FAQ
Does Brainiall do talking-head videos like HeyGen?
Yes, composite flow: base video via Seedance 2.0 or Veo, voice via Brainiall TTS (with voice cloning), lip-sync via Veo Lip-Sync (Q3 2026). HeyGen specializes in talking-head; Brainiall is generalist for any scene.
Why migrate from HeyGen to Brainiall?
4 reasons: (1) $5.99 vs $29 with no cap. (2) Versatility — any scene, not just talking-head. (3) Everything integrated — script (LLM) + voice + video + thumb in one Studio. (4) Compliance — EU-hosted, GDPR, AI Act, DPA auto-download.
How does the quality compare to HeyGen?
For pure talking-head, HeyGen still leads in lip-sync. For general video (product, lifestyle, B-roll, demos), Seedance 2.0 and Veo deliver comparable or superior quality. Creators with diverse needs = Brainiall more versatile.
Does Brainiall do voice cloning like HeyGen?
Yes. Brainiall TTS does voice cloning from 15-60s samples. Also includes Voice Translate (keeps original voice when translating between languages). Difference vs HeyGen: cloned voice can be used in any flow (Seedance video, podcast, audiobook), not just avatars.
Does Brainiall integrate with existing tools?
OpenAI-compatible native. Integrates with LangChain, LlamaIndex, Vercel AI SDK, n8n, Dify, Make, Zapier. /v1/videos/generations async endpoint with polling. Port from HeyGen: change base_url + model=seedance-2.0.
