FAQ
AI explainer video maker questions
What is an AI explainer video maker?+
An AI explainer video maker turns text or documents into a narrated, animated video automatically. With Knowlify, you type a prompt or upload a doc and the AI writes the script, builds a scene-by-scene storyboard, generates a voiceover, and animates the scenes. No editing software, designers, or production crew required.
Is the AI explainer video maker free?+
You can start free. Type a prompt or upload a document above and click "Create video" to open the Knowlify studio, generate your first explainer video, and edit the script before rendering. Paid plans add more credits, longer videos, and team features.
How do I make an AI explainer video?+
Three steps: (1) type a prompt or upload a PDF, slide deck, or blog post; (2) the AI generates a narrated script and storyboard; (3) edit any scene, choose a style and voice, apply your brand, and export. Most videos are ready in minutes.
How is Knowlify different from Synthesia or Pictory?+
Synthesia is avatar-first and Pictory is stock-footage-first. Knowlify is built around turning your documents into fully animated, on-brand scenes, with optional AI avatars, voice cloning, a 40+ style library, brand kit, and the ability to edit by chatting in plain English. It is the most complete doc-to-video workflow.
What can I upload to create a video?+
PDFs, Word docs, Google Docs, slide decks, blog posts, outlines, and plain text. The AI reads your content and turns it into a structured explainer video with a scene for each key idea.
Can I add my brand colors, logo, and a presenter?+
Yes. The brand kit fetches colors straight from your website or extracts a palette from an image, and applies your logo and colors across every scene. You can also add an AI avatar host or upload a photo to create a custom digital twin presenter.
Can I edit the AI explainer video after it is made?+
Yes. Edit the script line by line, tweak per-scene motion and first-frame prompts, or just chat with the AI in plain English ("make scene 2 more dramatic"). Re-render instantly, changing a sentence instead of reworking a hundred keyframes.
What languages and voices are supported?+
Knowlify supports a wide range of natural AI narration voices and accents, and you can clone your own voice or add a custom voice ID so videos sound like your brand in your audience’s language.
Can I use the videos commercially?+
Yes. Videos you create are yours to use across marketing, training, onboarding, sales, and internal communications. Teams use Knowlify to build entire video libraries that keep growing.
How long does it take to make an explainer video?+
Minutes. Knowlify generates the full narrated, animated video automatically, so you skip the weeks of work a traditional video editor or agency would need.
