Read like it’s a book again. One touch for anything else.
An Android reader for TXT, EPUB, and PDF. Long-press a passage to look it up, ask about it, or turn it into an image. Page turns timed to Fibonacci ratios so they feel like a real book. Claude 4.6, GPT 5.5, Gemini 3, and Grok 4.3 on tap. Up and running with a small group while we polish. Reach out and we’ll get you in.
What we do
ThinkPack works in three directions. One is shipping today. Two are running quietly with a small group.
The Studio
AI help for local services, websites, and customer-facing teams. Friendly, plain English, no buzzwords. The first conversation is always free.
Start a conversation →Reader
A quiet Android reader for TXT, EPUB, and PDF. A real page, no scroll, warm reading themes, and an AI you can dial in or turn off. Up and running with a small group while we polish.
Request access →Discord
Multi-model AI for your server. Claude 4.6, GPT 5.5, Gemini 3, and Grok 4.3 working together. Live in a few servers right now. If you’d like in, say hi.
Request access →Inside the Reader
Built around the page, not the scroll. Long-press any passage to look it up, ask about it, or turn it into an image, all without leaving where you are. Frontier models on tap when you want them, and quiet when you don’t.
A real page
Tap or swipe to turn. Nothing scrolls anywhere. Page-turn animations follow Fibonacci timing so they feel natural instead of canned.
One-touch lookup
Long-press any passage and ask. The AI reads with you — it knows the page, the surrounding pages, and an evolving summary of the book — so the answer fits the story.
One-touch image
PROSend a passage to image generation and get an illustration of the scene right there in the book. Saved to a per-book Gallery.
Top-of-the-line models
Claude 4.6, GPT 5.5, Gemini 3, and Grok 4.3 are all available. Pick what fits, dial how chatty it is, or turn it off entirely.
Easy on the eyes
Light, Sepia, Dark, High Contrast, and Fractal themes. Warm ink-on-cream by default.
Your books, your phone
TXT, EPUB, PDF. Local library. No account required.
Free classics built in
Thousands of public-domain books from Project Gutenberg, in the Discover tab.
Quiet by default
No ads, no streaks, no nudges. The reading is the experience. The AI is there when you reach for it.
Most reading apps borrow from feed apps. Endless scroll, push notifications, blue on white. We went the other way. A fixed page, warm colors, page turns timed to Fibonacci ratios so they feel like a real book turning, and an AI that gives you a sentence when you ask, not an essay you didn’t.
My wife and I use it every night. Library lives on your phone. AI runs through our backend, no third-party keys in the app. The free tier is enough on its own.
Already shipped: work-memory on PyPI. A local-first development memory layer for VS Code and MCP clients.
