The Problem

Your check engine light comes on. You have two options: ignore it and hope for the best, or pay $100+ for a diagnostic at a shop that might tell you nothing useful.

Diagnostic anxiety: That warning light could mean a loose gas cap or a failing transmission. Without context, every warning feels catastrophic.

Information asymmetry: Mechanics speak in codes and jargon. P0301? MAF sensor? You nod along while they quote you $1,500.

Safety uncertainty: Is it safe to drive? Can it wait until Monday? Nobody gives you a straight answer.

Helios bridges the gap between your vehicle's diagnostic data and plain English understanding.

Helios connects directly to your vehicle's OBD-II port via Bluetooth. No dealership equipment required. Live sensor data streams to your phone or browser while you drive.

Live Sensor Monitoring

RPM, speed, coolant temperature, voltage, engine load, throttle position, MAF, fuel level. Updated every 100-2000ms.

Multi-Connection Modes

Web Bluetooth for browsers. Bluetooth Classic for Android. Wired USB/serial for shop diagnostics. Your choice.

DTC Code Intelligence

3,000+ codes. RAG-enhanced understanding.

When your car throws a code, Helios doesn't just look it up in a table. It uses vector similarity search to find related issues, symptoms, and solutions from a comprehensive knowledge base.

Extended Code Coverage

Powertrain (P), Chassis (C), Body (B), Network (U). Including hybrid/EV codes like P0A80 for high-voltage battery issues.

RAG-Enhanced Responses

Pinecone vector search + Firestore metadata. Finds related codes, common symptoms, root causes, and proven solutions.

Repair Cost Predictions

Know before you go. ML-powered estimates.

Powered by Pythia, our machine learning repair cost predictor. Before you visit the shop, know what to expect. Low-end, high-end, and confidence levels for every diagnosis.

Data-Driven Estimates

Trained on repair data across makes and models. Vehicle-specific predictions, not generic ranges.

Confidence Scoring

Every estimate comes with a confidence level. Know when the prediction is solid vs. when you need a second opinion.

Voice-First Interface

Hands on the wheel. Helios in your ear.

Ask questions while you drive. Helios listens, understands, and responds with synthesized speech. No looking at screens. No typing. Just conversation.

Speech Recognition

Web Speech API with interim results. Ask "What does that warning light mean?" and get an answer in seconds.

Text-to-Speech

Natural voice responses via ElevenLabs or browser TTS fallback. Helios speaks while you focus on the road.

Safety Assessment

Every diagnostic comes with a safety evaluation using the SAFER framework. No more guessing if it's okay to drive.

THE SAFER FRAMEWORK
S
Summary
A

Safe to Drive

No critical issues detected. Continue normal operation. Monitor for changes.

Service Soon

Non-critical issue detected. Schedule service within 1-2 weeks. Safe for normal driving.

Do Not Drive
