The Problem

You forget 90%
of what you watch.

Passive viewing — autoplay, 1.5×, half-listening — creates the illusion of learning. Your brain doesn't engage. It barely stores. The insight evaporates the moment the video ends.

You finish a 1-hour lecture but can't summarize the thesis
You re-watch the same segment 3 times to find one quote
You binge a course playlist and remember the intro

Features

Everything you need
to understand deeply.

Not a chatbot. Not a summarizer. A thinking partner for every video you watch.

Ask Anything

Ask follow-up questions, request examples, probe assumptions. Your videos become conversation partners.

Deep Explanation Mode

Go beyond surface understanding. Ask YEMTI to explain concepts from first principles.

Voice Conversation

Speak your questions naturally. Discuss a video while you walk, commute, or work out.

Multi-language Discussion

Watch in any language, chat in yours. 50+ languages supported for transcription and conversation.

Contextual Memory

YEMTI remembers previous questions in your session. Conversations build on themselves.

Challenge Ideas

Don't just absorb — engage. Ask YEMTI to argue the opposite, find weaknesses, steelman arguments.

Timestamped Citations

Every answer is grounded in the video, with a timestamp you can click to jump to the exact moment.

How it works

Add → Ask → Understand → Master.

Four steps. Two minutes. A fundamentally different relationship with the videos you watch.

Ask anything in plain English (or any language). No timestamps to scrub. No keywords. Just questions.

Text or voice. 50+ languages supported.
03

Understand

Grounded answers + timestamps

Get precise answers grounded in the video. Every answer cites the exact moment. Jump straight there.

Answers include timestamps and citations.
04

Test & reinforce

Auto-generated quizzes from the video. Ask YEMTI to test you. Lock in what you've watched.

Spaced repetition mode coming soon.
Showcase

Talk to the video.
Right inside the player.

Ask from the player bar. YEMTI pauses your video and replies with its own — voice, avatar, timestamps. All in the same player.

“Self-attention lets every token look at every other token in parallel — that’s why it killed recurrence. Skip to 12:48 in the lecture.”
