Your skill library, living in your menu bar.
Hotkey palette
Open your library from the keyboard and insert prompts and skills into any app.
Agent Destinations
The Mac app materializes every skill as a real skill folder — SKILL.md plus attachments — in ~/.claude/skills and your Codex setup. Local edits sync back as new versions.
Versioning + readiness
Version every change, attach reference files and scripts, and let the built-in AI optimizer turn rough notes into agent-ready skills — with a readiness score that tells you when a skill is good enough for agents to use on their own.
Mac-native updates
Sparkle auto-updates keep Prompttly current, and the app is notarized by Apple.
