The best Synthesia alternative depends on what you need to film. For short vertical product videos in a UGC (user-generated content) style for TikTok Shop, look at UGC tools like Creatify, Arcads or ours. For an all-purpose avatar, HeyGen. For corporate training, Colossyan is the closest match. Synthesia itself is built for large companies.

Quick note: we mean Synthesia the AI avatar video generator, not the piano learning app with the same name. Full disclosure: the #1 tool on this list is ours. That's why we also tell you, further down, when Synthesia is still the better pick.

New to this category? Start with our comparison of the best AI UGC video generators. This page answers one question: what to use instead of Synthesia when your goal is selling products on TikTok.

The table below sums up the five options, with Synthesia as the reference point. Entry prices were checked on October 23, 2026, where they could be confirmed. The #1 tool's price comes from its own rate card dated September 29, 2026. Where a price couldn't be confirmed, the cell sends you to the official site.

Why look for a Synthesia alternative in 2026?

Synthesia is a strong tool, but it is built for corporate training and internal communication. Its plans are priced in dollars with video counted in minutes. If you want 15-second vertical product videos that sell on TikTok Shop, a tool designed for UGC-style content fits that job better.

The numbers show where Synthesia is headed. On January 26, 2026, the company announced Synthesia's $200M Series E at a $4B valuation, led by GV (Google Ventures). Its previous round valued it at $2.1 billion.

Users like it too. On G2, Synthesia holds 4.6/5 from 2,755 reviews (accessed October 23, 2026). Nothing wrong with any of that. But a tool funded to win big enterprise accounts doesn't solve your evening problem: getting three product videos posted before bed.

And the field keeps growing. The AI avatar market forecast from Grand View Research (2026 report) values the global AI avatar market at $808.4 million in 2025. It projects $7.9 billion by 2033, a 32.9% annual growth rate. More tools means more choice, and more noise to sort through.

4 criteria for picking a TikTok Shop video tool

To replace Synthesia for videos that sell, judge each tool on four points: vertical 9:16 output, a natural American English voice, face-to-camera UGC-style delivery, and cost per short video. Cost per minute, useful for a training module, tells you almost nothing about a 15-second clip for your TikTok Shop products.

• Vertical 9:16 output: it's the format of TikTok, Reels and Shorts. A horizontal video cropped to vertical loses half the frame.

• A natural American English voice: test it with your own script, product names and prices included. That's where robotic voices give themselves away.

• Face-to-camera delivery: on TikTok, a video that looks like a corporate course gets swiped in a second. People stop for someone who talks to them like a friend.

• Cost per short video: divide the monthly price by the number of 10 to 20-second videos you can actually produce.

One last thing. Most of the comparisons ranking on Google are written by competitors. HeyGen's own Synthesia alternatives roundup ranks HeyGen first. Colossyan publishes two pages that put Colossyan first. Fair game. Keep it in mind, including while reading this one.

1. Klonify: TikTok Shop product videos from a product link

Klonify is a French tool that generates sales videos for TikTok Shop: from a product link, it writes the script, produces the voiceover and creates the AI influencer who presents the product face to camera, from €19/month. Dialogue can be generated in English, and every plan is month-to-month.

Why #1? Because it's built for the case every other comparison skips: the TikTok Shop affiliate or seller who needs a steady flow of short product videos. You paste a product link, and the AI writes a sales script. The built-in video editor comes free with every plan.

On cost, a 10-second video uses 100 credits. The Standard plan gives you 750 credits a month, enough for about seven and a half 10-second videos, or roughly €2.53 per video. The Pro plan (€39/month, or €29/month billed annually) raises that to 1,800 credits and 1080p export.

Let's be straight: per second of video, Synthesia is cheaper, with about 10 minutes for $29 on its Starter plan. But you're not buying the same result. One gives you an avatar presenting a module. The other gives you a sales video with a script, voice and influencer designed for TikTok.

Here's what the tool does, and what it will never do for you (rate card dated September 29, 2026):

Paste the link of a product you already promote and see what comes out: create your first product video.

2. HeyGen: the best-rated all-purpose avatar tool

HeyGen is the top Synthesia alternative listed on G2, with a 4.8/5 rating from 1,841 reviews (accessed October 23, 2026). It's an all-purpose avatar generator for presentations and social media alike. It fits if you make a bit of everything and product videos are only one use among many.

Strength: the highest user rating in this group on G2's list of Synthesia alternatives, ahead of Descript, VEED and Colossyan Creator (each at 4.6/5). It also has a free plan capped at 3 videos a month, with paid plans from $24/month billed annually, according to HeyGen's blog (October 23, 2026).

Limit: HeyGen ranks itself first in its own roundup, and the tool isn't built around TikTok Shop. Confirm current prices on its pricing page before you subscribe. For a deeper look, read our HeyGen alternatives for TikTok Shop.

