Kendin Bak: an AI car help app, built by us, in real use today
How we ship our own products with the same 360 degree process we use for clients.
Challenge: Build a mobile app that uses AI to help non-technical drivers understand what is wrong with their car, in two languages, safely.
Project Overview
Kendin Bak ("check it yourself" in Turkish) is one of our own products. It is also a public demonstration of the work we do for clients. The app lets a driver describe a noise, a warning light, or a problem they are seeing and returns a likely cause and the next step. It is live at https://kendinbak.ibgroup.dev and is used today by Turkish drivers.
The Problem
Most drivers do not know what is wrong with their car when something feels off. They cannot describe the issue to a mechanic in technical terms, and they do not know if the problem is urgent. The cost is either an unnecessary garage visit or a problem that gets worse before they act on it.
Our Solution
A conversational mobile app that takes everyday descriptions of symptoms and returns the most likely cause plus what to do next, in plain language. AI does the matching. We did the engineering.
Kendin Bak: Automotive AI Diagnosis App
Our own production mobile app: AI-powered help for drivers to figure out what is wrong with their car. Bilingual, in real use today.

What we wanted to prove with our own product
AI that does not hallucinate when it matters
A car symptom mistaken for the wrong cause is at best annoying and at worst dangerous. The system prompt and response shaping had to keep the AI inside the lane of known automotive patterns and tell the user to see a mechanic when confidence is low.
Challenge #1
Bilingual from day one
Turkish drivers describe symptoms in Turkish. We refused to build an English-first app with a translation layer bolted on. Turkish and English are first-class on the same input pipeline.
Challenge #2
Safety in the UX itself
An app used by drivers should never push them to use it while driving. The whole interaction is voice-friendly and never assumes attention is fully available.
Challenge #3
Our solution
Production-grade AI with a small, focused team
We built Kendin Bak with React Native, TypeScript, and the Claude API. The system prompt is tight, the AI is asked to surface confidence, and low-confidence answers always point the user to a real mechanic. The UI is deliberately calm and minimal.
We treated Kendin Bak as a client project for ourselves, including the same 360 degree review we sell: security, function, and legal data handling all passed before launch.
If we will not ship our own product without these checks, we will not let our clients either.
What the app does
Practical features for everyday drivers
Conversational symptom intake
The driver describes the problem in their own words: a sound, a smell, a warning light, a behavior.
Benefit: No need to learn car vocabulary to ask for help.
Feature #1
AI-assisted probable cause
The model returns the most likely cause and a confidence indicator. Low confidence answers always include 'see a mechanic'.
Benefit: Useful answers without the false certainty that gets drivers in trouble.
Feature #2
Bilingual: Turkish and English
Symptoms can be described in either language. The model is asked to respond in the language of the question.
Benefit: Natural for Turkish drivers, accessible to international users.
Feature #3
Privacy by default
No personal information is required to use the app. We do not collect what we do not need.
Benefit: Trust is the product.
Feature #4
Where Kendin Bak is today
Honest status: shipped, bilingual, in production
What is next for Kendin Bak
We continue to iterate on the app based on what users actually ask for. We also use it as a public reference for clients: when a founder asks if we can ship an AI mobile app, we point at Kendin Bak.
Want a production AI app of your own?
We do this for clients the same way we did it for ourselves
Kendin Bak is the proof that the 360 degree review we sell is the same one we use on our own products. We can build the same way for you, paid safely through Upwork with only 10% upfront.
Honest production status: shipped, bilingual, used by real drivers today.
