  "account": "A Firefox extension called Built Voice Notes & Audio Recorder has been created to simplify quick voice memos for remote workers, students, and others who prefer speaking over typing. This extension offers several key features without requiring any account, cloud service, or subscription.\n\nTo use the extension, users simply click the toolbar to begin and stop recording. The voice notes are saved locally within the browser, with each note accessible for playback and deletion directly from the extension's popup. Users have the option to export the recording as a WAV file if needed.\n\nThe extension leverages the Web Audio API and MediaRecorder to handle audio recording and processing. It requests microphone permission at the moment of recording, rather than during installation, providing a seamless user experience. The stored recordings are kept in Firefox's local storage, with a maximum capacity of around 40-50 one-minute recordings due to storage limitations.\n\nPlayback is managed by converting the base64 audio data back into a Blob and playing it through an audio element in the extension's interface. While the extension does not currently offer transcription or search functionality, these could be potential future enhancements to improve usability for heavy users. Built Voice Notes & Audio Recorder provides a straightforward, account-free solution for capturing and managing quick voice recordings.",
