02 / Why this one

Three things other log viewers don't do.

→ stays inside

Nothing uploads — or self-host it

Logs are parsed in the browser: no server, no account, works offline. Under NDA or ITAR, run the whole stack — debrief included — on your own hardware or fully air-gapped.

→ explains

A debrief, not a dump

Anomalies come ranked with a likely cause in plain language, and you can ask the log follow-up questions.

→ compares

Flight-to-flight diff

Overlay two logs to see exactly how a tune, payload or wind change moved vibration, current draw or track.

Command deploys on your own hardware or fully air-gapped — including the AI debrief, so no derived data leaves your network either. Local parsing stays free forever on VFR; the paid tiers add the debrief, comparison and reporting layer.

05 / FAQ

What is the A–F grade based on?

A composite of vibration, EKF and GPS health, failsafes and control margins — one score, with the drivers shown in the recap.

If nothing uploads, how does the AI debrief work?

Only the derived summary — grades, anomaly names, statistics — is sent for the debrief, never the raw log. Command can run it self-hosted or air-gapped so nothing leaves your network at all.

Do I need to install anything?

No. It runs in any modern browser and keeps working offline after first load.

What happens when a trial ends?

You drop back to VFR. Your logs and library stay exactly where they are — they were never on our servers.

Drop a log. Read the flight.
