Splitleaf is the CMS for the AI era, on your device. It is a desktop app for Mac and Windows, with a visual website builder and agentic CMS.
AI builds a website in one evening. The content still takes weeks. A normal CMS does not help, because it waits for someone to hand it finished content. We have built and maintained websites for 50+ businesses. After launch, 9 of 10 fell behind the business. The blocker was never the CMS. It was the content.
Splitleaf allows your business to connect the AI provider you already use to your website project, it reads your website, the folders you give it acces to, competitor blogs and your search data. Then it proposes new pages and posts, and it writes the drafts with the goal of generating organic traffic that lasts.
What you get
- Your website changes when your business changes. A new product or a new release becomes a new page.
- You never start from a blank page. Splitleaf proposes ideas from your product docs, release notes, competitor blogs and Google Search Console data.
- Each idea shows its sources. You can check every claim before you write.
- You pick an idea. The agent writes the draft in the voice of your website.
- The agent does the site work too. Ask it to add a language, translate a page, change the site settings or duplicate a page.
- When you move a page, a folder or a collection, the links to it on your pages and in your components change too.
- Nothing goes live without you. You see each change as it will look, compared to the live site. You publish only the changes you select, to a staging site or straight to live.
- Your website stays yours. It is HTML, CSS and Markdown files in your own GitHub repository, on the host you choose. The site folder holds only your site and one settings file.
Why on your device
Your business context is already on your computer. Splitleaf reads it where it is. Any folder works, including the folders that Google Drive, OneDrive and Dropbox sync to. You do not need to sign in to them, and you do not upload your files to us. The agent uses your own key from Anthropic, OpenAI or OpenRouter, at the provider's price. It also works with your Claude Code sign-in, and the usage counts against your Claude plan. AI models will soon run on your computer too. Splitleaf is ready for them.
