Frequently Asked Questions

What makes AGC Studio different from other content platforms?

AGC Studio stands out through its 6-report AI research ecosystem — including Viral Outliers, Pain Points, Trending, Evergreen, News, and Daily Trends — which actively analyzes real-world data to inform content strategy. Unlike competitors that schedule posts, AGC Studio generates platform-native content using 88+ format combinations and a 12-node multi-agent blog generator that produces SEO-optimized, schema-enhanced articles in under a minute. Its white-label agency system and AI avatar system with 50+ voices enable agencies to scale client branding without losing identity, while its 50+ specialized AI agents ensure each piece of content is optimized for its specific platform.

Can AGC Studio generate blog posts for my online course platform?

Yes. AGC Studio includes a multi-agent blog generator powered by a 12-node LangGraph workflow with four specialized AI agents: Content, Validator, SEO, and Schema. This system creates publication-ready, SEO-optimized blog posts in 45-60 seconds from either research reports or custom topics. Each post includes auto-generated meta titles, descriptions, keyword optimization, headings, and full JSON-LD schema markup — ready for CMS publishing in four formats: Plain Text, Basic HTML, Schema-Enhanced HTML, or Premium HTML.

Does AGC Studio support multiple client brands for agencies?

Yes. AGC Studio’s white-label agency system allows you to manage an unlimited number of client brands from a single account. Each brand operates in a completely isolated environment with its own Brand Brain, content library, AI avatar, social connections, and analytics. The platform ensures your branding — not AGC Studio’s — appears on all client-facing elements, including connection pages, emails, and redirects. This makes it ideal for agencies managing dozens of course creators or educational brands under one roof.

How does AGC Studio’s AI research system work?

AGC Studio’s AI research system deploys 6 specialized agents that work in sequence to analyze, validate, and compile insights. These agents actively browse the web, pull live data from Reddit, Twitter, Google Trends, and YouTube transcripts, and use 'Triple Validation' to confirm trends across community, social, and search signals. Unlike summary-based tools, AGC Studio ingests full articles (up to 250,000+ characters) and video transcripts (300,000+ characters) to extract complete frameworks. Every claim is traceable to its source, and the system uses real 'Voice of Customer' quotes to ground content in authentic emotional language.

Can I use my own brand avatar in AGC Studio?

Yes. AGC Studio allows you to create and upload custom AI-powered avatars with unique names, personalities, clothing styles, and physical descriptions. Each avatar can be paired with one of 50+ text-to-speech voices and used across all video content formats — including Avatar Videos, Avatar + B-Roll, and Avatar + Img2Vid. The InfiniteTalk video engine ensures razor-accurate lip-sync and natural motion, making your avatar a consistent, recognizable face for your brand across TikTok, YouTube, LinkedIn, and beyond.

Do I need to manually approve every piece of content before it’s posted?

You have full control. AGC Studio offers a flexible automation suite: you can enable 'Manual Approval' to review all AI-generated content in a pending queue before it publishes, or toggle 'Auto-Generate' and 'Auto-Posting' to fully automate the workflow. This allows you to choose the level of human oversight that fits your brand’s compliance and quality standards — from fully automated for trusted campaigns to fully manual for high-stakes launches.

Is there a free trial available for AGC Studio?

Yes. AGC Studio offers a free trial with 100 credits and full access to Base plan features — including the AI research system, content calendar, blog generator, and avatar creation — with no credit card required. This allows you to test all core capabilities, generate your first research report, create blog posts, and schedule content across platforms before committing to a paid plan.
