Overlap is a question, not a cancellation command

Two tools sharing the same job can still both earn their place. One may be a specialist, one may be embedded in an important workflow, or one may act as a deliberate backup. The useful question is whether each subscription has a distinct reason to stay.

AI tool overlap calculator FAQ

Does feature overlap mean I should cancel a tool?

No. Shared jobs are a review signal. They do not prove that one tool is redundant.

How does the overlap calculator work?

You assign jobs to each tool. The calculator compares those labels and shows every pair that shares at least one job.

Does StackDiet guess what a tool can do?

No. This calculator only compares the jobs you assign. It does not invent product capabilities.

Can I add jobs that are not in the preset list?

Yes. Add custom jobs separated by commas. Matching custom labels are treated as overlap.

Where is my overlap data stored?

Your entries are stored locally in your browser so you can return to them on the same device. No account is required.
