Our verdict
D-ID and Synthesia both make AI videos with talking presenters, but they aim at different jobs. D-ID turns a single photo or avatar into a talking video and also offers real-time conversational avatars and an API, so it suits people building interactive or custom avatar experiences. Synthesia turns a written script into a polished presenter video for business use, with team features, brand kits, and many languages, so it suits training and corporate teams.
Pick D-ID if you want to animate a photo or build a live, interactive avatar that talks back, or you need an API to add avatars to your own product.
Pick Synthesia if you need script-based presenter videos for corporate training or multilingual explainers and want shared team workspaces and brand templates.
