It Looks Fine. That's the Problem.
You open the document and glance through it. Headings are clear, the chart makes sense, nothing's out of place. To you, it reads fine.
The hard part isn't spotting what's wrong. It's translating what you see into something a screen reader can actually parse, and most tools make that harder than it needs to be. Buried menus. Settings with no clear effect. No way to tell if your fix actually worked.
Shpruce works differently. Point at a heading, a chart, an image, and tag it for what it is. What you already know about your document becomes real structure, without digging through menus or second-guessing whether anything changed.
