AI Auto Video Generator: Topic In, Video Out
An AI auto video generator makes the whole video from one topic: script, scenes, voice, captions and the render. Reviral's text-to-video creator does each step for you, and a 15-second video at its default settings costs 244 credits (~$3.04); Auto-Mode can repeat it on a daily or weekly schedule from a list of topics.

- One topic in, a finished video out
- Script, scenes, voiceover and captions done for you
- Optional music, 30 script languages
- Auto-Mode: one new video a day or a week
What the generator does automatically
You type a topic, such as five ways to keep basil alive. Reviral writes a short script, splits it into scenes, finds or generates a visual for each scene, reads the script in the voice you choose, times animated captions to the words, adds music if you turn it on, and renders the file.
You choose the shape (9:16, 16:9 or 1:1), the voice and the visual style before you start; everything after that runs on its own.
Auto-Mode: videos on a schedule
Auto-Mode takes a list of topics, one per line, and makes one video per day or one per week, working down the list and starting again when it reaches the end. Ten topics on a daily schedule give ten days of videos.
What it costs
A 15-second video at the creator's default settings costs 244 credits (~$3.04). Longer videos and other visual types change the price; the button shows the exact number before you render.
Sign-up gives 100 free credits with no card, and the exact charge shows before anything renders.

Frequently asked questions
- Can AI auto generate video content?
- Yes. Type a topic and Reviral generates the script, scenes, voiceover, captions and optional music, then renders the video; a 15-second video costs 244 credits (~$3.04) at the default settings.
- Can it post a new video every day?
- Auto-Mode makes one video per day or per week from your topic list. Posting to social accounts is a separate step from the Publish page.
- Do I have to write a script?
- No. The generator writes it from your topic. If you already have a script, the script-to-video tool keeps each of your lines word for word instead.
