What the product does and how it is positioned
Lumiko is a browser extension and recording utility built on Chrome Manifest V3 that captures screen activity, webcam feeds, and microphone and system audio. It offers a browser-based alternative to desktop screen-casting suites by handling both video capture and basic post-production editing inside the browser.
The tool emphasizes presentation polish and privacy by automatically panning and zooming to follow mouse activity, allowing selective blur boxes over private data, and rendering finished video locally with hardware acceleration instead of sending footage to cloud servers.
Source-supported ways to use the product
Record software product walk-throughs using automatic cursor zooming and a synchronized circular webcam overlay to guide audience attention.
Reformat recorded screen content into 16:9, 9:16, or 1:1 aspect ratios with auto-framing for distribution across platforms like YouTube, TikTok, and LinkedIn.
Conceal sensitive environment variables, credentials, or customer data using manual blur boxes prior to exporting client or team videos.
Lumiko operates as a Chrome Manifest V3 extension, capturing screen media alongside system audio, microphone input, and an optional circular webcam overlay. Rather than sending raw or edited video to remote servers for processing, all timeline manipulations and export rendering steps execute locally within the user's browser environment using hardware acceleration.
The integrated editor allows users to trim dead space, split recorded segments, and reorder clips directly on the browser timeline. Users can also configure visual enhancements including animated click feedback, preset or custom brand backdrops, and auto-framed exports across widescreen, vertical, and square aspect ratios.
Checks to run with your own material and workflow
What was checked and when
Answers based on the source-checked product record
No. All screen recording capture and export rendering occur locally within the browser, and recordings are not uploaded, viewed, or retained on remote servers.
Lumiko supports exports in 720p, 1080p, 1440p, and 4K resolutions, with the free tier supporting up to 1440p and 4K rendering available in the Pro tier.
Lumiko tracks cursor movement and click events throughout the screen capture to generate automatic zooming and panning transitions without manual keyframing.
The browser timeline editor provides tools to trim sections, split recordings, delete errors, and drag segments to reorder the sequence before final export.
Users can draw a box over private details such as API keys, email addresses, passwords, or financial metrics to apply a blur effect over that section of the video.
