You ship AI features. Then the bill arrives.

Most teams have no idea where their AI spend is going until it's too late.

Your OpenAI bill is $800.

You have no idea which feature caused it. You start guessing.

One user is making 500 requests a day.

You find out a month later when accounting asks questions.

You switched to Claude Haiku to save money.

Did it actually work? You have no way to measure it.

How it works

import { AISpendTracker } from '@ai-spend/tracker'
const tracker = new AISpendTracker({ apiKey: 'ast_xxxx' })
 
// drop-in replacement — nothing else changes
