Free AI Explainer Video Generator

An explainer video is a short and engaging piece of content that clearly presents a company’s product, service, or idea. They are a common part of sales and marketing strategies, and you will often see them on landing pages, social media, and inside promotional campaigns. The goal is to capture attention, communicate a message, and drive engagement.

Start by thinking about the goal of your video and the message you want to communicate. Once you have that, the creation process usually involves four simple steps:

1. Write a video script: Plan exactly what you want to say and use the script to structure the flow of your video.
2. Use a video tool to create the video: Instead of hiring a production company, use a video maker to simplify the process. A tool like Synthesia lets you create explainer videos from text with realistic AI avatars, which saves time and money.
3. Review and refine: Watch the video to make sure the message is clear and aligned with your goal. Adjust text, templates, visuals, or sound if needed.
4. Publish and track performance: If something needs to change later, simply return to your project in Synthesia and make quick edits to create an updated version. Traditional production would take far more time and budget.

A strong explainer video grabs attention right away, so the first few seconds matter. Try these tips:

• Get to the point: Start by outlining the problem your product or service solves and introduce it as the solution.
• Keep your message clear: Avoid confusing or overly complex language. Use simple, engaging wording to help viewers understand the idea quickly.
• Make it visually appealing: Use visuals and styles that match your brand and keep everything consistent. Viewers should enjoy both the message and the way it looks. Often, less is more.

Creating an explainer video in Synthesia typically takes about 10 minutes from start to finish. The video itself is generated only a few minutes after you click Generate. The speed comes from the simplicity of the workflow. You type or paste your script, choose an AI presenter, pick a template, and add visuals. Traditional production would require planning, filming, editing, and voiceover work, which can take weeks.

This speed becomes even more valuable when you need multiple versions or want to update existing content. Because everything is built from text, you can change your script, swap presenters, or adjust visuals and generate a new version in minutes. It makes it practical to create personalized explainer videos at scale or react quickly to business changes.

Yes. Synthesia includes an AI screen recorder that lets you capture your screen inside the platform. You can record software demos, show digital products, walk through slides, and then add these recordings directly into your video. You can also trim, crop, and edit your screencasts without using separate editing tools.

This feature is especially useful for product demos, tutorials, and training content. When you combine screen recordings with an AI presenter who explains what is happening on screen, the result is a more engaging and informative video.

Yes. One of the biggest advantages of Synthesia is the ability to return to any project and make changes at any time. Because your video is built from a script and modular elements, you can update the narration, change visuals, replace screen recordings, or switch presenters. Just open the project, make your edits, and generate a new version.

This flexibility keeps your content fresh. When product features change, messaging evolves, or information needs correcting, you can update your video in minutes instead of scheduling new shoots. It ensures your explainer videos stay relevant and useful over the long term.
