Lumiko is a browser screen recording tool positioned as the "ultimate browser recorder," installed and used as a Chrome extension. It integrates screen capture, auto-zooming camera language, privacy blurring, webcam overlay, and built-in editing into a single extension, with recording and export done locally.
In terms of use, Lumiko is aimed at users who need to create screen presentations, tutorials, and product demos, guiding viewers' attention through automated panning and zooming and reducing the effort of manually editing keyframes.
Main capabilities:
- Auto zoom and pan: analyzes cursor position and click actions to automatically generate smooth cinematic zooms, with no need to manually set keyframes.
- Privacy blur: can instantly mask sensitive information such as API keys, emails, passwords, and revenue dashboards using box selection, and provides automatic privacy blurring.
- Built-in editor: a browser-based timeline editor that supports trimming, splitting, deleting bad segments, and dragging to reorder clips.
- Webcam overlay: a draggable, resizable circular face camera view with shadow effects, synchronized with the screen content.
- Backgrounds and aspect ratios: choose from preset gradients, Unsplash HD images, or upload brand assets; supports export in 16:9, 9:16, and 1:1 ratios, with smart auto-framing.
- Local rendering: hardware-accelerated local rendering, videos are not uploaded to the cloud, supports one-click export in 4K, 1080p, or 720p, with no render queue waiting.
How to use: after installing it as a Chrome extension, record the entire screen, an external monitor, or any standalone desktop app (such as VS Code, Terminal, Figma, Slack, etc.) via Chrome desktopCapture, and automatically apply cursor zoom. The official description states that recording and export processing are both performed locally in the browser, and the screen recording content is not uploaded, viewed, or retained.
Use cases: creating tutorials, product demos, client delivery videos, short-video platform content (Shorts, TikTok, LinkedIn), and other screen recordings that require clear focus guidance.
Pricing and limitations: the free version allows unlimited recording time and includes auto zoom, smart blur, and custom backgrounds, with export up to 1440p, but it has a "Made with Lumiko" watermark. The Pro version is currently a one-time purchase of $9 (originally $29), unlocking clean export without a watermark below 4K, rendering up to 4K, and support for a lifetime license on 3 different computers. Subscriptions, renewals, or other recurring fees: the official statement clearly says there is no subscription. Details such as export formats and operating system compatibility (other than the Chrome extension) have not yet been provided.
