OpenCreator (formerly KrillinAI) is a multimodal creative workspace designed for local execution, integrating visual creator tools, reusable Skills, and AI Agents. Built with a React-based frontend and a Fastify-powered local daemon, the platform leverages the Codex CLI as its primary execution engine rather than reimplementing the Agent loop. This architecture allows for a synchronized dual-mode workflow where a shared state machine maintains consistency between the visual workspace and natural language Agent conversations. The system features ten current creator tools, including video translation (utilizing Whisper for transcription and LLMs for segmentation), video downloading via yt-dlp, image generation, and stick figure animation. Technical capabilities include managed runtime components for automatic yt-dlp updates, a versioning system that preserves previous iterations of creative outputs, and support for Model Context Protocol (MCP). Developers can extend the platform through custom Skills defined in SKILL.md. The software is available via a web implementation or a dedicated Electron-based desktop app, which provides native OS capabilities like directory selection and tray behavior while maintaining the same core runtime and data via a shared local SQLite database.
