Synthesia Review

What Is Synthesia?

Synthesia is an AI video platform for businesses that want to create professional-looking videos without filming, microphones, actors, or a traditional production team. It sits primarily in the AI video tools category and is especially useful for training, onboarding, sales enablement, internal communication, product education, and multilingual business content.

The company was founded in 2017 by a team of AI researchers and entrepreneurs from Stanford, Cambridge, UCL, and TUM. Synthesia is now positioned as an all-in-one AI video platform for business users, with tools for creating, localising, managing, publishing, and analysing video content.

For a business user, the main problem Synthesia solves is simple: it reduces the friction of creating repeatable video content. Instead of filming a presenter, recording voiceovers, editing clips, and recreating videos every time something changes, teams can write or import content, choose an AI avatar and voice, generate a video, then update or localise it later.

How Synthesia Works

Synthesia works through a browser-based video creation workflow.

A typical user starts by creating an account, choosing a plan, and opening the video editor. From there, they can start with a template, write a script, use an AI avatar, select a voice, add visual elements, and generate a video. Synthesia also includes an AI Video Assistant that can help turn decks, PDFs, and websites into video drafts.

The basic workflow looks like this:

1. Choose a template, blank project, or imported source such as a deck, PDF, or website.
2. Select an AI avatar, personal avatar, or supported presenter style.
3. Add or generate a script for each scene.
4. Choose voice, language, layout, visuals, captions, and brand elements where available.
5. Preview the video, make edits, and generate the final version.
6. Download, share, embed, publish, or localise the video depending on the plan.

For teams, Synthesia also supports collaboration, branded share pages, embeds, version control, analytics, SCORM export, SSO, and Enterprise governance features on supported plans.

What Synthesia Is Best At

Synthesia is strongest when a business needs repeatable video content at scale.

It is particularly useful for training videos, onboarding materials, SOP explainers, product walkthroughs, sales enablement, customer education, compliance training, and internal announcements. These are areas where the message matters more than cinematic production value, and where the cost of refilming can become a bottleneck.

The platform is also strong for localisation. Businesses that need to explain the same process in different languages can use Synthesia’s multilingual video, translation, dubbing, and caption features to create more accessible versions of the same core content.

Another practical advantage is speed. A marketing manager, learning and development team, agency, recruiter, coach, or operations manager can create a structured video without needing video production experience. That makes Synthesia useful for businesses that need more video content but do not have an in-house production team.

Ease of Use

Synthesia is designed for non-technical users. The workflow feels closer to building a presentation than editing a traditional video timeline. Users can work with scenes, scripts, templates, avatars, voices, and visual assets rather than managing complex footage, audio layers, and editing tools.

The learning curve is reasonable for business users who are already comfortable with slide decks or content tools. The hardest part is usually not the software itself, but preparing a clear script, choosing the right avatar style, and making sure the video does not feel too generic.

For solo users and small teams, the Starter and Creator plans provide a more accessible entry point. Larger organisations will get more value from Enterprise features such as SSO, Brand Kits, collaboration, SCORM export, governance, onboarding, and customer success support.

One important practical note: Synthesia is best treated as a desktop-first creation tool. Mobile users may be able to access demos or simple creation flows, but serious editing and production should be done on desktop.

Output Quality and Performance

For an AI video tool, Synthesia’s output quality is one of its main strengths. The platform offers a large library of AI avatars, natural-sounding AI voices, multilingual support, personal avatars, AI dubbing, captions, templates, and publishing options.

The best results come from scripts that are written for spoken delivery. Short sentences, clear structure, and natural phrasing matter. A script copied directly from a blog post, policy document, or PDF will usually need editing before it becomes a strong video.

Avatar quality is good for training, onboarding, explainer, and internal communication videos, but it is still important to choose the right use case. For emotional brand campaigns, founder-led storytelling, high-end ads, or content where human authenticity is central, real filmed footage may still be better.

Voice and dubbing quality are useful for business workflows, especially localisation, but teams should still review pronunciation, tone, pacing, and terminology before publishing. This is especially important for regulated industries, legal content, financial services, health-related training, or technical product education.

Pricing: Is Synthesia Good Value?

Synthesia can be good value if your business regularly creates training, onboarding, internal communication, product education, support, or multilingual video content. The value is strongest when it replaces repeated filming, manual voiceover recording, or expensive agency production.

For occasional creators, the free Basic plan is a useful way to test the workflow. For individuals and small teams, Starter or Creator may make sense depending on monthly video volume and whether personal avatars, API access, interactivity, and more avatars are needed. Enterprise is better suited to companies that need larger-scale production, governance, SSO, brand control, LMS workflows, and onboarding support.

Pricing changes often. Always check the official Synthesia pricing page before publishing or making a buying decision.

Where Synthesia Falls Short

Synthesia is not the right fit for every video workflow.

The first limitation is creative control. It is excellent for structured, avatar-led videos, but it is not a replacement for high-end editing software, cinematic production, documentary footage, brand films, or social-first creative campaigns where movement, emotion, and visual originality matter.

The second limitation is pricing and usage. Video minutes, credits, personal avatars, higher-quality collaboration features, and Enterprise controls can affect the total cost. Teams producing a lot of video should check usage limits carefully before committing.

The third limitation is realism. AI avatars and voices are improving quickly, but they may still feel less natural than a real presenter in certain contexts. For sensitive announcements, founder messages, personal brand content, or relationship-driven sales, a real human recording may perform better.

Finally, businesses in regulated or trust-sensitive fields should build a review process before publishing. AI-generated videos can be efficient, but legal, financial, health, compliance, and HR content should still be reviewed by qualified people before it goes live.

Best Workflow for Using Synthesia

1. Start with a clear business goal, such as onboarding, training, product education, sales enablement, or internal communication.
2. Turn the source material into a short spoken script instead of pasting long written content directly into the editor.
3. Choose a template, avatar, voice, and layout that match the audience and purpose of the video.
4. Add supporting visuals such as screenshots, diagrams, b-roll, slides, captions, or branded elements.
5. Generate a draft video and review it for pacing, pronunciation, visual clarity, and tone.
6. Ask a colleague or subject matter expert to review the video before publishing.
7. Export, embed, share, or add the video to an LMS, website, internal knowledge base, sales enablement library, or customer support workflow.
8. For important content, track engagement and update the video when the source information changes.

Our Take

Synthesia is one of the strongest AI video platforms for businesses that need scalable, repeatable video production. It is especially useful for training teams, marketing teams, agencies, consultants, recruiters, ecommerce brands, local businesses, and companies that want to turn written content into video without building a full production workflow.

Small businesses should consider Synthesia if they regularly need explainer videos, staff training, customer education, product walkthroughs, or multilingual content. Agencies and consultants can also use it to create client-ready video assets faster, provided they maintain quality control over scripts, branding, and final review.

Larger companies will likely get the most from Synthesia’s Enterprise features, especially if they need SSO, collaboration, SCORM export, brand governance, analytics, localisation, and support for internal video operations.

Synthesia is less suitable for users who want cinematic production, highly emotional storytelling, advanced manual editing, or occasional one-off social videos. Those users may prefer a broader video editor, creative AI video generator, or traditional production workflow.

Overall, Synthesia is a strong AI video tool for practical business communication, especially when speed, scale, consistency, and localisation matter more than cinematic originality.
