eisonAI Read less linearly. Think more deliberately. Most writing is organized around how ideas were written, not how they are best understood. Paragraphs follow the author’s discovery order. Key assumptions appear late. Important transitions go unmarked. As a reader, your effort shifts: from judging ideas → to staying oriented. eisonAI is designed to fix that structural problem. -------- What eisonAI does eisonAI helps you see structure while you read, without rewriting the original text or replacing your judgment. It works directly on real-world content — long articles, essays, research notes — and makes the moments where meaning actually forms structurally visible. -------- Cognitive Index™ Structure, not summary Instead of summarizing or rewriting, eisonAI highlights the parts of a text where: - decisions are made - assumptions are introduced - arguments turn You can scan ideas at a glance, then choose where to slow down and think. Reading stays yours. Understanding becomes deliberate. -------- Designed for long-form reading - Handle long documents (up to 15,000 tokens) - No need to pre-segment or manually clean content - Stable performance on real, messy texts eisonAI is built for actual reading, not demo examples. -------- Works where you already read - Safari Extension: see structure directly on the page - No copy-paste workflows - No context switching Reading happens where it always has — eisonAI works alongside it. -------- Local-first by design - On-device processing - Privacy-first architecture - Sensitive content stays private Your reading data remains under your control. -------- Library & organization - Save what matters - Tag and revisit ideas - Build a personal reading library that reflects how you think, not just what you saved -------- CloudKit sync - Keep your library in sync across devices via iCloud - Seamless continuity between iPhone, iPad, and Mac -------- Open source, auditable Trust code, not promises. Core components are open source and inspectable. -------- No subscriptions One-time lifetime access. Restore anytime. -------- Who eisonAI is for - Readers who think while they read - Writers who care about argument structure - Researchers working with long texts - Anyone tired of “AI summaries” that think for them -------- Who it’s not for - If you want instant summaries without thinking - If you want AI to replace your judgment eisonAI does not decide for you. It reveals structure so you can.
