Thanks! Yeah the spoiler-free context was important to me. Most PDF chat tools just dump the whole thing and ruin the experience.
Single voice for now, focused on natural pacing and clarity. Multi-voice for dialogue is on the roadmap but want to nail the core experience first.
Good call on the Audible distinction. You're right, different value prop. I brought it up because those were the alternatives I found when looking for a solution, and none let me use my own files AND talk to them. The real comparison is probably Speechify/ElevenReader but they're missing the interactive piece entirely.
