Four categories of AI video tools
AI video generation tools split into four categories by mechanism and specialty. The right question isn't "which tool is best?" but "which category fits my use case?".
① Text-to-video (Fliki / Pictory)
Paste in articles or scripts and the tool assembles narration, captions and visuals into a video. Best for explainer and round-up volume. Fliki excels at multilingual narration and ease; Pictory excels at article summarization and long-form clipping.
② AI avatar (Synthesia / HeyGen)
An on-camera AI avatar reads your script. Talking-head video without a studio or cast. Synthesia leads on enterprise training and SOPs; HeyGen leads on avatar expressiveness and video translation with lip-sync.
③ Online editor (Veed)
Edit, caption and screen-record in the browser. Less about generation, more about polishing — ideal for finishing social video.
④ Generative video (Runway)
Generate the footage itself from text or images. Best for visuals you can't shoot live, or concept work. More creative, less explainer.
Five selection criteria
- Type of output: explainer / avatar / editing / footage generation — which one?
- Pricing and credits: monthly fee plus generation minutes / credits. Volume pushes you up tiers.
- Languages and Japanese quality: narration and caption quality. Sample on free plans.
- Free plan terms: watermark, export caps. Can you validate quality first?
- Operational intent (incl. affiliate): review media benefits from recurring-commission programs (e.g. Fliki).
