Introducing Mark — a $129 AI bookmark that helps book readers remember everything. 🧵👇 Thread:

The world holds centuries of brilliance—Einstein’s physics, Nietzsche’s philosophy, Jobs’ innovation. Visionaries spend lifetimes refining ideas, making breakthroughs, and distilling their wisdom into books. Yet instead of tapping into this gift, most people are stuck in the endless scroll. Imagine the next innovations that could happen if we all engaged with knowledge instead of fleeting content.

Attention is fragmented, and books—one of the greatest tools for intellectual growth—are underutilized. Reading shouldn’t be this hard to engage with.

We don’t blame you—reading is broken. For decades, big tech has pushed eBooks and Kindles as the future of reading. Yet 65% of Americans still prefer physical books—the feel, the experience, the deep focus. But print lacks what digital tools provide: engagement, accessibility, and efficiency. Readers want to get lost in books and absorb knowledge—not just passively consume words.

Mark is the key to this shift. We’re not just a product—we’re an ecosystem designed to make reading engaging and impactful. Crafted from Grade 5 titanium and inspired by Bauhaus design, Mark seamlessly fits into your pages—a statement of elegance and status.

With Mark, you read your physical book as usual. When you are done, you slip your Mark bookmark in as usual. But this time, something changes. Immediately synced to your devices to view on the go you have access to:

1. Summaries of the exact pages you just read. Even with deep reading and careful note-taking, we often struggle to recall key ideas just days later. Mark generates personalized summaries tailored to you— whether you prefer key themes, powerful quotes, or quick stats. Mark uses spaced repetition to break the forgetting curve, delivering smart reminders to revisit your notes so knowledge actually sticks.

2. A Connected Reading Community Mark transforms reading into a shared experience—allowing you to exchange insights, discuss ideas, and learn alongside friends and family. Just like Strava keeps you motivated in fitness, Mark keeps you inspired in reading.

3. Personalized Data & Tracking Understand your reading data- track your reading pace, topic growth, and intellectual progress over time. See how you’re improving, refine your habits, and optimize what you read next. At the end of the year, Mark Wrapped gives you a personalized recap of everything you’ve learned.
