Frequently asked
Does RichTextEditor have collaboration like CKEditor?
Yes - a per-node Yjs CRDT engine ships in the box for real-time co-editing, plus track changes, threaded comments, and revision history. In CKEditor these are premium-tier features; in RichTextEditor they are included in every license.
Can I use my own AI key?
Yes. The AI Toolkit is BYOK: point it at OpenAI, Azure OpenAI, Anthropic, Gemini, Groq, or a local Ollama - per-tenant keys supported via the key-vault abstraction. There is no AI add-on fee.
