AudioPen

Overview

AudioPen is an AI voice note tool that turns spoken thoughts into clean, structured text in a style you choose. You record a voice note, and AudioPen transcribes it using Whisper, then rewrites the transcript with a second AI pass that removes filler words, organizes the ideas, and formats everything as a LinkedIn post, email, article, meeting summary, or any custom style you define. The tool is designed for people who think faster than they type, want to capture ideas hands-free, or struggle to get from raw thoughts to shareable output. It was built by solo indie founder Louis Pereira and has grown to over 200,000 users. AudioPen uses one-time payment plans with no auto-renewal, which distinguishes it from subscription-first competitors. Free accounts get 3-minute recordings and 10 stored notes. Paid plans unlock 15-minute recordings, unlimited storage, audio file uploads, SuperSummaries, Zapier integrations, and custom writing styles that match your personal voice.

Best For

Writers and content creators who dictate drafts and want clean text without heavy editing, Professionals who capture ideas during commutes, walks, or meetings and need structured notes waiting when they arrive, Freelancers and consultants who brain-dump client meeting highlights and want a polished summary, Non-native English speakers who think in another language and want grammatically clean English output, Anyone who prefers speaking to typing and wants AI to handle the formatting

How It Works

Open AudioPen in your browser, iOS app, Android app, or Chrome extension and hit record. Speak naturally, ramble, go on tangents, or change direction mid-thought. AudioPen processes the audio in 20-60 seconds using Whisper for transcription and a second AI rewrite pass. Before or after recording, you select a writing style (formal, casual, bullet points, LinkedIn post, email, and more) and output length. The rewritten text is ready to copy, share, or export. Prime users can combine multiple notes on the same topic into a SuperSummary for research projects. Existing audio files can be uploaded for transcription and rewriting without recording live. Zapier and webhook integrations allow notes to be automatically pushed to Notion, Gmail, Slack, or other tools in your workflow.
