Synthesia: An overview of the AI video generator for 2025

Let’s be honest, making a video is a whole production. You’ve got to find a studio, deal with actors, and then sink hours into editing. It’s slow, it costs a lot, and that’s why companies are looking for an easier way. AI video generators are popping up everywhere to help with training, marketing, and just getting messages out internally.

You’ve probably heard of Synthesia. It’s one of the big players, promising you can make slick-looking videos with just a text script, no cameras, no mics. Sounds great, but is it really that simple?

We’re going to dig into what Synthesia actually offers. We’ll look at its features, who’s using it, what it costs, and where it falls short. By the end, you should have a solid idea of whether it’s the right tool for your team.

What is Synthesia?

At its core, Synthesia is an AI platform that turns your text scripts into videos starring realistic AI presenters. You feed it a script, and it generates a video with a digital person reading it out loud, complete with a voiceover and synced lip movements. The final product is a polished video you can use pretty much anywhere.

The main selling point is making video production faster and cheaper than doing it the old-fashioned way. Need to change a sentence in a training video? Instead of a full-blown reshoot, you just tweak the script, and Synthesia generates a new version in a few minutes.

Key features of Synthesia

So, what’s actually inside Synthesia? The platform is packed with features meant to make video creation less of a chore. Let’s get into the main ones.

AI avatars and voiceovers

The first thing you’ll notice is the library of over 200 stock AI avatars. They cover a good range of ethnicities and ages. If you’ve got the budget for a pricier plan, you can even make a "digital twin" of yourself or someone on your team. This is great for companies that want to keep their branding consistent across different regions, especially since it supports over 140 languages.

But here’s the thing, the quality isn’t always perfect. <quote text="you'll see a lot of talk about the "uncanny valley." The avatars look almost real, but something’s just a little off. For some people, that can be pretty distracting, and they end up focusing more on the slightly weird digital person than on what's actually being said." sourceIcon="https://www.iconpacks.net/icons/2/free-reddit-logo-icon-2436-thumb.png" sourceName="Reddit" sourceLink="https://www.reddit.com/r/instructionaldesign/comments/1k0bhoz/what_are_your_experiences_using_synthesia/">

Video creation and templates

Getting a video made is pretty simple. You write (or paste in) your script, pick from a library of over 60 templates, select an avatar, and hit the "generate" button. The templates are handy for common things like training modules or company updates.

There’s also a feature that lets you import a PowerPoint presentation and have Synthesia try to convert it into a video. It’s a nice idea, but in practice, it usually needs a lot of manual adjustment to look right. It can be a decent starting point, but it’s not the one-click magic wand you might be hoping for.

Localization and collaboration tools

One of Synthesia’s most impressive features is its "1-click translation." You can take a video you’ve already made and have it automatically create versions for other languages, matching the voice and lip movements to the new script. For any team working globally, this can save a massive amount of time on localizing training content.

But there’s a huge catch. This feature is only available on their custom-priced Enterprise plan. For smaller businesses or teams on a tighter budget, this powerful tool is locked behind a paywall that’s likely out of reach. On a simpler note, the platform does include basic collaboration features like shared workspaces and commenting, which help teams work together on scripts and storyboards.

Common use cases for Synthesia

Synthesia is pretty versatile, so you’ll find it being used in a few different ways across a company. Here are the most popular spots.

Employee training and onboarding

This is a big one. Companies use Synthesia for everything from compliance training and HR policies to rolling out new software. The real win here is how easy it is to keep content up-to-date. When a process changes, you don’t need to call the video crew back in. You just open the project, edit the text, and generate an updated video. It can then be dropped right back into your learning management system (LMS).

Sales enablement and marketing

Sales and marketing folks are using Synthesia to churn out product demos, personalized videos for outreach, and quick clips for social media. It lets them create a lot of targeted content without getting stuck in the weeds of traditional video production. This frees them up to spend more time on strategy instead of editing timelines.

A look at Synthesia’s limitations and costs

While Synthesia can do some cool things, it’s not without its downsides. Before you jump in, it’s worth thinking about some of the practical challenges.

The challenge with video: Finding quick answers

Okay, so Synthesia is good at making videos. But let’s think about how people actually use information. When a support agent is on a call or an employee needs an answer right now, the last thing they want to do is watch a video. They’ll have to scrub through it, guess where the right part is, and hope they land on the right timestamp. It’s just not practical for quick answers.

Making the content is one thing, but making it useful and easy to find is a whole different ballgame.

This video provides a short walk-through of how to create an AI video quickly using Synthesia.

This is where the whole approach of video-first knowledge starts to show its cracks. Instead of making your team hunt through video timelines, what if they could just… ask a question and get an answer?

A tool like eesel AI is built for this exact problem. It hooks into the places you already keep your information, like the Google Docs or Confluence pages where your video scripts live, and turns it all into a conversational brain for your company. Your team can ask questions directly in Slack or your helpdesk and get a straight answer in seconds, not a link to a 10-minute video.

The hidden cost of essential features

As we touched on earlier, some of Synthesia’s best features are gatekept in its most expensive plan. If you’re a larger company that needs things like 1-click translation, unlimited video creation, or SCORM exports to work with your LMS, you have no choice but to go for the Enterprise plan.

This means you’re looking at custom pricing, which often translates to a big, unpredictable bill. That’s a tough pill to swallow for teams that need to keep their budgets in check. It’s a completely different model from a tool like eesel AI, which offers clear and predictable pricing. With eesel AI, you know exactly what you’re paying based on usage, and you’re never charged per answer. Your costs don’t suddenly spike just because your team is actively using it.

Synthesia pricing in 2025

Here’s a simple breakdown of Synthesia’s pricing plans, based on the info on their site.

Plan	Monthly Price (Billed Monthly)	Key Features	Best For
Free	$0	Up to 3 minutes of video/month, 9 AI Avatars.	Individuals just wanting to try it out.

Enterprise	Custom	Unlimited video minutes, 230+ avatars, 1-click translation, SCORM export, SSO.	Large companies with complex training and security needs.

The verdict: Is Synthesia the right tool for you?

Synthesia can be a good tool if you need to create a lot of simple, template-based videos and have the budget for the higher-tier plans. For standardized training content or quick marketing clips where you just need to get information out there, it can definitely speed things up.

But you can’t overlook the drawbacks. The "uncanny valley" problem is real and can hurt viewer engagement. The most useful features for scaling are locked away in the expensive Enterprise plan. And most importantly, video just isn’t a great format for getting quick, specific answers.
