Lore App

Lore is a self-hosted, open-source archive designed for private storage and search of AI conversation exports. It addresses the need for users to keep their Claude, ChatGPT, Gemini, Le Chat, and DeepSeek conversation histories securely on their own server, with no reliance on external accounts or subscriptions. The platform emphasizes user privacy and data ownership, ensuring that all conversations remain fully encrypted and under the user’s control.

Security is central to Lore’s design. All encryption and key derivation occur client-side within the browser, using AES-256-GCM encryption and PBKDF2-SHA256 with 310,000 iterations. The encryption key, generated from the user’s password, never leaves the device, and only ciphertext is stored on the server. A master key is wrapped and stored, remaining inaccessible without the password. Brute-force protection features include rate limiting, progressive delays, and IP-level lockouts, all configurable in the app’s settings. An emergency kit is generated at registration, providing a printable recovery key for password resets without data loss. Logout procedures wipe all sensitive data from the device, including clearing IndexedDB and removing the master key from memory. Email is optional and used solely for account-level reset notifications, allowing users to maintain full anonymity if desired.

Lore is installed by uploading its files to any PHP 8+ shared hosting environment with MySQL, requiring no Docker, Node.js, Composer, or build steps. Users configure the app via a simple config file, create a database, and import the provided schema. The web-based interface is mobile responsive, offering dark and light modes, full-screen animations, and navigation optimized for phones. Conversation ZIP exports from supported AI platforms are imported and processed entirely in the browser, ensuring raw data never reaches the server unencrypted. Search functionality is implemented locally, with decrypted conversations cached in IndexedDB for fast, round-trip-free queries. Users can export their archives as plaintext JSON or re-encrypted ZIP files, keeping their data portable.

Released under the MIT License, Lore is free to use, with no telemetry, analytics, or tracking. It is intended for individuals seeking a private, encrypted, and searchable archive of their AI conversations, prioritizing user control and data sovereignty.
