naruhoro is a Chrome extension designed to enhance communication during Google Meet sessions by allowing users to insert audio and stamp reactions with a single button click. It comes preloaded with four default reactions: "なるほど" (I see), "へぇ～" (Oh really), "うんうん" (Uh-huh), and "えぇ" (Yes). Users can also customize their reactions by uploading their own audio files in MP3 format and PNG images for stamps, making video calls more engaging and personalized.

This tool includes a dedicated mute button that allows users to silence their microphone while still sending audio reactions, ensuring that background noise does not interfere with the meeting. The extension was developed to address the challenges of presenting materials while sharing screens, where feedback from participants can often be lacking. By simplifying the process of providing verbal cues, naruhoro aims to create a more interactive and supportive environment during online presentations.
