About DuoCast
DuoCast is a tool that turns documents into two-host podcasts. Users can paste text, upload a PDF or DOCX, or paste an article link to generate a 5–15 minute conversational episode in which two hosts ask each other questions, respond, and explain, complete with chapters and a scrubbable synced transcript—great for listening on the commute. Voices are available in Chinese and English, and the official site says Japanese is coming soon, describing its voices as self-hosted rather than default cloud robotic voices. Every document comes with a free 3-minute preview; upgrading to Pro ($12/mo) unlocks full episodes from source texts of up to 50,000 words plus MP3 downloads, or you can buy a one-time $9 credit pack (20 full episodes, credits never expire, no subscription).
