Sayline is a native macOS app that brings private, local voice dictation to any text field. Use global hotkeys to replace typing in Gmail, Slack, VS Code, or Notes. It runs entirely on-device (using NVIDIA Parakeet and MLX), so you can fix grammar, translate, or format text instantly without your audio ever leaving your Mac. Stop worrying about cloud privacy. Just SAY the LINE and watch it appear. Pure magic.
Hey Product Hunt! ๐ I built Sayline because I was tired of how awful the default system dictation is, and I didn't want to pay a monthly subscription for cloud tools just to type with my voice. Sayline is a native macOS app that runs 100% locally. It uses NVIDIAโs Parakeet models (on M-series Macs) for transcription and runs Qwen 3.0 via MLX to handle things like grammar correction or formatting. For Intel Mac users, I included local Whisper models, so they are not left behind! :) Because itโs l
Global hotkey dictation into any text field gets tricky at scale on latency and battery, plus edge cases like secure input fields and flaky accessibility focus. Best practice is streaming VAD + partial hypotheses with a small audio ring buffer, aggressive quantization on MLX, and strict redaction plus disablement for password and secure fields. How are you handling per-app permissions and focus capture on macOS, and is speaker diarization or custom vocabulary boosting on the roadmap?
