Product · Ledger

Every AI dollar, attributed to the actor that spent it.

Route AI through Tallin and each request lands in one ledger: attributed to its AI actor (the human, app, or agent that made the call), its owner and team, the provider, model, source, confidence, and coverage state. Give every agent a budget with an automatic cutoff, watch runaway spend freeze before it compounds, and keep the evidence behind every total.

Source-aware cost attribution

See who spent it, where it ran, and how Tallin knows.

Finance systems reconcile what AI cost. Tallin governs the AI activity itself: who or what used it, which model access was allowed, what policy applied, what needs review, and what you can prove. The ledger joins provider, billing, gateway, identity, and expense evidence without flattening their authority. Finance can see the actor behind each dollar and work the rows that still need attribution.

  • Work unresolved spendSeparate directly observed cost from rows that still need attribution.
  • Act before the invoicePair ledger evidence with per-actor caps on routed workloads.
Tallin AI spend ledger showing total spend, directly observed coverage, unresolved cost, provider and actor attribution, evidence source, and attribution state.

What changes for you

Cap the runaway agent before the bill, not after the argument.

Budget with a cutoff
Every agent gets an owner and a monthly budget with an automatic cutoff on routed calls. Tallin alerts before the threshold and freezes runaway spend after it, so an agent looping overnight stops costing money before anyone files a ticket.
One normalized ledger
Every API key, Copilot license, and seat lands in one normalized ledger attributed by actor (human, app, or agent) with cost authority and confidence on every row, so finance and security stop arguing about which dashboard is right.
Gaps as queue items
Coverage gaps surface as actionable queue items, not red flags you discover during a customer audit or board review.

Ledger view

Totals with the evidence still attached.

The ledger does not hide where numbers came from. Every row keeps the actor, provider, surface, cost, and coverage state together, so you can trace a spike back to the exact agent, app, or person that caused it.

Per-actor analysis

Read spend the way you answer for it.

Per-actor, cross-provider view
Compare spend and request volume by actor (human, app, or agent) across ChatGPT, Claude, Gemini, Copilot, API usage, and imported paths, no hyperscaler estate required.
Budget caps that enforce
Set a monthly budget per actor on routed calls. Tallin alerts before the threshold and freezes runaway spend at the gateway after it.
Explainable, refresh-honest totals
Open any rollup and see which dollars are observed, inferred, enforced, or not covered, including direct provider calls and tool side effects outside Tallin. Failed scheduled refreshes and stale data surface before old evidence becomes a leadership report.

Supported signals today

Each source contributes a labeled signal that resolves back to an actor. Some are authoritative, some are imported, and some are partial by provider design. Direct provider calls or tool side effects outside Tallin are named as not covered, never silenced.
