Knowcast: AI Explainer Video Generator

Knowcast is a web app that automates the full explainer video pipeline. You give it a topic, it breaks the concept into a logical sequence, picks or generates images for each step, adds captions, and exports a finished video. No timeline editing, no voiceover recording setup, no design skills needed.

The tool sits in a growing category of text-to-video generators, but its specific angle is educational clarity. It is built around structured explanation rather than cinematic output, which makes it more useful for training, onboarding, and product education than for brand storytelling.

Pricing runs from a free tier up to paid plans at $20, $60, and $200 per month, so a solo operator or small team can test it without commitment. The main constraint is that the visual style is AI-generated imagery assembled from a storyboard, so you get consistency in structure but limited control over exact visuals.

How teams can use it

HR manager

What for: Create short onboarding explainer videos for new hires covering company policies or benefits

Outcome: New employees watch a clear two-minute video explaining, for example, how to submit expenses or book time off, reducing repeat questions to HR

Build it in 4 steps:

1. Go to knowcast.app and start a free account.
2. Type a prompt such as 'explain our expense reimbursement process in 5 steps'.
3. Review the storyboard Knowcast generates and edit any step that does not match your actual process.
4. Export the video and upload it to your company intranet or share the link in the onboarding email.

Where it gets complex: If you need the video to show actual screenshots of your internal software, a specialist will need to record and edit those separately.

Marketing manager

What for: Produce short educational social videos that explain a product feature or industry concept to build audience trust

Outcome: A ready-to-post 60-second explainer for TikTok or Instagram Reels that breaks down one concept clearly, published in under an hour

Build it in 4 steps:

1. Write a one-sentence topic, for example 'how does compound interest work'.
2. Paste it into Knowcast and let it generate a storyboard.
3. Swap out any scene descriptions that feel off-brand by editing the text prompts.
4. Download the video and add your logo or a call to action using Canva before posting.

Where it gets complex: Custom voiceover in a specific brand voice or language other than the defaults will need a separate tool or a voice actor.

Operations lead

What for: Document a standard operating procedure as a short video so staff can follow it without reading a long text document

Outcome: A step-by-step process video that new or temporary staff can watch before starting a task, cutting training time and errors

Build it in 4 steps:

1. List the steps of the procedure in plain text, for example the steps to open and close the register.
2. Paste the list into Knowcast as the prompt.
3. Review each scene in the storyboard and adjust the descriptions to match your actual steps.
4. Export and save the video to a shared folder or link it in your team chat.

Where it gets complex: If the procedure involves physical equipment or location-specific details, you may need to film a short real-world clip and splice it in using a basic editor.

Small business owner

What for: Create a product explainer video for a website or product page without hiring a videographer

Outcome: A polished explainer video that describes what the product does and who it is for, ready to embed on a landing page

Build it in 4 steps:

1. Write two to three sentences describing your product and the problem it solves.
2. Enter them as the prompt in Knowcast and generate the storyboard.
3. Edit any scene that misrepresents the product by rewriting the scene description.
4. Export the video and embed it on your website using your site builder's video block.

Where it gets complex: If you want real product footage or customer testimonials included, those clips need to be recorded and edited in separately.

One caution

Visual output is AI-generated imagery, so you cannot use your own brand photos or product screenshots inside the video without workarounds, which limits on-brand accuracy for product demos.
