AyahLab

AyahLab is a dedicated desktop Quran-study application positioned as free, offline, and privacy-first. Its official site describes a broad toolkit that includes per-word morphology annotations, manuscript viewing through Corpus Coranicum sources, recitation audio with ayah-synchronized highlighting, word-by-word meanings, notes and bookmarks, rich-text editing, and scientific computing workflows. The project explicitly states that it has no accounts, no telemetry, and no analytics, with user data stored locally, and it presents the app as available across Windows, macOS, and Linux with only limited network use for optional manuscript images and downloaded recitation audio.
