How to Use HeyGen and Synthesia AI for free in 2026

HeyGen and Synthesia are AI tools for creating realistic avatars, high-quality voiceovers, and video generation. Motion designers, marketers, affiliate marketers, and other professionals frequently use these platforms. Both HeyGen and Synthesia produce high-quality videos with talking heads that look as natural as possible. No film crew or professional equipment is needed. But you still have to pay for these AI tools.

In 2026, the limits on HeyGen and Synthesia’s free plans will be severely restricted. You’ll either have to pay or find a workaround. We’ll explain how to use HeyGen and Synthesia for free in 2026, what challenges users might face, and how to solve them.

Avatar IV is a digital clone of a human from the latest generation (as of summer 2026) in the HeyGen AI. This technology creates the most realistic human appearance possible on video. Its facial expressions, movements, lip-syncing during speech, and the near-total absence of a robotic effect are crucial when a motion designer is creating a deepfake. And it is Avatar IV that is available in the free version of HeyGen.

Synthesia clearly falls short when it comes to creating realistic avatars compared to HeyGen. But that’s not Synthesia’s main purpose. This AI tool is designed for more ambitious features:

• Over 660 avatars to choose from;

• The ability to add up to 20 avatars to video frames;

• Support for 32 languages for voiceovers;

• Over 2,100 voice tones and types.

Despite their different approaches and goals, the two AI tools are constantly being compared. Even on the official HeyGen and Synthesia websites, the homepages highlight the advantages of each.

But these AI platforms have one thing in common: their free plans aren’t sufficient for productive work.

HeyGen’s free plan allows you to create three videos per month, each no longer than one minute. You also get limited free access to Avatar IV, the video agent, and standard video processing.

Synthesia’s free plan is called Basic. You receive 1,200 credits per month—the platform’s currency used to pay for video generation. This is enough for 10 minutes of video. Users also get access to 25 AI-powered video resources.

The maximum video quality for HeyGen and Synthesia on the free plan is 720p. Additionally, all generated videos will feature the brand’s watermark.

AI aggregators are platforms that bring together several AI tools in one place. They are provided for free: users are allotted a certain number of generations per day, week, or month. However, in most cases, these resources primarily offer text models and models that generate images.

Why there are no aggregators featuring HeyGen and Synthesia:

1. Video generation is a labor-intensive and costly process, even for AI tools. Aggregators typically pay for a large batch of generations from an AI tool and then distribute them in portions to users for free or on a “free-with-conditions” basis. In other words, promoting video generation isn’t profitable.

2. HeyGen and Synthesia do not want their products distributed through third parties. AI video generators have imposed stricter restrictions on API usage.

3. Legal considerations. An aggregator that integrates a video generator could face legal action for deepfakes and copyright infringement.

There are also no free Telegram bots with access to HeyGen and Synthesia.

You can create an account on HeyGen or Synthesia using your Google or Apple account, or via email. However, both AI video generators prohibit having more than one account per user. This is how the platforms prevent users from circumventing generation limits.

If you simply create a new account with a different email address and start creating videos, HeyGen or Synthesia’s security system will quickly detect this. Both accounts will be blocked.

Smart algorithms track each user based on dozens of parameters:

• IP address and location;

• device OS type and version;

• browser type and version;

• online behavior, etc.

These platforms collect a digital fingerprint—data about the device and browser, behavioral patterns, and much more.

However, there is a solution to this problem.

Antidetect browsers allow you to log into HeyGen or Synthesia using multiple accounts completely safely. With these solutions, you can create and manage dozens of accounts without raising suspicion from the anti-fraud systems of these AI platforms.

Antidetect browsers help create isolated environments with a unique digital fingerprint on your device. The AI platforms won’t link accounts together, so you won’t get banned.

Vision is the ideal solution for using HeyGen or Synthesia for free. Most antidetect browsers generate artificial digital fingerprints, which may contain inconsistencies regarding the OS type and device. Vision, on the other hand, uses fingerprints collected from real devices. The profiles are realistic and resistant to detection.

Let’s use Vision as an example to see how to create a separate profile for a duplicate HeyGen or Synthesia account:

1. Sign up on the official Vision website;

2. Download and install the antidetect browser app. Vision is compatible with Windows, macOS, and Linux;

3. Log in to the app;

4. Select a pricing plan. You can use the four-day trial period to try it out;

5. Set up proxy solutions. Choose one proxy per profile;

6. Create a profile. Enter a name and set the necessary parameters;

7. Warm up the profile. Don’t visit AI video generator websites right away. First, browse the news, other pages, and search for information using a search engine.

Now you can create a second account on HeyGen or Synthesia. If you need a third or subsequent accounts, create a new profile in Vision.

Free access to HeyGen or Synthesia is severely limited. These AI video generators are among the best in the industry, but the limits make it impossible to work effectively. You won’t find any additional free requests on AI aggregators or Telegram bots either. The only solution is to use multi-accounting via antidetect browsers, such as Vision with its proxy solutions.
