D-ID lets you feed a script, image, and voice into its API or web interface and get back a finished video of a digital human delivering your message. The core problem it solves is that video content takes time and money to produce at scale—hiring talent, booking studios, managing post-production. D-ID collapses that into minutes and a API call. Pricing starts free (limited credits monthly) with paid tiers around $10–100/month depending on video minutes and API volume; enterprise pricing available on request. The honest limitation: avatars work best for straightforward messaging and explainers, not narrative performance or high emotional nuance.
