The Opportunity

Problem

Solo operators deploying K-12 attendance tracking face high churn from integration failures with legacy government systems, blocking solo scaling.

Solution

Upload sample data and a legacy spec PDF; AI infers mappings, generates adapters, and provides embeddable JS widget for your app. It handles edge cases like date formats and validation rules unique to each state DOE system. Your customers get seamless 'export & submit' without your team touching code.

Target Audience

Solo edtech entrepreneurs or developers selling attendance tracking software to K-12 schools

Differentiator

AI-powered format inference from PDFs/docs + embeddable widget—adapts dynamically as districts change rules.
