# Häxrök — Design Review for Your KiCad Projects

Hobbyist boards often come back dead because of a single schematic mistake.

A pull-up connected to the wrong rail. UART wired TX-to-TX. A regulator that can't start itself.

Professional teams catch these problems through design reviews, reference designs, and simulation. Hobbyists? They post a screenshot to a forum and hope someone spots the mistake.

KiCad's ERC won't catch them. The connections are electrically consistent. They're just wrong.

**Häxrök brings professional-style design review to hobbyist KiCad projects.**

Drop in your KiCad project folder and choose your mode:

### Review Before You Order
Catch design mistakes before they become expensive PCBs.

- **Ranked findings:** Issues classified as *Won't Work*, *May Fail*, or *Improvement*.
- **Evidence:** Each finding points to the relevant schematic connections and explains why they matter.
- **Actionable fixes:** Get a concrete schematic correction and a verification step to perform before ordering.
- **Honest results:** If no issues are found, Häxrök says so. No invented problems. No noise.

### Debug on the Bench
Your board isn't behaving as expected? Let's figure out why.

- **Describe the symptoms:** Tell Häxrök what you observe on the bench.
- **Get ranked hypotheses:** Receive plausible root causes, ordered by likelihood, with explanations grounded in your schematic.
- **Follow bench procedures:** Get concrete steps for what to probe, measure, and test.
- **Refine with measurements:** Enter your actual measurements, and Häxrök updates its hypotheses accordingly.

**From schematic to working hardware, Häxrök helps you catch mistakes before they cost you a board—and troubleshoot them when they do.**
