The brain is where your knowledge lives, powering accurate, on-brand responses across conversations. Sayy supports multiple input formats, allowing you to build a robust knowledge base that evolves with your business. #### 📲 Social Media Intelligence Plug in your social channels and let Sayy do the heavy lifting. Your AImployee can study your posts, captions, and even comments to understand your tone, offerings, and personality. Whether you are sharing tips on Instagram, videos on YouTube, or tweets with product updates, this feature turns your content into intelligence your AI can use instantly. This is one of the most powerful tools in Sayy, especially for creators. It allows your agent to speak with your voice and answer questions based on what you have already said across the internet. #### 📁 Upload Files and External Links You can also upload PDFs, documents, or even link to your company website. Sayy will extract the relevant information and make it available to your AImployee. Great for product catalogs, service guides, FAQs, or any reference material your audience might ask about. #### 📊 Dynamic Google Sheets Connect live Google Sheets for real-time data sync. Use this to power pricing, availability, inventory, or other operational information. The brain updates automatically, keeping your agent aligned with your backend in real time. #### ✍️ Manual Input and Q and A Builder Directly enter text and answer custom questions for proprietary knowledge, nuanced information, or any content not already published. You are in full control of how your agent responds to specific queries. The Sayy Free Plan includes a 2MB brain to help you get started. Higher-tier plans increase your brain capacity, enabling deeper knowledge integration and higher conversational accuracy. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://sayy-ai.gitbook.io/docs/train-the-brain.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
