A screen recorder for teachers that keeps students looking at the right thing.
Record the lesson, the Google Doc or the student's essay from a Chrome tab. Screenix zooms in on what you click, draws a cursor students can follow and gives you a finished video, with no cap on how many you make.

The short answer
Why the zoom matters in a classroom video
Updated October 2026
A tab recording of a document is mostly small text. Screenix zooms in on the spot you click, so a comment in a margin or a cell in a sheet fills the frame.
The cursor is redrawn larger and smoother, so a student watching on a phone can still see where you're pointing.
Your voice, your camera and the page's sound record together, and the camera bubble can sit in a corner or be hidden.
Record as many videos as you want, free, with a small watermark. No account is needed to record.

Step by step
Record a lesson from a Chrome tab
Works the same on a Chromebook, a Windows laptop or a Mac, as long as it runs Chrome.
Step 1
Add Screenix to Chrome
Install it from the Chrome Web Store and pin it to the toolbar. On a school-managed device your administrator has to allow the extension first.
Step 2
Open the material
Slides, a Doc, a Classroom assignment, a website, an interactive simulation. Anything in a tab. Click the Screenix icon, turn on your microphone, and your camera if you want students to see you.
Step 3
Pick Instant or Studio
Instant renders the finished video while you record, zooms included, so a quick explanation is ready the moment you stop. Studio keeps the recording editable for a lesson you want to trim and tidy.
Step 4
Teach
Press Start recording or Alt+Shift+R and work through the page as you normally would. The zoom follows your clicks. Open another tab or a link and the recording follows you.
Step 5
Stop and hand it in
Stop with Alt+Shift+R. Cut the pause at the start or a stumble in the middle, speed up the part where you scroll, then export an MP4 and upload it to Classroom or Drive, or copy a share link with a Screenix yearly or team plan.
Feedback
Video feedback on a student's work in two minutes
Open the student's document, press record, and talk through it while you click on each passage. The zoom lands on the sentence you're discussing, so the student sees exactly what you mean without reading a wall of comments. Instant mode means there's nothing to edit afterwards, the MP4 is ready when you stop.
Because there's no cap on the number of videos, you can do this for a whole class instead of saving recordings for the few that need the most help.
Flipped and absent
Lessons students can rewatch
Record the explanation once in Studio mode, trim the false starts, and export it at 1080p. Students who missed the class, or need to hear it twice, watch it at their own pace. The redrawn cursor and the zoom hold up on a phone screen, which is where many of them will watch.
Speed up the parts where you scroll or wait for a page to load, and the audio keeps its natural pitch.
Where the video lives
Recordings stay on your device until you decide otherwise
Recordings are stored in your browser, on your computer. Nothing is uploaded unless you export a file and put it somewhere, or create a share link. Recording and exporting need no Screenix account.
Share links, when you use them, are hosted by Screenix and need a yearly or team plan. For most classrooms, exporting the MP4 to Google Drive or Classroom is the simpler route and keeps the video inside your school's own tools.
Limits
What a tab recorder won't do
Screenix records browser tabs. It won't record a document camera app, a desktop whiteboard program or anything outside Chrome. For those, use your operating system's recorder. Chrome also refuses to capture some of its own pages, such as settings.
On managed Chromebooks, the administrator can block extension installs, microphone access and developer tools. Screenix needs developer tools allowed, because it captures the page through Chrome's debugging interface. If Add to Chrome is greyed out or recording won't start, that's the reason, and only the admin can change it.
What you get
Every detail of a good demo, handled for you.
Auto zoom
Zooms that follow your clicks
Screenix zooms in on every click and pans with the cursor, so viewers see what you did without squinting. Keep the automatic zooms or move, resize and add your own on the timeline.
Screenix records the page without your system cursor, then draws a crisp macOS-style one in its place, with spring smoothing, click bumps, motion blur and a soft fade when you stop moving. 16 cursor themes, all adjustable.
Open a link, jump to another tab or reload the page. Screenix keeps recording whichever tab is in front in the same window, so a whole flow fits in one take.
Screenix for Chrome records the tab in front of you, so it can draw a perfect cursor over pure page pixels.
Records browser tabs
Screenix captures the page in the tab you're on, at full quality, without your system cursor.
Follows you between tabs
Switch tabs, open links or reload in the same window and the recording keeps going in one take.
Tab audio from the first tab
Your mic and camera record throughout. Page sound comes from the tab you started on.
Not your whole screen
It doesn't capture your desktop, other apps or other windows. On Linux, the Screenix desktop app does.
FAQ
You have questions. We have answers.
Yes. Recording, editing and exporting are free with no limit on the number or length of videos, with a small watermark. A $19 one-time license removes it. There's no education tier because there's no subscription to discount.
If your administrator allows the extension, the microphone and developer tools. Managed Chromebooks can block all three, and a policy that disables developer tools also stops Screenix from capturing the page. Ask them to allow Screenix for Chrome in the Google Admin console.
Yes. Anything that runs in a Chrome tab can be recorded, and the recording follows you if you open another tab or a link.
If you turn on the camera. The bubble can be placed in any corner and resized after recording in Studio mode, or left off entirely.
No. Export an MP4 and share it through Classroom or Drive like any file. Share links hosted by Screenix also open without an account.
No, browser tabs only. For a desktop app or a document camera outside Chrome, use the built-in recorder on your computer.
Screencastify Free caps you at 10 videos of 30 minutes and 5 MP4 exports, and records the system cursor as it moved. Screenix has no caps, redraws the cursor and zooms in on your clicks automatically. If you need quizzes or a Classroom integration, Screencastify is the better fit; Screenix makes the video.
