Reading dense literature can feel isolating. Theo is an AI reading partner that lives in a floating panel beside your book — always ready to explain, discuss, or challenge what you're reading.
Dostoevsky, through Zosima, argues that self-deception creates a cascading failure of perception. When a person lies to themselves:
It's a psychological domino theory — one that anticipates existentialist ideas by almost a century.
No copy-pasting required. Theo automatically sees your current page and understands the full context of what you're looking at.
Struggling with a dense paragraph? Ask Theo to explain it simply, translate a phrase, or break down unfamiliar cultural references.
Discuss character motivations, explore historical context, or debate philosophical arguments — the kind of conversation you wish you could have about every book.
Theo keeps your conversation history per book. Come back days later and pick up right where you left off.
Use Ollama for fully offline conversations, or bring your OpenAI key. Either way, your reading stays between you and Theo.
