Nichecast — everything but the publish button.
Nichecast is a tool that turns a niche you describe into finished faceless YouTube shorts: it writes the script, records the voiceover, renders a captioned 9:16 video, and uploads it to your own YouTube channel. It takes the 30 minutes of editing and captioning off every video.
Every video arrives unlisted, and Nichecast never publishes one. The upload lands in your YouTube Studio as an unlisted draft — nobody can find it until you watch it, edit the title or thumbnail if you want to, and press publish yourself. That is deliberate: a channel is yours, and YouTube's own inauthentic-content policy asks that a video made with automated tools still show your creative judgement. Ours is the step where you supply it.
Every video is held to a content standard: the script is checked before it's recorded, and every stock clip and photo is reviewed before it goes on screen. Anything that doesn't pass is left out — a scene runs empty rather than showing what it shouldn't. You can add your own rules per channel on top of that, and they're enforced the same way.
When you connect a channel, Nichecast asks for access to your YouTube account for one purpose only: uploading the videos it creates for you to that channel. You can disconnect the channel at any time, which revokes that access — see the privacy policy for details.
Watch one it made
Nobody should have to sign up to find out what comes out. This is a full run — a niche, one topic, and the file the pipeline handed back.
Why a Venus Day Is Longer Than Its Year — faceless explainer, 65 seconds, from a sample channel called Orbit Notes.
Nichecast made all of it: the script, the voiceover, the captions and the render. Nothing was edited afterwards — it is only re-encoded smaller to sit on this page. On a real channel this same file lands in your YouTube Studio as an unlisted draft, and it stays unlisted until you press publish.
Read the script it wrote
- Venus is the slowest-rotating planet in the solar system, taking 243 Earth days to spin just once on its axis.
- But it only takes Venus about 225 Earth days to complete a full orbit around the Sun.
- That means a single day on Venus is actually longer than its entire year.
- If you stood on the surface, you would watch the Sun rise in the west and set in the east.
- Venus rotates backwards compared to Earth and most other planets, which astronomers call retrograde rotation.
- Its solar day, the time from one sunrise to the next, works out to about 117 Earth days.
- That means you would get only two sunrises in the time it takes Venus to rotate once completely.
- And remarkably, the length of a Venus day is not fixed. It actually changes by a few minutes over time.
- The planet's incredibly thick atmosphere pushes and pulls on its rotation, slightly speeding it up or slowing it down.
- So on Venus, a day lasts longer than a year, and no two days are exactly the same length.
A different style, same pipeline
Every slide here is drawn from a character you describe once, so it stays the same character all the way through. Videos in this style are declared Made for Kids on YouTube.
Pip and Leo's First Sunflower — kids picture-book story, 39 seconds, from a sample channel called Little Spout.
Nichecast made all of it: the script, the voiceover, the captions and the render. Nothing was edited afterwards — it is only re-encoded smaller to sit on this page. On a real channel this same file lands in your YouTube Studio as an unlisted draft, and it stays unlisted until you press publish.
Read the script it wrote
- Pip holds a tiny sunflower seed in the palm of her hand.
- Her neighbour Leo watches quietly from behind the wooden fence.
- Pip waves and shows Leo the little seed in her hand.
- Leo steps through the gate and holds the seed for the very first time.
- Together they pat the soil down and give it a careful sprinkle of water.
- Every morning they look, but the pot looks the same for many days.
- Then one morning a tiny green shoot pushes up through the dirt.
- The shoot grows taller and taller until it is taller than Leo.
- At last a big golden flower opens wide to face the sun, and Leo smiles and says he wants to plant ten more.
