Input
Parse the request rows
The auditor accepts JSON arrays, records arrays, or NDJSON from common gateway exports.
AI Cost Attribution Auditor
Paste one trace and see which team, service, and model caused the spend.
Paste a trace or invoice row
Use JSON, a records array, or NDJSON with cost, model, and owner fields. Nothing is uploaded.
Public one-off analysis runs locally in this browser tab.
Paste a trace to start
Results stay empty until you run analysis on pasted JSON or NDJSON with cost plus model, team, tenant, project, or customer fields.
Analyze and Clear are disabled until input is present.
Need recurring reviewed reports?
One-off analysis is public. Saved history, shared reports, and monthly review are handled through early access.
From pasted trace to spend owner
Use this page when the bill moved and you need a first owner-level answer before starting an integration.
Attribution
Group spend by owner
Team, tenant, customer, project, service, and model fields become the attribution table.
Next step
Carry the result forward
Copy or download the derived table, then join the waitlist when recurring reports matter.
Why this tool
AI spend is invisible across teams. Engineering sees the bill go up, Finance can't tell which tenant or workload caused it, and chargebacks stall because no one trusts the numbers. This free auditor turns a raw gateway-trace export into the cost-attribution evidence both sides agree on — no vendor demo, no pilot, no data leaving your browser.
How it works
- 1
Paste a JSON or NDJSON gateway trace from OpenAI, Anthropic, Bedrock, LiteLLM, or your in-house proxy.
- 2
See the cost broken down by team, tenant, and model — with an explicit unattributed bucket.
- 3
Export attribution as JSON / CSV to attach to the chargeback ticket or RCA.
Benefits
Team-level cost visibility across tenants and models.
Chargeback-ready CSV / JSON export — drop straight into the Finance ticket.
Detects outlier consumption with a ≥50% concentration flag.
Works with OpenAI, Anthropic, AWS Bedrock, LiteLLM, Helicone, OpenRouter, and homegrown gateway logs.
No data stored — every parse runs in your browser tab, nothing uploaded.
