About

What is Synthesia

Synthesia converts written content — scripts, decks, PDFs, websites — into videos using AI avatars and voiceovers, removing the need for cameras, actors, or production crews. It's built for marketing teams and GTM leads at SMBs and mid-market companies that need to produce training, sales enablement, or communications content at volume. The standout capability is voice cloning paired with lip-synced dubbing into 80+ languages, which lets a single video asset reach global markets without re-recording. Teams can collaborate in real time, apply brand colors and fonts, and push content through Salesforce or Zapier-connected workflows. The honest limitation: Synthesia is a video creation and localization tool — if you need deep scriptwriting assistance or AI-generated copy at scale, you'll want a dedicated copywriting layer alongside it.

Our verdict

Vanderbuild take

For marketing and GTM teams that need to produce video content without a production budget, Synthesia is one of the more practical options in the AI video space — it handles the full loop from script to localized, branded output. On the agentic side, the API is available and capable enough that you can wrap it into your own automation layer or MCP stack; it's not a native MCP server, but solid REST access means you can trigger video generation programmatically from your existing workflows. Pricing starts free with no credit card required, and the $29 Starter tier is accessible for small teams — though video minute limits will push you toward Creator ($89/month) faster than you'd expect if you're producing at any real volume. The core limitation to flag: Synthesia is a video production and localization tool, not a copywriting engine — the AI assists with video generation, but if your team needs AI-drafted scripts or copy at scale, you'll need to bring that capability from elsewhere.
