How it works

Three steps.
Then post.

We handle the full production stack — not just one piece. You stay in the parts that need your taste; we handle the rest.

01

You paste.

A Google Doc, Notion page, blog URL, PDF — anything you've already written. Just drop it in.

02

We make it.

We write the script, pick the voice, design every visual, add music, cut it tight. Like a director calling the shots.

03

You post.

Done in about 3 minutes. Watch it first, then export.

Made for you if

You already have the content.
We turn it into video.

Substack on Sunday,
TikTok on Monday.

You wrote it. Your readers loved it. Now publish the same idea to the 90% of your audience who won't read a 2,000-word post — without becoming a video editor.

  • Vertical (9:16) and landscape from one source
  • Your voice, your pace — not “AI corporate narrator”
  • One-click to YouTube Shorts, Reels, TikTok
  • Auto-captions in the platform's native style

Your PDF curriculum,
finally watchable.

You spent 3 months building the course. Your students keep dropping off at lesson 4 — because it's a wall of text. Give every lesson a video version. Completion rates jump.

  • Chapter-by-chapter renders from one upload
  • Add quizzes & timestamps to any video
  • Re-render when content updates — students get the new version
  • Embed on Teachable, Thinkific, Kajabi, or your own site

Independent reviews

What reviewers say
when they actually test it.

Think of it as an AI producer rather than an AI editor.

It writes the script first — then builds every visual around the story.

The production problem

Stop being the writer,
editor, designer & voice actor
all at once.

You had the idea. You did the research. You wrote the thing. You shouldn't also have to learn Premiere, hire a voice actor, design title cards, color-grade, and re-export six aspect ratios — just to publish what you already finished.

Vibeknow does all of it — for you.

Wait, what about…

vs. the other ways.

You already have options. Here's how Vibeknow stacks up — honestly.

Honest answers

What you're actually wondering.

What is VibeKnow?+

VibeKnow is an AI-powered explainer video creation platform. Simply provide text, links, PDFs, or PPT files - the AI Producer automatically handles storyboarding, visual design, narration, and background music to deliver a complete explainer video.

What input formats are supported?+

Plain text, web links, PDF documents, PPT presentations, and more. AI automatically parses the content, extracts key information, and transforms it into a video script.

How long does it take to generate a video?+

A 3-5 minute explainer video typically takes just a few minutes from input to final output. Traditional production takes 1-2 weeks - that is over 1,000x faster.

What about video quality?+

VibeKnow videos feature professional-grade visual design and AI narration. Every frame is designed by AI - not simple template filling, but genuine content-aware, frame-by-frame creation.

What scenarios is it suited for?+

Knowledge explainers, book companion videos for publishers, educational courses, social media short videos, corporate training, and product showcases. Multiple publishers and educational institutions are already using it.

How is it different from other AI video tools?+

VibeKnow focuses on 'knowledge' videos - it is not a general AI video editor. Our AI understands your content structure: data auto-becomes charts, workflows become animations, comparisons become split screens. It is an 'AI Producer', not an 'AI editing assistant'.

Can it produce videos in batch?+

Yes. This is one of VibeKnow's core strengths. Publishers can batch-generate book companion videos, enterprises can rapidly produce standardized training content, and educators can systematically output course videos.

Is there an API?+

Yes. VibeKnow offers API access for enterprises and platforms with batch video generation needs. Contact us at sales@vibeknow.com for details.
