Frequently asked questions
Can ChatGPT make videos?
Not natively inside the chat. OpenAI's video model runs in Sora, a separate app with its own plan. Connecting Krater puts video generation directly in the conversation, alongside images, voice and documents.
Is this an official ChatGPT app?
Krater connects through ChatGPT's custom app flow, the standard way to add MCP tools. It works inside ChatGPT but is built and run by Krater, not OpenAI.
What does it cost?
Nothing extra beyond your Krater plan. Krater MCP is included in Ultra and Max, and requests use the same plan credits as inside Krater.
Do I need developer mode?
Yes, for now: adding a custom app in ChatGPT requires enabling Developer mode in Settings > Apps. It is a one-minute toggle, not coding.
Can I disconnect it later?
Yes. Remove it from Settings > Apps in ChatGPT, or revoke access in Krater under Settings > API keys.
