text2mic is a Chrome add-on that enables users to send and receive text and files through microphone audio. The unique feature of this tool is its ability to operate without server processing, ensuring a secure and offline experience. This makes it particularly useful in environments where internet access is restricted or unavailable.

The process is straightforward: users select a file to send, which is then transmitted as binary data through the microphone. Once the transmission is complete, the recipient can download the file, having converted the audio back into its original format. This method allows for practical file sharing in various settings, maintaining both security and convenience.
