Trancy

Trancy offers a browser extension and related learning portals for language-learning scenarios. It can display bilingual subtitles on supported platforms and help users understand video content through theater or reading modes; the reading mode organizes subtitles into more easily digestible text.

While reading web pages, you can highlight words, sentences, or the entire text for simultaneous translation, and save highlighted phrases, review grammar, or practice shadowing. These features depend on the selected translation engine, website, and membership plan; therefore, support on one platform cannot be automatically assumed to enable unconditional transcription of any video.

The official website separates basic translation from advanced AI features, subtitle transcription, PDF handling, and more. Custom external engines or API keys may also be subject to the provider’s pricing and quota limits, and should be distinguished from Trancy’s membership benefits.

2026-10-24 Verification of the official pricing page: Basic features are available free of charge, while premium AI, video transcription, PDF support, and other benefits are tiered according to membership plans. The dynamic “0 yuan” placeholder shown on the page should not be regarded as the actual membership price; therefore, unconfirmed monthly and annual fees are not listed. Fees for service providers with their own API keys are billed separately. Source: https://www.trancy.org/zh-cn/pricing
