Frequently Asked Questions

SentiaRead is an intelligent reading companion built for English learners. "Sentia" comes from Latin, meaning "to perceive." Our AI combines dual perception: it perceives text context to give precise definitions, and perceives your proficiency level to explain in terms you understand. With AI-powered contextual definitions, cross-device sync, and unified content management, you can absorb English naturally. It is ideal for students, avid English enthusiasts, and professionals who read English material regularly.

Download the app on macOS, iOS (iPhone & iPad), or Android, create an account, and start importing your EPUB ebooks. We offer a free version so you can experience AI contextual definitions and visual memory reinforcement. Upgrade to Plus to unlock cloud sync, full podcast transcripts, unlimited storage, unlimited translations, and more.

SentiaRead currently supports EPUB, PDF, TXT, and Markdown files, as well as podcasts and YouTube video transcription. You can also import content from web pages or paste directly from your clipboard. All imported content works with AI contextual definitions and visual memory reinforcement. Podcasts also feature sentence-synced transcripts, highlighting, notes, and instant translation.

Files: use Import in the library, or on a computer drag an EPUB, PDF, TXT or Markdown file onto the window. On phones and E-Ink readers, open the file from your file manager and choose SentiaRead. Web articles: paste the link into the import field, or use Share in your browser and pick SentiaRead. On a computer, install the Chrome extension and save the article from the page itself. Pages behind a login or paywall usually cannot be read this way. Text: copy anything, choose Import from clipboard in the library, and paste. It is saved as a clipping. Pasting a link only saves the link as text, it does not fetch the page. Whatever you import on one device is readable on the others as soon as you sign in with the same account.

Highlight any word or phrase and the AI coach instantly generates the most relevant explanation based on the surrounding text. You can tailor the difficulty (A1-C2 CEFR level) or even stay fully in English for immersive practice. For example: • Traditional dictionary: "run" has 20+ definitions, leaving you to guess which applies • SentiaRead: In "The program runs smoothly," "run" means "to execute or operate" (explained with B1-level vocabulary if that is your setting) This is i+1 comprehensible input: every explanation sits comfortably within your reach.

Yes. When a sentence slows you down, tap Reading Assist and SentiaRead rewrites it into a simpler version that keeps the original meaning. It is a faithful restatement, not a summary, so nothing is dropped. The rewrite follows the i+1 comprehensible input principle: the simplified sentence stays just within your reach instead of pushing you somewhere harder.

When you add a word to the "Learning" list, it is highlighted automatically across everything you read afterwards. Seeing it in multiple authentic contexts reinforces recall far better than rote memorization.

SentiaRead is available on macOS, Windows, iOS (iPhone & iPad), Android, and as a browser extension for Chrome. Android E-Ink reading devices are also fully supported. All platforms share the same core features: AI contextual definitions, visual memory reinforcement, and cloud sync.

Your progress, highlights, and vocabulary lists sync automatically across all your devices via secure cloud sync. Every change follows you instantly. Pick up right where you left off on any device. All data is encrypted for security.

No. Kindle is a closed system that does not run Android apps. For reading with SentiaRead, we recommend open Android devices like Onyx Boox.

Free is a complete reader on its own: library, reading and notes are all there, plus a weekly allowance of AI credits for in-context lookups and explanations. AI is not locked behind Plus. Plus removes the credit ceiling. Lookups, translation, AI explanations and short-text generation become unlimited under fair use, and you also get cloud sync across devices, multimedia ingestion (transcription and text-to-speech), 120 minutes of high-quality read-aloud voice per month, advanced notes and priority support.