3. Creatify: video ads for ecommerce brands

Creatify is an avatar video ad generator built for online stores that want to test several UGC-style ads. It belongs to the same family as the #1 tool on this list: videos that sell rather than videos that train. Test the voice on your own script before you pay for a plan.

Strength: a clear focus on ecommerce advertising. Limit: prices weren't checked for this article, and the sources we reviewed show no specific TikTok Shop workflow. Check its pricing page first.

4. Arcads: avatars for paid social ads

Arcads produces UGC-style videos with avatars, mostly for advertisers who buy ads on social platforms. If you already run paid ads on Meta or TikTok and want many versions of the same ad, it's worth a trial. For an affiliate just starting out, it's often more tool than you need.

Strength: built to spin one ad into a series. Limit: prices weren't checked for this article, so work out the cost per 15-second video before you compare. Our Arcads alternatives roundup goes further.

5. Colossyan: the closest match for training

Colossyan is the closest Synthesia alternative on Synthesia's home turf: internal training. Its comparison page highlights course authoring, quizzes, auto-translation and per-seat pricing. If you're replacing Synthesia to train teams, it's the logical next step. To sell a product on TikTok, it's the wrong fit.

Strength: features designed for training modules. Limit: per-seat pricing assumes a team, and product videos aren't part of its pitch. On G2, Colossyan Creator holds 4.6/5 from 492 reviews (accessed October 23, 2026).

How many sales cover your subscription?

Divide the monthly plan price by what one sale earns you. On TikTok Shop, each seller sets the affiliate commission rate, and there's no official average. With a $25 product at a 15% commission (a hypothetical example), TikTok Shop pays you $3.75 per sale, so 6 sales cover a €19 plan (about $21).

The table applies the same hypothetical example to several plans. Prices were checked on October 23, 2026 (Synthesia, HeyGen) or come from the rate card dated September 29, 2026 (the #1 pick). Dollar figures for euro plans are rough conversions, so check today's rate. This is a break-even calculation, not a sales forecast.

Before you count sales, you need affiliate access. According to TikTok Shop's US Creator Eligibility Policy, dated September 25, 2026, you need at least 1,000 followers, must be 18 or older, based in the US, and pass identity verification. The threshold shown in your Creator Center is what counts.

Under 5,000 followers, you're automatically enrolled in a pilot program. Per TikTok Shop's Affiliate Creator Pilot Program page, dated May 13, 2026, that means up to 3 shoppable videos a day and 3 shoppable LIVEs a week. So three strong videos a day is the volume to plan for.

Selling your own products instead? Your math changes. According to TikTok Shop's Referral Fees by Category page, dated October 8, 2026, the US referral fee is 6% for most categories, and 5% for some jewelry subcategories and refurbished or pre-owned items. Your videos have to cover that fee on top of any tool subscription. TikTok Shop has been live in the US since September 12, 2023, according to TikTok Newsroom.

When Synthesia is still the better pick

Keep Synthesia if you produce training or internal communication videos, in several languages, for a large organization. That's its home ground, and its funding and user base back it up. The UGC tools on this list don't try to beat it there, and you shouldn't force them to.

• You train teams with modules that run several minutes.

• You need the same video in many languages.

• Your company wants a custom-quoted Enterprise plan with a dedicated contact.

A concrete example: the #1 tool on this list generates dialogue in English or French only. If you need the same video in Spanish, German and Italian, it won't help you with that part.

Your own AI avatar: what to check first

Some tools let you build an AI avatar with your own face and voice, including the #1 pick on its Pro and Ultra plans. Before you do, check who owns the rights to the avatar and what the tool can do with it. For someone else's likeness, get their written consent.

• Read the terms: who owns the avatar, and can the tool reuse your face or voice?

• Get written consent from anyone whose face or voice you clone.

• Never clone a celebrity or a creator you saw on TikTok.

• Save a copy of the consent and of the terms on the day you sign up.

Synthesia's own CEO makes the same point. “Every actor or celebrity licenses their likeness,” Victor Riparbelli, Synthesia's co-founder and CEO, said on the Ground Level AI podcast.

Same logic for you: your face has value. Only hand it to a tool whose terms you've read.

Verdict: which Synthesia alternative should you choose?

Choose based on what you publish. To sell products on TikTok Shop, pick a UGC tool and start with the #1 option on this list. For all-purpose avatars, go with HeyGen. For paid ads at volume, Arcads or Creatify. For training, keep Synthesia or move to Colossyan.

• TikTok Shop affiliate or seller: a UGC tool priced per short video, with a natural English voice.

• All-round creator: HeyGen.

• Paid social advertiser: Arcads or Creatify.

• Multilingual training team: Synthesia or Colossyan.
