Step 1
Connect your API keys
Add your OpenAI and Anthropic admin API keys. We encrypt them with AES-256 and only use them to fetch usage data.

We find billing emails from Vercel, Railway, GitHub, and 20+ other dev tools. No manual entry needed.
Step 3
See your entire stack in one dashboard
API costs and subscription spending, combined. Set budgets, get alerts before you overspend.
Three ways Prism saves you money
AI startups accumulate tools fast. Prism keeps your stack visible so costs don't spiral.
$440
avg. monthly savings
Hunt zombie subscriptions
Forgotten trials and unused services silently drain your budget every month. Prism scans your inbox and flags anything you're still paying for but not using.
Per model
cost visibility
Break down AI API costs
See exactly what each model costs you — GPT-4.1 vs Claude Opus vs Gemini — across every provider. No more guessing which project is burning through tokens.
Real-time
budget monitoring
Alerts before you overspend
Set budget thresholds and get notified the moment you're approaching your limit. Catch spikes in real-time, not when the invoice lands.
Your data stays safe
AES-256 encryption
API keys are encrypted at rest with industry-standard encryption. Your credentials never leave our secure infrastructure.
Read-only access
We only fetch usage and billing data. We can't modify your account, deploy code, or access your API endpoints.
Works with the tools your startup already uses
From AI APIs to cloud platforms to productivity tools — Prism detects invoices from 100+ services automatically.
…and 60+ more tools detected automatically from your inbox
