D-ID vs Synthesia

Synthesia publishes a cheapest paid plan at $29/mo, or $18/mo billed annually, with 14,500 credits included per year, giving a small team a real number to budget against. D-ID does not publish a comparable price on its site. Synthesia's free plan is capped at 1,200 credits per month, a concrete quota, while D-ID's trial plan instead adds a full screen watermark across all output, a harder limit for anyone trying to share a clean sample. Both tools do watermark free plan output, so that part is even. With a published entry price, a published annual price, and a published free tier cap, Synthesia gives budget conscious buyers far more to work with than D-ID.

Both D-ID and Synthesia support interactive, conversational avatars that answer back in real time, and both expose a public API, so either can anchor a live avatar stack. Voice cloningvoice cloning - Creating a synthetic copy of a specific person’s voice from recorded audio samples. is included on both as well. The gap shows up in the specifics: Synthesia names an ElevenLabs partnership with a native in-product voice library for text to speech, while D-ID only references hundreds of unnamed options. Synthesia also names its avatar rendering, Express, where D-ID does not name its model on its marketing pages. Since the core real time capability and API access are even between the two, these more concrete, named integrations give Synthesia a slight edge for a team choosing a conversational avatar foundation.

Both D-ID and Synthesia offer a public API. Synthesia publishes how that API is priced, included and not metered separately on its Creator plan and above, giving a developer a clear cost model. D-ID does not publish comparable API pricing. Synthesia also names a verified ElevenLabs partnership for text to speech, while D-ID only references hundreds of unnamed options. On output rights, Synthesia states the customer will own all customer data, while D-ID restricts its cheapest paid tier, Lite, to non commercial use. D-ID does match Synthesia on interactive avatar support, so that is even. For a team weighing documented pricing and clean output rights before integrating, Synthesia is the stronger pick.

Synthesia publishes a cheapest paid plan at $29/mo, giving marketers a real figure to work out cost per variant. D-ID does not publish a comparable price on its site. Synthesia also lists a stock avatar library that scales with plan, 125 plus on Starter up to 240 plus on Enterprise, useful for testing many hooks, while D-ID publishes no stock avatar count at all. Both tools support batch and CSV personalization for generating variants at volume, and both watermark free plan output, so those two are even. Both also support video translation and dubbing. With a published entry price and a published, tiered stock avatar library, Synthesia gives performance marketers clearer economics for testing ad hooks at scale.

Both tools cover the core mechanics of personalized outreach: D-ID and Synthesia each support batch and CSV personalization, each can build a custom avatar from a rep's own footage, and each offers a public API. With those tied, price and length break the tie. Synthesia publishes a cheapest paid plan at $29/mo, while D-ID does not publish a comparable figure, leaving sales teams unable to budget against it. Synthesia also allows up to 150 scenes per video, each up to 5 minutes, far more room for a longer personalized pitch than D-ID's flat 5 minute cap. On the specifics that are actually published and comparable, Synthesia edges ahead.

Synthesia publishes SCORM and LMS export support, letting a course land directly in a corporate learning system. D-ID does not publish anything on SCORM or LMS export, a real gap for this use case. Both tools support video translation and dubbing, so multilingual course rollout is even. Synthesia also publishes 60 plus video templates to start courses from, where D-ID publishes no template count. On usage rights, Synthesia states the customer will own all customer data, while D-ID's cheapest paid tier, Lite, is restricted to non commercial use, a concern for an audited corporate rollout. Synthesia also publishes an annual entry price of $18/mo, while D-ID publishes none. Synthesia covers every published requirement for this use case and D-ID is missing most of them.
