A memory block (or simply a memory) is a named, reusable piece of AI content. You write it once, store it in a Space, and inject it into ChatGPT, Claude, or Gemini via the Promptr browser extension, without retyping or copy-pasting brand context, guidelines, or prompts every time. Every memory block has a title, content, and an AI behavior mode that controls how the extension delivers it to the AI.

​
Block types

Promptr’s data model supports multiple block types. Currently, all memory blocks use the Context type. Additional types (Instruction and Prompt) are coming soon as part of upcoming AI-assisted creation features.
Context blocks carry background information the AI needs to understand your situation: brand voice, audience details, campaign briefs, product facts, or any reference material a marketing team needs to stay consistent.Use a Context block when you want to give the AI relevant background without making it the focus of your message.Examples:
  • Brand voice and tone guidelines
  • Target audience personas
  • Client background and product details
  • Campaign briefs or project context
Context blocks default to the Attach AI behavior, which sends the block as a separate context item alongside your message.

​
Block properties

Each memory block stores the following fields:
PropertyDescription
TitleThe display name you use to find and identify the block.
ContentThe actual text delivered to the AI. Supports Markdown.
AI behaviorHow the extension delivers the block: attach, inject, or replace.
DescriptionAn optional short summary shown in the block browser to help you and your team understand what the block does.
IconAn optional visual identifier. Choose an emoji, a flat icon from the built-in library, or upload a custom image.
TagsWorkspace-level labels for filtering and organizing blocks.

​
AI behavior modes

The AI behavior setting controls exactly how the browser extension sends your memory block to the AI tool. You can override the default for any block.

Attach

Attached as a separate context block alongside your message. This is the recommended default for most blocks, keeping your actual message clean while still providing the AI with the block’s content.

Inject

Injected directly into the system prompt or conversation. Best for instructions and rules that need to be woven into the prompt flow rather than presented as a separate attachment.

Replace

Replaces your entire input with the block’s content. Best for complete, self-contained prompt templates that require no additional message from you.
If you’re unsure which behavior to use, leave it set to Attach. It works well for the majority of blocks and keeps the interaction predictable.

​
How blocks are organized

Memory blocks live inside Spaces. Every block belongs to exactly one Space, and you can move a block to a different Space at any time. Spaces let you group blocks by client, project, or team, in any structure that fits your workflow. See Spaces for details on how to organize your memory blocks.

​
Usage tracking

Promptr tracks how you use your memory blocks so the most relevant content is always close at hand:
  • Recently used: the extension surfaces blocks you’ve used recently so you can re-apply them quickly.
  • Usage count: each block records how many times it has been used, giving you a signal for which blocks are delivering real value.
Both metrics are tracked per user, so your recently used list is personal to you even in a shared team Space.
