I kept pasting messages into ChatGPT to sound better. Got annoyed, so I built Rephraser. AI runs 100% on your Mac via Apple MLX. Your text never leaves your device. Select text anywhere — Slack, Gmail, Notion, VS Code — press ⌥⇧R, get a better version in seconds. Works in any app, unlike Apple Intelligence. 9 writing modes · context-aware · diff view · fully offline · free & open source. 🌐 vatsan95.github.io/Rephraser ⭐ github.com/vatsan95/Rephraser
