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
