How to Find a Saas Explainer Video Platform Free

If you’re searching “SaaS explainer video platform free”, chances are you’re a SaaS founder, marketer or content creator who is frustrated by the expensive and time-consuming nature of traditional video production, and you’re looking for a more efficient alternative.

Explainer videos are supposed to be clear, engaging and highlight the selling point of your product. However, most SaaS explainer videos fall short of these expectations.

If you want to avoid the trap of spending all your money and time on overly corporate, stuffy explainer videos that don’t actually convert, this article is for you. Here, we’ll explain why traditional SaaS explainer videos often fall flat and present a new alternative — AI agents.

We’ll also compare three of the best AI video platforms: Argil, Veo 3 and HeyGen and share the secret to creating high-converting explainer content.

Why Does Traditional Saas Explainer Content Fail?

When you’re searching “SaaS explainer video platform free”, you should keep in mind that most traditional explainer videos fail to convert, despite how crucial they are for tech and SaaS brands.

According to James Bryant in Forbes (Co-founder of Venture Videos), “In the competitive tech market, customers need to understand the value of products and services in a way that is easy to understand.”

However, startup founders and solo content creators don’t always have the budget, resources or technical skills for professional video production, so they end up turning to cheap AI video tools to try to solve their problems. The result is usually generic, stiff and overly corporate video content with robotic AI voiceover and fake-looking animation.

In the B2B SaaS world, people want to buy from people – buyers want to know if they can trust you and your product. So if your videos feel inauthentic or sterile, your brand won’t come across as trustworthy or legitimate. This is a huge stumbling block for creators trying to win over audiences with explainer videos without breaking the bank.

Hiring video agencies or freelance professionals can cost thousands of dollars, and it can take weeks to script, film, edit and produce the final product. And then, if you want to make changes or update a feature demo, you’ll need to start over from the beginning.

With all this in mind, it makes sense that so many SaaS founders and marketers are searching for “Saas explainer video platform free.” Luckily, AI agents like Argil might just be the solution.

How Can AI Agents Help Founders Create SaaS Explainer Videos?

AI video platforms are hugely popular among marketers, content creators and entrepreneurs. Tools like Synthesia and Runway offer a simple solution to a complex problem – using generative technology to streamline video creation.

Instead of spending thousands of dollars on a production team, anyone can sign up and create videos from text prompts, scripts, ideas and images.

The problem is, many of these platforms offer only simple video generation, with no nuance or personality. This is where AI agents come in.

AI agents (like Argil) are more than just video generators — they act as co-pilots in your content journey, sort of like a virtual assistant. Not only will they turn your ideas into fully-fledged scripts, but they’ll also handle every part of the video creation process, from B-roll to background music and captions, completely autonomously.

The difference between a simple video generator and an AI agent is this:

Video generators will turn your ideas or prompts into videos, which you will then need to edit and export manually. They usually offer very little customization, and you’ll be limited to basic templates and generic AI voices.

AI video agents will provide a full, autonomous content workflow – handling everything from script creation to editing and distribution. You’ll have full creative control despite the automation, with options to fine-tune everything from background details, voice synthesis and avatar lip-sync. You’ll also be able to easily A/B test different videos, and your AI agent will learn from past performance data to help you iterate.

So, it’s not quite as simple as Googling “Saas explainer video platform free” and then using the first free video generator you stumble across. If you want real results and explainer videos that look and sound professional, then you need to be using an AI video agent.

What’s the Best SaaS Explainer Video Platform Free & Paid?

Argil

Free trial, paid plans start at $39 per month.

Argil stands out as the best Saas explainer video platform for founders because of one secret weapon: AI clones and avatars. If you’re looking for the best Saas explainer video platform free, you might have hit the jackpot.

Not only is our tool versatile, flexible and user-friendly, but it also allows you to create a digital clone of yourself using a short sample video of you speaking. These authentic digital representatives will help you make connections to your audience without spending hours in front of a video camera.

Our avatars are extremely lifelike and can perform scripts in over 50 languages. They can also hold, wear and demo branded products thanks to our new product showcase feature.

Ideal for onboarding, demo, product and user education videos, Argil provides a fully agentic experience — handling everything from scripting to editing and distribution.

Veo 3

1 month limited free trial. Included in Google AI Pro plans from $25 per month.

Veo 3 is Google’s latest video generation model. It is a great option for polished marketing videos, allowing users to create scenes with animated templates, stock footage and AI voiceover.

While Veo 3 doesn’t offer AI avatars and clones like Argil, it is a valuable tool for SaaS brands looking to cultivate a more cinematic or animated look for their marketing and explainer videos. The platform offers clean, modern visuals and strong customization options, so it is perfect for landing page videos or pitch decks.

Compared to Argil, Veo 3 provides a less “human” presence, and it doesn’t offer as much in terms of scalability or batch-produced content.

HeyGen

Limited free plan (3 videos per month). Creator plan starts at $29 per month with limited features, scaling up to Team and Enterprise solutions.

Another powerful SaaS explainer video platform free, HeyGen is great for more corporate-looking avatar-based videos and offers a diverse range of AI presenters and avatars. HeyGen offers a large library of templates and AI presenters, with advanced language translation and dubbing.

However, avatars feel a bit more robotic and less personal than Argil, which could impact audience trust. Videos also have more of a corporate feel, so may not be suited to all brands and niches.
