Turn any topic into a finished video
From a topic to a finished video — automatically.
DuoCast is a web studio for video creators. Give it a topic: it writes a sourced script, narrates it with a synthetic voice, animates a presenter over the narration, and publishes the finished video to your own YouTube, Instagram and TikTok accounts — now or at a time you schedule.

How it works
1
Write
A script is drafted for your topic, checked against the sources it used, and left fully editable line by line.
2
Voice & cast
Pick a voice and a presenter (or generate your own cast). The narration and the animated presenter are rendered for you.
3
Publish
Send the finished landscape video, plus a vertical teaser and recap, to the accounts you have connected — now or scheduled.
What you can do
Sourced scripts
Every episode keeps the sources behind its claims, so you can check them before you publish.
Two video formats
An explainer with a single presenter and picture panel, and a fast motion format for short, punchy edits.
Your own cast
Generate a presenter that matches your channel's look, in ten visual styles, and reuse it across every episode.
Multi-platform
Connect YouTube, Instagram and TikTok per channel and publish to each — including vertical Shorts and Reels.
Scheduling
Queue uploads ahead of time; they go out on your schedule even when you are away.
Performance
See how each published video is doing — views, watch time and subscribers — inside DuoCast.
Examples
Real episodes, rendered end to end by DuoCast. Each one ships as a full landscape cut and a vertical recap for Shorts and Reels.
Results
Real channels running on DuoCast. Give it the channel's niche once — it writes, voices, edits and publishes every day on its own, with no work from you. It is cheap to run, and with a good niche, cast and topics you can triple — or 10× — these numbers.

DuoCast is the one that takes a topic all the way to published — in your own cast — for a fraction of the price of an avatar tool. Competitor figures are approximate, October 2026.
