The open-source AI workspace & Skills for creators
Bring visual settings, reusable Skills, and Agents together for scripts, video, images, voice, translation, and editing—all in one workspace.
OpenCreator was formerly known as KrillinAI.
Project Overview
OpenCreator is built for individuals and teams who want to keep creative and development work running locally. Instead of reimplementing an Agent loop, it uses Codex CLI as the execution engine and adds a stable local Runtime, a visual workspace, and a Desktop host around it.
OpenCreator offers two connected ways to work:
- Content workspace: use visual tools and creation templates for video translation and downloading, image and video generation, voiceovers, article and social post writing, short-video scripting, and stick figure animation.
- Agent conversation: start and guide creative or development tasks in natural language, organize conversations by project, keep Runs working in the background, and manage approvals, attachments, files, Skills, MCP, schedules, notifications, memory, and diagnostics from one place.
Web is the single frontend implementation. Desktop loads the same Web build and adds only capabilities that require the operating system, such as directory selection, window lifecycle, tray behavior, and native notifications. With the same data and content viewport, both platforms share the same general UI and Runtime behavior.
Project Highlights
-
🤖 Codex Native: Reuse the Codex Agent loop, models, reasoning, tool calls, conversations, Skills, and MCP without maintaining a second execution engine.
-
🚀 Ready-to-Use Desktop App: Launch OpenCreator directly from the desktop app with Codex CLI included; the local Runtime starts on demand and prepares a default project automatically.
-
⚙️ Desktop Setup That Reuses Codex: On first launch, scan your local Codex configuration and offer to reuse a working ChatGPT sign-in or API key setup. A guided form is available for other model providers.
-
🔄 Managed Runtime Components: Inspect bundled, active, and latest yt-dlp versions, check for updates periodically, and update manually while keeping the current working version available if an update fails.
-
🎨 Multimodal Creation: Create and manage video, images, audio, subtitles, and documents through one connected workflow.
-
🧩 Creation Templates: Start creating images and videos from reusable templates without setting up prompts and settings from scratch.
-
🔗 Dual-Mode Workflow: Work through either the visual workspace or Agent conversation while one shared state machine keeps steps, progress, and results synchronized.
-
🕘 Versioning: Every revision creates a new version while preserving earlier settings and outputs for review and comparison.
-
🧩 Reusable Skills: Use video workflow Skills, extend the Agent with your own Skills, and manage MCP through Codex-native configuration.
-
🧠 Memory: Keep global, project, and thread memory with summaries and reproducible Run input snapshots.
-
🔐 Local Security: Keep data, attachments, and logs local by default, with approvals and redacted diagnostics.
-
🌐 Localized Interface: Use Web and Desktop in 43 interface languages, with automatic system-language detection, manual selection, and right-to-left layouts for Arabic, Persian, Urdu, and Hebrew.
Creator Tools
The current release includes ten creator tools. Available models and services depend on your local Codex environment and AI service settings.
Open the Dashboard to write articles, Xiaohongshu posts, or short-video scripts; create stick figure animations; translate or download videos; generate thumbnails, images, or videos; and create voiceovers with Text to Speech.
More creator tools are continuously being added.
Video Translation offers 123 source languages and 124 target options, including Pinyin output. Search by native name, English name, Chinese name, or language code. Speech recognition and dubbing coverage depend on the selected service and model; the language catalog does not mean every model supports every language.
-
Subtitle-only translation: Import and preview an SRT file, then translate it without a source video, dubbing, or video rendering.
-
Advanced subtitle editing: Open an immersive editor with a playback-linked waveform and timeline, adjust subtitle timing, split or merge cues, and find and replace text. Preview subtitle styles on the video, adjust language, dubbing, and output settings, then generate a new version while retaining earlier results.
-
One-step creation: Configure image generation, video generation, and Text to Speech on one page. Browse models, preview reference images, use model-specific image options, and find voices in a searchable voice library.
-
Multilingual output and progress: Bundled fallback fonts improve complex-script and right-to-left subtitle rendering. Follow transcription, translation, dubbing, and rendering progress with completed and total item counts where available.
