Ghost Pepper is a macOS hold-to-talk dictation app that runs entirely on-device using Apple's WhisperKit for speech recognition and LLM.swift for smart cleanup. You hold the Control key to record, release to transcribe, and the transcribed text is automatically pasted into whatever app you're using. No cloud, no subscription, no data ever leaves your Mac. The "smart cleanup" feature is what sets it apart from basic Whisper wrappers: it uses a local language model to remove filler words, fix self-corrections in real time, and clean up stutters without altering your intent. Version 2.0.1, released April 6, brings improved accuracy and lower latency on Apple Silicon. It requires macOS 14+ and an Apple Silicon chip. Ghost Pepper hit the top of Hacker News' Show HN section on April 7 with 354 points and 164 comments — an unusually strong signal for a solo-dev open-source tool. The timing is notable: as commercial dictation tools like Wispr Flow move to paid-only models, Ghost Pepper offers a fully free, auditable alternative. It's MIT-licensed and available on GitHub.

Suno generates complete songs — vocals, instruments, arrangement — from text descriptions. V5 added real instrument rendering, multi-track editing, and stem separation. Used by creators for content music, jingles, and experimentation.
Reviewer scorecard
“This is the dictation tool I've been waiting for. On-device, zero latency once warmed up, MIT license, and the LLM cleanup actually works. I replaced Wispr Flow with this in under 5 minutes. The Control-hold UX is more ergonomic than I expected.”
“Apple Silicon only and macOS 14+ means a significant portion of Mac users are locked out. The 'smart cleanup' LLM adds another model to memory — not ideal if you're already running other local models. Also, no GUI means non-technical users won't touch it.”
“V5 crossed the quality threshold. Previous versions sounded AI-generated. This one sounds like a band recorded it. Whether that's good for the music industry is another question.”
“Ghost Pepper is a preview of how computing will feel in 5 years: ambient voice input everywhere, zero latency, zero cloud dependency. The fact that a solo dev shipped this in Swift using WhisperKit and LLM.swift is a testament to how capable the Apple Neural Engine stack has become.”
“Suno is doing to music what Midjourney did to images — making creation accessible to everyone. The cultural implications are massive. We'll see AI-human collaborative albums within a year.”
“I tried it during a writing session and the filler-word removal alone is worth it — my raw dictation comes out cleaner than when I type. The hold-to-talk model also means I'm never accidentally recording. Solid privacy story for journaling and creative work.”
“For content creators who need background music, jingles, or intro tracks, this eliminates a $200-500 expense per project. The quality is production-ready for digital content.”
