Where UGC Copilot fits
Both are avatar-video platforms, not ad-strategy tools.

For training videos, localization and long-form presenter content, stay with HeyGen or Synthesia.
UGC Copilot: Creator $29/mo (500 credits), Pro $79/mo (1,800 credits), Business $149/mo (4,000 credits); annual billing saves 2 months. No subscription needed: a one-time $9 Starter Pack (180 credits incl. the 50-credit first-purchase bonus) and credit packs from $25 (200 credits). Your first ad build is free, no card required.
