A user starts with a prompt, script, document, PowerPoint file, public URL, or uploaded video, then selects an avatar, voice, layout, language, and visual assets. The user edits scenes and scripts in the browser, generates the video, and can download it, publish it, embed it, translate it, or automate the workflow through the API.
What is Synthesia?
Synthesia is a web-based AI video creation platform built mainly for business communication and learning content. Rather than functioning as a general-purpose chatbot or a traditional video editor, it combines script-to-video production with AI presenters, synthetic speech, templates, brand controls, localization, and publishing tools.
A typical project starts with a script, prompt, PowerPoint presentation, document, public URL, or existing video. The user selects an avatar and voice, arranges scenes in the browser, adds visual assets and captions, and generates the finished video. The result can be downloaded, published, embedded, translated, dubbed, or produced through the API.
How Synthesia is used
Synthesia is most useful when an organization needs to create or update many structured videos rather than produce one highly customized film. A learning team might convert training material into presenter-led lessons, while HR could create onboarding or compliance videos that are easier to revise than filmed footage. Sales and marketing teams can use it for product explainers, customer education, and localized presentations.
Users can import PowerPoint files and other supported documents, or begin with a prompt and build the content scene by scene. The browser editor provides layouts, avatars, voices, captions, motion graphics, templates, and generated media. Existing videos and YouTube-linked content can also be translated and dubbed for other audiences.
Avatars, voices and localization
AI avatars are central to Synthesia's workflow. Projects can use stock presenters, personal avatars, or custom avatars, depending on the plan and workflow. Synthetic voices provide narration in many languages, and supported workflows include consent-based voice cloning. Video creation and voice features cover more than 160 languages, while AI Dubbing supports more than 130; exact availability depends on the avatar, voice, cloning option, dubbing workflow, and plan.
Dubbing and translation make Synthesia particularly relevant to organizations distributing the same training, enablement, or communications content across regions. These tools reduce the need to record separate versions, although organizations should still review translated scripts and generated pronunciation before publishing important material.
Editing, interactive content and workflow controls
Synthesia is not intended to replace a full professional film-editing suite. Its editor is optimized for scenes built around scripts, presenters, layouts, and business visuals. It supports templates, Brand Kits, captions, calls to action, quizzes, branching scenes, and other interactive elements. Interactive and roleplay content can be useful for training and practice scenarios, while publishing and analytics help teams distribute and evaluate content.
Collaboration features, shared workspaces, organization administration, permissions, analytics, and SSO are especially relevant to larger teams. The platform also supports LMS and content workflows through integrations and embeds. Documented connections include PowerPoint, Articulate 360, Docebo, SAP Litmos, Workday, Zapier, BambooHR, 360Learning, and other learning, HR, commerce, localization, and content platforms.
API and automation
Organizations that need repeatable production can use the Synthesia API to create videos programmatically. Webhooks provide notifications for processing events such as completion or failure, allowing generated videos to be connected to internal systems and publishing workflows. This is more useful for teams producing content at scale than for an occasional individual video creator.
The API and automation capabilities distinguish Synthesia from simpler avatar-video tools, but they do not turn it into a general workflow or agent platform. The main automation target remains video production and delivery.
Pricing and credits
Synthesia has a free Basic plan that does not require a credit card. It includes 1,200 credits per month and can produce approximately 10 minutes of video or equivalent usage, but free output is watermarked and feature access is limited.
Paid self-serve access currently starts with the Starter plan at $29 per month when billed annually. Creator is listed at $89 per month when billed annually. Enterprise pricing is custom and adds broader administration, shared workspaces, SSO, expanded avatar access, and higher API limits.
Pricing is usage-based rather than determined only by the number of projects. Basic and Starter include 1,200 credits per month, while Creator includes 3,600 credits per month under the relevant monthly allocation. Video generation uses two credits per second, and dubbing, API usage, AI assets, and avatar-related features can consume credits at different rates. Credits reset each billing period and unused credits do not roll over, so high-volume teams should estimate usage before selecting a plan.
Who is Synthesia best for?
- Learning and development teams: Create onboarding, instructional, compliance, and internal training videos that can be revised without reshooting.
- Sales and enablement teams: Produce product explanations, demonstrations, and localized enablement material.
- HR and corporate communications: Deliver employee announcements, policy explanations, and recurring internal updates.
- Marketing and customer education teams: Build presenter-led explainers and multilingual content without a traditional production setup.
- Enterprise content operations: Connect video production to internal systems through the API, webhooks, embeds, and integrations.
Synthesia is less suitable for projects that depend on live-action footage, detailed physical demonstrations, cinematic control, or extensive frame-by-frame editing. A conventional production workflow may be preferable when physical environments, real people, or precise visual continuity are central to the result.
How it differs from adjacent AI video tools
Synthesia focuses on structured presenter-led business video. That makes it different from an AI video and image generation platform such as Runway, which is oriented more toward generative visual creation, and from a text-based editing tool such as Descript, which centers on editing recorded audio and video through transcripts. It also overlaps with avatar-video services such as HeyGen, but the important evaluation criteria are the same: avatar and voice quality, localization, editing flexibility, credit usage, integrations, collaboration, and enterprise administration.
Compared with a general-purpose AI assistant, Synthesia is specialized. Its value comes from turning structured content into distributable video rather than from open-ended research, conversation, coding, or document analysis.
Privacy, security and practical limitations
Synthesia is a multi-tenant SaaS platform using AWS infrastructure. Its documentation describes logical customer-data segregation, AES-256 encryption at rest, access management, audit logging, penetration testing, and security certifications and frameworks including SOC 2 Type II, ISO/IEC 27001, ISO/IEC 27701, ISO/IEC 42001, and GDPR-related controls. Enterprise deployments can use SSO and organization-level administration.
Customers should review the applicable terms and configuration when using sensitive scripts, recordings, personal avatars, or cloned voices. Synthesia documents controls for AI-assisted content generation, but the precise treatment of customer content for model training can vary by service, agreement, and configuration. Customer data may be deleted following a request, with documentation indicating that deletion can take up to 90 days and that residual backup copies may remain temporarily.
The full editing experience is designed for desktop or laptop browsers. Limited mobile-browser access is available for some self-serve users, but the full editor is not available on mobile, and mobile use is not currently supported for Enterprise users. The principal trade-off is convenience and scalability versus granular production control: Synthesia can accelerate repeatable business video creation, but its credit system, plan restrictions, and presenter-led format may not suit every project.
Is Synthesia a good fit?
Synthesia is a strong fit for organizations that regularly create training, onboarding, enablement, internal communications, product education, or multilingual business videos. It is particularly useful when content changes frequently, when several language versions are required, or when a team wants to avoid filming for every update.
It is a weaker fit for filmmakers, creators seeking highly individualized cinematic control, and teams whose content depends on real-world demonstrations. Prospective users should test avatar and voice quality with representative scripts, calculate expected credit consumption, and confirm that the required integrations, languages, collaboration controls, and privacy terms are available on their chosen plan.
