About this app

Turn your YouTube 'Binge-watching' into English fluency.
Let’s be honest: You spend hours on YouTube watching your favorite creators, movie clips, or vlogs anyway. Why not use that time to finally fix your English?

Saylo isn't another app that makes you memorize boring word lists or solve grammar puzzles. We believe in one simple thing: If you want to speak like a native, you have to mimic a native.

Mastering a language is a game of mimicry. Saylo makes it easy:

- WATCH: Enjoy the YouTube content you actually love (MrBeast, TED, Movies, Music).
- UNDERSTAND: Get instant bilingual subtitles and local language explanations.
- SHADOW: Mimic native speakers with our AI-powered ""Shadowing"" tool.
- FLOW: Compare your speech with the original and achieve a natural flow.


Why Saylo?
- Zero Grammar Focus: Stop memorizing formulas. Build your ""language intuition"" naturally, the same way you learned your first language.
- AI Speaking Analysis: Get instant feedback on your pronunciation and rhythm. Our AI helps you sound more like a native, one sentence at a time.
- Smart Subtitles: Tap any word to see what it means in your language. No more switching back and forth to a dictionary. Everything you need is right on the screen.
- Real Slang: Learn the expressions native speakers use daily, not the stuff from outdated textbooks.
- Bite-sized Lessons: Got 5 minutes on the bus or waiting for coffee? That’s a lesson.

Tailored for You We make English easy to understand by providing meanings and support in your native tongue, including: Vietnamese | Thai | Chinese (Traditional & Simplified) | Japanese | Korean

Stop studying English. Start living it. Download Saylo and find your English voice today.
