Synthesia

What Synthesia does

Synthesia produces presenter video from scripts using synthetic avatars, with a product shaped around corporate requirements rather than social content. It includes a slide-style editor, brand templates, a large avatar and voice library covering many languages, screen recording, translation of finished videos, and a knowledge-connected mode that drafts video content from documents you supply. Access controls, single sign-on, audit trails and content moderation policies are part of the offering, which is why it appears in large organisations producing compliance, onboarding and product training material. It suits learning and development teams, internal communications and support organisations that need to update video content regularly without rebooking a studio. The limitations are cost and range: entry plans cap minutes quickly, the per-seat price is high compared with consumer video tools, and the avatars, while clear and professional, remain better suited to informational delivery than to anything requiring emotional performance.

How to use it

Start at synthesia.io with a free account that lets you generate a small number of short, watermarked videos. The editor works like a presentation tool: each scene holds an avatar, a background and optional slides, and you type the script into a panel beside it. Build the script first in a document, because rewriting inside the editor is slower, and keep each scene to a single idea so revisions stay contained. Choose the voice and language per scene, and use the pronunciation dictionary early for product names and acronyms, which otherwise get mangled consistently across every video you produce. Templates and brand kits are worth configuring before volume production so colours, fonts and lower thirds stay uniform. Two things to plan for: minutes are the billing unit and regenerating a video after a small script change consumes them again, so proofread carefully; and custom avatars require a separate recording process, approval and additional cost on most plans.
