Featured product · Mar 2026 – Present
AI knowledge assistant & document intelligence suite
Multi-tenant AI suite with two products built end to end: Knowledge Assistant turns a company's documents into a grounded, citation-backed assistant across web chat, an embeddable widget, and WhatsApp; Document Scout screens and ranks documents against requirements with source-quoted verification. Validated internally, with HR using Document Scout to screen CVs.
Ask questions over company documents and get grounded answers with citations — on web chat, an embeddable widget, and WhatsApp.
Give it requirements and a set of documents; it extracts fields, verifies them with quoted sources, and returns an explainable ranked shortlist.
