Free Otter.ai Alternative — No Upload, Unlimited
Free Otter.ai alternative for audio transcription. No 300-minute monthly limit, no cloud uploads. Whisper AI runs privately in your browser.
Otter.ai is a popular AI transcription tool — but it uploads all your audio to their cloud, limits free users to 300 minutes per month, and only stores transcripts in their proprietary app. Our alternative uses Whisper AI running locally in your browser: unlimited minutes, complete privacy, and downloadable TXT/SRT output.

How It Works
Powered by OpenAI's Whisper model running locally via WebAssembly, this tool transcribes spoken audio into text with high accuracy. The AI model loads once and processes your audio entirely on your device — no data is sent to any server.
Upload an audio or video file, select the language (or let it auto-detect), and receive a timestamped transcript. Export as plain text, SRT subtitles, or VTT format for video captioning.
