01 / CONNECT
Plug in and pair over Bluetooth
Connect a compatible adapter to the vehicle's OBD-II port, pair it with the mobile app, and let CogniOBD manage connection, reconnection, and data buffering during drives.
A clearer conversation with your car
Your car speaks in signals. CogniOBD translates.
Pair a compatible Bluetooth OBD-II adapter and CogniOBD learns what your vehicle can report, follows supported readings across drives, and turns meaningful change into clear guidance: continue monitoring, inspect soon, or give it urgent attention.

Plug in. Pair.
Let CogniOBD listen.
Different vehicles expose different generic OBD readings. CogniOBD tests the connection first, builds a capability profile for that car, and only monitors signals it can actually support.
02 / LEARN
Learn what this car can report
A capability scan probes supported OBD signals, records what is unavailable, and creates a vehicle-specific polling plan instead of assuming every car is the same.
03 / UNDERSTAND
Follow change across drives
Compact readings are buffered safely, synced to the platform, and compared over time so repeated drift can stand out from one noisy sample.
From readings to plain language
A signal is data.
A pattern is a story.
CogniOBD keeps collection, vehicle-health inference, alert controls, and explanation separate. Rules and the trained health module identify meaningful patterns; the platform checks evidence and confidence; then a clear explanation tells the driver what changed, why it matters, and what to do next.
01Capability profiles keep unsupported readings out of the evidence.
02Local buffering protects trip continuity when the network is weak.
03Confidence gates and cooldowns reduce noisy, repeated alerts.

PLAIN-LANGUAGE SUMMARY
Coolant temperature is running above this vehicle's normal pattern. Generic OBD data cannot confirm the exact cause, so the change is worth monitoring and inspecting if it continues.
CAPABILITY / 04
Built for the car you actually drive
Generic OBD-II is not dealer-level diagnostics, and not every vehicle exposes the same signals. CogniOBD adapts its monitoring plan and makes those limits visible.
AVAILABLELIMITED
Confidence without false certainty
Useful because it knows
what it cannot confirm.
Capability first
Unsupported readings stay unavailable instead of becoming invented evidence or false certainty.
HONEST_DATAConservative alerts
Severity, confidence, evidence, and alert controls determine whether a finding should interrupt the driver.
ALERT_QUALITYClear next actions
Guidance stays practical: continue monitoring, inspect soon, or give the issue urgent attention.
DRIVER_CONTEXTDesigned for drivers, not technicians
Your car already has a story.
Start understanding it.
