Aha! moments building Superlore.ai
Hey builders! 👋
Wanted to share an interesting technical challenge I solved while building Superlore (the AI on demand long-form audio documentary generator).
The Problem:
Traditional AI podcast tools take 10-15 minutes to generate a 15-minute episode. This kills the spontaneity of learning—by the time your episode is ready, you've moved on.
The Goal:
Get time-to-first-playable under 30 seconds while maintaining quality.
The Solution - Streaming Pipeline Architecture:
Stream the script - GPT-5 Real-time API writes and streams segments as it goes
Parallel processing - Voice synthesis (Kokoro-82M) and sound design run simultaneously
Music-aligned chunks - Content segments match natural music bed durations
Progressive assembly - Chapters become playable as soon as they're done
Low-reasoning script drafting - Less time spent figuring out script length means faster processing
Key Insights:
Don't wait for full script before starting voice synthesis
Parallel > Sequential (obvious but easy to forget)
User experience = time to first playable, not total generation time
Still have lots to learn, but making insights like this along the way makes learning feel really fulfilling.
Would love feedback on Superlore if you're able to check it out! Any tips and tricks would be helpful too!
