Hi there! We're John Clark and Trevor Huey. After nearly 20 years of trying to keep our own documentation up-to-date we built a tool to help us. Meet Hyaline!

For us the biggest pain point was keeping track of what documentation needed to be updated for each PR we landed, especially when our documentation was spread out across multiple repositories and documentation sites (both internal and customer facing). So we built Hyaline to extract documentation from any source and then identify which pieces of documentation should be updated. Hyaline uses an LLM to examine the contents of each pull request and then comments on the pull request with any recommended documentation updates it finds.

We also added an audit tool to run checks and an MCP server to make your documentation even more useful.

Instructions to quickly try out Hyaline are available here (1), or you can visit the website to read more about what Hyaline does and how it works.

Thanks!
