The problem

You watch it. You forget it.

A good video, a brilliant idea — and a week later, gone. You're not alone.

Watched, then vanished

The more you consume, the less you remember. When you need it, you can't find it.

Buried in hours of video

The one line you need is 13 minutes into a 20-minute clip. Scrubbing back is painful.

No way to build on it

Taking notes breaks the flow. Not taking notes means nothing sticks.

How it works

One tool. Three simple steps.

01 · Capture

Paste a link. Get a transcript.

Drop any video URL — YouTube, TikTok, Bilibili, Xiaohongshu, and more. No downloads. No extensions required. Accurate transcripts in under 30 seconds.

02 · Distill

AI pulls out what matters.

Not just a transcript. Structured summaries, key quotes, timestamped highlights. Read a 40-minute video in 3 minutes.

Ember is a personal knowledge tool. We don't store original videos — only transcripts you generate for your own use. You're responsible for the links you submit, and transcripts must not be used for commercial infringement.

Those tools transcribe audio and video you record yourself. Ember is built for transcribing public videos you find online — across platforms — and turning them into a searchable knowledge base. They're complementary, not competing.

All transcripts are private by default — only you can see them. Sharing is opt-in and can be revoked at any time. We never sell or share your data with third parties.

Subscriptions are refundable within 7 days, no questions asked. Credits, once used, are non-refundable.
