AI influencer video generator: one character, a new video every day
Cast is an AI influencer video generator for phones: describe a character once (1 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 1 credits; live agent renders require purchased credits.
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 1 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 TikTok and Instagram, with dance trends, storytimes and tutorials. In Cast you play her stories card by card.

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 30 credits. The Creator pack ($4.99, 32 credits) covers about 32 of them; Premium ($19.99/month, 120 credits) covers about 60.
- 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.
