Facts checked September 4, 2026
Quick take
Anam's expressive realtime digital-person model for live conversations with image-based avatars, emotion direction, and bring-your-own AI components.
Default recording and enterprise zero-retention are different configurations. Confirm consent, biometric handling, storage duration, concurrency, and the full end-to-end latency before exposing an avatar to customers.
HeyGen's rendered avatar model for producing polished presenter videos from a short identity recording, script, or supplied audio.
This is rendered video, not a realtime digital person. Establish explicit identity and voice consent and confirm avatar eligibility, 4K pricing, queue time, retention, and API engine selection.

Anam says customer session content is not used for training unless separately agreed. Default recordings may be retained for up to 30 days, while enterprise zero-data-retention is available; verify the exact workspace settings.
Provider and API links
Avatar creation involves identity, voice, and consent-sensitive media. The reviewed Avatar V pages do not provide one complete model-specific retention or training-use promise; review current HeyGen consent, privacy, and enterprise terms.
