Trust & Security
Your financial data deserves the highest standard of protection. Every feature is designed with privacy, accuracy, and transparency in mind.
Verification Pipeline
No single model decides your deductions
Every AI classification passes through three independent verification layers before a result reaches you. If any layer can't confirm the deduction, it gets flagged for review instead of being silently approved.
AI Classification
Machine learning categorizes each purchase against known tax deduction categories.
Rules Engine
Versioned tax rules match the category to specific IRC sections and regulations.
Cross-Reference Audit
Catches duplicates, validates evidence chains, and checks amount thresholds.

Full Citation Trail
Every deduction cites its source
No black-box estimates. Every deduction includes at least one tax authority citation — IRC sections, Treasury regulations, or IRS publications — so your CPA can independently verify each claim.
The example shows exactly what your accountant sees: the item, its classification, supporting legal authority, and a confidence score from the verification pipeline.
