Percivo helps you understand nonfiction books through your own goals, mindset, and life situation. Not generic book summaries. Personalized book insights that show what each idea means for you. Explore the same book through different lenses, including Entrepreneur, Parent, Student, Coach, Creative, and Busy Professional. Start with Core Insights, the real DNA of the book. Real book analysis, not a retelling. Then open the same book through a different lens: the way an Entrepreneur reads it. The way a Coach reads it. The way a Parent, a Creative, or a Student reads it. Same book - Completely different insight. This is not a summary app. This is a perspective engine for serious self improvement. ONE BOOK. MULTIPLE DIMENSIONS. Every book in Percivo unlocks multiple lenses so the ideas land where they matter: - The Entrepreneur: Decisions, leverage, scalable thinking, and execution. - The Busy Professional: Priorities, career clarity, and sharper work. - The Coach: Behavior change, mindset shifts, and helping others grow. - The Creative: Original thinking, expression, and idea generation. - The Student: Structure, retention, and faster understanding. - The Parent: Relationships, family dynamics, and emotional intelligence. WHAT'S INSIDE PERCIVO - 2,800+ nonfiction books, decoded with real book analysis. - Multiple perspectives per book, not just the gist. - 4 - 8 minutes per insight. Real depth, real speed. - Daily picks built around your personal development goals, not an algorithm. - The Vault to save your most important takeaways. - Highlights Tab to capture every line worth keeping. - Business, psychology, habits, productivity, finance, creativity, and more. WHY IT FEELS DIFFERENT Most learning apps treat every reader the same. A founder and a parent need completely different things from the same book. Percivo is the first book insights app built around that truth. A reading app where book analysis is tailored to your life. Not a summary. More like a prism. Open Percivo. Pick your lens. See your next book differently. —————————————————— SUBSCRIPTION & LEGAL INFORMATION —————————————————— - Percivo Premium is available as an auto-renewable subscription with weekly, monthly, or annual plans (a free trial may be included), or as a one-time Lifetime purchase. - If a free trial is offered, it will automatically convert to a paid subscription unless canceled at least 24 hours before the trial ends. - Payment will be charged to your Apple ID at confirmation of purchase (or at the end of the free trial, if applicable). - Subscription renews automatically unless canceled at least 24 hours before the end of the current period. - You can manage or cancel your subscription in your App Store account settings after purchase. - Privacy Policy: https://percivo.app/privacy - Terms of Use: https://percivo.app/terms

About

Anti/Agent

Features

Save is not the same as learn. A chat answers and forgets. Anti/Agent is the opposite: every page you build comes back and teaches you, on the day you'd otherwise forget. It's an AI notebook for both knowledge and skills. Drop in sources, write your thinking, and choose how each page should return. HOW A PAGE IS BUILT - Sources: drop anything in. URLs, PDFs, YouTube, audio, past pages. Read, indexed, ready to cite. - Editor: a real editor, not a chat. Blocks, formatting, drag-to-reorder, a slash menu. - AI partner: highlight, ask, and the AI streams a researched, cited section right into the page. THREE WAYS A PAGE TEACHES YOU BACK - Memory: flashcards in your own words. You type the answer in plain English and the AI grades it like a teacher. Spaced repetition (FSRS) books the next review for the day your memory is about to slip. - Thinking: dialogues that talk back. Debate a claim, rehearse a mock interview, hold a conversation in a new language, or explain an idea to a curious learner. Each session comes back a little harder. - Skill: exercises with your own rubric. You set the standard in the page; the agent grades your attempt against your bar, not generic correctness. WHY IT STICKS Recognizing an answer and producing it from memory are different skills. Anti/Agent removes the gap between writing something down and being asked about it later, so understanding a source and remembering it stop being two separate jobs. SHARE AND LEARN TOGETHER Make a page public when you're proud of it. Start your own from a page somebody else shared. Spaced repetition keeps pulling either of you back. LEARN ANYTHING Screenwriting. Japanese, French, Mandarin. Python, Rust, ML. Philosophy. Music theory. Anything you can write a page about. FREE TO START 100 credits every month, no card required. Unlimited pages and every learning block on the free plan. PRIVATE BY DEFAULT Your content is never used to train AI models, never shared with third parties, and stored on encrypted infrastructure. Delete everything any time. GO FURTHER WITH A SUBSCRIPTION Optional auto-renewable subscriptions unlock more monthly credits: Starter ($9.99/month) and Pro ($24.99/month). Prices may vary by region.
