The Engineer's Toolkit
Universal Telemetry
Full native support for ArduPilot .bin/.log/.tlog and PX4 .ulg. One upload, one platform — no converting, no separate tools for each flight stack.
Share with a Link
Your team shouldn't need to download 500MB files. Send a single URL to stakeholders to review the same flight instantly.
Vector AI Copilot
The only flight analysis platform with a conversational AI interface. Ask about EKF anomalies, battery sag, or vibration — and get answers grounded in your actual telemetry data.
Forensic PDF Reports
No other tool generates a downloadable audit document from your log. Ten sections: flight grade, system health, weather at flight time, motor balance, anomaly log, and a prioritised maintenance plan.

Common Questions
Everything you need to know about the platform.
Which flight log formats does LogHat support?
ArduPilot DataFlash logs (.bin, .log, .tlog) and PX4 ULog files (.ulg, .ulog) are both fully supported in production. LogHat auto-detects the format — no conversion or separate tools required for different flight stacks.
Does LogHat use AI for diagnosis?
Yes. LogHat includes Vector AI, a conversational diagnostic assistant. You can ask questions in plain English — for example, whether there were EKF anomalies, whether battery sag occurred during the climb, or what caused a mode change — and Vector AI responds with answers grounded in your actual telemetry. No other flight log platform offers this. Available on paid plans.
Can I export my analysis as a report?
Yes. LogHat generates a 10-section Forensic PDF Report: flight grade, system health summary, EKF analysis, battery profile, Open-Meteo weather at your flight location and time, motor balance, vibration analysis, GPS health, annotated anomaly log, and a prioritised maintenance action plan. No other log analysis tool generates a downloadable audit document from raw telemetry. Available on paid plans.
What exactly is LogHat?
LogHat is a high-fidelity flight intelligence platform built for ArduPilot and PX4 operators. It was born from our own intensive R&D to bridge the gap between raw sensor data and physical flight maneuvers. While standard tools show you what happened, LogHat shows you where and why it happened through synchronized 3D visualization.
Where does LogHat fit into my current workflow?
Think of it this way: Mission Planner and QGroundControl are for configuring and flying your drone. LogHat is for understanding the flight after it happens. It fits perfectly between the test flight and your final engineering report, replacing manual spreadsheet analysis with instant visual context.
Why should I use this over standard, free log viewers?
Standard viewers are often offline, complex, and isolated. LogHat is a web-native, collaborative environment that correlates parameters (like vibration or battery sag) directly onto a 3D flight trail. It allows you to share a "digital twin" of your flight with a single URL, saving your team hours of disjointed debugging.
Is it only for professional logistics drones?
No. LogHat is built for any aircraft running ArduPilot or PX4. Whether you are tuning a 5-inch FPV racer, testing a heavy-lift industrial quad, or developing a commercial-grade VTOL air taxi, the physics of the logs remain the same—and so does our ability to visualize them.
What is the "Founding Pilot" program?
We're in a dedicated Beta phase. Every Founding Pilot gets 3 free Flight Reports on signup — no credit card, no time limit — plus a direct seat at our development table via the in-dashboard Feature Request tool, so you help shape the exact tools you need for your drone projects.
