Find the Right AI
for Your Content.

Upload your real files. Get a professional report showing exactly what each AI provider will cost — per file, per month, at your volume. No tokens. No guesswork. Just the number your budget meeting needs.

AI Providers Quote in Tokens.
You Think in Images and Pages.

You manage thousands of images or documents. Leadership wants to know what AI will cost. So you visit provider websites and find pricing in “tokens per million” — a unit that means nothing to your finance team.

You could ask engineering to build a comparison. They'll need 3-6 weeks, API accounts with every vendor, and a testing framework. Or you could trust a sales rep's estimate — and hope the invoice matches.

Neither option works when your budget review is next week.

CostFunction translates token pricing into the unit you actually manage: cost per file. Upload your real content, pick your providers, and get a professional report with per-file costs, volume projections, and a clear recommendation — in minutes, not weeks.

Upload. Configure.
Compare. Decide.

Four steps from “I have no idea” to “here's the budget line item.”

01

Upload Your Files

Drag and drop the actual images or documents from your workflow. Not stock photos — your real content. Every provider gets the same test, normalized for a true apples-to-apples comparison.

02

Describe Your Use Case

Tell us what you need AI to do: catalog product images, extract data from invoices, describe artwork for accessibility. The report scores each provider against your specific workflow.

03

Set Your Priorities

Cost? Quality? Speed? Rank what matters most and we weight the comparison to match your business goals. Every organization has different trade-offs.

04

Get Your Report

In about 5 minutes, download a comprehensive PDF. Executive summary with a recommendation on page one. Detailed cost-per-file data, volume projections, and full provider comparisons behind it. Ready for a budget proposal or vendor selection memo.

One Report. Every Number
You Need.

Each report is built from your real content, scored against your priorities, and formatted for the people who approve the budget.

Cost Per File

Not cost per token. Not cost per million characters. The actual dollar amount each provider charges to process one of your files. Multiply by your volume and you have a budget number.

Production Readiness Scores

Speed, reliability, content safety, and analysis quality — each provider is scored on the metrics that matter when you move from a pilot to 50,000 files a month.

Images & Documents

Product photos, medical scans, legal contracts, engineering drawings. If your AI needs to see it, we can test it. Same methodology, same apples-to-apples comparison.

Industry-Specific Analysis

DAM cataloging, e-commerce product tagging, insurance claims processing, healthcare imaging. The report evaluates each provider against the task you actually need done.

Volume Projections

See what AI will cost at 1,000 files, 10,000, or 100,000. Know your monthly and annual spend before you sign a contract, not after the first invoice arrives.

Side-by-Side Comparison

Every provider, every metric, on one page. Cost, quality, speed, and safety ratings laid out so your team can compare without flipping between vendor docs.

Full Appendix

Every file, every provider, every response. Descriptions, keywords, thumbnails, response times. The backup documentation that proves you did your homework.
