Synthesia alternatives

Why ad buyers switch from Synthesia

Synthesia’s Acceptable Use Policy (23 February 2024) bars “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”. A boosted organic post is caught too.

Its help centre (22 July 2026) adds that stock avatars can’t “Endorse products or services”, with no plan exception. A testimonial-style ad needs a personal avatar of someone who consented.

The plan details push the same way. Basic cannot download, so a free video never leaves Synthesia as a file. Unused minutes “do not roll over to the next billing period” (pricing FAQ). The Customer Terms ask for notice “at least thirty (30) days before the end of a subscription term” to stop a renewal.

What users report points the same way for ads. Reviewers call it overkill for short social clips (3 of 69 sources: Trustpilot, YouTube). Credits run out quickly and expire each month (11 of 69 sources: Trustpilot, Trustpilot).

Synthesia stays a fit for training, explainers and personal-avatar ads with consent. The Synthesia profile and Synthesia pricing cover that side.

Which free plans allow Synthesia-style avatar ads?

No free plan here gives a plain yes for a stock-avatar ad. One reads “Allowed with conditions” in the AI commercial use matrix (JoggAI), and the rest bar ads or leave them unclear.

• HeyGen Free bars ads. Free output may not be “used in connection with commercial activities, advertising” (terms s.4).
• JoggAI Free allows them with conditions. The terms do “not restrict your ability to use User Output for your own purposes (including for commercial purposes)”, but say nothing on stock avatars in ads (terms).
• Captions Free is unclear. The app terms grant no advertising licence in words, and 3.1(xiv) bars commercial use of Mirage content without its written consent.
• Creatify Free is unclear. “Users of the Free Tier have limited rights” (terms section 1), with no list.
• The D-ID trial bars ads, as “for non-commercial use only” (EULA 3.1).

What a 30-second ad costs on each

Every charted alternative costs more per 30-second ad than Synthesia Starter, and Argil costs least of the three.

HeyGen and JoggAI bill without a published rounding rule, so their figures are pro rata and sit outside the chart. HeyGen Creator costs $0.10 to $1.16 and JoggAI Starter $0.12 to $0.24 (HeyGen credits article, JoggAI pricing, checked 2 October 2026). Arcads publishes no price.

HeyGen: stock avatars in ads on paid plans, in 175+ languages

HeyGen makes talking-avatar videos from text, photos or your own digital twin. Its paid plans open commercial use (terms s.3, 23 July 2026), and its stock avatars page answers the ad question: “Yes, on eligible paid plans. You can use HeyGen videos for ads”.

That is the clause Synthesia’s AUP withholds. The matrix reads it as allowed with conditions. You may not present output as entirely human-made, and the moderation policy bans ads for alcohol, weapons or online gambling.

Creator lists $29 a month for 600 credits (pricing page). Avatar III with a Video Look bills 4 credits a minute and Avatar V 48. So a 30-second ad costs $0.10 to $1.16 pro rata, or $0.19 on Avatar III billed by the whole minute.

Paid plans list 175+ languages against Synthesia’s 160+, and Creator includes one custom digital twin. Monthly credits roll over for one more month. HeyGen vs Synthesia sets the two side by side.

Best for

Localising one ad script into many languages, cheap avatar minutes for talking-head ads, and founder or spokesperson clones on a paid plan.

Not for

Anyone planning to run ads made on the free plan, which the terms forbid, and advertisers of alcohol, online gambling or weapons, which the moderation policy bans.

Arcads: an actor library licensed for ads, at a price it does not publish

Arcads sells script-to-video ads read by 1,000+ AI actors. Its terms (22 September 2026) grant “the right to distribute, broadcast and market the Video” (13.3.1), and actor videos carry their own conditions (13.3.2).

Those conditions bite. An actor’s creator can limit fields of activity or withdraw, and you must then delete the videos everywhere or owe 100 euros a day. Breaching an actor video’s conditions costs 500,000 euros per unauthorised use if not remedied within 30 days.

Prices are not published: the pricing URL returns a 404 page, and the help centre gives credits only (8,000 a month on Starter). Talking actors cost 800 credits a minute, and “Length is always rounded up”. The Arcads profile works through the credit rules.

Best for

Talking-actor ads close to a whole minute long, if billing rounds up to the minute as the help centre’s one example suggests.

