Faceless videos for TikTok and YouTube Shorts
SeedViral makes faceless vertical videos for TikTok and YouTube Shorts: each one has an AI-written script, an AI narrator, illustrated scenes in one art style and captions timed to the narration, made on the schedule you choose.
You set the series up once, review each finished video and download it as a 1080×1920 MP4 to upload to TikTok, Shorts or Instagram Reels. SeedViral does not post for you today.
What is in each video
| Layer | What SeedViral makes | What you choose |
|---|---|---|
| Script | A short story with a hook and a payoff, written by AI for your niche | A preset niche or your own brief; optional review before generation |
| Narration | An AI narrator reads the script | The narrator voice and language |
| Visuals | Illustrated still scenes with a slow camera move | The art style, plus optional image shake or an animated opening for credits |
| Captions | Word-timed captions over the video | The caption style |
| Music | One soundtrack under the narration | A library track or no music; signed-in accounts can upload their own audio |
| Format | Vertical 1080×1920 MP4, 30–40 or 60–70 seconds | The length for the series |
Why one vertical video works on TikTok and Shorts
Both platforms are built around vertical, full-screen video. YouTube treats square or vertical videos up to three minutes long as Shorts, and SeedViral's lengths sit well inside that. The same file can go to TikTok, Shorts and Reels, so one series can feed all three.
Captions matter for faceless video because many people watch with the sound off. SeedViral burns the captions into the video in the style you pick, timed word by word to the narration, so they show on every platform without extra editing.
Niches that suit short faceless videos
Story-led topics work best when nobody is on camera. SeedViral's presets are Scary stories, History, Mythology, Historical figures, True crime, Stoic motivation, Moral stories, and you can write your own brief instead. For History, Historical figures and True crime, scripts are written from a retained public source and each scene cites it, so you can check where a claim came from before you post.
How it works
- Set up a series
Pick a niche, narrator and language, soundtrack, art style, captions and effects, then choose the length and how often a new video is made. Setup is free and needs no card.
- Subscribe for that series
Each subscription funds one series. Plans: Hobby (3 videos a week, $29 a month), Daily (1 video a day, $59 a month), Pro (2 videos a day, $97 a month), with yearly billing available.
- Review each video
Watch the finished video, and read the script and any cited sources. You can also choose to approve each script before the video is made.
- Download and post
Download the MP4 and upload it to TikTok, Shorts or Reels with your own caption, hashtags and any AI label the platform requires. Videos stay available to download for 90 days.
Before you post: platform checklist
- Label AI content where the platform asks. As of 24 September 2026, TikTok asks creators to label AI-generated content with realistic images, audio or video; YouTube asks for disclosure of realistic altered or synthetic content.
- If you plan to monetise on YouTube, read its inauthentic-content policy: mass-produced, generic or repetitive AI videos are not eligible. Vary your topics and keep a distinct angle.
- Check facts in any video presented as true, even when sources are cited.
- Write your own title, description and hashtags for each platform.
Where SeedViral is not the right fit
- You want the tool to post to your accounts automatically: publishing is not enabled today. Check current availability.
- You need filmed footage, stock clips or fully animated scenes: SeedViral uses illustrated still scenes with camera movement.
- You want to edit on a timeline, frame by frame: SeedViral makes the video from your series choices, and changes are made by editing the script or voice and rebuilding.
Frequently asked questions
What size are SeedViral videos?
Vertical 9:16 MP4 files at 1080×1920, either 30–40 seconds or 60–70 seconds long, depending on the length you pick for the series.
Can I use the same video on TikTok, YouTube Shorts and Reels?
Yes. Each video is a vertical MP4 you download, so you can upload the same file to each platform. Follow each platform's own rules, including AI-content labels.
Does SeedViral upload to TikTok or YouTube for me?
Not today. Downloads come first and never need a social account. Publishing only switches on for a platform once that integration is approved and enabled.
Are the captions burned in?
Yes. Captions are rendered into the video in the caption style you choose, timed word by word to the narration.
Can I choose the language?
Yes. You pick the narrator and the narration language during setup, and you can preview voices before choosing.
