BigMarc f5faa27f88 GrammaGem — open-source, on-device macOS writing assistant
Native SwiftUI menu-bar app: global hotkey → capture selected text (AX API /
clipboard fallback) → grammar (Harper) / local AI (MLX) → replace in place.
Free/paid entitlement gate + Lemon Squeezy device-cap licensing, $0 marginal
cost per user. Heavyweight engines behind protocol stubs so it builds out of the box.
