VoiceBrief

VoiceBrief turns PDFs, handwritten notes, and URLs into audio lessons with synchronized text highlighting. Designed for students tackling dense academic material, it lets you listen during commutes or exercise while staying oriented in your source document. The free preview plays a short section; Pro ($9.99/month) unlocks full MP3 downloads, voice chat with your documents, quiz generation, and cross-device resumable playback.

The app syncs audio to your original text as it plays, helping you follow complex passages without losing your place. You can pause mid-lesson to ask questions about highlighted sections, then jump back to exactly where you left off. The maker built VoiceBrief with Lovable.
