Synthesia Review for SMBs

video tool · $22-$89/mo + enterprise

Synthesia converts written scripts into polished video with AI-generated avatars speaking in 120+ languages. It's built specifically for training videos and internal communications where you need to produce dozens of videos quickly without hiring actors or crews. The catch: it's best suited to instructional content, not brand storytelling or marketing.

What it does

You paste a script into Synthesia, pick an avatar (corporate-looking presenter types), select a language, and the platform generates a video with lip-synced speech and basic backgrounds. You can customize colors, add logos, upload slides, and adjust pacing. The output quality is professional enough for internal training—think HR onboarding, compliance modules, or product walkthroughs. Synthesia handles the voiceover generation, avatar animation, and rendering; you don't need a camera, microphone, or editing software.

Who it's for

✓ Ideal user

L&D teams and internal communicators who need to produce 5+ training or onboarding videos per month and want to bypass hiring freelance videographers or voiceover talent. You'll see ROI fastest if your team currently writes training scripts but waits weeks to get them filmed.

✗ Not for

Marketing teams shooting brand campaigns, product launches, or anything requiring real-world footage, emotional storytelling, or customer testimonials. If your audience expects cinematic quality or human faces, this tool will feel robotic.

Typical team size

5–500 employees. Solo owners rarely need this; enterprises often have video production in-house.

Pros

✓ Avatar lip-sync is genuinely credible at normal playback speed, making videos feel produced rather than AI-generated. Most viewers won't notice the difference from real video, which matters if you're training external partners or regulators.

✓ 120+ language support with native-accent voiceovers saves massive time if your company operates globally. You write once in English, hit a button, and get the same video in Mandarin, Spanish, and Japanese without hiring translators or voice actors.

✓ Turnaround time is minutes, not weeks. A 10-minute training video that would take a freelancer 2–3 weeks costs you 30 minutes of script writing and avatar selection.

✓ Pricing scales with usage, not seats. Unlike video software that charges per user, Synthesia charges per video or minutes generated, so a 50-person team pays the same as a 5-person team if they produce the same volume.

Cons

✗ Avatar selection is limited and generic. You get corporate presenters in suits and business casual—no customization of appearance, age, or ethnicity beyond Synthesia's preset library. If you want your CEO to deliver the training, you can't replicate them.

✗ Output quality drops noticeably for complex scripts with technical jargon, heavy accents, or unusual sentence structure. Lip-sync glitches and unnatural pauses become obvious, especially in languages with tonal or phonetic complexity.

✗ No real editing after generation. If your script needs a sentence moved or rephrased after you see the video, you have to regenerate the whole clip. This creates friction if you're iterating with stakeholders on messaging.

Pricing breakdown

$22/month (starter: ~10 minutes/month)

Synthesia uses a credit-based system: lower tiers give you minutes of video generation per month at fixed prices, while enterprise plans negotiate volume and custom avatars. Most SMBs land in the $22–$89/month range depending on output volume.

Where it gets expensive

Beyond 50 minutes per month, you're into the $89/month tier. Enterprise plans with custom branding, private avatars, or bulk discounts require a sales call and can run $500+/month.

Alternatives worth considering

InVideo
video
Rapid AI video creation for solo creators, small marketing teams, and social content.
InVideo is cheaper ($15–$60/month) and more flexible for marketing and social content, but produces lower-quality AI avatars. Pick InVideo if you need volume on a tighter budget and don't mind less polished presentations.
Murf AI
ai voice
Professional AI voiceovers for marketing videos, training, and e-learning.
Murf AI specializes in voiceover and text-to-speech with 120+ languages, similar to Synthesia's voice engine. Use Murf if you already have video footage or slides and just need to add professional voiceovers without avatar animation.
Pictory
video
Turns long videos and articles into short, captioned social clips automatically.
Pictory turns blog posts and long-form content into short videos using stock footage and text overlays, not AI avatars. Choose Pictory if your training material is already written and you want quick clips for social or internal sharing without the avatar component.

Verdict

Synthesia is genuinely useful if you're running an L&D function or internal comms team that produces training videos regularly. It cuts production time from weeks to hours and eliminates hiring costs for freelance videographers and voice talent. However, it only works well for instructional content—anything requiring emotional impact, brand personality, or real human faces should go elsewhere.

Worth it when

Your team produces 5+ training videos per month, works in a regulated industry (finance, healthcare, compliance), or operates globally and needs the same message in multiple languages fast. You'll recoup the subscription cost in your first month if you'd otherwise pay a freelancer $1,000–$2,000 per video.

Skip when

You produce fewer than 2–3 videos per month, need custom branding with real people, or rely on emotional storytelling or customer testimonials. The per-video cost ($10–$20 after platform fees) beats freelancers only at scale.

FAQ

Can I use my own voiceover instead of AI?▼

No. Synthesia generates the voiceover from your script automatically. If you need to use a real person's voice, you'd have to record separately and use another tool to sync it to the avatar—defeating the purpose of using Synthesia.

How much does a typical training video cost to generate?▼

A 5-minute video uses roughly 5 minutes of your monthly credit allowance. On the $22/month plan (10 minutes/month), one 5-minute video uses half your budget. On the $89/month plan (100 minutes), it costs about $4.45 in credits. Most SMBs find they need the $45–$89/month tier to stay under limits.

Can I customize the avatar to match my brand?▼

Synthesia's avatars are presets on the base plans—you can't create a custom likeness without upgrading to enterprise (which requires a sales call). You can add your logo, choose colors, and use branded backgrounds, but the presenter is always a generic AI face.

How do I use videos made with Synthesia if I have a global workforce?▼

Export as MP4 and upload to your LMS, intranet, or video platform (YouTube, Vimeo, Teams, etc.). Synthesia integrates with a few LMS platforms like Cornerstone and SAP SuccessFactors, but for most tools you'll just download and host manually. Subtitles are auto-generated for accessibility.