Not for

Buyers who need a public price, or cheap 15 to 30-second hooks: length is rounded up, and the one example rounds to the minute. Actor-as-customer scripts risk the deceptive advertising ban (terms 13.3.1).

JoggAI: avatar credits that roll over for up to three months

JoggAI makes avatar, product-avatar and URL-to-video ads on one credit balance across its app, API and MCP. Starter lists $29 a month for 12,000 credits a month, and unused monthly credits “can roll over for up to three months” (pricing page). Synthesia’s do not roll over at all.

A 30-second ad costs $0.12 to $0.24 on JoggAI’s own approximations for standard avatars. HeyGen Creator’s Avatar III floor sits lower, so JoggAI is no saving against HeyGen.

On ads, the terms allow commercial use but bar “representing that the User Output is entirely human generated”. No clause covers the stock avatar library, so the terms do not say whether stock avatars may run in ads. JoggAI states 50+ languages.

Best for

High-volume talking-avatar output on a small budget, and teams that want the same credits in the web app, the API and agent tools.

Not for

Buyers who want refunds, which the terms rule out, or a firm price for generative output, which Jogg only approximates, and for premium AvatarX, which Jogg does not publish.

Argil: an ad read by your own verified clone

Argil turns your own verified clone into a presenter. The terms require “the compulsory in-depth identity verification process for Platform Users” before a User Avatar video is accepted (5.2.3.1). For a founder-led ad, that is the consent Synthesia’s AUP asks of a custom avatar, built into sign-up.

Pro lists $50 a month for 2,000 credits (pricing page). Its docs give two rates for 30 seconds, so a 30-second ad costs $2.00 to $2.25.

Argil’s generic avatars come from people under contract with it, but the terms do not say whether they may appear in paid ads (5.2.3.2). No language count is published.

Best for

Founder-led and personal-brand videos where your own verified clone reads the script, with B-roll assembled in the same tool.

Not for

Performance teams that want an actor library built around ad formats, or anyone who needs credit rates confirmed for the current plans.

Captions: talking ads made on a phone with your AI twin

Captions is a phone-first app for talking videos, AI twins and captioned edits; its pricing page says “Features and prices reflect iOS plans only”. That makes it the alternative for an iOS workflow.

Its app terms (4 September 2025) bar commercial use of Mirage content without Mirage’s written consent (3.1(xiv)). They do not say whether that reaches an ad made in the app. Captions on web is the plain route: its separate terms license output “for advertising or other purposes” (1.2).

On Max at $24.99 a month, a 30-second Prompt to Video ad costs $4.00 (pricing page). Prompt to Video works in 39 languages. Captions alternatives covers the app’s own replacements.

Best for

Business teams making avatar ads on Captions on web, whose terms name advertising, and phone creators captioning and editing their own footage.

Not for

Scripted testimonial ads, since its policy bars input that does not reflect your honest views. Also regulated verticals it bans, and anyone who wants extra credits without upgrading.

Creatify: product ads from a URL, billed in 15-second blocks

Creatify turns a product URL or script into avatar ads, and its plan table lists an Ad Launcher for Meta, TikTok and AppLovin. Starter lists $39 a month for 100 credits, and avatar video bills 5 credits per 15 seconds, rounded up (pricing page). A 30-second ad costs $3.90.

On stock actors the documents split. Its AI avatar page FAQ places commercial rights in “all paid subscription plans (Starter, Pro, and Enterprise)” and mentions paid advertising campaigns. The terms license “Community Assets” for commercial use (6.3) without saying the AI actors are among them. The matrix reads stock actors in ads as unclear.

Creatify states 75+ languages on its pricing page and 29 in its FAQ. Creatify vs Synthesia sets the two side by side.

Best for

E-commerce teams making URL-to-video ads in volume who want an ad launcher for Meta, TikTok and AppLovin in the same tool.

Not for

Buyers who need predictable spend on the agent features, whose credit use is not known upfront, or more than one seat below Pro.

Left out, and why

D-ID bars ads on its trial (EULA 3.1) and on its paid Lite plan (20.2). On Pro, its EULA does not say whether stock avatars may run in ads. Every animation carries a synthetic mark you may not remove without written approval (4.2).
