1. Open the device
Enter its IP address, such as 192.168.6.223, or a full URL. Your computer must be on the same network for a local device. Log in and configure it using its normal interface.
2. Capture the screen
Click Capture. On the first capture, your browser asks which tab or window to share. Choose this app’s tab when the device is open inside it. Keep the sharing session active for the next capture. Each new capture starts with the full image. To reuse a crop, turn on Reuse my crop on the next capture in Capture options.
If the device blocks embedding, use More → Open device in a separate tab. In Capture options, choose Device in a separate tab, then select that tab in the browser picker. Use the original tab to operate the device; its shared preview is a video view.
3. Annotate, crop, and export — in any order
Images open with Select active. Pick an annotation tool whenever you like, and use Crop when you want to change the frame. Cropping keeps your annotations editable; reset the crop to see the full image again. Draw holds arrows, shapes, highlights, blur, spotlight, and solid redaction. Blur softens the screenshot beneath your marks; use solid redaction for private details. Text adds labels, callouts, and stamps. Steps adds numbered or lettered markers, and Stickers adds icons. Choose Select to move or resize a mark. Style changes its color, stroke, fill, and opacity.
Use Finish for margins, rounded corners, a shadow, or a window frame. Preview the result, then click Download for WebP or Copy for PNG. The export menu also offers PNG and JPEG. The adjacent export menu contains format, size, and quality options. Your crop, annotations, and finishing touches appear in the exported image.

Hold Space and drag to pan. Drag inside a crop to move it; Alt+drag draws a new crop. Double-click a text label with Select to edit it.
Use Lerim locally
Choose More → Download app (.html) to save Lerim-V1.html. Open that file in your browser, then enter your device’s IP address. The downloaded app includes its tools, icons, and animations; no installation or internet connection is needed to open it.
Your computer still needs a connection to the device’s network. The downloaded copy starts fresh. Use Save project to keep an image with editable annotations.
If your device page does not open inside Lerim, use More → Open device in a separate tab and choose that tab as the capture source.
Browser and project notes
Capture includes the visible screen; it does not scroll or stitch pages. Browser sharing, clipboard access, local-file permissions, and certificates depend on your browser. A current desktop Chrome or Edge is recommended. This app cannot bypass a device’s embedding restrictions or certificate errors.
Image editing stays in this browser. Device pages make their normal network connections. If screen capture is unavailable, open or paste an existing image.
Editable projects include the original, unredacted image. Keep project files private; share an exported image when you need the redactions applied.
