## What it is

Synthesia is an AI video generation platform that creates professional videos using AI avatars and text-to-speech. Users type scripts and select from 125+ stock avatars to generate videos without cameras, actors, or studios. Used primarily for corporate training, marketing, and internal communications.

## Common problems

- **Inconsistent and unpredictable content moderation** (support): Content moderation is arbitrary and lacks transparency. Videos approved one day get flagged the next with nearly identical edits - changing an image or fixing pronunciation triggers rejection. Users left guessing what triggers moderation, creating frustration and wasted time. Healthcare, biotech, and medical users report being blocked entirely without explanation.
- **Strict no-refund policy even for immediate issues** (pricing): Despite using the platform for only two days, Synthesia refuses refunds citing their strict no-refund policy. Users requesting refunds within the stated 15-day consumer refund period report being refused. Support agents refuse to transfer to supervisors. Customers lose money without receiving working service.
- **Accounts banned within minutes of subscribing** (support): Some users report having their accounts banned within 30 minutes of subscribing while creating legitimate promotional videos. This occurs without warning or clear explanation. Combined with the no-refund policy, users lose both access and money immediately.
- **Every video requires human review - adds days** (usability): Every video generated on Synthesia requires human review before download, adding 1-2+ days to the process. This defeats the purpose of using AI for quick and efficient video production. Users expecting instant turnaround are frustrated by mandatory waiting periods.
- **Avatar quality and lip-sync issues** (usability): Avatar quality varies significantly, with facial features often not matching spoken words. Lip-sync accuracy is criticized across multiple platforms. Some avatars fall into the 'uncanny valley' - realistic enough to be unsettling but not enough to be natural. Expressions and gestures feel stiff.
- **Customer support hides behind policy links** (support): Customer support has been criticized for hiding behind policy links and warnings rather than offering real solutions. Users describe it as dealing with an automated system rather than a team that values paying customers. Technical issues and upgrade inquiries get slow responses.
- **Videos stuck at 99% or fail to render** (reliability): Common technical issues include videos getting stuck during processing (especially at 99% completion) and failing to render entirely. Some users report 80% of videos getting stuck. Resolution issues cause videos to become blurry, requiring redo.
- **Credits don't roll over month to month** (pricing): Video credits expire monthly with no carryover. For consultants and teams with variable workloads, this creates waste during slow months. If credits could bank even for two months, it would fit better with how consultants actually work. The system isn't designed for fluctuating production schedules.
- **Enterprise pricing escalates with seats and workspaces** (pricing): The platform is expensive for big teams, with costs escalating significantly when adding seats and workspaces. API access requires higher-cost plans. Enterprise contracts involve custom pricing that often surprises organizations after initial quotes.
- **Custom avatar creation rejected for minor issues** (usability): Users developing their own custom avatars face stringent rules that reject images for simple issues like brightness problems. The process is frustrating when legitimate business use cases are blocked by overly strict automated filters.
- **Robotic voices on longer narrations** (usability): Voices can still sound robotic on longer narrations or when nuanced emotion is needed. The text-to-speech quality struggles with complex emotional delivery. Shorter clips sound better than extended scripts.
- **Limited editor requires external tools** (usability): The built-in editor is intentionally simple, meaning limited timeline control, transitions, and audio mixing. Advanced edits require exporting and using external tools, fragmenting the workflow that was supposed to be all-in-one.
- **No control over avatar gestures and expressions** (usability): Users lack complete control over the gestures, expressions, and movements of virtual presenters. Avatars sometimes feel stiff, especially when expressive delivery is needed. The preset animations limit creative control.
- **No self-service account deletion** (support): There is no self-service way to close or delete your account. Users must contact support and wait for them to process it. This creates unnecessary friction for users wanting to leave the platform.
- **Render queues at peak times** (reliability): Users experience occasional render queues during peak times, adding unexpected delays to video production. Cloud-based rendering means you're dependent on server availability, which can vary.

## What users like

## Pricing

- **Basic (Free)**: $0 (free) — hidden costs: Very limited - essentially a trial. No commercial use rights.
- **Starter**: $18 (monthly) — hidden costs: Credits don't roll over. $29/month if paid monthly (38% markup).
- **Creator**: $64 (monthly) — hidden costs: $89/month if paid monthly. Still no API access or custom avatars.
- **Enterprise**: $0 (usage_based) — hidden costs: Custom pricing - typically very expensive. Per-seat costs escalate quickly.
- **Pay-as-you-go Credits**: $0 (usage_based) — hidden costs: Credit pricing not transparent - must contact sales for bulk rates

