Polished, studio-clean avatars with the cheaper safe entry of the two big avatar tools, but the free plan's watermark and 10-minute cap rule it out for anything monetized.

Based on current public terms this appears high-risk to monetize as-is; there's usually a defined safe fix (a paid tier).
Every factor is backed by the tool's own primary source.
The safe fix→ 25/100 · Mostly safe
Upgrade off the free 'Basic' tier to Starter (advertised "$ 29 /mo" billed monthly, and a "$ 18 /month" headline when billed yearly as of 2026-06-16, confirm the exact price at checkout, since Synthesia is mid-promotion "NEW LOWER PRICES"). Starter is the cheapest tier that removes BOTH free-tier blockers: the pricing page lists Starter as "What you get in Basic + Download your videos ... Remove Synthesia logo", meaning Basic has NO MP4 export and a forced, non-removable watermark, while Starter unlocks clean download and logo removal. Ownership is unchanged by tier ("Customer will own all Customer Data"), so once the watermark and download gate are gone the output is a publishable, monetizable asset. Two residual conditions a creator must respect even on paid: (1) the AUP requires use "for your organization's or company's business needs, rather than for consumer, personal or household purposes", monetized faceless-creator/business content qualifies, purely personal/household videos do not; and (2) the AUP prohibits "Incorporating a Stock Avatar in content for promoted, boosted, or paid advertising on any social media platform or similar media, absent written express consent from Synthesia", so a Stock Avatar in paid social ads still needs Synthesia's written consent; use a Personal/Custom Avatar (Starter and up) to sidestep this. Estimated paid lens: scorePaid 25, bandPaid "Mostly safe".

