The Opportunity

Problem

Solo founders lack CAN bus expertise required to develop connected car features, blocking their product progress.

Solution

Upload OBD/CAN capture files and get human-readable decodings for 1000+ PIDs across models. Visual dashboards show sensors, faults, and trends over time. Export to JSON/CSV for your app integration, accelerating feature dev.

Target Audience

Solo founders building connected car applications or IoT features for vehicles

Differentiator

AI-assisted PID matching with 99% accuracy on unknown messages via community DB.
