Read-only keys, never your prompts

Every dollar your AI spends, in one ledger.

Ratelytics reads usage straight from your providers, converts it at the daily rate, and joins it to Stripe revenue, so you can see which customers cost more than they pay.

Free forever on one provider. 7-day trials on Starter and Growth, card up front, cancel in two clicks.

Your AI spend is scattered across six consoles and none of them talk to your revenue.

Each provider bills in its own currency on its own schedule. Seat tools bill once a month. Nothing tells you what a single customer actually costs. So the number in the board pack is a guess.

1Spend arrives late. You find out a job ran away when the invoice lands, not while it is running.
2Cost is not attributed. Total spend is easy. Spend per customer, per key, per model is the part nobody has.
3Waste goes unnoticed. Retries, uncached prefixes and frontier models doing trivial work all bill at full price.

Product

Four screens, one question each

No dashboards to assemble. Every screen answers something a founder actually asks.

Ledger

Every provider and subscription in one place, converted at the daily rate. Seat tools are amortised daily so nothing spikes on a renewal date.

Total spend · last 30 days£4,182.77
Customers

Stripe revenue joined to AI cost, per customer. Loss-making accounts sort to the top, because those are the ones you need to price differently.

Meridian Logistics−£63.40 · −42.6%
Autopsy

A forensic read of 90 days of usage. Findings ranked by confidence, every formula shown, every figure traceable to its evidence table.

Savings found£818.93 /mo
Alerts

Budgets per workspace, provider, key or tag on any provider, and — where usage is reported by the hour — an anomaly rule stated as a plain sentence. Email and Slack, both on Growth.

Connectors

Connect the providers you already pay

32 providers: 15 live provider and gateway APIs, 11 by CSV preset, 5 flat-fee tools amortised as subscriptions, and Llama through whichever host serves it. Plus Stripe for revenue and a generic CSV importer for anything not named here.

Stripe

Revenue, synced nightly. This is what turns cost into margin per customer.

CSV import

Any billing export up to 3.5MB. Columns auto-match, and re-importing the same file adds nothing twice.

Subscriptions

Cursor, ChatGPT Team, Claude Max and the rest. No usage API, so we amortise the monthly value daily.

Provider APIs are polled hourly. Spend routed through a gateway is attributed to the gateway only, never counted twice.Request a connector

Autopsy

We show the formula, so you can argue with it.

Every finding names the keys and models it looked at, states its arithmetic in full, and opens onto the evidence table it was computed from. Low-confidence reads are flagged for review and claim no saving at all.

Questions we get asked first

What kind of key do you need?

A read-only or usage-scoped key, and nothing more. We never ask for a key that can send requests, and we never read the content of your prompts or completions. Revoke it at the provider whenever you like; the history we have already read stays.

How quickly do figures appear?

The first rows land within about a minute, then history backfills behind them. After that we poll hourly, so figures can trail the provider's own console by up to an hour.

What if a tool has no usage API?

Add it as a subscription and we amortise the monthly value into the ledger daily, so your daily figures stay comparable. If the tool runs on your own provider key, it already shows up under that provider; adding it twice would double-count it.

Can I look around before connecting anything?

Yes. Every account opens with two seeded, read-only demo workspaces so you can read a full ledger, a customer margin table and a finished autopsy before you paste a key.

Find out what your AI actually costs you

One read-only key is enough to start. The ledger opens the moment the first rows land.
