Mythos
The AI Reading Assistant
Built for Students
Dense textbooks, unfamiliar jargon, reading in a second language. Mythos Reader is the AI book reader for students that turns any hard passage into an instant summary, explanation, or translation, right inside the page. Free on iPhone and iPad.
Free tier included. No trial timer.
In classical mechanics, the principle of least action states that the path taken between two points by a physical system is the one for which the integral of the Lagrangian over time is stationary, meaning small perturbations of the path leave the action unchanged to first order.
Reading for school shouldn't grind you to a halt.
The three places textbooks lose you, and what Mythos Reader does about each.
A paragraph you've read four times and still can't parse. Highlight it and Mythos Reader rewrites it in plain language at the level you want, without you leaving the page or typing a prompt.
Terms the textbook assumes you already know. One tap on the word or phrase gives you a quick definition in context, no side quest into a dozen browser tabs.
Coursework in English when it isn't your first language, or a required source in French, Spanish, or Japanese. Mythos Reader translates any passage inline in dozens of languages.
From textbook to understanding,
in three taps.
The AI reader for students is built around one loop: upload, highlight, understand. Repeat through a whole chapter without breaking your reading flow.
Upload your textbook
Drop in any EPUB or PDF. Course readers, assigned chapters, or scanned handouts sit next to your novels in one library.
Highlight what you don't get
Tap and drag on a term, a sentence, or a whole paragraph. Mythos Reader detects what kind of help you're asking for and suggests the right action.
Read the explanation, keep reading the book
A plain-language explanation, a chapter summary, or a translation appears inline. Close it and the textbook picks up exactly where you were.
Built for how students
actually read.
The AI book reader for students combines the four moves you already make when a textbook loses you. Mythos Reader makes each one a single tap.
Summarize a chapter before lecture
Select a chapter, a section, or a few paragraphs. Mythos Reader gives you the core argument and supporting points so you walk into class primed, not lost.
Explain jargon in plain language
Legal prose, scientific notation, unfamiliar frameworks. Highlight the dense part and get a clear rewrite that actually teaches, not a generic paraphrase.
Translate passages inline
Reading English coursework as a non-native speaker, or a French or Japanese source for a course. Mythos Reader translates on the spot, without leaving the page. This is the single most-cited feature in our App Store reviews.
Ask anything about the passage
Type a follow-up question about exactly what you highlighted. No prompt engineering, no pasting context into ChatGPT, no losing your place in the book.
Free for every student.
No trial timer.

Student FAQ
What is Mythos?
Mythos is an AI-powered book reader for iPhone and iPad. It lets you select any text in an EPUB or PDF and instantly get contextual AI actions like summaries, explanations, translations, and character lookups, all without typing anything.
Is Mythos free?
Yes. Mythos is free to download with daily AI actions included.
What platforms is Mythos available on?
Mythos is available on iPhone and iPad via the Apple App Store.
Can I import textbooks and course readers as PDFs?
Yes. Mythos Reader reads both EPUB and PDF. Drop in an assigned chapter, a course reader, a scanned textbook, or a lecture handout from Files, iCloud, Google Drive, or Dropbox. Every AI action (summarize, explain, translate, ask) works the same way on a PDF as on an EPUB, so you can use one reader for the whole semester's material.
Can Mythos Reader help me read textbooks in a language I'm still learning?
Yes. Inline translation is one of the most-praised features in our App Store reviews, and non-native English readers are consistently our top reviewers. Keep the textbook in its original language, highlight any passage, and Mythos Reader translates it on the spot. If a translated sentence still feels dense, ask for a plain-language explanation as a follow-up. The same flow works in reverse if you're reading a French, Spanish, or Japanese source in English.
Is using Mythos Reader considered academic dishonesty?
Using Mythos Reader to understand an assigned reading is no different from looking a word up in a dictionary or asking a TA to walk through a paragraph. It helps you comprehend the text your course expects you to engage with. Using AI to write an assignment that you then submit as your own work is a separate question, and that falls under your school's policy. Mythos Reader is built for the reading side of studying, not to draft your papers for you.
Do I need a .edu email or a student account to sign up?
No. Mythos Reader is a single product with one account type for every reader. Sign up with any email and the free tier is identical for students, professionals, and everyone else. There's no verification process, no student-only plan to apply for, and no school affiliation required.

Loved by students and
non-native English readers.
Two groups show up most often in our App Store reviews. We build for them.
Non-native English students reading assigned coursework write about inline translation as the thing that made Mythos Reader stick. They keep the textbook in English, highlight passages they'd otherwise have to paste into Google Translate, and stay inside the book while they study.
Native English students tackling dense material, philosophy, law, medicine, physics, write about the summarize and explain actions keeping them on task instead of bouncing to ChatGPT every paragraph. The through-line: AI tools for studying textbooks work best when they live inside the textbook itself.
