# Synthesia is a polished enterprise avatar platform, but one-star reviewers cite price, credits, cancellation and support.

By Kevin · Every rating and review checked on 11 November 2026

We read Synthesia's public Trustpilot profile (3.8 out of 5 across 1,830 reviews), its pricing page and its homepage on 11 November 2026. 72% of reviewers give five stars, while 13% give one star, citing cost ("at least twice as expensive as other similar companies"), credits that run out on a monthly plan, a refused refund after cancelling, and a custom avatar that mispronounced industry terms. Synthesia is built for training and business video: 125+ stock avatars on Starter, 140+ translation languages and SOC 2 Type II. Zemith Plus ($15.99/month) is built for creators and marketers who want short presenter ads, talking photos, captions and dubbing plus video models and AI chat on 1.5M monthly credits.

## Zemith Plus gives creators presenter ads, talking photos, dubbing, captions and AI chat for $15.99/mo.

- Ad Maker turns a product photo into 9:16 presenter ads in three script angles (Hook, Problem to solution, Testimonial), with an AI-made presenter, your own photo or a saved AI Influencer character, and word-by-word captions.
- Talking photos and Lipsync make a photo or a clip speak your script or your own recording, and Language Swap dubs clips of up to 60 seconds into 21 languages with lip-sync (optional voice cloning in nine).
- Captions, Voice Change, Veo 3.1, Kling V3.0, Seedance 2.5 and Wan video, Director multi-shot films, Product Studio and GPT, Claude, Gemini and Grok chat all run on the same $15.99/mo Plus plan.
- Plainly: Zemith has no library of 125+ stock studio avatars reading a script for 30-minute training videos, and no SCORM export or enterprise compliance pack. It is built for creators and marketers who need short presenter ads, captions and dubbing plus the rest of the AI stack.

- **Synthesia Starter (monthly billing):** $19/mo (_1,250 credits, up to about 12 minutes of video; credits reset every month; no stock-avatar library or SCORM on Zemith_)
- **Zemith Plus:** $15.99/mo (_1.5M credits · Ad Maker + talking photos + Lipsync + Language Swap + Captions + Veo 3.1, Seedance 2.5 + GPT, Claude & Gemini_)

## How Synthesia is rated on Trustpilot.

### Trustpilot: 3.8/5 (1,830 reviews, read 11 Nov 2026)

Source: [Trustpilot](https://www.trustpilot.com/review/synthesia.io)

Most reviewers rate Synthesia highly, while the one-star reviews focus on price, credits, refunds and support:

- 5 stars: 72%
- 4 stars: 11%
- 3 stars: 2%
- 2 stars: 2%
- 1 star: 13%

Read on Synthesia's public Trustpilot page on 11 November 2026; 108 of the 1,830 reviews were posted in the past 12 months, and Trustpilot notes the company has not recently asked customers for reviews or replied to negative ones. We show Trustpilot only because we could not open a G2 star breakdown to verify it.

## The three complaints Synthesia users repeat most in 2026.

### Expensive, and credits run out fast on the monthly plan.

> “they are expensive,  at least twice as expensive as other similar companies” — [Trustpilot](https://www.trustpilot.com/review/synthesia.io), 1-star review, Oct 2026

> “I paid for the monthly plan and ran out of credits quickly when trying to generate videos.” — [Trustpilot](https://www.trustpilot.com/review/synthesia.io), 1-star review, Jun 2026

**On Zemith:** Zemith Plus is $15.99/month with 1.5M credits shared across every studio and chat, and every paid plan can add $10 top-ups (800,000 credits) that never expire. Each render shows its credit cost first.

### Cancelled but still charged, and a support loop that never fixes it.

> “at the end of the first year I cancelled but they still took my money and refused to refund it.” — [Trustpilot](https://www.trustpilot.com/review/synthesia.io), 1-star review, Feb 2026

> “What should have been a standard signup devolved into a chaotic, one-hour ordeal on live chat.” — [Trustpilot](https://www.trustpilot.com/review/synthesia.io), 1-star review, Sep 2026

**On Zemith:** Zemith's Free plan needs no card, paid prices are public, and you can cancel anytime from your profile.

### A custom avatar that mispronounced industry terms.

> “The avatar I generated of myself had mispronunciations of industry-specific terms that we were never able to fix” — [Trustpilot](https://www.trustpilot.com/review/synthesia.io), 1-star review, Jul 2026

**On Zemith:** Talking photos and Lipsync take your exact script or your own recorded audio (MP3, WAV or M4A), so a term you record yourself stays pronounced your way, and Lipsync keeps your real footage.

## What Synthesia genuinely gets right, and where Zemith is the better fit.

### Translation and dubbing across a very wide range of languages.

> “Automatically translate your videos into 140+ languages” — [Synthesia homepage](https://www.synthesia.io/), Official product claim, Checked 11 Nov 2026

**On Zemith:** Language Swap covers 21 languages for clips of 2 to 60 seconds, with lip-sync and optional voice cloning in nine. That fits ads, Reels and product demos, not long training libraries.

### Enterprise security and compliance for training teams.

> “SOC 2 Type II, ISO 27001, ISO 27701, and ISO 42001 certified, and GDPR compliant, with EU data residency” — [Synthesia homepage](https://www.synthesia.io/), Official product claim, Checked 11 Nov 2026

**Honest note:** Zemith makes no such compliance claims. If your legal team needs SOC 2 and SCORM for L&D video, Synthesia is built for that; if you make short ads and social video, you do not need to pay for it.

## Questions people ask about Synthesia.

### Is Synthesia worth it in 2026?

For teams that need 30-minute training videos with stock avatars, SOC 2 and SCORM, Synthesia is a mature choice, with a 3.8/5 Trustpilot score across 1,830 reviews. For short presenter ads and social video, $19 to $89 a month buys far fewer minutes than most creators need.

### What do people complain about on Synthesia?

Price, credits that run out on a monthly plan, a refused refund after cancelling, slow or scripted support, and custom avatars that did not pronounce industry terms correctly.

### Does Zemith have a library of stock avatars like Synthesia?

No. Zemith has no library of 125+ stock studio avatars reading a script. Ad Maker uses AI-made presenters, your own photo or a saved AI Influencer character for short 9:16 ads, and talking photos make a still speak your script.

### Can Zemith dub videos like Synthesia?

For short clips, yes. Language Swap translates clips of 2 to 60 seconds into 21 languages with lip-sync and can keep the speaker's own voice in nine. Synthesia covers 140+ languages and longer videos.
