Sui-IB/InternalBeyond

What it solves

Internal Beyond (IB) is a single-file, offline-first personal website project designed to maintain emotional continuity with AI. It provides a highly customizable, private environment where users can interact with multiple AI models as companions, managing all data locally in the browser's IndexedDB without relying on a network server.

How it works

The project is a pure frontend application (HTML/JS) that users open directly in a browser. It connects to AI services via API keys (supporting Claude, GPT, DeepSeek, Gemini, and custom endpoints). It features a comprehensive suite of modules that integrate AI into various life-management and entertainment functions, including a pixel-art interactive room, a social feed, a calendar, and a a long-term memory system.

Who it’s for

Users seeking a private, aesthetically pleasing AI companion experience that combines productivity tools (code workspace, calendar, blog) with emotional interaction and roleplay (interactive stories, tarot, voice/video calls).

Highlights

• Comprehensive AI Integration: Supports up to 10 independent API endpoints, each with custom nicknames, relationships, and system prompts.
• Emotional Memory System: A long-term memory library with star-map visualization, natural decay, and "Auto Memory" where AI can autonomously create and update memories.
• Multimodal Interaction: Includes real-time voice and video calls with speech-to-text, text-to-speech, and acoustic mood references, as well as an AI-driven code workspace (ICode) with sandboxed Python/JS execution.
• Local-First Privacy: All user data, including chat histories and logs, is stored locally in the browser, with one-click JSON export/import for backups.
• Rich Feature Set: Features a pixel-art interactive room (Room), a shared social circle (Circle), an AI-readable calendar, and a specialized cinema DLC for watching videos with AI.
• Dual Visual Themes: "Internal" (light/day) and "Infernal" (dark/night) themes with smooth crossfade transitions.
