Transkribeer is a free, open-source Mac app for audio transcription. Choose between OpenAI (GPT-4o/Whisper), Google Gemini, or free local Whisper — or run all three at once to compare results side by side. Drag & drop any audio file. Long recordings auto-split and reassemble seamlessly. FFmpeg downloads automatically — zero setup needed. Supports mp3, m4a, wav, ogg, flac and more. No subscription, no vendor lock-in. Pay only for cloud API usage or use the completely free local mode.
