Two engines. Every number yours.
The engines below are the deterministic half of AIChieve: you supply the inputs, they return a verdict and the arithmetic behind it. Nothing is uploaded, nothing is estimated on your behalf, and both stay free.
Compute Infrastructure
GPU TCO Analyzer
Model a local GPU workstation or cluster against rented capacity — hardware, TDP load, persistent storage, depreciation and the utilization floor at which owning stops paying.
Output · Local Build vs. Cloud Lease
Decide: build the cluster or lease the capacity
Build vs. Buy
Master Asset & Software TCO Calculator
Score a custom build against a bought platform on fully loaded engineer-years, compliance certification, maintenance headcount and roadmap opportunity cost — then stress-test it for sunk-cost and key-person bias.
Output · Loaded Build-vs-Buy Score
Decide: build the system or buy it
When the decision needs a real file
The paid half
Engines answer questions you can type in. These answer questions that only exist inside a file — a carrier invoice, a vendor’s business case, an AI provider bill, a payout export.
SpendProof
AI provider invoice ↔ tagged-usage reconciliation
ParcelProof
Carrier invoice DIM-weight and surcharge audit
CaseProof
Buyer-side audit of a warehouse-automation business case
FacturGate
EU e-invoice pre-send gate and Factur-X / UBL converter
LedgerLink
Stripe payout → general ledger reconciliation engine
