WilcoAI is an iPhone and iPad app that lets pilots rehearse ATC radio calls out loud against an AI controller and grades every readback against FAA standard phraseology.
Built for student pilots before a checkride, instrument students drilling clearances, and rated pilots staying current.
Free download · iPhone & iPad · iOS 26+
Every session is push-to-talk and scored. Free gets you a daily call; First Officer adds drills, and Captain adds Phase Block and Full Flight.
The controller speaks a synthetic ATC transmission through your earpiece. When it finishes, hold the push-to-talk button, speak your readback out loud, and release to send — the same half-duplex rhythm as a real radio, no typing.
WilcoAI scores each response on correctness, clarity, and speed against FAA standard phraseology. The debrief shows what you got right, what you missed, what to watch out for, and your transcript. Quick Drill tags every category with its FAA reference.
Quick Drill isolates a single category: ground, tower, departure, approach, or an emergency call. Repeat the exact phrase you are weak on. A set is 10 reps.
Full Flight is a complete scenario from clearance to shutdown. Multiple AI controller voices cover ground, tower, departure, center, and approach, and the controller pushes back when you miss.
One freshly generated ATC transmission lands every day, about sixty to ninety seconds end to end, free on every tier. A streak counter tracks every day you practice, whether or not you subscribe.
Multiple AI voices are spread across ground, tower, departure, center, and approach, so a hand-off sounds like a hand-off. In Phase Block and Full Flight, the controller pushes back: it says negative or correction on a wrong or missing item, and asks you to say again after a failed call.
Inside the app
Hold the push-to-talk button and read it back out loud. The controller spoke by audio — your job is to repeat it correctly, concisely, and fast.
Correctness, clarity, and speed, scored after each readback. The debrief shows what you got right, what you missed, what to watch out for, and your transcript.
Your Daily Challenge leads the Home screen, with Quick Drill, Phase Block, and Full Flight right below it. Locked modes show a buy-credits row that opens the matching credit packs. Your current aircraft and home airport are always set and ready.
One scenario lands every day, free. Your callsign is already loaded — tap Play and hear the controller call before you key the mic.
VFR or IFR. Filter by phase: ground, tower, departure, emergency. Then pick a category. Each row shows the FAA reference it trains.
Rehearse VFR pattern calls and towered-field comms before you ever key the mic solo or fly the checkride.
Drill IFR clearance copies, holds, and approach hand-offs the same way you will hear them in the airplane.
Practice any procedure at any airport you are about to fly, from a familiar tower to an unfamiliar Class B.
Warm up the radio before a flight review, so the first real call is not the first one in months.

Synthetic. Every controller transmission is generated and spoken by AI text-to-speech, never recorded from a real frequency and never rebroadcast air traffic control. WilcoAI is a training aid only, not for flight use, and nothing it generates should ever be treated as a real clearance.
No. WilcoAI is a ground-school training aid, not an FAA-approved product, and it is not for flight use. Never act on a simulated clearance.
WilcoAI scores each response on correctness, clarity, and speed against FAA standard phraseology. The debrief shows what you got right, what you missed, what to watch out for, and your transcript. Quick Drill tags every category with its FAA reference. Standards come from the FAA's own publications.
Yes. WilcoAI grades both VFR and IFR readbacks, and instrument students can drill IFR readbacks in Quick Drill, which has a VFR and IFR toggle.
No. WilcoAI requires no account and no sign-in — set a callsign and aircraft once and start practicing. It does require an internet connection: the controller, the grading, and the voices are all generated server-side, so there is no offline mode.
One Daily Challenge attempt every day, free forever, plus a streak counter and badges. Quick Drill, Phase Block, and Full Flight require First Officer or Captain, though one-time credit packs let any tier try a Full Flight or Phase Block without subscribing.
Yes, on the annual plan only, for new subscribers. Both First Officer at $19.99 a year and Captain at $49.99 a year include a 14-day free trial; monthly billing has no trial. Subscriptions auto-renew through the App Store and cancel anytime from iOS Settings.
Quick Drill covers ground, tower, departure, approach, and emergency calls, 10 reps to a set, so you can drill the exact phase you want. Phase Block and Full Flight are the longer scenario modes on the Captain plan, and credit packs let any tier try them.
WilcoAI's phraseology, procedures, and grading are pulled from the FAA's own publications at inference time:
WilcoAI is a ground-school tool. Phraseology, procedures, and grading reference FAA JO 7110.65, AIM, the Pilot/Controller Glossary, and AC 90-66. Those documents remain the source of truth. Nothing WilcoAI generates is a real clearance. The app does not replace a CFI, a DPE, or an official FAA publication.

Guides
Practice standard ATC words and numbers out loud. AIM chapter 4 phraseology and the Pilot/Controller Glossary, scored on the readback.
Practice CTAF radio calls out loud. Pattern position reports, and the difference between a UNICOM station and the common traffic advisory frequency.
Practice an IFR clearance readback out loud. Clearance limit, route, altitude, frequency, transponder, say again, and a void time.
Practice first solo radio calls out loud. Student pilot on the first call, towered and non-towered airports, and how to ask for help.
Practice taxi and hold short readbacks out loud. Runway assignment, hold short, and line up and wait, the way AIM 4-3-18 requires the readback.
