TitleGuard

Agentic land-title fraud checks for Tamil Nadu property documents, built on Meta Muse Spark. Buying land in Tamil Nadu means trusting a stack of part-Tamil, part-English papers: the Patta, Chitta, Encumbrance Certificate (EC) and sale deed. Fraud hides in the gaps between them: a seller who is not on the patta, a co-owner left out, a deed selling survey 45/3B when the patta holds 45/3A, 40 cents sold on a 30-cent patta, or a bank mortgage never released. Today only a lawyer reading every page catches this, so most small buyers skip it. TitleGuard reads the documents with Muse Spark vision and structured output (Tamil and English to JSON), then a Muse Spark tool-calling agent cross-checks every field across documents using five deterministic rule tools (EC coverage, owner names with Tamil transliteration and co-owner check, survey numbers, extents across hectare/acre/cent/sq.ft, unreleased encumbrances). Findings only come from tools, so the model cannot invent a fraud flag. The result is a risk report with red flags, why they matter, what to ask the seller, and the full agent trace. The Meta key stays server-side. A labelled demo mode runs the same agent on four fictional Madurai-area cases. Built by a Madurai real-estate business owner for the buyers he meets every week.
