Drop in a long video. tondi transcribes it on your Mac, finds the moments worth clipping, burns in word-timed captions and exports clips in the shapes you choose (9:16, 1:1, 4:5, 16:9) as ordinary MP4 files. Nothing is uploaded, there is no queue, and nothing is metered: a 20-minute video and a 3-hour recording cost the same. Free with no end date, 3 clips per video. Pro is $10 a month or $100 a year. Apple Silicon Macs, macOS 13 or later. Signed and notarized by Apple.

Could you build this?
Partial Building an on-device Mac app that manages local Whisper speech-to-text, LLM semantic chunking, and FFmpeg/AVFoundation video rendering pipeline requires native desktop systems programming.
What it would actually take: A production version would be built using Swift/macOS or Electron with native C++ bindings, bundling whisper.cpp (or Apple Silicon CoreML Whisper) for transcription and a local quantized LLM for clip discovery. The challenging piece is building a hardware-accelerated video processing pipeline (via Metal or AVFoundation/FFmpeg) that handles word-level timed subtitle burning, aspect-ratio reframing, and smooth multi-stream rendering completely on-device.
