Practical software for students and vehicle engineers.
Karasoy Labs builds focused tools around problems we know first-hand: preparing for a high-stakes exam, and tracking down faults on electric vehicles.
Two products, built from real workflows
Each one starts from structured knowledge of the domain, with AI used where it saves people time.
KavrIQ
A study platform for the KPSS, the exam used for public-sector hiring in Turkey. Every subtopic has a lesson, a summary card and a 20-question practice set that gets harder as the student moves forward. A daily plan adapts to the questions a student misses.
- 6 subjects, 356 subtopics
- Adaptive daily plan
- Spaced-repetition review
- AI-drafted, human-reviewed content
DTC Analyzer
A desktop tool for working through vehicle diagnostic trouble codes. It groups fault codes by vehicle and over time, flags codes that keep showing up without a real underlying fault, and keeps notes on known issues so the next technician does not start from scratch.
- Fleet history database
- Noise-code detection
- Built-in knowledge base
- One-click reports for email and tickets
| Code | Description | Seen | Triage |
|---|---|---|---|
| P0A80 | Replace hybrid/EV battery pack | 2× | Investigate |
| U0100 | Lost communication with ECM | 14× | Likely noise |
| P0AA6 | HV isolation fault | 3× | Known issue |
| B1325 | Low-voltage supply out of range | 9× | Likely noise |
Hi, I’m Sait Karasoy, the founder.
I’m an electrical engineer and have spent most of my career on electric vehicles, from battery systems and high-voltage architecture to diagnosing faults on vehicles in the field. DTC Analyzer grew out of that diagnostic work.
KavrIQ is built together with a friend who leads the lesson and question content. I write most of the code myself in Python and Next.js.
