Write about your day, a decision you're weighing, or a memory that resurfaced, and Compaxi automatically organizes everything into a personal knowledge graph of people, places, and experiences, finding connections across your entire history. No new format to learn. Just talk to Compaxi the way you'd talk to a good friend. Share what happened, what you're thinking about, or what you're trying to figure out. Every conversation becomes part of your personal memory graph. Connections you didn't see coming: That coffee chat last Tuesday and a career decision from two years ago? They're linked. Compaxi finds second, third, and fourth-order connections across everything you've ever written, patterns you'd never spot in a traditional journal. Ask your past. Plan your future. "What led to my best decisions?" "Who have I lost touch with?" "What was I feeling the last time I faced something like this?" Ask real questions and get answers drawn from your own experiences, not generic advice. Your knowledge graph, visualized: See your memories as an interactive graph. Events, people, and places appear as nodes. The connections between them reveal the hidden structure of your life: the recurring themes, the people who shaped your thinking, the places where breakthroughs happened. Jumpstart with what you already: Import photos from your library and Compaxi extracts the memories behind them, or connect your Instagram or bring in conversations from other AI assistants to build your graph faster. Private by design: No ads. No data sales. Ever. Features • Conversational journaling powered by AI • Personal knowledge graph connecting people, places, and events • Semantic search across your entire history • Photo import with automatic memory extraction • Instagram and AI data import • Interactive graph visualization • Daily journaling nudges and follow-up reminders

knibl is an notetaking and knowledge mapping app that turns scattered ideas into a connected knowledge graph. Built for writers, worldbuilders, researchers, students, and creative thinkers, knibl helps you capture notes, extract entities, visualize relationships, and organize complex projects in one place. Automated extractions and AI-augmented processes trivialize the monotony of other notetaking systems to give you more time for writing. Whether you are drafting a novel, building lore, planning a campaign, or structuring deep research, knibl is designed to help you think in connections instead of isolated documents. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ - AI note extraction and entity mapping: Import raw text or any common text format, then let knibl identify key concepts, people, places, and relationships to automatically build a visual story graph you can explore, edit, and expand. - Cross-device sync: Automatically keep notes and graph data synced so you can capture ideas and continue deep on any device without interruption. - Security-first architecture: Workspace content is encrypted at rest with AES-256-GCM, and core account/API protections are designed to support reliable, privacy-conscious creative work. - Share links for notes, folders, and workspaces: Generate viewable links when you want to present specific content to collaborators, readers, or stakeholders without exposing your full private environment. - Backlinks and relationship-first navigation: Jump from any note to related notes fast, reinforce bidirectional context, and keep important references discoverable as your workspace grows. - AI Workspace chat with graph-aware context: Ask questions about your workspace, request summaries, trace how entities connect, and get context-aware answers grounded in your notes and graph structure. - Daily journal and streaks: Capture day-by-day progress in a dedicated journal workflow, then revisit entries over time to track momentum, ideas, blockers, and creative development. - Graph analytics and progress insights: Track nodes, links, files, and weekly activity with built-in dashboard views that help you measure output and keep long-form projects moving.
