Synthesia

What it does

Synthesia takes scripts, prompts, PowerPoint files, documents or links and produces finished videos presented by AI avatars, with voiceover, scenes and motion graphics. Existing videos can be translated or dubbed into 140+ languages, keeping the speaker's voice. It also runs interactive avatar Sessions, such as Roleplay for practising hard conversations and Survey for avatar-led interviews that return themes and transcripts.

Teams use it for training, onboarding, sales enablement, internal updates and customer support content. Brand Kits, shared workspaces, approval controls and analytics sit alongside publishing by link, embed or SCORM export. Videos stay updated across embeds when edited. It also offers APIs for video, dubbing and real-time Interactive Avatars, a hosted MCP server for Claude and ChatGPT, and a Syren agent that builds videos from a described brief.

It suits learning, communications and marketing teams who want video without filming, and developers embedding avatars in products. A free Basic plan needs no credit card but is limited to 500 credits a month and adds a Synthesia watermark. Paid plans use a shared credit pool, so heavy use can pause creation until renewal. The editor is desktop-only, and Personal Avatars require a live consent recording.

Example workflows

Turn a policy document into a localised training video

Input: a PowerPoint or document. Steps: upload it to Assistant, choose an avatar and Brand Kit, review the draft, then use 1-Click Translation. Output: finished videos in multiple languages, exported as SCORM for an LMS.

Practise a sales call with a Roleplay Session

Input: a scenario such as a cold call or tough feedback. Steps: create a custom roleplay, share it with learners by link, embed or SCORM, and have them converse with the avatar. Output: real-time coaching and scoring for each learner.

Before you choose

• Credits are shared across video, dubbing, surveys and generated assets, and creation pauses when they run out until renewal or extra purchase
• The free Basic plan adds a Synthesia watermark and does not allow downloads; downloads need a paid plan
• Syren videos cannot be opened in the Synthesia editor, and MCP drafts cannot be edited from the connector
