USDThe problem
AI spend spirals fast — and silently.
How one unmonitored setting becomes a number nobody saw coming.
A founder's monthly Claude bill after a setting was left on
A fintech employee's AI bill in a single week
Burned by teams with no usage limit set
By the time the invoice lands, the spend is already done. CosTruss shows you the meter running — in real time.
Illustrative scenarios, not customer data. The shape of the problem is the point.
The solution
Visibility before costs get out of control.
CosTruss gives you a single, real-time view of every dollar flowing to your AI providers — so you can act in hours, not weeks.
See it live
Hourly syncs keep spend, tokens, and trends current across every provider.
Understand the drivers
Break cost down by model and provider to find exactly what's burning budget.
Act before it compounds
Budgets and 80% / 100% alerts turn a surprise invoice into a non-event.
How it works
Three steps to controlled AI spend.
Connect
Link your OpenAI or Anthropic account with your own credentials. Keys stay encrypted and never touch the browser.
Monitor
CosTruss syncs your usage every hour, breaking down tokens and cost by model and provider.
Control
Set monthly budgets and get alerted at 80% and 100% — before a spike becomes an invoice shock.

Cost Dashboard
Every provider reports cost in its own shape. CosTruss normalises them into one dashboard: spend by provider, by model, and by day or month, next to the token usage behind it. Where a provider publishes no token counts for a model, the field reads Not reported instead of a misleading zero.
- Spend by provider, model, and time period in one view
- Daily and monthly trends with date filters
- Token usage shown honestly, or marked Not reported
- Hourly sync, so the meter is never far behind

Cost Groups
Know Which Product Is Costing You More.
Organize AI spending by products and supported provider resources. See where costs accumulate, configure group budget alerts, and keep unassigned spending visible.

Automatic discovery
CosTruss lists the resources a provider exposes: OpenAI projects and API keys, Anthropic workspaces.
Manual setup
Add resources and type IDs by hand whenever a provider cannot be listed, or when you would rather map them yourself.
Discovery finds resources, but you confirm what they belong to. A project name rarely matches a product name, so nothing is attributed until you map it — and cost that stays unmapped shows up under Unassigned rather than disappearing.
Checkout assistant
83% of budgetProvider-reported cost for exactly these resources.
Unassigned
$37.20Provider cost with no product mapped to it. Counted once, in the organization total only.
Demo preview with sample figures. Your own products, resources, and budgets appear here once a provider is connected.
Organization
Your AI Spend. One Organization-Wide View.
Monitor spending across your connected AI providers and access provider setup and resource-mapping workflows from one place.
OpenAI and Anthropic each show their connection state, last sync time, and how many resources were discovered, so a provider that needs attention says so here instead of failing quietly.
