Episode 1 · Pexo Launches Conversational AI Video Agent for Vibe-Editing (2026-09-21, 5 posts)

Startup Pexo has released an "AI video agent" built around making and editing videos through conversation, much like vibe coding: users describe an idea in natural language and supply reference material, and Pexo handles scriptwriting, shot planning, and creative direction, ultimately delivering a finished video with voiceover, music, subtitles, and motion graphics. The company says its demo video was generated entirely by Pexo.

Confirmed

  • Flexible inputs: as @Arindam1729 and @SimplyAnnisa describe, Pexo can start from a URL, PDF, image, audio, or just an idea, automatically planning the script and storyboard before producing the final video.
  • The interaction model is the core selling point: to change visuals, users annotate directly on the video and leave comments like in Google Docs, iterating via chat—no complex prompts or traditional editing timelines to learn.
  • Multiple reposters (@aftahiai, @heyabusiddik) confirmed that the visuals, motion effects, music, subtitles, and voiceover in the demo were all generated by Pexo; @Arindam1729 says the output can be published directly to TikTok/YouTube and other platforms.

Why it matters

  • Pexo shifts video production from timeline editing and prompt engineering to a conversational workflow, extending the "AI agent + natural language iteration" product philosophy and lowering the barrier for non-professional users; if it works as demonstrated, it could disrupt short-form marketing content tools.
