Know exactly how much every AI user costs you.

You ship AI features. But do you know which users are quietly bankrupting you? aimeter tracks real token costs per user and per plan, enforces your limits, and shows you whether your pricing is actually profitable.

Two lines of code. Real enforcement. Real numbers.

18 users on Free have already cost you over $20 each this month.

You can't price what you can't measure.

Most founders only discover the problem when the model bill arrives. By then you've already given away months of expensive AI usage for free.

The free tier tax

A handful of power users on your Free plan can cost more in a month than your entire paid base brings in. You have no idea it's happening until the invoice hits.

Blind pricing

You guessed at $10/month Pro. But you don't know if the average Pro user costs you $2 or $22 in AI. Hard to defend your margins.

Fragile homegrown limits

You built a counter in Redis or the database. It drifts. Users bypass it. You spend weekends fighting abuse instead of building the product.

Two calls. Full control.

You keep calling your AI provider directly. aimeter just sits in the middle for limits and truth.

1. Check before you call

Ask aimeter if this user on this plan is allowed to use this feature right now. Get back remaining quota and cost used. Block or upsell instantly.

const limit = await aimeter.checkLimit({ userId, plan: "free", feature: "rewrite" })
2. Track what it actually cost

After the provider responds with token counts, tell aimeter. We calculate the exact dollar cost using current model pricing and store it against the user, plan, and feature.

await aimeter.trackUsage({ ...tokens, plan, feature, model })

Finally answer the questions that matter.

Stop flying blind. Get the exact numbers you need to run a real AI business.

Know the real cost per user

See exactly how much AI each of your users consumes — by plan, by feature, down to the cent.

Enforce plan limits automatically

Block or gracefully degrade requests when free users or heavy users hit their monthly limits. No more surprise bills.

See plan profitability

Compare what users on Free, Pro, or Team actually pay you versus what their AI usage costs. Price with confidence.

Catch expensive users and features early

Get alerts the moment a user approaches their limit, a feature spikes, or your project budget is at risk.

Which of my users are costing the most?
Is my Pro plan actually profitable after AI costs?
Are free users abusing the expensive features?
What happens if I raise limits on the $29 plan?
Which feature should I optimize or put behind a higher tier?

Start knowing what AI is really costing you.

Sign up, create your first project, define your plans, and add two calls to your backend. You'll have real numbers by the end of the day.
