Video-Essenz: YouTube-Zusammenfassungen mit KI von dnmsk

You don't need to watch the video. You need to know what's in it.

Video Gist grabs the transcript of any YouTube video and hands it to the AI you
already use — DeepSeek, ChatGPT, or Claude — in one click. You read the gist in
seconds, in the language you choose.

And it doesn't stop at a summary: because it opens a real chat, you can discuss
the video with the AI — ask follow-ups, challenge it, dig into details, pull out
quotes. A one-shot recap turns into a conversation about what you just (didn't)
watch.

No API keys. No extra subscription. No account on our side. It uses your existing
AI session right in the browser: opens a fresh chat, attaches the transcript, and
asks the question for you.

WHAT YOU GET
• One button on every youtube.com/watch page — the gist, on demand
• Pick your AI: DeepSeek · ChatGPT · Claude — with a live login indicator
(green = ready to go)
• Choose your language — ask and read the summary in English, Русский, Deutsch,
Español or 中文, switchable any time
• Discuss, don't just skim — it's a real chat, so ask anything about the video
• A fresh chat per video — clean context, no clutter
• Works in Chrome and Firefox

WHY IT'S DIFFERENT
Most "summarizers" route your data through their servers and bill you by the
token. This one doesn't. The transcript goes straight from your browser into your
own AI chat. We don't see it. We don't store it. We don't even run a server that
could.

HOW IT WORKS
Click → the extension reads the video's subtitles → opens a new chat in your
chosen AI → attaches the transcript → asks for the gist. Read the answer, then
keep the conversation going.

Requires an active login to at least one of: DeepSeek, ChatGPT, Claude.

No bloat. Vanilla JS, Manifest V3. Your time is the product — not your data.
