# Hoctav vs HeyGen

HeyGen excels at marketing avatar videos and translation. But to train your teams, teaching and confidentiality change everything.

## What HeyGen is

HeyGen is an AI avatar platform very popular for social content, marketing and video translation. Like Synthesia, it is a high-performing video _generator_, geared towards communication rather than training.

## Angle 1 — Sovereignty & GDPR

HeyGen is an American publisher: your data travels outside the European Union. Hoctav guarantees [European hosting](/en/hebergement-europe/) and draws on **your corpus** without disseminating it. A critical point for internal training and regulated subjects.

## Angle 2 — Fit for training

HeyGen produces embodied, multilingual videos, but does not structure the teaching. Hoctav applies genuine instructional engineering — [M.E.R.E.](/en/methode/structure-mere/), [F.A.B.](/en/methode/methode-fab/), targeting the learner — and lets you make [your own expert the speaker](/en/methode/).

## Angle 3 — Effort ↔ output relevance

On HeyGen, getting a genuinely instructive video means scripting it yourself upstream. Hoctav builds in that scripting: you supply the knowledge, the platform produces a structured, instructional module — for minimal effort.

> "I use HeyGen too: it doesn't hold a candle to Hoctav on video quality and length — often limited to 4 to 15 seconds, whereas with Hoctav I make 5-minute videos."

— Ludovic K., consulting engineer (nuclear industry), also a HeyGen user
