Synthesia Review

Prompt 1 — Employee Onboarding Video

Prompt: “Create a 2-minute onboarding video for new software developers. Use a professional female avatar with a friendly tone. Cover the company mission, team structure, the first-week checklist, and how to access the developer portal. Include text overlays for key dates.”

This is one of Synthesia’s most natural use cases because the platform handles structured, multi-section business content very well. The delivery stays clear, the avatar performance is stable, and text overlays fit naturally into this type of training or onboarding format. That matters because onboarding videos do not need dramatic emotional performance. They need clarity, consistency, and the ability to update quickly later. That is exactly the kind of content Synthesia is built around. The company’s main site and features pages also make this positioning pretty clear: business video, training, support, and internal communication are the center of the product, not side categories.

Prompt 2 — Multilingual Sales Intro

Prompt: “Create a 60-second product introduction video in English with a confident male avatar. This video will be translated to Spanish, German, and Japanese. Write a clear, simple script that works well across all four languages.”

This is where Synthesia becomes much more compelling. The video translation workflow is one of its strongest practical advantages. In practice, the main win is not just dubbing. It is that the same avatar and same structure carry over into the translated versions, which keeps the whole content library more consistent. For global teams, this is often the feature that changes the economics of video production the most. One video can become many without rebuilding the whole thing manually.

Prompt 3 — Internal HR Announcement

Prompt: “Make a 90-second video announcement about our new flexible work policy. Use a warm, approachable female avatar. The tone should be supportive and clear. Include a call to action at the end directing employees to the HR portal.”

Synthesia is good at this kind of internal communication because the avatars are calm, controlled, and professional by default. In many contexts, that is a strength rather than a weakness. HR policy videos, process updates, and internal notices usually benefit more from consistency than from personality. The branding layer also helps here. Synthesia supports company visuals, templates, and layout structures that make the output feel like part of an existing communication system rather than a random generated clip. The limit is emotional nuance. If the message depends heavily on personal warmth or leadership presence, a custom avatar or a real person on camera may still land better. But for routine internal communication, this workflow fits very well.

Prompt 4 — Product Tutorial With Screen Recording

Before using this prompt: Upload the screen recording first, then write the script around the actual product steps.

Prompt: “Create a 3-minute tutorial showing how to use our invoice management feature. Add an avatar on the left side explaining each step, with the screen recording displayed on the right. Use a calm, professional tone.”

This is one of Synthesia’s most practical business outputs because it combines presenter video with software walkthrough structure. The split layout is familiar, easy to follow, and a good fit for SaaS tutorials, knowledge-base videos, onboarding modules, and internal tool training. The work here is less about whether Synthesia can generate the content and more about whether you line up the script pacing with the on-screen action. That is where the editing time usually goes.

Prompt 5 — Customer Support FAQ Video

Prompt: “Create a 2-minute FAQ video answering the question: ‘How do I reset my password?’ Use a helpful, patient avatar. Include step-by-step text overlays. The tone should feel reassuring and easy to follow.”

This is another strong fit because the platform is built for repeatable, scalable, process-driven video. Support videos are often formulaic in a good way. They need to be clear, consistent, and easy to update. Synthesia handles that well. The same workflow can be repeated across dozens of help-center questions without changing the production setup much. That is important because one of the biggest real-world advantages of Synthesia is not just generating one video quickly. It is generating many similar videos without the usual production friction.

Prompt 6 — Social Presenter Clip

Prompt: “Create a 30-second LinkedIn video. Use a charismatic male avatar with a modern look. Topic: ‘Three tips for remote team productivity.’ Energetic and conversational tone. Include a text callout for each tip.”

Synthesia can do this, but this is also where you start to see its limits more clearly. Business-social content works better than creator-social content here. The output is clean, readable, and polished, but stock avatars still stay fairly controlled in their movement and emotional range. So for a company page, a B2B social clip, or a branded thought-leadership format, this is useful. For personality-driven creator content where the whole point is natural charisma and spontaneity, it feels more restrained. It is a business video tool first.

Prompt 7 — Personal or Studio Avatar With Voice Cloning

Before using this prompt: Record a clean voice sample and create a personal avatar, or use a studio avatar if your plan and workflow support it.

Prompt: “Create a welcome message for our annual sales conference using my custom avatar and cloned voice.”

This is where Synthesia becomes much more compelling for leadership communication and branded presence. Personal avatars and studio avatars make it possible for a recognizable speaker to scale communication across many markets and repeated messages without constantly stepping on camera. This is also one of the clearest cases where version or engine details matter: Synthesia’s newer avatar system is built around its Express engines. Express-2 Avatars are positioned as the newer generation designed for fuller-body, more expressive speaker performance, while EXPRESS-1 is tied to studio-avatar performance. That tells you Synthesia is actively improving avatar realism and gesture quality as a platform-level engine, not just adding more avatar faces to the library.
