Problem

Mobility records can be confusing, while the safest next step often lives across several official services.

What I built

A guided, browser-local review for e-Challan evidence and FASTag transactions, with separate real-review and synthetic-demo paths.

Product decision

Keep citizen records on the device, make uncertainty visible, and never imitate government access the product does not have.

Current outcome

Selected among the Top 250 in the Build What Moves India hackathon. A working public early-access experience with dedicated review, demo, and FASTag routes.

Boundaries

ChallanSakshi does not file disputes, pay challans, authenticate records, connect to government or bank systems, or determine legal validity.

Next

Continue improving evidence extraction and guided explanations without weakening those privacy and authority boundaries.
