Mapping hundreds of old URLs to new ones by eye is the slowest part of a migration. Let the tool draft the map, then review only the weak matches.
The example below is already loaded, so you can see exactly what you get. Replace it with your own list and the result updates as you type.

In a site migration the slow part is working out which new page each old page should redirect to. Put the old URLs in the editor and the new URLs in the second list: each old URL is compared with every new one by the words in their paths (ignoring years, file extensions and filler words), and the closest match is written next to it with a similarity score.
Anything below the minimum score is marked as “no match” instead of guessing, so you can review those by hand. The output is in “old | new | score” form, which Build Redirect Rules turns straight into 301s.
