The Challenge

Recording a Google Meet call or other browser audio often means complicated setups, separate desktop software, or cloud services that upload conversations to someone else's servers. For people handling client calls, interviews, internal reviews or learning sessions, that raises privacy concerns and adds friction to what should be a simple task. The goal was a lightweight way to capture tab audio directly on the user's own device. It needed no login, no subscription and no background tracking, and it had to produce clean audio files that work well in later transcription workflows.

Our Approach

We built Chromodio as a focused Chrome extension that does one job well. Every design decision kept recording local: no servers, no uploads and no account creation. The workflow is reduced to four steps: join the call, click Record, click Stop, and save the file. The extension captures audio from the active tab, whether that is Google Meet, YouTube or another site. Users can optionally mix in their microphone so both sides of a conversation are recorded. The output is a standard .webm audio file that users can keep for their records or pass to transcription tools such as Whisper.

What We Built

One-click recording controls for capturing tab audio from Google Meet, YouTube and other sites
Optional microphone mixing to record the user's voice alongside tab audio
A live recording timer so users always know how long they have been recording
Instant local save as a .webm audio file, with no cloud upload
No login or setup required. The extension works immediately after installation
A published Chrome Web Store listing with clear privacy and support information

More about this project

Technology

Chromodio is built with JavaScript, HTML5 and CSS3 as a Chrome Extension on Manifest V3, which is the current extension platform Chrome requires for new submissions. Chrome APIs give the extension controlled access to tab audio inside the browser, so users do not need separate recording software. The Web Audio API combines the tab stream with the optional microphone input. The MediaRecorder API encodes the result directly into a .webm file on the user's machine. Because the whole pipeline runs in the browser with native web technologies, the extension stays lightweight and needs no backend infrastructure. This is how it delivers its central promise that recordings never leave the user's system.
