Seven capabilities
One reading studio.
From a premium reader to spaced repetition — every capability in Glaux is designed to compound. What you learn in one session becomes the foundation for the next.
Premium Reader
Typography worthy of the words.
Read anything beautifully. Traditional, Focus, and Pace modes in one distraction-free studio.
Glaux's reader is built for the experience of the text, not feature density. Choose your mode, customize your typography, and read without the clutter of a general-purpose reading app. The studio adapts to you.
- ◎Traditional mode — natural scroll, elegant type, your pace
- ◎Focus mode — comprehension-friendly chunks for dense material
- ◎Pace mode — word-by-word guided highlighting to train speed
- ◎Customizable font, size, line height, and margins
- ◎EPUB, PDF, articles, and web URLs

Ask Glaux
Cited to the passage. Verifiable in one tap.
Ask anything about what you're reading. Every answer is grounded in the text and cites its source.
Most AI gives you a confident-sounding answer that floats free of your source. Ask Glaux works differently: every response points back to the specific passage it drew from. You can verify it in one tap — or jump straight to the context in the book.
- ◎Natural-language questions about anything you're reading
- ◎Answers grounded in your actual text, not a general knowledge base
- ◎Every response cites its source passage
- ◎Tap the citation to jump to the text in context
- ◎Works across books, PDFs, articles, and URLs

AI Summaries
Grounded in what you actually read.
Turn a chapter or session into structured key ideas, vocabulary, and recall prompts.
Summaries in Glaux are built from the specific text you read — not a generic dataset. Each summary organizes what you covered into key ideas, vocabulary you encountered, and prompts to help you recall it later.
- ◎Generated from your reading session or a specific chapter
- ◎Structured into key ideas, vocabulary, and recall prompts
- ◎Grounded in the passages you actually read
- ◎Saved to your session notes for reference
- ◎Premium: unlimited summaries per day

Vocabulary
Words you encounter become words you own.
Tap any word for a clean definition, save it, and build mastery over time.
Vocabulary in Glaux is tied to the context you encountered the word in — not a flashcard deck you built from scratch. Saved words appear in your vocabulary list and can feed directly into your Memory Deck.
- ◎Tap any word for an instant clean definition
- ◎Save words with one tap — no context lost
- ◎View saved words in your personal vocabulary list
- ◎Saved words can become Memory Deck cards
- ◎Reinforced through spaced repetition in your deck

Not trivia. Questions grounded in the text you just read.
Generate comprehension quizzes from what you read to test — and cement — understanding.
Glaux quizzes are generated from the passages you just read, so they test your comprehension — not your ability to recall general trivia. Missed answers feed directly into your Memory Deck so the gaps close automatically.
- ◎Generated from your session or a specific chapter
- ◎Questions tied to the text — never generic
- ◎Multiple choice and short-answer formats
- ◎Missed answers automatically seed your Memory Deck
- ◎Premium: unlimited quizzes per day

Memory Deck
SM-2 algorithm. Like Anki, built into your reader.
Insights become spaced-repetition cards, so what you learn actually sticks.
The Memory Deck is Glaux's spaced-repetition engine — similar to Anki, but built directly into your reading workflow. Cards are created automatically from highlights and quiz misses, and surfaced at the optimal time for recall. The more you use it, the smarter it gets.
- ◎SM-2 spaced-repetition algorithm — proven science
- ◎Cards auto-created from highlights and quiz misses
- ◎Home-screen widget for daily review without opening the app
- ◎Performance tracking shows your recall improving over time
- ◎Full Memory Deck available on Premium

Learning Insights
A Reading Fitness curve that proves you're improving.
Track reading progress, focus, recall, and your growing body of knowledge.
Learning Insights gives you a clear view of your reading habit: how much you've read, how well you recall it, your vocabulary growth, and a Reading Fitness score that compounds over time. It's not just a reading log — it's a knowledge ledger.
- ◎Reading Fitness score based on actual recall performance
- ◎Session history — books read, pages covered, time spent
- ◎Vocabulary growth over time
- ◎Memory Deck performance and retention trends
- ◎Quiz accuracy history per book and overall
