Echologue: A Private Voice Journal You Can Ask Later Most journals are great for capture and terrible for retrieval. Echologue turns raw voice notes and daily entries into a structured memory you can actually ask about later. CAPTURE Use voice when typing is too much friction. Record what happened, who was there, how it felt, and the small thoughts you don't want to lose. Echologue handles the structuring. ASK YOUR HISTORY Entries become retrievable memory instead of dead text. Ask about a person, trip, mood, or time period and get an answer grounded entirely in what you actually recorded: * "What were the highlights of my trip in Barcelona?" * "How do I usually feel around this person?" * "What small insights keep coming back?" FACTS + FEELINGS Echologue separates objective facts from your emotional states, extracts people and themes, and indexes entries. By keeping what happened and how you felt distinct, your recall stays trustworthy instead of vague. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 100% LOCAL-FIRST PRIVACY Your personal archive shouldn't be a cloud database. * On-Device Storage: Your journal history, semantic memory, and profiles live exclusively on your device's local database. * Zero-Retention AI: When AI helps structure an entry or answer a question, the processing is strictly ephemeral. Data is sent securely for processing and deleted immediately. It is never logged or used for training. Total Portability: You own your data. Export to JSON/CSV, or wipe your archive completely at any time. No account required.
