Splitleaf is the CMS for the AI era, on your device. It is a Mac app with a visual website builder, a CMS and an AI agent workspace. The agent reads your website, your product docs, reviews competitors and your search data. It proposes new pages and posts, and it writes the drafts. You review each change and publish. There are no monthly fees, no lock-in and no limits. 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. Our founder built and maintained websites for 50+ businesses. After launch, 9 of 10 fell behind the business. The blocker was never the CMS, it was content. 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. - Nothing goes live without you. You see each change and publish only the changes you select. - Your website stays yours. It is HTML, CSS and Markdown files in your own GitHub repository, on the host you choose. How it works 1. Link the folders that describe your business: product docs, release notes, brand files. 2. Select Generate idea. The agent reads your website, your folders, competitor blogs and your Search Console data. 3. Tick the ideas you want. Each idea gets a plan, search terms and sources. 4. The agent writes the drafts. You edit them on a visual canvas. 5. Review the changes and publish. Why on your device Your business context is already on your computer. Splitleaf reads it where it is. You do not upload your files to us. The agent uses your own key from Anthropic, OpenAI or OpenRouter, at the provider's price. AI models will soon run on your computer too. Splitleaf is ready for them. Who it is for - Freelancers and web agencies that keep many client websites current - Startups and software companies with a marketing website to grow - Founders and marketers who need new content without a developer Pricing Try every feature free. A one-time license costs $129 and covers unlimited websites. Teams start at $6 a month for each collaborator. Splitleaf charges nothing for hosting or AI. Availability Splitleaf is available for Mac.
