Questions
How accurate is extraction?
High for structured documents, with a review screen for anything uncertain.
Will the AI make things up?
Less, when it answers only from retrieved documents and declines when it has nothing; we build that in and measure it.
MVP first or full product?
MVP first: 4–8 weeks to a version real users can pay for, then iterate. A full platform is 12–20 weeks.