## Who should and shouldn't use it

- **Corporate training and L&D teams** — Good fit: Primary use case - reduces training video production time by 50%. Easy localization for global workforces. LMS integration available. Templates standardize output. Strong ROI for organizations producing many short training videos.
- **Healthcare and biotech companies** — Avoid: Content moderation rules explicitly block healthcare, biotech, and medical diagnostics companies from using stock avatars. Many users in these fields report videos being denied without explanation. Consider HeyGen or custom solutions instead.
- **Marketing teams needing quick promo videos** — Depends: Fast turnaround is helpful for marketing, but mandatory human review adds 1-2 days. Content moderation unpredictability creates risk for campaign deadlines. Better for internal comms than time-sensitive external marketing.
- **Small businesses and solopreneurs** — Depends: Starter plan at $18/month is affordable, but credits don't roll over - waste during slow months. Content moderation can block legitimate business videos. Consider HeyGen's more flexible free tier for testing first.
- **Consultants with variable workloads** — Avoid: Credits expire monthly with no carryover. The system isn't designed for fluctuating production schedules. Heavy months drain credits; light months waste them. Poor value for project-based work.
- **Enterprise with compliance needs** — Good fit: $4B valuation and $535M+ funding indicate stability. SOC 2 compliance, SSO, dedicated CSM, custom contracts. However, prepare for lengthy sales cycles and escalating per-seat costs.
- **Users needing expressive avatar performances** — Avoid: Limited control over gestures and expressions. Avatars feel stiff compared to HeyGen's more expressive delivery. Lip-sync issues and uncanny valley effects persist. Better options exist for emotionally nuanced content.
- **Teams needing quick iterations** — Avoid: Every video requires human review adding 1-2+ days. Content moderation may reject videos unpredictably, requiring re-submission. Not suitable for rapid iteration or last-minute changes to production schedules.

## Alternatives

- **Colossyan**: L&D teams switch for interactive features like branching quizzes and multiple-choice scenarios. Gain: Built-in interactivity for training, LMS-ready output, structured slide-based approach. Trade-off: More rigid avatar delivery, less expressive for marketing content.
- **Elai.io**: Budget-conscious teams switch for competitive pricing with similar features. Gain: Lower cost per video minute, simpler pricing structure, good avatar quality. Trade-off: Smaller company, less enterprise support.

- **Loom** (https://www.tryorbye.com/products/loom): Teams wanting authenticity switch to real presenter recordings. Gain: Authentic human connection, no avatar uncanny valley, simpler workflow. Trade-off: Requires actual recording, no AI avatar features, less scalable for localization.

## FAQ

### Is Synthesia worth it in 2026?

Synthesia provides strong value for corporate training teams creating many short videos with localization needs. However, the mandatory human review (1-2 days), expiring credits, and unpredictable content moderation frustrate users needing fast turnaround. Healthcare, biotech, and medical companies cannot use stock avatars at all. At $4B valuation with $535M+ funding, the platform is stable but alternatives like HeyGen offer more flexibility.

### Why was my Synthesia account banned?

Users report accounts being banned within 30 minutes of subscribing while creating legitimate content. Synthesia's content moderation is described as 'inconsistent, subjective, and lacking transparency.' Videos approved one day may be flagged after minor edits. Healthcare and medical content is often rejected without explanation. Combined with the no-refund policy, this creates significant financial risk.

### Does Synthesia have a refund policy?

Synthesia enforces a strict no-refund policy. Users report being refused refunds even after requesting within the 15-day consumer period or after only 2 days of use. Support agents reportedly refuse to transfer to supervisors. This policy combined with content moderation bans means users can lose money without receiving working service.

### How long does Synthesia video generation take?

While AI generation is fast, every Synthesia video requires mandatory human review before download. This adds 1-2+ days to the process, defeating the purpose of AI speed. Users expecting instant turnaround are frustrated. Render queues during peak times add additional delays. Plan for 2-3 day total turnaround, not minutes.

### What is the best Synthesia alternative?

HeyGen is the top alternative for more expressive avatars with instant generation (no human review delay). Colossyan is best for L&D teams needing interactive quizzes and branching scenarios. D-ID offers developer-friendly API access. Loom is the alternative when you want authentic human presenters instead of AI avatars.

### Can I use Synthesia for medical or healthcare content?

No - Synthesia's content moderation rules block healthcare, biotech, medical diagnostics, and related scientific fields from using stock avatars. Many users in these industries report videos being denied without explanation. This is a platform-wide policy, not a bug. Consider HeyGen or custom avatar solutions for medical content.

### Do Synthesia credits roll over?

No - Synthesia credits expire monthly with no carryover to the next period. If credits could roll over even for two months, it would help users with variable workloads. The current system wastes credits during slow months and creates artificial pressure to produce. This is a common complaint from consultants and project-based users.

### Is Synthesia avatar lip-sync accurate?

Lip-sync accuracy is criticized across review platforms. Users report facial features often not matching spoken words, creating an 'uncanny valley' effect. Some avatars look realistic enough to be unsettling but not enough to be natural. Quality varies between avatars. HeyGen is often cited as having more natural lip-sync.

### Why are my Synthesia videos being rejected?

Content moderation is described as 'inconsistent and entirely subjective.' Videos approved with one version may be flagged after minor edits like changing an image or fixing pronunciation. There's no clear list of prohibited content. Healthcare/medical content is systematically rejected. Users are left guessing what triggers moderation.

### How much does Synthesia cost per video?

Starter plan ($18/month annual, $29/month monthly) includes 10 minutes of video. Creator ($64/month annual, $89/month monthly) includes 30 minutes. At Starter rates, that's roughly $1.80-2.90 per minute. Enterprise pricing is custom and typically more expensive. Credits expire monthly - unused minutes are lost.

### Is Synthesia or HeyGen better?

HeyGen's avatars are more expressive and natural, with instant generation (no human review). Synthesia has stronger enterprise features (SSO, LMS integration, $4B backing). HeyGen supports 175 dialects vs Synthesia's broader avatar library. Choose HeyGen for marketing/expressive content; Synthesia for structured corporate training with compliance needs.

### Can I delete my Synthesia account?

No self-service account deletion is available. You must contact support and wait for them to process it. This creates unnecessary friction for users wanting to leave the platform, especially those frustrated by content moderation or billing issues.
