A look inside
Screens from the app on iPhone. Answers shown are synthetic examples, not a real case.
How it works
Pick your visa type and situation, answer the questions by voice or text, and read the debrief. The estimated approval chance is shown as a range, together with every factor that moved it.
Realistic pace
Short questions, quick follow-ups, two to five minutes for visitor visas. You practise answering first and stopping.
Debrief on every answer
Purpose, ties, funding, consistency, brevity, knowledge of your own case and natural delivery, each with evidence from your answers.
Explained estimate
A range built from the official refusal rate for your nationality, your profile and your practice answers. Every weight is disclosed. It is a heuristic for training, not a prediction.
Voice or text
Speak your answer or type it, whichever feels closer to the real window.
No account, no case file
Your profile is a short set of multiple-choice answers. No passport number, no bank details, no DS-160 upload.
Source-cited estimate
The starting point is the official State Department refusal rate for your nationality and visa type, with every adjustment named.
Eight visa categories
B-1/B-2, F-1, J-1, H-1B, L-1, K-1, CR-1/IR-1 and the Diversity Visa, each with its own likely questions.
Privacy by design
No account, no advertising, no tracking. Your profile is multiple choice only, never passport or bank details. Documents are read on the phone and cleaned of contact data and ID numbers before anything is sent. Audio is deleted after transcription; interview content is deleted from the server after your debrief.