Reproduce it yourself: each factor's risk points = weight × level ÷ 4 (an unclear factor counts as half its weight). The seven add up to 60. Every scored factor quotes Synthesia’s own current terms, pricing or help page.
Commercial-use rights
Level 2/414 / 28 pts
Does the license actually permit monetizing the free-tier output (monetized video / paid client deliverable)? The single most decisive factor.
“Use the Services for your organization’s or company’s business needs, rather than for consumer, personal or household purposes.”
The Acceptable Use Policy governs ALL use of the Services (free 'Basic' users are 'Customer' under the Customer Terms: 'If the Services are being set up by someone who is not formally affiliated with an organization, Customer is the individual setting them up'). It does not deny commercial use, it REQUIRES use to be for 'business needs, rather than for consumer, personal or household purposes,' i.e. commercial/business use is the contemplated, permitted use. Combined with the Customer Terms granting video ownership ('Customer will own all Customer Data'), commercial use is granted but CONDITIONAL: it must be a genuine business use, and the Stock-Avatar paid-advertising restriction (see attribution/AUP) can trip a creator. Conditional commercial grant a creator can trip => L2. No free-specific monetization carve-out exists either way, so this rests on the generally-applicable business-use clause (reflected in Medium confidence).
Free-plan monetization gate
Level 4/418 / 18 pts
Free-tier blockers that make output unusable even when commercial use is allowed: watermark, 'personal-only' wording, publish-barring caps.
“What you get in Basic + Download your videos AI Video Assistant AI Dubbing Remove Synthesia logo”
On the pricing page, BOTH 'Download your videos' AND 'Remove Synthesia logo' are listed under what the paid Starter tier ADDS on top of Basic. That means the free 'Basic' plan has NO MP4 download and a forced Synthesia watermark on every render. With no export and a non-removable watermark, the free tier cannot produce a clean, publishable, monetizable asset at all => L4.
Output ownership & sublicensing
Level 2/48 / 16 pts
Do you own (or get a clean, transferable, sublicensable license to) the output? Decisive for agency/client work where rights must be handed over.
“We grant to Customer a non-sublicensable, non-transferable, non-exclusive, limited license for Customer and its Authorized Users to access and use the Synthesia Content made available through the Services during the term of an applicable subscription, and after the term to the extent it has been incorporated in videos generated using the Services”
You own the video itself ('Customer will own all Customer Data'), but the embedded Synthesia Content (stock avatars, templates, library media) is licensed under a 'non-sublicensable, non-transferable' license. The license is tied to the subscription term BUT survives post-term for Synthesia Content already incorporated into videos you generated ('and after the term to the extent it has been incorporated in videos generated using the Services'), so finished videos remain usable after you stop paying. Because the underlying assets are non-transferable/non-sublicensable, the composite output's rights are non-transferable => L2.
Attribution / branding obligation
Level 3/49 / 12 pts
Must you credit the tool, keep a logo, or disclose it by name? An enforceable monetization burden even when commercial use is allowed.
“Removing, deactivating or disabling any ‘watermarks’ or other mechanisms of the Services that are designed to help validate provenance or differentiate between human-generated and AI-generated content.”
Every free 'Basic' render carries the Synthesia logo/watermark ('Remove Synthesia logo' is a paid-only Starter feature per the pricing page), and the AUP expressly prohibits removing or disabling that watermark. A forced, non-removable on-screen provenance/brand mark on free output = mandatory on-screen credit/forced watermark-credit => L3. (Borderline: the Synthesia logo is arguably an L4 persistent brand watermark; scored L3 as the lenient read, either way the band stays Risky.)
Copyright & training-data exposure
Level 2/46 / 12 pts
Risk the output infringes third-party rights or triggers a platform claim: training-data provenance, indemnity, likeness/voice-clone consent, YouTube synthetic-content exposure.
“we will defend and indemnify Customer for any Claims Against Customer that constitute third party copyright infringement claims arising from our creation or development of any artificial intelligence components of the Services. This indemnification obligation is referred to herein as our “AI Copyright Pledge”.”
Synthesia gives an explicit 'AI Copyright Pledge' (indemnity for third-party copyright claims arising from its AI components), which lowers training-data exposure. However, the output is a realistic AI human presenter, which triggers YouTube's altered/synthetic-content disclosure requirement (the disclosure itself does not cut monetization). Net exposure sits at L2. (Quote normalized to the source's double-quote rendering of “AI Copyright Pledge”.)
Terms stability
Level 1/42 / 8 pts
How likely are today's rights to be quietly changed or revoked tomorrow? Modification clause, retroactivity, notice, and observed change history. The factor the ToS-monitor sells against.
“This policy may change as the Services and industry evolve, so please check back regularly for updates and changes.”
Standard 'we may update; check back' modification language. The AUP is 'Last Updated: February 23, 2024' and the Customer Terms are 'Effective: February 23, 2024', stable, with no documented retroactive or adverse change in the past 12 months => L1.
Creator practicality
Level 2/43 / 6 pts
The gap between 'technically licensed' and 'actually usable safely': terms clarity/findability, login-gated pricing, credit-model traps. Modulates, never decides.
“Includes 1,200 credits /mo What are Credits? Credits are now the shared currency across all AI usage-based features - one common pool for everything you create. Usable for up to 10 minutes of video/month”
Pricing is public, but the rights picture is split across three legal documents (Customer Terms, User Terms, Acceptable Use Policy) plus a credit-based usage model ('1,200 credits /mo' mapped to '10 minutes of video/month') that obscures exactly what a free user can actually produce and publish. Reaching a clean answer on free-tier commercial rights requires cross-reading multiple pages => L2.
What we couldn’t confirm from a primary source
▸ No Synthesia primary page (terms/pricing/EULA/official statement) grants commercial or monetization rights SPECIFICALLY to the free 'Basic' tier. commercialUse is scored L2 from the Acceptable Use Policy's general 'business needs, rather than for consumer, personal or household purposes' requirement, which governs ALL tiers (free users are 'Customer' under the Customer Terms) and permits conditional business/commercial use, but it is a generally-applicable clause, not a free-specific monetization grant. Hence confidence Medium, not High.
▸ The prior review's licenseQuote 'Free workspace videos include a watermark and may not be used for commercial purposes' could NOT be located on any current live Synthesia page (terms, AUP, or pricing) and appears outdated/fabricated; it was removed.
▸ Whether the forced Synthesia logo on free renders is a co-brand 'credit' (L3) vs a persistent brand watermark that brands content as theirs (L4) is a borderline call; scored L3 (the more lenient read). Does not change the Risky band.

We paid for the plan ourselves and re-read the terms on June 22, 2026, so the watermark, license, and attribution calls above are first-hand, not guessed.
How we verified this
We don’t run generation tests, we read the fine print. For Synthesia we read the free tier’s own terms, its commercial-use, watermark and attribution rules, then confirmed the cheapest plan that lifts them against the official pricing page, cross-checked across multiple current sources. The watermark and license clauses below are paraphrased from those terms, and the quality score is our editorial read of the tool, not a lab benchmark. Everything here was last verified June 22, 2026.
Watermark & licensing, the part that decides monetization
✕Why the free plan fails: Watermark on free + 10 min/month cap
Watermark
Free renders are watermarked, and the 10-minute monthly cap means you can't even stockpile drafts. Treat the free tier as a way to evaluate avatars and templates, not as a production lane.
License
Commercial use requires a paid plan. Starter (~$18/mo) removes the watermark and grants commercial rights with a monthly minute allowance, enough for a Shorts-first channel, tight for long-form.

Is 10 free minutes a month enough to run a channel?+−
Not a monetized one, every free render is watermarked regardless of length. The cap exists so you can evaluate the product, and for that it's fine.
Is Synthesia Starter enough for Shorts?+−
Usually yes. A 30–45 second Short burns under a minute per video, so the monthly allowance covers a steady Shorts schedule. Long-form daily uploads will outgrow it.
Synthesia or HeyGen?+−
Synthesia wins on price and languages; HeyGen wins on lip-sync and natural delivery. Our comparison page puts the two free plans and safe plans side by side.
