Deterministic calculations
Fixed-precision component calculations keep financial math outside the language model.
Inputs + outputs + lineage Tax decisions you can defend
Turn tax complexity into clear, reviewable decisions.
Bring calculations, rule evidence, transaction history, and AI-assisted research into one controlled workspace for US and Canadian tax operations.

Designed for finance teams, accounting practices, marketplaces, and operators who need speed without losing traceability.
AI-assisted research
Use AI to surface missing facts and explain evidence while preserving a clear professional-review boundary.
Structured, transparent answersNexus intelligence
A planned workflow for tracking physical and economic signals, thresholds, and registrations.
Roadmap capabilityDocument intelligence
A planned review surface for invoices, exemption certificates, notices, and extracted facts.
Roadmap capabilityBulk operations
A future import workflow with validation, progress, retries, and row-level exceptions.
Roadmap capabilityCalculation history
Preserve transaction inputs, rule versions, component results, and evidence for later review.
Available in the demoDesigned for accountability
AI explains. Your rules calculate.
The model helps interpret questions and communicate results. Effective-dated rules and fixed-precision code remain the source of calculated amounts.
Capture facts
Start with amount, transaction date, jurisdiction, and exemption status.
Resolve a rule
Select an explicit jurisdiction rule and its effective version.
Calculate
Apply component rates with deterministic fixed-precision math.
Review evidence
Inspect the source, assumptions, limitations, and saved history.
Transparent demo scopeInspect the live rule library
A credible foundation, with honest boundaries.
The current investor demonstration supports base-rate examples for six jurisdictions. It does not claim complete local-rate, nexus, product-taxability, filing, or legal-advice coverage.
United StatesCalifornia, New York, and Texas base-rate scenarios
CanadaOntario, British Columbia, and Quebec component scenarios
Security by design
Built around isolation, traceability, and least privilege.
The demonstration implements secure sessions and organization-scoped access as the foundation for a production control plane.
Tenant-scoped accessUsers operate inside an explicitly selected organization.
Secure authenticationHashed passwords, revocable sessions, and MFA-ready flow.
Reviewable lineageCalculations retain rule versions and authority links.
Safe defaultsStrict browser policy, rate limits, and bounded inputs.
