I tested 6 top Synthesia alternatives in 2025 for AI training videos

Synthesia is a pretty slick tool for making videos with AI avatars. It's great if you need to whip up a big company announcement or a quick marketing clip. But when I was tasked with creating product training and support content that could actually scale, I hit a wall. A talking head video just wasn't cutting it. Our users needed to see the product in action and get their questions answered, not just watch another presentation.

That realization sent me down a rabbit hole of testing the best Synthesia alternatives on the market. I wasn't just looking for another tool that could generate an AI presenter. I wanted to find something that solved the real problem: how do you create genuinely helpful training and support content that people can use and that you can easily keep up to date?

Here’s what I learned along the way.

What are AI video generators and why search for Synthesia alternatives?

At their core, AI video generators are tools that spin up videos from a text script. You type what you want your presenter to say, and the platform uses an AI avatar, a text-to-speech voice, and some background templates to bring it to life. They're mostly used for marketing content, internal comms, and some light training where having a presenter is the main goal.

So, why bother looking for an alternative? Well, as cool as they are, I ran into a few common issues.

• The avatars get old fast. After you've seen a few, the AI presenters can start to feel a bit robotic and repetitive. It can make your content feel a little soulless over time.

• The price can be steep. The costs can really climb, especially if you're making a lot of videos. The price tag doesn't always feel like it matches the creative limitations you're working with.

• And the biggest problem: they can't actually show your product. An AI presenter is great for telling you something, but it can't walk you through a complicated process, show you exactly where to click, or give you the kind of hands-on guidance that's essential for real product training.

How I chose the best Synthesia alternatives

To find tools that actually solve these problems, I set up a few simple criteria to judge them by. No fluff, just what really matters for creating helpful content.

• Did it fit my use case? Could it handle complex product demos and interactive support, or was it just another presenter-in-a-box?

• Could it scale? How easy was it to not just create content, but more importantly, to update it when our product inevitably changed?

• Was it engaging? Did it offer anything beyond just watching a video to help people actually learn and solve problems?

• How fast could I get going? Could I sign up and start making useful stuff right away, or was I stuck waiting for a sales demo?

• Was the pricing clear? I wanted to see straightforward pricing that made sense for the value I was getting.

A closer look at the 6 best Synthesia alternatives

Here’s my breakdown of each tool I tested, warts and all.

1. eesel AI

I quickly realized that eesel AI plays a completely different game. While Synthesia helps you create videos that explain things, eesel builds an AI agent that just solves the problem directly. Instead of forcing a user to search through a video library, eesel gives them an instant, personalized answer through a chatbot on your website or an internal Q&A bot for your team.

It’s a total shift from making people watch content to letting them actively solve their own problems. It's built for teams that want to automate their support and offer training on demand, right inside the apps they already use, like Slack or Zendesk.

What I liked:

• You can get started in minutes. The setup is genuinely self-serve. I was able to connect our knowledge sources and launch a test agent without a single sales call.

• It pulls from all your existing knowledge. It learns from your old support tickets, help articles, Confluence pages, and Google Docs to give answers that are actually accurate and specific to your business.

• It's fully interactive. People don't just watch; they ask questions and get real answers. The AI can even take action, like looking up an order status or creating a new support ticket.

• You can test it with your real data. The simulation mode was what really sold me. You can test the AI on thousands of your past support tickets to see exactly how it would have performed and what its resolution rate would be before you let it talk to a single customer.

What I didn't like:

• It's not a video creation tool, so if you absolutely need a video, this isn't it. It's an AI agent platform that often makes videos unnecessary in the first place.

• The starting price is higher, which is understandable since it's focused on automating business processes and delivering a measurable return.

Pricing: eesel AI's pricing starts with the Team plan at $299 a month, or $239 a month if you pay annually. That gets you 1,000 AI interactions per month, training on your website and docs, and key integrations. The Business plan at $799 a month ($639 annually) adds the ability to train on past helpdesk tickets and let the AI take actions.

2. HeyGen

HeyGen is probably the closest thing you'll find to a direct Synthesia competitor. If your heart is set on making videos with AI presenters, this is the first place you should look. It has a well-deserved reputation for its high-quality, realistic-looking avatars and a huge library of voices.

For teams that are all-in on using AI presenters for marketing and promos, HeyGen is a seriously powerful platform.

What I liked:

• The avatar realism and lip-syncing are top-notch.

• There's a massive library of over 1,000 stock avatars and more than 1,000 AI voices to choose from.

• It has some cool extra features, like voice cloning and a ton of customizable video templates.

What I didn't like:

• It has the same big weakness as Synthesia: it can't show your product in action or offer any real interactivity.

• It's really geared toward that presenter-style video, which makes it less useful for creating deep, technical training content.

Pricing: HeyGen has a free plan that lets you make 3 watermarked videos a month. Paid plans start with the Creator plan at $29 a month ($24/mo annually), which gives you unlimited videos and removes the watermark. The Team plan starts at $39 per seat per month and adds 4K exports and collaboration tools.

