FAQ

Common questions about FastSocial + HeyGen

Is there a pre-built FastSocial + HeyGen automation?

Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches FastSocial and HeyGen's public API docs (or your own uploaded docs) and builds a working automation.

Does this require a pre-built FastSocial or HeyGen connector?

No. The Agent works whether or not FastSocial or HeyGen already has a pre-built connector in Knit's catalog — it researches the real API surface either way.

How long does it take to build?

Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.

Can I turn newly created AI copy into social posts automatically?

Yes, whenever new content or visual renders are finalized in HeyGen, they can be automatically scheduled as posts on FastSocial.

How can AI help manage social media comments in FastSocial?

When a new comment or mention arrives on FastSocial, HeyGen can analyze the text and draft an appropriate reply for your approval.
