Castique turns the articles, notes, and ideas you mean to read into an AI podcast you can actually listen to - a natural back-and-forth between two hosts, Joe and Jane. Paste a link, import a PDF, paste text, or type a topic. Choose a language, format, and length, and Castique writes a tight script and voices it. Your episode is then ready for the drive, the train, or the dishes. FEATURES - Link, text, topic, or PDF in - a finished audio episode out - Two-host conversation, not a flat read-aloud - 30 podcast languages, including English, Turkish, Spanish, German, French, Portuguese, Arabic, Japanese, Korean, Hindi, Italian, Chinese, and more - Formats: Conversation, Debate, Interview, or Explainer - Lengths: Standard or Extended (about 15 minutes) - Background playback with Lock Screen and Now Playing controls - Highlights and full transcript for every episode - Private, on-device history for generated episodes - Save audio to Files, iCloud Drive, or another destination you choose - Share a link straight from Safari into Castique (iOS) - Native on iPhone and iPad No account required. Just paste and press play. Castique generates audio using AI from the content you provide. Audio quality and accuracy depend on the source article. Podcast generation uses credits.
