Dev Builds Deterministic Engine to Catch AI's Financial Math Errors
MuhammadMujtaba21 · reddit · 2026-08-11
An indie developer shared a verification engine built over a year to tackle AI hallucinations in financial math. Acting as an independent deterministic layer rather than an LLM, the tool extracts source data from underlying documents (PDFs, Excel, etc.), recalculates values using exact formulas, and cross-checks them against AI-generated claims.
Currently supporting core financial ratios, the engine provides full evidence-to-conclusion traceability. The author is actively seeking harsh feedback from finance, audit, and compliance professionals to evaluate if this 'AI drafts, deterministic engine proves' approach can genuinely meet real-world auditing standards and uncover potential blind spots.
