What it does at each step

Writes and checks

Plans chapters for the length you pick, writes a hook, a mid-video re-hook and open loops that close at the end. The fact-check searches the web for dates, numbers and names and fixes errors before anything is voiced.

Keeps the look consistent

The storyboard keeps characters and places the same across hundreds of frames. Images come out in your channel’s style, and the render adds slow camera moves, removes generator watermarks and levels audio to YouTube loudness. Add your own storyboard rules or paste your own prompt.

Packages for clicks

Five title options, a description with chapters, tags, and three thumbnail concepts built around a single curiosity gap. Ask for new concepts until one works.

Channels in 12 languages

Describe your niche in a sentence and Campsis Studio builds a channel profile: voice, language, script style, image style and thumbnail colors. Run several channels from one app.

English, French, German, Spanish, Italian, Portuguese, Polish, Ukrainian, Russian, Dutch, Turkish, Japanese.

Questions

Is there a free trial?: Yes, 7 days of full access after you create an account in the app. No card is needed.
Does the subscription include AI usage?: No. You connect your own accounts (an AI for text of your choice, Lumean and FastGen) and pay them directly. A typical 20-minute video costs a few dollars in total across all three.
Does it work with ChatGPT or Gemini?: Yes. For text you can choose Claude, ChatGPT, Gemini, Grok, DeepSeek or OpenRouter. The fact-check searches the web with Claude, ChatGPT, Gemini and OpenRouter. The studio is tuned best for Claude.
How long can a video be?: Any length from 1 to 90 minutes. The script adapts: a short video is one tight piece, a long one gets extra re-hooks to keep viewers watching.
Who owns the videos?: You do. Everything is generated on your accounts and saved on your computer. You are responsible for following YouTube’s policies, including disclosure of AI-generated content where it applies.
Windows shows “Windows protected your PC”. Is that normal?: Yes. It appears for new apps that Windows doesn’t know yet. Click “More info”, then “Run anyway”.
Is there a Mac version?: Not yet. Windows only for now.
How do I cancel?: Use the “Manage subscription” link in your Creem receipt or go to creem.io/my-orders. Access continues until the end of the paid period.
