Lumiko

Lumiko is a Chrome screen recorder that automatically follows the cursor with cinematic zoom and pan, adds click animations, trims dead space, and can blur sensitive on-screen data. It processes locally in the browser and is free with a one-time Pro upgrade for 4K and watermark-free exports.

Lumiko is a browser-based screen recorder delivered as a Chrome (Manifest V3) extension, built for makers who want polished product demos and tutorials without a heavy desktop editor. Its signature feature is an auto-zoom engine that analyzes cursor movement and clicks to produce smooth, cinematic zoom and pan, so the viewer eye is guided to the right spot without manual keyframing. Beyond capture, Lumiko includes a lightweight editor for trimming dead space with timeline scissors, click effects such as ripple, orb, and pressure animations, custom backdrops including gradients and images, and an optional draggable circular webcam overlay. A smart blur tool can obscure sensitive on-screen information such as API keys, emails, passwords, and dashboards before export. Recording and rendering are handled locally in the browser, and Lumiko states it does not upload, view, or retain recordings. Lumiko is free forever for unlimited recording and the auto-zoom engine, with exports up to 720p. A one-time Pro upgrade unlocks higher-resolution rendering up to 4K, removes the watermark, and adds the smart blur tool and webcam overlay, with a lifetime license covering up to three device activations. It is a strong fit for solo founders, developers, and support teams who want fast, good-looking demo videos from the browser, and less suited to those who need a full multi-track desktop video editor or native mobile capture.
