Google-verified security assessment — most apps never get this

Before

OpenAI charges your card directly. Anthropic sends a PDF invoice to a shared inbox nobody monitors. Vercel bills your GitHub org under a separate email. Railway deducts from a prepaid balance you forgot existed.

You discover the damage 30 days later when the statement arrives and someone has to reverse-engineer a spreadsheet to figure out which engineer left a testing loop running for three weeks.

After

Per-model cost breakdown for OpenAI and Anthropic — usage mapped to your projects and time windows, not just a monthly total from a PDF invoice.

Automated anomaly detection flags when a model's usage spikes overnight, so you intervene before a junior engineer's eval script becomes a $5,000 mistake.

subscriptions.

Forgotten trials and idle services cost real money every month. Prism scans your inbox, calculates the run-rate, and flags anything that looks like waste — so you can cancel before the next renewal. See how it compares to tracking this manually.

02 / API costs

Per-model AI costs,
down to the token.

An OpenAI invoice is just a total. Prism pulls from usage endpoints and shows cost by model, time window, and project — so when the bill jumps, you know exactly what moved. Read our guide to tracking API costs.

You shouldn't discover a runaway script on the monthly statement. Prism automatically flags when 24-hour spend exceeds 3× your 7-day average and pings your Slack channel before the damage compounds.