3. Clueso

Clueso is designed for people who need to show their product, not just talk about it. It was a breath of fresh air. You give it a raw screen recording, and its AI automatically polishes it into a professional-looking video and a step-by-step written guide.

This tool directly tackles the whole "show, don't tell" issue that avatar generators can't solve. If you're making product tutorials, onboarding guides, or help docs, Clueso is a fantastic option.

What I liked:

• It automatically adds smart zoom effects and highlights to your recordings, making them look way more professional without any extra effort.

• It generates both a video and a written article from one recording, which is a massive time-saver.

• Updating content is super easy. If your UI changes, you can just edit that one step instead of re-recording the entire video.

What I didn't like:

• No AI avatars. If you need a human-like presenter, this isn't the tool for you.

• It’s laser-focused on screen-based content, so it's not as versatile for other types of videos.

Pricing: Clueso offers a 7-day free trial. The paid Starter plan is $120 a month for 2 users and includes 6 hours of video exports per year. The Growth plan at $200 a month for 4 users bumps that up to 12 hours.

4. DeepBrain AI (AI Studios)

DeepBrain AI is all about creating hyper-realistic, TV-quality AI avatars. This is the platform for big companies that need the absolute highest level of polish for corporate news, official announcements, or financial updates.

When brand image is everything, DeepBrain AI delivers a level of realism that’s tough to match. They're clearly focused on large organizations that need a powerful and secure solution.

What I liked:

• The avatar quality is truly at a broadcast level, with natural-looking hand gestures and movements.

• They have strong security and compliance features, like GDPR and ISO certifications.

• You can create a custom avatar to serve as a consistent digital spokesperson for your brand.

What I didn't like:

• The whole experience is geared toward enterprise clients. It's not a self-serve tool you can just sign up for and start using immediately.

• It feels less flexible for creative projects or videos you need to produce quickly.

Pricing: While DeepBrain AI is aimed at enterprise, it does have plans for smaller teams. The Personal plan is $24 a month (paid annually) for unlimited videos. The Team plan starts at $55 a month per seat and adds 4K export and premium avatars. There's also a free plan for 3 watermarked videos.

5. Colossyan

If your main job is creating training courses, Colossyan is one to put on your list. It's an AI video tool that's packed with features specifically for educational content, like building scenario-based lessons or turning a PowerPoint deck into a video.

It does a nice job of bridging the gap between a standard AI video generator and a full-blown e-learning platform, offering more interactivity than most of the competition.

What I liked:

• It has built-in features for adding quizzes and interactive, branching scenarios to your videos.

• It supports SCORM exports, so it plays nicely with most Learning Management Systems (LMS).

• You can create conversations between multiple AI avatars in the same video, which is a neat touch.

What I didn't like:

• The avatars are generally not as realistic as what you'll find on HeyGen or DeepBrain AI.

• I noticed that the video rendering times could be a little slow compared to other tools.

Pricing: Colossyan has a free 14-day trial. The Starter plan is $27 a month ($19/mo annually) for 15 minutes of video. The Business plan at $88 a month ($70/mo annually) gives you unlimited video minutes and access to the interactive features.

6. Veed.io

Veed.io is a different beast altogether. It’s a powerful, web-based video editor that also happens to have a bunch of AI features, including avatars and text-to-speech. It’s the perfect hybrid for teams that find the pure AI generators too restrictive and want more hands-on creative control.

If you need timeline-based editing, custom transitions, and advanced effects alongside the convenience of AI, this is a great choice.

What I liked:

• It combines a professional-grade video editor with AI tools in one convenient package.

• The automatic subtitle generation and background removal tools are excellent.

• It's versatile enough to handle everything from slick marketing videos to detailed training tutorials.

What I didn't like:

• It has a steeper learning curve than the simpler, AI-only platforms.

• The AI avatar feature feels more like an add-on than the main event.

Pricing: Veed.io offers a free plan with watermarked videos. Paid plans start with the Lite plan at $12 per editor per month (billed annually), which removes the watermark. The Pro plan at $29 per editor per month (billed annually) unlocks more advanced AI tools.

How to choose the right Synthesia alternatives for your team

So, how do you pick one? After all this testing, it really came down to one question for me: "What is this content actually supposed to do?"

• Just need slick marketing videos with presenters? Then tools like HeyGen or DeepBrain AI are probably your best bet.

• Need to create product tutorials and docs that actually show your software? You should be looking at something like Clueso or Veed.io.

• But if your real goal is to provide fast, scalable training and instant support, then you should think beyond video. A platform like eesel AI gives you a more direct path by providing interactive answers and automating resolutions. It saves your team a ton of time and gives your users the immediate help they're looking for.

The future of Synthesia alternatives is interactive, not just passive

AI video generators like Synthesia are impressive pieces of tech, but they're still a very passive way to deliver information. After going through this whole process, I'm convinced that when it comes to effective training and support, the future is interactive.

Instead of pouring your budget into a library of videos that will be out of date in six months, it might be worth looking at a solution that learns from your company's knowledge in real-time and empowers people to solve their own problems.
