How Much Does Synthesia Cost?
As of 2026, Synthesia costs $0 for the free Basic plan, about $18 to $29 per month for Starter, about $64 to $89 per month for Creator (the lower number on each is annual billing), and custom pricing for Enterprise. If you want animated explainers and avatars from a document, Knowlify is the document-to-video alternative, roughly 4x cheaper than a traditional studio.
Synthesia is the most widely used AI avatar video platform, with 50,000+ teams and a 4.7 rating from 2,000+ G2 reviews. Its pricing is subscription-based and tiered by video minutes, avatar access, and team features. The headline numbers are simple, but the real cost depends heavily on whether you bill monthly or annually, how many video minutes you actually need, and which add-ons your use case requires. Prices below are pulled from Synthesia's own pricing page; plans change, so treat these as a 2026 snapshot and confirm current numbers before you buy.
Synthesia Pricing at a Glance (2026)
| Plan | Price | Key limits | Best for |
|---|---|---|---|
| Free (Basic) | $0 | 1 editor, a limited monthly video allowance, 9 AI avatars, watermark, no MP4 download | Trying the platform before committing |
| Starter | ~$18/mo annual or $29/mo monthly | 10 min video/month (monthly), ~120 min/year (annual), 125+ avatars, 1 editor + 3 guests | Solo creators making AI avatar videos |
| Creator | ~$64/mo annual or $89/mo monthly | 30 min video/month (monthly), ~360 min/year (annual), 180+ avatars, API access, 1 editor + 5 guests | Small teams producing avatar video regularly |
| Enterprise | Custom (from "Let's talk") | Unlimited video minutes, 240+ avatars, SSO/SAML, SCORM export, dedicated CSM | Large orgs scaling on-brand video |
| Knowlify | From ~$0 to try; Studio from ~$1,000/project | Document-to-video animation + avatars, 72-hour Studio delivery | Animated explainers and avatars from existing docs |
Two things drive most of the price difference inside this table. First, billing cadence: Synthesia's advertised low prices (around $18 and $64) require annual prepayment; month-to-month is meaningfully higher at $29 and $89. Second, video minutes: every paid plan caps how many minutes of finished video you can generate, and unused minutes do not roll over.
Plan-by-Plan Breakdown
Free (Basic) plan
The free Basic plan lets you create AI avatar videos with no credit card, access a small set of stock avatars (around 9), and generate in 160+ languages. The catches are real: videos carry a Synthesia watermark, you cannot download the MP4, and the monthly video allowance is limited. It is a genuine "try before you buy" tier, not a plan you can ship client or customer-facing work from.
Starter plan
Starter runs about $18/month billed annually (roughly $264/year) or $29/month if you pay month to month. It unlocks MP4 downloads, removes the watermark, and adds the AI Video Assistant, AI Dubbing, and 125+ stock avatars. The annual plan includes one custom Personal Avatar. The headline constraint is 10 minutes of generated video per month (the annual plan is metered as roughly 120 minutes per year). For a solo creator making short, regular videos, that is workable; for anyone producing longer or higher-volume content, it runs out fast.
Creator plan
Creator is Synthesia's "most popular" tier at about $64/month billed annually (roughly $804/year) or $89/month monthly. It raises the allowance to 30 minutes of video per month, adds 180+ avatars, up to 5 Personal Avatars, API access, branded video pages, interactive videos, and multiple avatars per scene. This is the tier most small teams land on when avatar video becomes a recurring need rather than an experiment.
Enterprise plan
Enterprise is custom-priced ("Let's talk" / book a demo). It removes the minute cap (unlimited video), unlocks the full 240+ avatar library and unlimited Personal Avatars, and adds the features large organizations require: SAML/SSO, SCORM export for LMS delivery, Brand Kits, live team collaboration, a dedicated Customer Success Manager, and priority support. Public pricing is not listed, so budget for a negotiated annual contract rather than a fixed sticker price.
Hidden Costs to Watch
The plan price is rarely the all-in cost. The line items that most often surprise buyers:
- Monthly billing premium. The advertised low prices require annual prepayment. Choosing month-to-month flexibility costs roughly 35 to 60% more per month.
- Video minute caps and overages. Each plan caps generated minutes. If you exceed the limit, generation is paused until renewal and your only option is to upgrade. Unused minutes do not roll over.
- Studio avatar add-on. A studio-grade Personal Avatar is a paid add-on (listed around $1,000/year) and is available on annual plans, with multi-day processing.
- Generative clip and action credits. Newer features draw on a shared credit pool: Veo and Sora clip generation and avatar "action" b-roll consume credits per asset, which can eat into your effective allowance.
- API usage. API-generated video deducts from your plan's minute allowance, so automation at scale can quietly accelerate how fast you hit the cap.
