AI Tool Overlap Calculator
Enter what you pay for AI writing, chatbot, coding, and image tools - and, if you're also paying for a second tool doing any of the same job, enter that too. See exactly how much of your AI stack is likely duplicate spend.
Example: a stack with one overlap
A $39/mo writing tool plus a $20/mo second writing tool, a $20/mo chatbot subscription with no overlap, and a $10/mo coding assistant with no overlap adds up to $89/month total, with $20/month ($240/year) of that being likely redundant spend across 1 overlapping job category. Enter your own numbers above to see your real overlap.
Methodology
For each job (writing/content, general chatbot, coding assistant, image/design), we compare the cost of your main tool against a second tool you enter for that same job. When both are non-zero, the smaller of the two is counted as redundant monthly spend - a conservative floor, since a single tool already covers that job. Redundant amounts are summed across all four jobs and annualized by multiplying by twelve.
Data source: none - totals are computed entirely from the costs you enter. Last reviewed: September 2026.

Frequently asked questions
How does this decide what's "redundant"?
For any job where you enter costs for two AI tools, we take the smaller of the two as a conservative estimate of what's provably unnecessary - since one tool already does that job, at minimum the cheaper of the two is spend you could cut without losing any capability.
Why would I be paying for two AI tools that do the same job?
It happens gradually rather than on purpose - a chatbot subscription for general questions, a separate writing tool for content, a coding assistant bundled into your IDE, and an image tool for graphics all get added at different times, and most of them can partially do each other's job too. Few people sit down and audit the overlap at once.
Why the smaller amount, not the bigger one?
We don't know which tool you'd actually keep - that depends on quality, integrations, and habit specific to your workflow. Using the smaller figure keeps the estimate conservative rather than assuming you'd cut your main, likely more capable tool.
I only use one AI tool per job - why fill this out at all?
If you have no overlap, this calculator will show $0 redundant spend, which is itself a useful, honest result - it confirms your AI stack isn't carrying duplicate subscriptions, rather than manufacturing a savings number that isn't real.
