In their own words
AudioPen
AudioPen turns spoken thoughts into written text by transcribing speech and rewriting it in a style the user chooses. Users can set a low, medium, or high rewrite level, change output length, describe a style, or provide a sample to match. It can produce writing in a different language from the spoken input, and its site lists many supported languages. Voice typing works in text fields in apps such as Gmail, Slack, Notion, and Google Docs. Zapier and webhooks can send saved notes to other apps; Prime MCP provides ChatGPT or Claude read-only access to notes. Its iPhone, Android, Mac, and Windows apps offer on-device offline transcription, but AI rewriting needs an internet connection. The free plan permits recordings up to 3 minutes. Prime plans support recordings up to 15 minutes, with unlimited rewrites and note storage. The service is intended for individual thought: it does not join Zoom calls or label speakers. Voice-note audio is deleted from servers within 48 hours, and voice-typing audio is not saved.
