Show HN: Crisper – On-device voice to polished text for macOS
speakcrisper.com
I built Crisper because every dictation tool I tried either sent audio to the cloud or gave me raw, messy transcripts I still had to fix.
Crisper runs entirely on-device — no network calls, no account, no subscription. It does two things in sequence: transcribes using a speech model, then runs a local LM pass to strip filler words, fix grammar, and make the output sound intentional. The whole thing takes ~1–2 seconds on Apple Silicon.
A floating hotkey pill sits above every window. When you're done recording, it auto-pastes back into whatever app you were in before — Slack, Notion, VS Code, anything.
A few things I'm happy with: - Three recording modes (toggle, hold-to-record, re-paste last) — all rebindable - Full transcript library with source app, timestamp, and audio playback - Fully offline after first-run model download
Free to download. Would love feedback on the AI polish quality especially — that's the part I'm still tuning.
