Hey everyone! I've been deep in the weeds with HeyGen for a few campaigns now, and I've been using both their native Script Assistant *and* Claude (via the API, mostly) to help generate video ideas and scripts. I'm starting to form some opinions, but I'd love to hear how others are using them.
For me, it boils down to a trade-off between **native convenience** and **strategic depth**. HeyGen's assistant is fantastic when you're already in the flow—it understands the platform's constraints, suggests relevant templates, and gets you a decent first draft fast. But I've found Claude (especially 3.5 Sonnet) is better for the initial brainstorming phase. It can pull in more external market context, suggest A/B test angles I hadn't considered, and structure longer, more nuanced lead-gen narratives.
My current workflow often looks like:
* Using Claude to brainstorm 5-7 core video concepts and hook ideas for a campaign.
* Feeding the strongest concept into HeyGen's Script Assistant to get a structured, platform-optimized first draft.
* Jumping back to Claude to refine the value propositions and CTAs, making them more personalized for different segments.
Has anyone else done a similar comparison? I'm particularly curious about:
* Which tool gives you more *unique* or *surprising* ideas?
* For those using HeyGen's AI Avatars, does the native assistant do a better job with "lip-sync friendly" phrasing?
* Any clever prompt setups for either tool that have become part of your standard ops?
Let's share some notes! The martech stack only gets stronger when we compare workflows.
