The signature difference is Q&A Primer: before you read, AI poses 3–5 questions to prime you, then you self-grade afterwards. It is learning-science-backed retrieval practice that lifts day-30 retention from 22% to 64%. No other mobile reader does it.

Free users can generate 3 summaries a day across all four modes (TL;DR, Key Insights, Q&A Primer, Action Items). Upgrade to Pro for unlimited reading and the full Q&A Primer with a retention dashboard.

Follow-up answers cite the exact source paragraphs they relied on — tap a citation to jump back and highlight it. You can always verify against the source instead of trusting blindly. Always check important details against the original.

No tracking, no ads, never sold. Article content is sent to our self-hosted AI gateway only to generate the summaries and Q&A you request — never for advertising or model training. See the Privacy Policy for details.

Manage or cancel in iOS Settings → Apple ID → Subscriptions. Cancellation takes effect at the end of the current period; Pro stays usable until then.

In the app, go to Settings → Delete Account. This permanently and irreversibly removes your account and all associated data — profile, saved articles, summaries, Q&A, highlights, and primers.

v1.0 is iOS 17+ with an English & Chinese interface and paragraph-level EN→zh-Hans translation for English articles. EPUB/PDF import and a browser extension are on the roadmap.
