a standard 'launchWebAuthFlow' API polyfill (line 355), and manifest.json 'author' field (line 6) contains 'YouGo'. No login is needed to use any core feature.
