AI Analysis

●●●BangerSlickZero to One

Two-stage local pipeline fixes filler words and grammar better than macOS dictation.

Strengths
  • •Dual-model approach separates transcription from stylistic polishing for better control.
  • •Floating pill interface auto-pastes results directly into the previously active application.
  • •Complete offline processing ensures privacy for sensitive meetings and code discussions.
Weaknesses
  • •macOS-only limitation excludes Windows and Linux users from the workflow.
  • •On-device models may struggle with highly specialized technical jargon compared to cloud APIs.

Post Description

Hey HN,

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.

Macabolic v3.0 – Native macOS video downloader with Menu Bar support

It bundles yt-dlp into a genuinely Mac-first experience — native SwiftUI UI, a Menu Bar–only mode to keep the Dock tidy, and browser extensions for one-click captures. Nothing magical under the hood (yt-dlp still does the heavy lifting), but the app smooths common pain points: easy installs via a DMG or Homebrew tap, presets and preferences, and a friendlier workflow for non-CLI users.
