YakWareReference Search Manager indexes large regulatory and safety reference documents — such as the OSHA standards and the USACE EM 385-1-1 safety manual — and lets you search them in plain language instead of by exact keyword. You ask a question, and it returns the relevant passages along with the section they came from, so you can confirm the source.
It is aimed at safety professionals and field staff who need to find a specific requirement quickly rather than paging through hundreds of pages. Additional reference manuals can be added to the index over time.
