About

Gloss

Features
Read full description

Gloss turns anything you read into a conversation with its author. Highlight any passage — in a book, a PDF, an article you saved, or your own notes — and a margin note appears, explaining it more deeply in a voice informed by the author's style (or a thoughtful guide when there's no single author). Ask a follow-up and the note answers, staying right beside the text. The AI lives in the margins, never as a chat window — it reads like a thoughtful annotation, beside the text. Read anything: • EPUB books (DRM-free) — your files, Project Gutenberg, Standard Ebooks, author-direct. (Kindle and Apple Books DRM files aren't supported.) • PDFs — papers, manuals, anything you've saved. • Articles — paste a link and Gloss pulls the readable text to annotate. • Your notes — write or paste text and gloss it like a book. • Select text → Gloss, Go deeper, Define, or Ask — the note streams into the margin (a side column on iPad, an anchored card on iPhone). • Distraction-free reading — three themes (light, sepia, dark), adjustable font, size, spacing, and margins. • Your highlights and notes are saved on your device and travel with each document. Reading is free forever. Your first 10 glosses are free; Gloss Unlimited ($5.99/month or $49.99/year) unlocks unlimited notes. Your files stay on your device — only the highlighted passage and a small amount of surrounding text are sent to generate a note. Author "voices" are an AI interpretation, not the real author, and may be inaccurate. Gloss Unlimited is an auto-renewable subscription: $5.99/month or $49.99/year. Payment is charged to your Apple Account at purchase confirmation. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple Account settings.

Verdict

The call

Leafmark and Gloss are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
