Synthesia

Synthesia Ltd.

Synthesia helps you create professional AI videos from text using virtual avatars and voiceovers.

What is Synthesia?

Synthesia is a cloud-based platform that enables users to create AI-generated video content with lifelike avatars and voiceovers — without needing cameras, actors, or a traditional production studio.
In other words: you input text (or a script), select an avatar (or create one), choose style/voice/language, and generate a video that looks & sounds professional.

Between its features, workflow support (create → collaborate → publish), and enterprise-grade security, the platform positions itself as the “#1 AI video platform for business”.

Key Features & Capabilities

Here are the major features of Synthesia, drawn from their website and documentation:

  • AI Avatars: Choose from a large gallery of pre-built avatars (human-looking presenters) that can deliver your script. Users can also create custom avatars (digital twins) using their own likeness.
  • Text-to-Video / Script-to-Video: Enter your script (or upload document/URL) and the system generates the video automatically.
  • Voiceovers in 140+ Languages: The platform supports voice generation (AI voices) in over 140 languages and dialects, allowing localization and global reach.
  • Templates & B-roll / Stock Media Integration: The system includes many video templates, and support for cinematic b-roll and stock footage (for example models such as “Veo 3” or “Sora 2”) in the editor.
  • Branding / Customization: Users can upload their logo, set brand colours, fonts, backgrounds, and ensure that the produced videos are “on-brand”.
  • Localization & Translation: Existing videos can be translated and dubbed into multiple languages, and there is a multilingual player.
  • Collaboration & Version Control: The platform supports team workflows (multiple users, shared workspace), version control (so updates propagate), and analytics to track video performance (views, completion rates, drop-offs).
  • Exports & Integrations: Videos can be downloaded, embedded, or integrated into LMS (Learning Management Systems) via formats like SCORM.
  • Security & Compliance: For enterprise use, the platform is SOC 2 Type II compliant, GDPR compliant, and claims to ensure data security and moderation of generated content.

How It Works (Basic Workflow)

  1. Script creation/input: Type or upload your text, document, or link.
  2. Select avatar and language: Choose a presenter avatar; pick voice/language/dialect.
  3. Customize visuals: Set branding elements (logo, colours), choose template, optionally choose b-roll or stock media.
  4. Generate video: The system synthesizes the avatar speaking the script, adds visuals, audio, etc.
  5. Review & edit: Make changes in the editor, update script or visuals.
  6. Export/publish: Download or embed, distribute via web/LMS/social.
  7. Track analytics: Monitor how users are engaging with the video (views, drop-offs, completion).

Highlights
  • Very fast production compared to filming with actors/studio.
  • Strong localization support (many languages) and brand customization.
  • Good workflow for enterprise (collaboration, analytics, version control).
  • Things to know
  • Some reviews suggest avatars can appear a bit “cold” or less expressive than real humans.
  • There may be constraints on how much “free” video time or usage minutes you get in some plans.
  • While extremely useful for many business use-cases, highly creative or cinematic video production (with full actor movement, camera work, etc) might still be better with traditional filming, depending on the project.
  • AiGanak Analysis

    This tool is specifically for L&D departments and corporate communications teams needing to produce professional training videos with AI avatars. It eliminates the need for expensive studio time and actors, providing a much higher ROI for corporate video than traditional production.
