Truthifi resolves five systematic data problems that would otherwise silently degrade your AI's answers: Security identification — resolves the full security universe, including CITs, private securities, municipal bonds, options, and futures that aggregators typically misclassify or ignore. Transaction semantics — corrects miscoded transaction types at the source, so every downstream calculation — performance, fees, taxes, risk — is built from accurate inputs rather than inherited errors. Stale snapshots — reconstructs your full financial history from the earliest available transaction, not just from account creation. Your AI gets years of clean context from day one. Broken histories — rebuilds performance and transaction records when brokerage connections drop, keeping your timeline intact regardless of sync interruptions. Missing signals — structures data to surface findings across hundreds of signal types that would remain buried in unprocessed raw data.
