What Synthesys really costs
Synthesys bills in monthly credits, and it is unusually open about what things cost: its pricing page publishes a per-format table for a 15-second video at standard quality. A 15-second UGC ad is about 400 credits, a TV-commercial-style spot about 647, an explainer about 300, and a faceless story only about 30 — while scripts, voiceover, music and agent chat cost no credits at all. On annual Starter ($240/year for 3,500 credits a month, 42,000 a year), one credit works out at roughly $0.0057, so a 15-second UGC ad costs about $2.29 in credits.
The cards below use that UGC ad — the format most buyers come for. Because the app quotes every video before you approve it and failed generations are free, the multiplier that matters is revisions you choose to make, not failures you suffer.
$2.29
per 15-second UGC ad on annual Starter — approved first time
$4.57
per 15-second UGC ad if you regenerate it once
$6.86
per 15-second UGC ad at three generations
Derivation: annual Starter is $240/year for 3,500 credits/month ($240 ÷ 42,000 credits ≈ $0.0057 per credit); Synthesys's pricing page lists a 15-second UGC ad at about 400 credits, so 400 × $0.0057 ≈ $2.29. Other formats differ — faceless stories are about 30 credits, TV commercials about 647. Figures from Synthesys's official pricing page, checked Nov 2026.
What is Synthesys?
Synthesys began as a suite for small businesses that combined AI voice generation with avatar spokesperson videos, so a marketer could buy narration and an on-screen presenter in one place. That bundle is where it started — AI voices, talking avatars, a text-to-speech library across many voices and languages, and marketing templates. Its current pricing page shows the product has widened: Synthesys now leads with a video agent that takes a brief and returns finished videos in formats from UGC-style ads to explainers and faceless stories, with studio tools for images, clips and voiceover alongside.
The positioning matters for who should buy it. Synthesys is not chasing the most realistic avatar or the most beautiful voice in isolation; category leaders beat it on each single craft. Its offer is coverage and convenience for a small marketing team — script, voice, presenter, visuals and even publishing from Agency upward — under one bill, with full commercial rights stated on every tier. If your bottleneck is producing lots of serviceable marketing video rather than one flawless piece, that trade makes sense.
How Synthesys works
- 1Choose a plan by credit volume — Starter's 3,500 monthly credits are the entry point; there is no free plan to trial first.
- 2Brief the video agent in chat, or start from a product page or an existing ad URL you want to recreate, choosing from the formats on offer.
- 3Review the script and storyboard the agent proposes before any credits are spent — the pricing page stresses this review step.
- 4Let it generate the video with voiceover, music and captions included, then use the studio tools to adjust clips, images or narration.
- 5Check the credit quote for any regeneration: the app shows the exact price of each video before it is made, and failed generations cost nothing.
- 6Download the MP4; on Agency and Max plans you can also publish and schedule directly to social platforms.
Core features
Video agent, brief to finished video
Describe what you need and the agent builds the video, with a script and storyboard review before generation. According to the pricing page, every plan includes the full agent and all 11 formats.
AI voices and voiceover studio
The suite's original strength: text-to-speech and voiceover tools across many voices and languages, with scripts, voiceover and music included without extra credit cost on the current plans.
Avatar spokesperson videos
Stock AI avatars and presenter-led formats — including AI presenter sales and YouTube videos — for businesses that want a face on screen without filming anyone.
Ad recreation from a URL
Point the tool at a competitor's ad or your own product page and have it build a video from it — a workflow aimed at performance marketers who iterate on proven formats.
Brand Kit and ads library (higher plans)
Pro unlocks the Brand Kit — logos, colors, products and end cards applied across videos. Agency adds a winning-ads library with competitor tracking, per the pricing page.
Publishing and scheduling (Agency up)
Finished videos can be published and scheduled to TikTok, Instagram and Facebook from inside the app on Agency and Max plans, without spending credits.
The free plan — the full truth
There is no Synthesys free plan, and this review will not pretend otherwise: our listing classifies it as a paid product, and its pricing page starts at the paid Starter tier. What you get instead of a free tier is a low-commitment entry — Starter is the full product, not a cut-down demo, with the complete video agent, all formats and full commercial rights from the first month.
Synthesys does offer a safety net that partly replaces a trial: according to its pricing page, you can get a refund within 3 days of purchase if you have used no more than 25% of your plan's credits. That is a short window — use it deliberately, generating your real test videos in the first days rather than browsing templates.
- • No free plan and no free trial tier (listing and pricing page agree)
- • Entry is Starter at $20/month billed annually ($29 billed monthly)
- • Refund window is 3 days and capped at 25% credit use, per the pricing page
- • Plan credits reset monthly; only separately bought credit packs never expire
- • Brand Kit starts on Pro; the ads library and publishing start on Agency

Synthesys alternatives
See all alternatives →The first alternative in this category is HeyGen, the better pick when the avatar presenter is the product — more expressive presenters and strong translation for customer-facing video. D-ID is the cheaper specialist for talking-head work, animating a photo into a presenter with a well-regarded API. Fliki is worth comparing for script-to-video with voiceover, where the workflow is simpler and the focus is faceless content. Choose Synthesys when you want all of these jobs under one bill with commercial rights included, rather than the best single instrument.
HeyGen
HeyGen turns a script into a video of a realistic digital presenter, with a large avatar library, voice cloning and translation features. It is widely used for marketing videos, product explainers and social content where a human-like presenter is needed without filming.
D-ID animates a still photo or avatar into a speaking presenter and is well known for its API, which businesses use to generate personalized talking videos at scale. It also offers a studio for individual creators making presenter content cheaply.
Fliki converts text into videos with AI narration from a large voice library, matched stock visuals and captions. It is aimed at creators and marketers who want narrated videos in many languages without recording anything themselves.
