Record the conversation. Get a transcript that says who said what. Nothing ever leaves your phone. Interview is a recorder for conversations that can't leak: client meetings, interviews, research sessions, anything you'd rather keep to yourself. Tap Record, talk, tap Done. Minutes later you have a transcript with every line labeled by the person who said it. All of it happens on your phone. No account, no servers, no upload. The only way an interview leaves your phone is when you share it yourself. KNOWS WHO'S TALKING Interview tells the voices in the room apart and labels every line. Name a speaker once and everything they said is labeled. If it isn't sure, it asks instead of guessing. REMEMBERS THE PEOPLE YOU INTERVIEW Name someone once and Interview recognizes them next time. It learns your own voice during setup, so you're labeled automatically. Remembered voices are yours to delete, any time. SHARE ON YOUR TERMS Send the transcript as text, Markdown, Word or PDF, with or without the audio. Nothing is shared until you choose to. SPEAKS YOUR LANGUAGE Transcribes English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Mandarin and Cantonese, and picks the language on its own. Some languages need a one-time download from Apple the first time. ALREADY HAVE A RECORDING? Import audio or video, or paste a link to an episode or audio file, and get the same transcript. PRIVATE BY DESIGN • No account, no sign-in • No servers, no upload • Delete means gone Made for anyone who cares about privacy. Lawyers, journalists and researchers use it, and so can anyone who'd rather keep a conversation their own. Works best on iPhone 12 or later. Titles and summaries need Apple Intelligence.

Verdict
The clearest difference is ads: Interview at none against Steel's shown. Interview also leads on update cadence (weekly vs every 4 months) and review sentiment (75% vs 64%). Steel's advantage is iOS requirement (17.6 vs 26.4). On price, in-app purchases and device support there is nothing between them.
