FAQs
Frequently asked questions.
What is Kit and how does it use AI?
Kit is an email marketing platform creators run their business on. We've focused on making Kit connect well with the AI tools you already use rather than building AI into every corner of the product.
Do I have to use AI to use Kit?
Not at all. Kit is built for creators first. AI is available where it's useful and completely out of the way where it isn't.
What AI tools can I connect to Kit?
You can use the Kit MCP to connect to Claude, Cursor, ChatGPT and more to manage your Kit account with an AI assistant. You can also connect to other AI-powered apps through the Kit App Store to add specific capabilities to your workflow.
What's the difference between Kit MCP and the Kit App Store?
Kit App Store apps add AI capabilities inside Kit, like turning a YouTube video into a newsletter that's added directly to your account. Kit MCP connects your existing AI client to your Kit account so you can work from your AI tool directly. They solve different problems and work well together.
Where do I start if I'm new to using AI with Kit?
The subject line generator is already available in the broadcast editor. If you want to go deeper, the Kit App Store is a good next step. If you're already using an AI client like Claude or Cursor, Kit MCP is worth exploring.
How do I use AI to write better emails?
Kit has a built-in AI subject line generator that suggests and tests subject lines tailored to your content. You can also install AI-powered apps from the Kit App Store—like Lex—for drafting, editing, and refining your emails before you send.
Is there a cost to using AI features with Kit?
Kit App Store apps vary. Some are free, some require a subscription. Kit MCP is free to connect to any of the AI tools you're already using.
I'm a developer. Can I use AI to build on Kit's API?
Yes, the Kit Developer Docs MCP connects your AI client to Kit's full API documentation, so you can ask questions and get answers grounded in the actual docs. It's a faster way to build without constant tab switching.
