Lumiko

Lumiko is a free Chrome screen recorder and browser-based video editor that turns ordinary screen captures into polished, cinematic recordings. It is built for anyone who needs to show a screen — creators, developers, marketers, designers, founders, educators, and freelancers producing demos or client work — and its core promise is simple: you record your screen, and Lumiko edits the footage while you work. The extension captures your screen together with system audio and microphone voiceover, tracks where your cursor moves and clicks, and then automatically builds smooth zoom and pan moves over those moments, so the finished video guides the viewer's attention without any manual keyframing. A built-in editor in the browser lets you trim, split, and reorder clips, add a webcam bubble, apply backgrounds and click effects, and export up to 4K, all without creating an account or uploading anything to a queue. Traditional screen recording workflows are slow and fiddly. Recording is the easy part; making the result watchable is not. Editors normally have to scrub through the timeline, place keyframes by hand to zoom into the parts that matter, mask out anything sensitive, and then wait for a render before the file is ready to share. Cloud-based recorders add another layer of friction: clips go to a server, upload queues build up, accounts are required, and privacy becomes a question. Lumiko addresses this by treating the cursor and the clicks as the editing signal. Because the recording itself carries the information about where attention was, Lumiko can automate the zoom and pan work that would otherwise be done by hand, and it can do all of the processing locally in the browser rather than in the cloud. Auto Zoom & Pan is the headline feature. Lumiko analyzes your cursor and your clicks as you record, then creates smooth, cinematic zoom and pan moves that follow them automatically — no manual keyframes and no timeline gymnastics. The result is a recording that stays on the part of the screen that matters, guiding viewer focus the way a human editor would. Paired with this are click effects: ripple, orb, or pressure animations triggered on every mouse click, which make interactions visible and obvious to someone watching the video. Together these two capabilities mean a plain screen capture reads as a directed piece of footage rather than a flat, unedited dump of a desktop, which is especially valuable for demo videos where the viewer needs to understand exactly what was clicked and in what order. Smart Blur handles privacy. Drawing a box hides sensitive information such as API keys, emails, passwords, and revenue dashboards, with the stated purpose of obscuring that data instantly and automatically. For developers recording a terminal, a dashboard, or a settings screen, this removes the risk of leaking credentials or customer data in a published video. The Webcam Overlay adds a personal element: a draggable, resizable circular face-cam frame with a premium drop-shadow that stays perfectly synced with your screen recording. Because it can be moved and resized, it can be placed wherever it does not cover the part of the screen being demonstrated, giving the recording a presenter presence without requiring a separate camera setup or external compositing software. The Instant Editor is a browser-based timeline that runs with zero render queue. You can split clips, delete mistakes, and drag to reorder segments, then export in 4K, 1080p, or 720p in one click. Basic trimming with the timeline scissors removes dead space immediately. Beautiful Backgrounds lets you frame the recording with a preset gradient, a solid color, a transparent backdrop, a high-resolution Unsplash image, or your own uploaded brand assets, including a company logo. Multiple Aspect Ratios means the same video can be exported in 16:9 for YouTube, 9:16 for Shorts and TikTok, or 1:1 for LinkedIn, using intelligent auto-framing so the composition holds up in each format. Rendering is hardware-accelerated and local, so exports happen on your machine rather than through a cloud render farm. Overall, Lumiko is a Chrome extension built on Manifest V3 that works as a single integrated tool: record, edit, and export without leaving the browser. During recording it captures the screen and, on the free tier, system audio and microphone voiceover together. Because it tracks the cursor and clicks, it can generate the zoom and pan choreography as part of the recording rather than after it, which is what removes the keyframing step entirely. Editing then happens in the browser-based timeline, and export is performed with hardware-accelerated local rendering. Lumiko requests only four permissions — activeTab, storage, desktopCapture, and scripting — and states that there is no tracking, that recording and export processing happen locally in your browser, and that recordings are never uploaded, viewed, or retained. The practical benefits follow from that design. Creators get cinematic-looking recordings without learning an editor or placing a single keyframe. Because there is no render queue and no upload step, the gap between finishing a recording and sharing it shrinks considerably. Privacy is protected by default: sensitive data is hidden with Smart Blur before it ever leaves the machine, and no account is required to start. The pricing model is equally direct — free forever for unlimited recording, auto-zoom, Smart Blur, custom backgrounds, and exports up to 1440p, with a one-time Pro upgrade for watermark-free 4K exports and a lifetime license covering up to three device activations. There are no subscriptions and no surprise recurring charges, so the cost of producing professional demo videos stays predictable. Concrete workflows include recording product demos and feature walkthroughs where the viewer needs to follow a specific sequence of clicks; producing software tutorials and technical walkthroughs; and capturing bug reports or step-by-step reproductions for teammates. Marketers and founders can repurpose a single recording across channels by exporting it in the correct aspect ratio for YouTube, Shorts, TikTok, or LinkedIn. Freelancers and agencies record client-facing work with custom brand backgrounds, their own logo, no watermark, and a webcam overlay to add a personal introduction. Anyone recording a terminal, admin panel, analytics dashboard, or configuration screen can use Smart Blur to hide API keys, emails, passwords, and revenue figures before publishing. Educators and course creators can record lessons with system audio and voiceover, trim the dead space, and export in HD for a learning platform. Lumiko is aimed at makers — the site signs off with "built for makers" — which in practice covers developers, designers, product teams, marketers, founders, freelancers, agencies, educators, and course creators who publish screen recordings regularly. It runs as a Chrome extension and can be launched from the Chrome Web Store or the browser editor page, so the ecosystem it integrates with is the Chrome browser itself. Backgrounds can draw on preset gradients, solid colors, transparent options, or high-resolution images from Unsplash, and custom uploads for brand assets. Pricing is straightforward: a Free tier at $0 forever with unlimited recording, auto-zoom engine, click effects, timeline editing, Smart Blur, webcam overlay, and exports up to 1440p; and a Pro tier listed at $29 lifetime, discounted to a $9 one-time payment, adding 4K Ultra-HD exports, removal of the "Made with Lumiko" watermark, and a lifetime license with up to three device activations. Lumiko's value proposition is contained in a single idea: the recording edits itself. By turning cursor movement and clicks into automatic zoom and pan, adding Smart Blur, a webcam overlay, backgrounds, aspect-ratio exports, and a local timeline editor, it compresses what used to be a multi-step editing project into a record-and-export workflow that runs entirely in Chrome — free to start, and $9 once to unlock 4K, watermark-free output.
