Real-world ATC audio
We collect audio from real flights and public sources — busy frequencies, regional accents and phrasing, stepped-on or partial calls, radio noise and distortion. The edge cases are the whole point.
Safety · Beta
Why PilotGPT is still in beta.
In aviation, “almost right” isn't enough. We're staying in beta until ATC transcription is pilot-level accurate — not the demo-reel version.
Human verification
Before any of it enters a training set, pilots and controllers listen to the original audio and correct the transcripts — callsigns, numbers, clearances, phraseology. Only human-validated segments ever go into training.
Train, optimize, repeat
Each cycle is measured against held-out flights. Generic transcription models are tuned on podcasts and meetings. Ours is tuned on VHF AM radio with a pilot in the loop.
Our bar
Aiming for pilot-level accuracy — not podcast-level.
Generic ASR models are trained on podcasts and meetings. Aviation uses a VHF AM radio, domain-specific phraseology, numbers spoken as digits, and callsigns that do not appear in any dictionary. PilotGPT is purpose-built for that.

Questions
Frequently asked questions
How does PilotGPT work offline?+
PilotGPT uses on-device AI that runs directly on your phone or tablet, delivering offline ATC transcription alongside answers on regulations, procedures, and aircraft-specific details.
Do you support VFR and IFR?+
We source VFR and IFR maps, along with approach plates and other documents directly from the FAA so you don't have to worry about falling behind the aircraft. Whether you're on the ground planning or in the air flying, PilotGPT can access maps or documents you need.
Which aircraft are supported?+
PilotGPT supports hundreds of aircraft including popular models like Cessna 172, Piper Cherokee, Cirrus SR20/22, Diamond DA40, Beechcraft Bonanza, and many more. We're constantly adding new aircraft to our database.
How much does PilotGPT cost?+
PilotGPT costs $49.99/month, but $29.99/month for student pilots, CFI's or if you're heading towards the airline. We know how difficult it is, so take a discount to stay sharp, avoid mistakes and fly safer.
Do you offer discounts for flight schools?+
Yes, we offer special pricing for flight schools and aviation organizations. Contact us for pricing details.
