Best for voiceovers and video ads from one subscription
Synthesys sells an AI voice generator and a video agent for marketing teams, from $20 a month billed yearly. There is no free plan or trial. Refunds stop after 3 days, and the product has moved toward video ads, so voice-only buyers pay for tools they may not use.
Who Synthesys is for
- Fits if you make voiceovers and video ads for marketing
- Makes sense if you want a few seats and scheduled posting on one bill
Who Synthesys is not for
- Not for you if you want to try it first, because there is no free plan or trial
- Skip it if you only need voiceover, since the focus has moved toward video ads
- Watch out: refunds end after 3 days and need 25% or less of credits used
- Pricey if you add seats: Agency is $83 a month for 3 seats
Why Synthesys gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyStarter is $20 a month yearly ($29 monthly) for 3,500 credits and one seat. That is in the dearer quarter of the category, and Pro is $41 and Agency $83.
- FFree plan and trialNothing free. The pricing page lists no plan or trial, and refunds apply only within 3 days and if you used no more than 25% of your credits.
- CFeaturesVoiceover and music cost no credits, while video and image generation spend them, with brand kits, autopilot workers and social publishing on higher plans. A marketing job more than a voice job.
- CEase of useNo store rating on record. Credits and autopilot workers mean there is something to learn.
- BPlatforms and integrationsWeb, with TikTok, Instagram and Facebook publishing listed. No apps.

Keep Synthesys, or make your own?
Keep it
To replace Synthesys you would be making a voice model, which you can rent by the minute but not make. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 36 of the 43 other AI voice generators grade higher. It costs $240 a year.
What you could not
- A voice model, which you can rent by the minute but not make.
- A voice model trained on your recordings.
- A video model, which you can rent by the second but not make.
- An AI agent, with the models and the safeguards behind it.
What this rests on. Synthesys’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Synthesys?
Synthesys began as a text to speech and avatar tool and now sells an AI video agent that turns a brief into finished ads and short videos. Its voice generator covers text to speech, voice design, cloning and speech to speech, all sold under one credit-based subscription.
Worth knowing
- The pricing page lists no free plan or trial; plans are paid from the start.
- Refunds are limited to 3 days after purchase and to accounts that used no more than 25% of their credits.
- Plans are measured in credits that video and image generation spend; the page says voiceover and music never cost credits.
- The product's focus has moved toward video ads, so voice-only buyers pay for tools they may not use.
Key features
- Text to speech library
- The voice generator page lists 400+ voices in 140+ languages, with a voiceover studio of 20 narrators.
- Voice design and cloning
