AI influencer video generator: one character, a new video every day
Cast is an AI influencer video generator for phones: describe a character once (15 credits for four looks to pick from), then type one line per video and get a vertical clip of that same character in your feed. A 5-second Standard video costs 52 credits, and your first one is free with no sign-up.
How an AI influencer works in Cast
- Design the character once. Describe them in a sentence (age range, face, hair, outfit, attitude) and pick a style. Cast draws four looks with Midjourney v8.2 for 15 credits; tap the one you want.
- Pick a format and stick to it. A recurring format is what makes an account feel like a person. The phone-POV livestream is the one that has worked best for us.
- One line per video. “reads her hate mail live at breakfast”. Cast writes the full shot-by-shot prompt and keeps the face from the reference.
- Post it. Download or share from your private feed.
Case study: Malfoid
Malfoid is our own AI influencer: a snobby boarding-school girl who livestreams her life. We started posting her on 2026-10-13 on YouTube, TikTok and Instagram, with dance trends, storytimes and tutorials. She is also the free character pack in Cast, so you can put her in your own videos.

When Cast is not the right tool
- Scheduling or auto-posting to social accounts. Cast only makes the videos.
- A digital twin of a real person or lip-sync to your own recorded voice.
- Long-form content; clips are 15 seconds at most.
- Characters based on real people or on existing franchises. The video model blocks look-alikes of famous faces, and Cast strips franchise names from prompts.

Quick answers
- How much does it cost to post an AI influencer video every day with Cast?
- Thirty 5-second Standard videos a month cost 1,560 credits. The Creator pack ($14.99, 1,500 credits) covers about 28 of them; Premium ($19.99/month, 2,000 credits) covers about 38.
- Does the character stay the same between videos?
- Yes. The look you pick becomes the reference image for every video, and its written description is sent with it each time.
- Can Cast post to TikTok or Instagram for me?
- No. Cast makes the video; you download or share it from your feed and post it yourself.
