AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.

Developer-first API for U.S. property data, valuations and address verification
Query large property datasets with strict filters so applications can surface narrow, exact matches instead of broad haystacks of results.
Access valuation outputs and cleaned, normalized data suitable for analytics, scoring and model-training pipelines.
Layer boundary geometry and map-ready endpoints into applications that need spatial context, not just tabular records.
Standardize inconsistent address formats at input time to reduce duplicate records and downstream data clean-up.
