Write rules for how Erlin generates product pages, collections, blog articles, and compliance content. Erlin reads these guidelines every time it creates content for you and applies them to the output. ## What Memory is for Memory is where you tell Erlin how to write for your brand beyond tone and voice. If every product page should include a specific disclaimer, put it in the **Product** tab. If blog articles should always mention a core value proposition, put that in the **Blog** tab. If there are legal or regulatory statements Erlin must include, put those in the **Compliance** tab. Erlin treats Memory as instructions it must follow during content generation. The more specific your guidelines, the more consistent the generated content. ## The four tabs Open **Brand > Memory** to see four tabs, each governing a different content type: | Tab | What it controls | | -------------- | ---------------------------------------------------------------------------- | | **Product** | Guidelines for how Erlin writes product page content | | **Collection** | Guidelines for how Erlin writes collection and category page content | | **Blog** | Guidelines for how Erlin writes blog articles and long-form content | | **Compliance** | Legal, regulatory, or brand rules Erlin must follow in all generated content | Each tab has its own rich text editor. Guidelines in one tab do not affect the others. Erlin reads the relevant tab based on what type of content it is generating. ## Writing guidelines manually Open **Brand > Memory**, pick a tab, and write your guidelines in the editor. The editor supports rich text: headings, lists, bold, and links. Write in plain language as if instructing a human writer. Examples of useful guidelines: * "Always include the product's key differentiator in the first paragraph" * "End every product page with a call to action linking to /demo" * "Never mention competitor names directly in blog content" * "Include GDPR compliance language in any page that mentions data collection" Click **Save** when finished. Erlin applies the saved guidelines the next time it generates that content type. ## Using AI Assist to generate guidelines If you prefer a starting point over a blank page, click **AI Assist** on any tab. Erlin analyzes your website to generate guidelines for that content type. It looks at: * Sample pages from your sitemap matching that content type * Your brand tone and voice settings * Your products and services information Erlin produces a draft set of guidelines based on how your existing content is written. Review the output, edit anything that needs changing, and save. You can run AI Assist multiple times to regenerate, and you can edit the result freely afterward. ## How Erlin uses Memory **During content generation.** When you create an article, product page, or collection in Erlin, it loads the matching Memory tab and follows those guidelines. Product generation reads the **Product** tab. Article generation reads the **Blog** tab. Collection generation reads the **Collection** tab. **Compliance** rules apply across all content types. ## Related The writing style Erlin uses alongside Memory guidelines.
