SplitJoin is an AI-powered tool that can split and join text or code files based on specific patterns or rules. It allows users to quickly and easily manipulate large files, making it useful for developers, writers, and anyone working with large amounts of text or code.

SplitJoin appears to be a freemium tool with a free version and paid plans for additional features or usage limits. However, I could not find specific pricing information on their website.
