10 Best AI Video Generators in 2025

What Are AI Video Tools?

AI video tools use artificial intelligence to automate or enhance video creation/editing. They can generate videos from text prompts, images, or audio, and edit existing content with effects, transitions, and avatars.

Categories of AI Video Tools

1. AI Video Generators

Create entire videos from scratch using text, images, or audio.

Examples: Runway Gen‑4, Google Veo 3, Kling AI, Pika Labs.

  • Runway Gen‑4: Generates highly consistent, cinematic videos with realistic motion and story adherence
  • Google Veo 3: Google’s DeepMind model now supports native audio generation—dialogue, sound‐effects, ambient noise—all in one
  • Kling 2.1: Excels at image-to-video realism and motion coherence, seen as a challenger to Veo 3
  • Pika Labs: Fast, accessible video clips (3–4 sec), ideal for creative freedom and quick outputs

2. AI Video Editors

Enhance or automate editing—adding transitions, subtitles, effects.

  • Adobe Firefly: Text-to-video for B-roll and assets.
  • Descript: Edit videos by simply editing the transcript.

3. AI Video Presenters / Avatars

Generate realistic avatars or presenters.

  • Synthesia & HeyGen: Create avatar-led narration and training videos.
