Hey Product Hunt! I'm Salman, a solo dev. I built Line Echo because actors rehearsing alone have a frustrating choice: beg a friend to read lines, pay $20-50/session for a reader, or talk to a flat robotic voice that kills any real emotion in the scene. Line Echo is an AI scene partner that actually understands HOW a line should sound. Upload a screenplay PDF - it auto-detects characters, analyzes the emotion of every line (angry, tender, sarcastic, desperate - 16 sentiments total), and reads them back with matching delivery using realistic AI voices. What makes it different: - Sentiment-aware voice delivery (no other tool does this) - On-device speech recognition - your audio never leaves your browser - Full pipeline: PDF upload to rehearsal in under a minute - 28+ natural voices to assign to characters Free tier available - upload a script and try it right now. Been building this solo since January. Would love honest feedback from the PH community - especially if you know any actors!
