What is the best software for Annex IV technical documentation?

By a count, not a judgement. For each requirement named above the table, a tool scores 1 where its own site states it, a half where it states part of it and 0 where the pages we read say nothing. Complipath is scored by the same rule from its own pages, so it is first only where the count puts it first.

It is written by Complipath, so read it as ours. What keeps it checkable is that every cell for another tool is that tool's own sentence, linked to the page it stood on with the day it was read, and every Complipath cell is our own page. Open the side-by-side page for any tool to see all fifty rows.

That none of the pages of that tool's site we read said it. It is a statement about those pages and not about the product. It counts zero in the ranking. Ask the vendor before you rule anything out, and check the date on the table, because sites change.

A price is printed as the vendor's own words only while our reading of it is recent. When the reading grows old, the cell turns into a link to their pricing page instead of a quote, so this page never shows a figure the vendor may have changed since we read it.
