Tap a word. Understand it. Keep reading. ClickBook is an ebook reader with an AI that lives inside the app. Tap any word you do not know and it explains it right there on the page, without leaving your book and without looking anything up. Because the AI runs on your phone, it works anywhere — on a plane, on the underground, in a country where your data plan does not. There is no account to create, no email to hand over, and no subscription. WHAT HAPPENS WHEN YOU TAP A WORD • Meaning — a short, plain definition in the language of the book • Example — the word used in fresh sentences, so it actually sticks • Translation — the word explained in your own language (Pro) • Context — the sentence around it explained in your own language (Pro) • Ask ChatGPT — open the word and its passage in ChatGPT when you want to go further (Pro) FOR READING IN A LANGUAGE YOU ARE STILL LEARNING Choose your mother tongue when you set the app up, and explanations come back in it. You can read a novel slightly above your level without a dictionary in your other hand, and without breaking the thread of the story every few minutes. Every word you look up is saved to your vocabulary list, with the sentence you found it in. PRIVACY, THE REAL KIND The AI model ships inside the app. It is not a wrapper around a chatbot in a data centre, so your books and the words you look up stay on your device. Turn on airplane mode and the reader and every explanation still work — that is the test, and it passes. The one exception is Ask ChatGPT (Pro), which sends a word and its passage to ChatGPT only when you tap it, and asks you first. No account. No sign-up. No tracking. No ads. FREE, AND WHAT PRO ADDS Free gives you the whole reader, your library, offline AI explanations of what a word means, examples that use it, and your vocabulary list. ClickBook Pro is a single one-time purchase — not a subscription — and adds translation into your own language, context translation of the whole sentence, the Ask ChatGPT button, changing your mother tongue whenever you like, and control over the order the answers appear in. YOUR BOOKS Open EPUB files from anywhere on your device or from iCloud Drive. PDFs are converted when you import them. Three classics are included so you have something to read the moment you open the app. Four fonts, adjustable text size and line spacing, white, sepia, mint and dark pages, and page-by-page or continuous scrolling, because a reader you cannot read comfortably is not much of a reader.

Verdict
The clearest difference is update cadence: ClickBook at every 4 days against Mythos Reader's every 2 weeks. On price, ads, in-app purchases and device support there is nothing between them.
