Skip the watching.
Keep the knowing.
Summexa reads the video the moment you open it, then slides a clear written summary in next to the player. No watching required, nothing to configure.
How it works
Open any video
Go to YouTube like you always do. Summexa only appears on an actual video page, nowhere else.
Click the small icon
It sits quietly beside the player, never on top of the video you are watching.
Read what matters
A clear, structured summary slides in. Skim it in less time than the video takes to buffer.
A 14 minute video. Two ways to know it.
Watching it
Full playback, start to finish, even for the parts that do not apply to you.
Reading the summary
The structure of the video, kept, the padding, gone.
What the sidebar is doing while the video plays

Shows the before and after numbers, then wraps up.
From spoken words to something you can read
Video
You open a YouTube video and click the Summexa button. Only the video ID leaves your browser.
Transcript
An existing transcript is fetched when one is available. If not, the audio is transcribed as a fallback.
Summary
An AI model reads the transcript and writes a clear, structured summary back into the sidebar.
One button. One summary.
Reads it for you
Summexa transcribes the video and writes a clear summary, so you do not have to watch a single frame to know what it says.
Never in the way
One small button, one slim panel. It never covers the video and closes the moment you are done.
Works when captions do not
Some videos ship with messy or missing captions. Summexa falls back to transcribing the audio itself.
Nothing to sign in for
No account, no login, no setup screen. Install it once and it works on the next video you open.
Built for one thing
No chat, no quizzes, no extra tabs to manage. Just the summary you opened the sidebar for.
Matches your system theme
Light or dark, Summexa switches with the rest of your browser so it always looks like it belongs there.
Questions people actually have
Summexa works on any public video that has spoken content. If a video has no captions at all, Summexa falls back to transcribing the audio itself, so it still works, it just takes a little longer.
Sends what it needs. Nothing more.
What Summexa sends
- The ID of the video you are currently watching
- The video's transcript, only if you choose "Open in Harkixsha"
What it never touches
- Your browsing history
- Your Google account or email
- Anything else open in your browser
- Your microphone or camera
Chrome will warn you. That is Chrome, not Summexa.
When you install Summexa, Chrome may show a note that says "This extension is not trusted by Enhanced Safe Browsing." That is Google's default caution for any extension that has not built up install history yet, applied automatically, the same note every extension gets on day one.
