What is tool overlap?

Tool overlap is paying for two or more AI products that do the same job — for example Copilot and Cursor for the same engineers. It signals consolidation savings without capability loss. Spendassay detects overlap across connectors, prices the cheaper redundant seats of the low-usage pair, and hands admins consolidation steps.

Every figure Spendassay publishes about tool overlap carries a proof level saying how much guessing sits behind it, and opens to show the rows it was computed from. The full method is on the methodology page.
