FAQ
Questions
What is EchoFlow?
EchoFlow is a language-learning tool. Its browser extension turns foreign-language web pages and video subtitles into side-by-side bilingual text, and the full app saves the phrases you meet into a personal phrase library, schedules reviews and lets you practise speaking them aloud.
How is it different from a regular page translator?
EchoFlow translates only the paragraphs you are reading, lets you switch between original, bilingual and translation-only views, and colours matching phrase chunks in both languages so you can see how an idea is expressed. Phrases you like can be saved with their source for later review and shadowing.
Which browsers and devices are supported?
Chrome and Edge extensions can be installed today, and the full macOS app is available to download; the Safari extension ships with the Apple app. Public iPhone/iPad testing, a Windows desktop app, Android and Firefox are still in preparation.
How much does it cost?
Installing the extension and app is free. Cloud translation uses account credit: Plus is ¥19 per 30 days for 2 million credits and Pro is ¥49 per 30 days for 8 million credits. Plans are activated after manual payment confirmation and do not auto-renew.
What happens to my data?
Text you choose to translate is sent through EchoFlow's Shanghai server to DeepSeek. Page text and translations are not written to access logs, and learning records stay on your device or in your existing iCloud path.
