Most notes apps are just storage. You write something, it disappears into a list, and you never think about it again. Wisen works differently — it reads what you write and brings the right ideas back at the right moment. Echo finds threads across your notes and turns them into questions worth sitting with. Not generic prompts — specific questions built from what you actually wrote. Sometimes it connects two notes from different weeks and surfaces a pattern you hadn't noticed. Each session feels less like a review and more like continuing a conversation you forgot you started. Pulse delivers a daily brief built entirely from your recent notes. What you've been thinking about, what's still unresolved, what questions are worth returning to. It also drafts LinkedIn posts, emails, and more directly from your notes — your voice, your ideas, not a generic AI output. WisenChat lets you ask anything about your notes. What did you write about this topic last month? What's still unresolved? What decisions are you avoiding? It answers from your actual notes with citations — so you always know where the insight came from. Knowledge Map shows how your notes connect visually. Tap a link to open a cross-note Echo session between two related ideas. The map grows richer the more you write. Spaced repetition tracks which ideas you've genuinely learned and which ones need revisiting — at the block level, using a modified SM-2 algorithm. Mastered content is excluded automatically so you're never drilling what you already know. Everything is encrypted with AES-256-GCM before leaving your phone. AI features use OpenAI — only the content you actively engage with is ever processed, and none of your notes are used to train their models. Import PDFs, scan handwritten notes, drop in images and voice recordings. Works in 16 languages. No account required to start. The longer you use Wisen, the more useful it becomes. Your notes compound into real knowledge instead of disappearing. ## Key features - AI-powered idea surfacing - Daily note digests - AI chat for note queries - Visual knowledge mapping - Spaced repetition learning - PDF, image, and voice import ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/wisen-ai-notes-and-knowledge/id6760642726/reviews.md ### 3/5 — Crash *2026-07-13* Ios26.4.1 ## Frequently asked questions about Wisen ### What is Wisen?
