There are many note-taking apps ranging from Apple Notes and Google Keep to Obsidian and Notion. Most of them use text as the primary input method and provide features around it. Developer Louis Pereira’s Audio Pen app focuses on converting your voice to neat text-based notes.

Audio Pen is a web app, so don’t expect a native mobile experience. But this means it’s pretty lightweight and available across platforms. The interface is barebone. You can tap or click on the mic button to start recording. Once you hit the stop button, the app transcribes the audio using OpenAI’s APIs — namely Whisper for transcription — and converts them into clean text.