- Per-seat scaling. Paid plans include a single editor (plus guests). Adding real editing collaborators generally means Enterprise.
None of these are unusual for a SaaS video tool, but they explain why teams that price Synthesia at "$29/month" often end up at a very different number once volume, seats, and add-ons are factored in.
Synthesia vs Knowlify: When Each Fits
Honest version: these tools are strongest at different jobs.
Synthesia is the leader for AI avatar video at scale. If your core need is a synthetic on-screen presenter delivering scripted content, in many languages, with enterprise governance (SSO, SCORM, brand controls), Synthesia is hard to beat. That is what it is built for, and the avatar quality and language coverage reflect it.
Knowlify is the fastest, roughly 4x cheaper document-to-video option, and it is strongest when you need animated explainers plus avatars generated from material you already have. Instead of writing a script into an avatar tool, you upload a PDF, slide deck, or knowledge-base article and Knowlify turns it into a narrated, animated video. For teams whose source content lives in documents, that removes the entire scripting-and-staging step that avatar-first tools assume you will do yourself.
Where Synthesia meters you by video minutes and avatar count, Knowlify is built around turning existing documents into finished video, with both a self-serve explainer video maker and a done-for-you Knowlify Studio track. If you specifically want a deeper feature comparison, see our Synthesia alternative breakdown. If avatar video is the only thing you need, Synthesia is the safer default; if you need animated explainers (with avatars available too) sourced from documents, on a tighter budget and timeline, Knowlify fits better.
How to Decide
Use these four steps to land on the right plan and platform without overbuying.
Step 1: Define your real video volume
Estimate finished minutes per month, not number of videos. Synthesia's plans live or die on the minute cap: 10 minutes (Starter), 30 minutes (Creator), or unlimited (Enterprise). If you cannot confidently stay under a cap, price the next tier up, because overage forces an upgrade anyway.
Step 2: Decide monthly vs annual
If you are certain you will use the tool for a year, annual billing is materially cheaper (roughly $18 vs $29 on Starter, $64 vs $89 on Creator). If you are still evaluating, pay monthly for a cycle or two first, then switch. Do not prepay annually to "save money" on a tool you have not validated.
Step 3: Map your must-have features
List the features you cannot ship without: watermark removal and MP4 download (Starter+), API access and interactive video (Creator+), or SSO, SCORM, and unlimited minutes (Enterprise). Buy the lowest tier that contains every must-have, and treat add-ons like studio avatars as separate budget lines.
Step 4: Pressure-test against your source content
If most of your content already exists as documents, decks, or articles, test a document-to-video workflow before committing to an avatar-first subscription. Run the same source material through Knowlify's explainer video maker and compare the finished animated output, the time spent, and the all-in cost against your Synthesia quote.
Across the 200,000+ videos produced on the platform, Knowlify Studio delivers finished video in as little as 72 hours, about 4x cheaper than a traditional production studio. That speed-and-cost profile is the practical reason teams pair or replace per-minute avatar subscriptions with a document-to-video workflow for explainer and training content.
FAQ
Is the Synthesia free plan worth using?
The free Basic plan is worth it for evaluation only. You can create AI avatar videos in 160+ languages with no credit card, but videos carry a watermark, cannot be downloaded as MP4, and the monthly allowance is limited. It is a genuine way to test avatar quality and the editor before paying, but not a tier you can publish customer-facing or commercial work from.
How much does Synthesia cost per month?
As of 2026, Synthesia's Starter plan is about $18/month billed annually or $29/month month-to-month, and Creator is about $64/month annually or $89/month monthly. Enterprise is custom-quoted. The lower price on each paid tier requires annual prepayment, so month-to-month flexibility costs noticeably more. Plans change, so confirm on Synthesia's pricing page.
Is Synthesia cheaper than HeyGen?
It depends on plan and usage, since both meter by video minutes and seats and run frequent promotions. Rather than rely on a single snapshot, compare current numbers side by side: see our HeyGen pricing breakdown and the head-to-head Synthesia vs HeyGen comparison before deciding which is cheaper for your specific volume.
What is a cheaper alternative to Synthesia?
If you mainly need avatars, compare avatar tools in our best AI avatar generators roundup. If you need animated explainers built from existing documents (with avatars available too), Knowlify is the document-to-video alternative, roughly 4x cheaper than a traditional studio, with Studio delivery in as little as 72 hours. You can start free and compare the output against a Synthesia quote.
Can I cancel or switch Synthesia plans anytime?
Yes. Per Synthesia, you can cancel anytime from your account settings, and you can upgrade at any time. Upgrading a Starter or Creator plan to annual billing, or moving to Enterprise, may require contacting support or sales. Note that unused video minutes do not roll over when you cancel or renew, so plan timing around your billing cycle.
