Build a focused long-form listening product that imports user-authorized text from PDFs^?, shared web pages, personal documents, and supported ebook workflows. It would preprocess each document into a stable narration queue, preserve sentence-level progress, continue through formatting boundaries, and provide explicit voice, pronunciation, pacing, and auto-play controls. The first version should prioritize dependable playback and recovery over theatrical multi-character narration.

Natural speech generation is increasingly accessible, but the reviews show that dependable ingestion and playback remain unresolved across years of product updates. Consumers already compare alternatives and pay substantial subscriptions when a product can import otherwise inconvenient reading material.
