Three seconds. One root cause. One patch.

Paste. Don't type.

Drag a log file, pipe serial in live, or paste 50,000 lines. SerialDoctor reads every backtrace, panic, and HAL assertion.

Root cause, not guesses.

Trained on 4.2M real crashes across ESP-IDF, Zephyr, FreeRTOS, Arduino, and custom RTOSes. It doesn't match strings — it reasons.

Fix, not advice.

You get a unified diff against your repo. Copy it, apply it, push. Avg. fix is 12 lines.

We shipped the board 3 weeks early. SerialDoctor caught a race condition in the SPI driver that would have cost us the Q3 launch window.
