Sentely is a simple app for collecting sentences and learning vocabulary through real context. It uses offline AI—a small on-device language model—to help you learn words in context. Save sentences you find interesting or useful, including through OCR capture, organize them into your personal library, and turn them into daily study material. By learning words within real sentences, you can build a deeper understanding of how language is actually used. Sentely goes beyond passive reading with an active learning loop: (Optional: Save a sentence) → Mask a word → Guess → Check the answer → Review AI suggestions To help you learn beyond simply checking the answer, Sentely is powered by a small on-device masked language model. It suggests context-appropriate alternative words and expressions directly on your device—no network connection, no server processing, and no reliance on a huge LLM. Features: - AI-powered word suggestions (small on-device language model) Example: "She [. ] the book on the table." → put / placed / left - Mask-and-guess practice for active recall - All data stays on your device Additional features: - Collect and organize sentences (OCR supported) - Build your own personal sentence library - Turn saved sentences into daily study material Sentely is designed for learners who want to build language skills step by step, using real sentences as the foundation.
