DuoCast
Turn any doc into two voices.
Paste a PDF, doc, or URL — hear it as a warm, two-host podcast on your commute. Built for Chinese & Japanese, not just English.
Listening, not reading
Drop in a document and get a natural two-host conversation you can actually finish on the way to work.
Two hosts who actually talk
Host A asks and reacts, Host B explains — a real back-and-forth conversation, not a monotone reading. You hear who's speaking at a glance.
Native-grade 中文 & 日本語
Self-hosted CosyVoice / F5-TTS voices with natural Chinese and Japanese tone, pacing, and pauses — never the robotic cloud-TTS sound.
Paste, upload, or drop a URL
Three ways in, one simple action. Paste long text, upload a PDF or Word doc, or drop an article URL — we pull the content and script it.
Player that follows along
A scrolling transcript highlights each line in sync with playback. Tap any line to jump there. Chapters let you skip around long episodes.
Fits your whole commute
Episodes run 5–15 minutes — the length of a real commute or a walk. Long PDFs generate in the background; leave and come back.
Long docs, full length
Self-hosted means zero per-character cost, so a whole e-book or long report gets voiced end-to-end — not truncated like metered cloud TTS.
