The Promptr browser extension adds a sidepanel to ChatGPT, Claude, Gemini, and other AI tools. From there you can surface blocks as you type, browse your entire library, and save new blocks without leaving the AI tool.

​
Opening the sidepanel

Install the Promptr extension from the Chrome Web Store (or Firefox Add-ons), then navigate to any supported AI tool: Click the Promptr icon in your browser toolbar to open the sidepanel. The panel stays open as you work. You don’t need to reopen it for each conversation.

​
Enhance tab

The Enhance tab is the default view. It watches what you type in the AI tool’s input field and automatically surfaces matching blocks as suggestions.
The Enhance tab reads your input in real time. As soon as you start typing, Promptr searches your blocks and shows the closest matches. You don’t need to copy a block title exactly; matching finds relevant blocks even when the wording differs. The more you type, the more refined the suggestions become.
When suggestions appear, each block is shown as a card with its title, description, and tags. To insert a block:
  • Click the insert button on a card to use the block’s default AI behavior (attach, inline text, or full replacement).
  • Click the ··· menu on a card to choose a different behavior for this insertion only.
  • Click the copy icon to copy the block content to your clipboard without inserting it.
Click a card to open a full preview of the block content before deciding whether to insert it.

​
Filtering autocomplete results

While autocomplete is active, a compact filter bar appears at the top of the Enhance tab. You can narrow suggestions by:
  • Space: show blocks from specific spaces only
  • Tag: filter by one or more tags
  • Creator: in shared spaces, filter to a specific team member’s blocks
These filters persist between sessions (per tab). Use the Parse through panel in the idle state (shown when you haven’t started typing) to configure your default filters before you begin.

​
Browse tab

The Browse tab lets you manually navigate your entire block library, organized by space. This is useful when you know exactly which block you want but haven’t started typing yet.
1

Select a space

The Browse tab shows two collapsible sections: Shared spaces and Private spaces. Click any space card to open it.
2

Find your block

Inside a space, you’ll see all its blocks listed as cards. Use the Tags filter dropdown at the top to narrow by tag. You can also use the Properties dropdown to show or hide metadata columns on each card.
3

Insert or copy

Click the insert button on any block card to inject it into the AI tool’s input, or click the copy icon to copy the content to your clipboard. Tap a card to open a full preview first.
To return to the space list, click Back in the top-left of the block list view.

​
Quick Add

The Quick Add tab lets you save a new block directly from the extension, without switching to the Promptr web app. Fill in the following fields:
FieldRequired
TitleYes
SpaceYes (select the destination space from the picker)
TagsNo
DescriptionNo
AI behaviorNo (defaults to Attach to prompt)
ContentNo (can be added later in the web app)
Click Save to create the block. It’s immediately available in the Enhance and Browse tabs.
Quick Add creates a memory block in the current default type (Context). For a richer editing experience (including icons, descriptions, and full Markdown formatting), open the block in the Promptr web app after saving.
Your draft is automatically persisted between sessions, so you can start filling in a block and come back to it later without losing your work.

​
History

The extension keeps a local record of the blocks you’ve recently inserted. The history shows:
  • Which block was used
  • Which AI behavior was applied (attached, injected, or replaced)
  • Which AI tool the block was inserted into
  • When it was used
History is stored locally in your browser and helps you quickly re-insert blocks you’ve recently used.

​
Inserting a block: behavior options

Every block has a default AI behavior set when it was created. When you insert from the extension, you can use the default or override it on the fly:

Attach to prompt

Attaches the block as a file alongside your message. The AI reads it as supplementary context. Best for background information and reference material.

Insert at cursor

Injects the block content inline into the text input at your cursor position. Best for instructions and rules you want woven into your message.

Replace prompt

Replaces everything in the input field with the block content. Best for complete prompt templates.
To override the behavior for a single insertion, click ··· on the block card and select a different option before inserting.

​
Extension settings

Access settings by clicking the gear icon in the sidepanel header. From settings you can:
  • Switch workspace: if you belong to multiple workspaces, select which one the extension should pull blocks from.
  • Toggle theme: switch between light and dark mode independently of the web app.
