AI-Powered Reading Companion
Find what matters in any
Upload any document and instantly find the parts that actually matter to you. Skip the fluff, dive into what sparks your curiosity.
Start with what's relevant to you.
You bought the book. You want to learn. But 300 pages feels impossible when only 20 pages actually matter to you right now.
Time drain
Hours spent reading chapters that aren't relevant to what you actually want to learn.
Lost interest
Your excitement fades before you reach the good parts. The book joins the unfinished pile.
ADHD brain
Your mind craves the interesting stuff. Linear reading fights against how your brain naturally works.
Read smarter, not harder
ArcRider uses AI to understand meaning, not just keywords. Tell it what you're curious about and it finds exactly those sections.
Semantic search
Search with keywords, themes, emotions, or abstract concepts. The AI understands meaning, so you'll find relevant sections even when the exact words don't appear.
Page-level precision
Get exact page numbers. Open your book, flip to that page, and start reading what matters.
AI summaries
Get quick summaries of the relevant sections so you know if it's worth diving deeper.
Zero guilt
Finally, permission to skip what doesn't serve you. Read books your way.
Built for ADHD brains
We get it. Your brain wants to hyperfocus on the interesting parts, not trudge through 50 pages of setup. ArcRider lets you follow your curiosity instead of fighting it.
