I built this because I was frustrated with how hard local AI transcription tools are for non-technical users. Whisper gives amazing results, but most solutions require knowledge of Python, Docker, CLI, or uploading files to the cloud. I wanted something truly plug & play. This runs fully locally, uses OpenAI Whisper, and works directly inside Aegisub — install → transcribe → edit subtitles. It’s especially useful for: - YouTubers & creators (SEO, captions, Shorts) - Privacy-sensitive workflows - Non-English languages You can use it for free for short clips (up to 60s), which covers YouTube Shorts, TikTok and Reels. There’s also a free 7-day trial with no limitations. Happy to answer questions, and I’d love feedback from people using Whisper today.
