What is OpenCreator?
OpenCreator, formerly KrillinAI, is a local AI workspace for individuals and teams working on creative and development tasks. Its content tools cover video downloading and translation, subtitle editing, voiceovers, image and video generation, article writing, short-video scripts, and stick figure animation. Creation templates provide reusable prompts and settings, while revisions preserve earlier configurations and outputs.
The application uses Codex CLI as its agent execution engine. Visual controls and agent conversations share workflow state, including progress, settings, versions, and results. Desktop installers are documented for Windows and macOS, with Codex CLI included; the browser interface runs from source against a local runtime. Project data, attachments, and logs remain local by default, while model availability depends on configured services, credentials, account access, and the operating environment.
The project is released under the Apache 2.0 license. It brings visual settings, reusable Skills and agents together for scripts, video, images, voice, translation and editing in a single workspace, and the repository states that OpenCreator was formerly known as KrillinAI.

Key capabilities
- Video localization Transcribe media, translate subtitles, configure bilingual output and dubbing, and export subtitles, audio, or rendered video.
- Subtitle editing Adjust timing against a playback-linked waveform and timeline, split or merge cues, replace text, and preview subtitle styles.
- Media generation Generate images, thumbnails, videos, and voiceovers using configured AI services, with reference inputs and model-specific settings.
- Writing and animation Produce editable articles, social posts, segmented short-video scripts, and narrated stick figure animations.
- Agent workflows Organize project conversations, background runs, approvals, schedules, memory, local Codex Skills, and MCP configuration.
- Revision history Create separate versions for changes and regeneration while retaining previous settings and outputs.
Where OpenCreator fits
OpenCreator fits workflows that combine video localization, voiceover production, generated media, and written content. A creator can import media, refine subtitles visually, generate dubbing, and export a rendered result, or use agent conversations and reusable Skills to coordinate production stages.
Before deployment, teams should verify model credentials, provider access, language coverage for transcription and dubbing, and platform-specific service availability. Some video sources require cookies and availability varies by video and region. Source-based web use requires Node.js, pnpm, and an available Codex CLI. Backups must cover both the OpenCreator runtime data and the separate Codex configuration and session directories.
