# RetentionRail > Know what to make. Know what to change. Before release. Audience intelligence before you publish, for creators and agencies. RetentionRail helps teams decide what to make, see where attention may drop, and know what to change before a video goes out. Video intelligence from 120M+ daily video observations maps content signatures to audience behavior, then prescribes what to change. Creative decisions happen early and audience outcomes arrive later; RetentionRail brings research, creative review and results into one workflow: Research → Screen → Edit. Audience responses are modeled estimates, not measurements of real viewers. Built for every content platform. YouTube, Instagram, TikTok and Facebook are live today. ## Product - [Home](https://retentionrail.com/): Product overview and the Research → Screen → Edit workflow - [Creator Intelligence](https://retentionrail.com/competitor-intelligence): Research creators, competitors, formats and references for your next idea - [AI Writer](https://retentionrail.com/ai-writer): Turn an idea and useful references into a script and storyboard - [AI Simulator](https://retentionrail.com/algorithm-simulator): Screen a script or rough cut for timestamped risks before release - [AI Assistant](https://retentionrail.com/ai-assistant): Ask questions about your connected performance and tracked creators - [MCP](https://retentionrail.com/mcp): Use RetentionRail inside Claude, ChatGPT and other MCP clients - [Connectors](https://retentionrail.com/connect): Supported platforms and data destinations - [Pricing](https://retentionrail.com/pricing): Plans and product access ## Who it is for - Creators deciding what to make next and what to change before they post - Agencies running research, creative review and results for many clients in one workflow - Editors and producers looking for the moment attention may drop and the specific next edit - AI agents that need governed creator intelligence through MCP ## Learn - [Methodology](https://retentionrail.com/methodology): How models are evaluated before they ship - [Blog](https://retentionrail.com/blog): Creator research and retention guides - [Help center](https://retentionrail.com/help): Product documentation - [FAQ](https://retentionrail.com/faq): Common product questions - [RSS feed](https://retentionrail.com/feed.xml): Latest articles - [Sitemap](https://retentionrail.com/sitemap.xml): Public crawlable pages ## Company - [About](https://retentionrail.com/about) - [Contact](https://retentionrail.com/contact) - [Privacy](https://retentionrail.com/privacy) - [Terms](https://retentionrail.com/terms) For a fuller product summary, see [llms-full.txt](https://retentionrail.com/llms-full.txt).
