Sayso.

Hear it. Keep it. Say it.

Learn English from the YouTube videos you actually want to watch.

Open Sayso

01 / A real need

“I could understand the video.
But could I say it myself?”

I kept hearing great words and phrases on YouTube, only to forget them a few days later. When it was time to speak, I fell back on the same familiar vocabulary.

Sayso — learn English from the videos you want to watch. Study, Shadow, Review, Talk.
02 / An idea in motion — Hear → Keep → Say

03 / A working product

From watching
to actually speaking.

I didn’t need another list of words to memorize. I wanted the phrases from my own videos to come back when I needed them.

So I built Sayso for myself: a way to turn videos I enjoy into something I can remember and actually use. One learning loop, from the first listen to a conversation of my own.
