Lumiko

Lumiko is a browser recorder delivered as a Chrome extension that captures your screen and edits the footage while you work. The website describes it as the ultimate browser recorder: screen capture with automatic cursor zoom and panning, a webcam overlay included, and a screen recording editor built in. It is made for people who record demos, walkthroughs, tutorials, and other screen-based videos and want them to look polished without the effort of manual video editing. According to the site, Lumiko records your screen and edits the footage while you work, tracking your cursor and clicks and then building smooth zoom and pan moves over them automatically. Everything from recording to export happens in the browser. Traditional screen recording is a two-step chore. First you capture the screen, then you spend time in a separate editor adding zoom and pan keyframes so viewers can actually follow the details of what you are showing. That manual keyframing is slow and fiddly, and the result is often static footage that loses the viewer's attention. Lumiko's approach is to analyze the cursor and clicks recorded during your session and turn those movements into automatic camera moves. The site frames this as footage that effectively edits itself: the tracking information gathered while you work becomes smooth zoom and pan animation, removing the keyframe step entirely. Because the zoom is driven by where you actually clicked and moved, it points at the parts of the screen that mattered at the moment they mattered, which is precisely the work a human editor would otherwise have to reconstruct by hand. The recording core is deliberately unrestricted. Unlimited recording lets you capture your entire screen with zero time limits, and audio recording captures system audio and microphone voiceovers together, so narration and on-screen sound stay in one file. The headline capability is Magic Auto-Zoom, also described as Auto Zoom & Pan: Lumiko analyzes your cursor and clicks and then creates smooth cinematic zoom with silky-smooth pans that guide viewer focus automatically based on your clicks, with no manual keyframes required. On top of that, click effects such as Ripple, Orb, or Pressure animations can be applied to every mouse click, giving each interaction a visible cue that helps a viewer track the flow of a demo. Smart Blur addresses the risk of recording a screen that contains things it should not contain. You draw a box and Lumiko instantly obscures sensitive information such as API keys, emails, passwords, and revenue dashboards. Because screen recordings frequently pass over credentials in a terminal, customer emails in an inbox, or internal dashboards, this automated privacy blur removes a manual editing step that would otherwise be needed before a video can be shared. The site lists Smart Blur as part of the Free tier, framed as "Smart Blur & Webcam" under the promise to "hide sensitive info and add a draggable camera overlay," and it also appears as a Pro feature, so the ability to hide sensitive data is not gated behind the paid upgrade. The Instant Editor is a lightning-fast, browser-based timeline editor. It lets you split clips, delete mistakes, trim dead space with the timeline scissors, and drag to reorder segments seamlessly. The same editor handles presentation: beautiful backgrounds can be a preset gradient, a solid color, a transparent background, or a high-res Unsplash image, and you can upload your own company brand assets or logo to make your video pop. Multiple aspect ratios let you export the exact same video in 16:9 for YouTube, 9:16 for Shorts and TikTok, or 1:1 for LinkedIn using intelligent auto-framing. A webcam overlay adds a draggable, resizable circular face-cam with a premium drop-shadow that stays perfectly synced with your screen to add a personal touch to demos. Export options run from 720p and 1080p up to 1440p and 4K, in one click with zero render queue. Lumiko works locally. Recording and export processing happen in the browser, and the site states that recordings are not uploaded, viewed, or retained, and that there is no account and no upload queue. Rendering is hardware-accelerated and local, so your video never goes to the cloud; the company says exports in 4K happen instantly with zero waiting queues. The extension is built on Chrome Manifest V3 and requests the activeTab, storage, desktopCapture, and scripting permissions, with no tracking. The workflow is therefore straightforward: record the screen and audio, let the auto-zoom engine build the camera moves from your cursor and clicks, refine the result on the browser timeline, then export at the resolution and aspect ratio you need. The payoff is speed and polish without a rendering pipeline. Instead of keyframing zoom by hand, creators get cinematic pans and zooms derived from the cursor and click data they already produced while demonstrating a product or explaining a process. Trimming, splitting, and reordering happen instantly in the browser rather than in a queue, and the free tier covers unlimited recording, auto-zoom, Smart Blur, custom backgrounds, and exports up to 1440p. Pro removes the "Made with Lumiko" watermark for clean, white-labeled exports and unlocks full 4K rendering, which matters when video is delivered to clients or published on a brand channel where a third-party badge would be out of place. Concrete scenarios implied by the site include demo videos and product walkthroughs where click effects and auto-zoom direct attention to the right control at the right moment; tutorials and educational recordings where a screen share plus microphone voiceover need to stay in sync in a single file; and client-facing videos where white-labeled exports and custom brand backgrounds are required. Social publishing is a natural fit because one recording can be exported in 16:9 for YouTube, 9:16 for Shorts and TikTok, and 1:1 for LinkedIn with intelligent auto-framing, avoiding a re-record for each channel. Recordings of environments containing credentials, emails, or revenue dashboards are covered by Smart Blur, and talking-head style demos use the draggable webcam overlay. Lumiko targets makers: its footer reads "Built for makers," and the feature set points at product teams, developers, founders, marketers, teachers, and anyone else producing screen-based video. It runs as a Chrome extension on Manifest V3 and processes everything locally in the browser. Pricing is free to start: the Free tier is $0 forever with no sign-up required and includes unlimited recording, the auto-zoom engine, Smart Blur and webcam overlay, and exports up to 1440p. Pro is offered as a lifetime license rather than a subscription; the feature section lists Pro at $29 lifetime, while the pricing section and FAQ present it at $9 one-time, forever, including no watermark, 4K Ultra-HD exports, and up to 3 device activations. Lumiko's value proposition is a screen recorder whose footage edits itself with auto zoom and pan, backed by a browser editor, privacy blur, webcam overlay, backgrounds, click effects, and local 4K rendering. Combined with a free tier and a one-time Pro upgrade, it is aimed at makers who want professional-looking screen videos without keyframes, subscriptions, or cloud uploads.
