# Browser Extension

> Install the Promptr sidepanel and use your memory blocks directly inside ChatGPT, Claude, and Gemini.

The Promptr browser extension adds a sidepanel to your AI tools that gives you instant access to your entire memory block library without leaving the chat. You can let it surface blocks automatically as you type, or browse and search your spaces manually.

## Supported browsers

| Browser | Support     |
| ------- | ----------- |
| Chrome  | Supported   |
| Firefox | Supported   |
| Edge    | Coming soon |
| Opera   | Coming soon |

## Supported AI sites

The extension activates on these sites automatically:

* **ChatGPT:** chatgpt.com and chat.openai.com
* **Claude:** claude.ai
* **Gemini:** gemini.google.com

It also works on the Promptr web app ([app.promptr.ai](https://app.promptr.ai)) so the extension can detect that you're signed in.

## Installation

<Steps>
  <Step title="Install the extension">
    <Tabs>
      <Tab title="Chrome">
        Visit the Promptr listing in the [Chrome Web Store](https://chromewebstore.google.com/detail/dflghcilkkpilpinokddfmoolddhkhlf) and click **Add to Chrome**.

        Once installed, the Promptr icon appears in your browser toolbar. Pin it for easy access by clicking the puzzle-piece icon in your toolbar and pinning Promptr.
      </Tab>

      <Tab title="Firefox">
        Visit the Promptr listing on [Firefox Add-ons](https://addons.mozilla.org/en-US/firefox/addon/promptr-for-ai/) and click **Add to Firefox**.

        After installing, the Promptr icon appears in your Firefox toolbar.
      </Tab>
    </Tabs>

    <Note>
      Support for Edge and Opera is coming soon.
    </Note>
  </Step>

  <Step title="Sign in">
    Click the Promptr icon in your toolbar. The extension opens a login screen.

    Sign in with **Google** or your **email address**, the same credentials you use at [app.promptr.ai](https://app.promptr.ai).

    <Note>
      Your blocks sync in real time through your account. You need to sign in for the extension to access your library. If you want to explore first without an account, click **Try as guest**. Your guest blocks will migrate to your account when you sign up later.
    </Note>

    If you have more than one workspace, you'll be prompted to pick which one to open. You can switch workspaces from the sidepanel at any time.
  </Step>

  <Step title="Open the sidepanel">
    Navigate to ChatGPT, Claude, or Gemini. To open the Promptr sidepanel:

    * **Chrome:** Click the Promptr icon in your toolbar, or right-click the page and select **Open Promptr sidepanel**
    * **Firefox:** Click the Promptr icon in your toolbar

    The sidepanel docks to the side of your browser window alongside the AI tool's chat interface.
  </Step>
</Steps>

## Guest Mode

Don't have an account yet? You can try Promptr directly from the extension without signing up. Click **Try as guest** on the login screen to get started right away.

In guest mode, your memory blocks are stored locally in your browser — nothing syncs to the cloud. You can still create blocks, browse your spaces, and insert content into ChatGPT, Claude, or Gemini just like a full account.

The main limitation is search. Guest mode uses keyword matching to surface suggestions in the Enhance tab, so suggestions are based on exact or partial word overlap with what you're typing. Full semantic search — which finds relevant blocks based on meaning, even when the wording doesn't match exactly — requires a Promptr account.

Keyword matching is still a great way to experience the core idea: having the right context ready the moment you need it, without leaving the chat.

<Tip>
  When you're ready to sign up, your guest blocks migrate to your new account automatically — nothing gets left behind.
</Tip>

## Sidepanel views

Once the sidepanel is open, you can switch between four views using the navigation icons.

### Enhance

The default view. Promptr watches what you type in the AI tool's chat input and automatically surfaces matching blocks from your library. Suggestions appear in real time as you type a new message.

* Click a block to insert its content into the chat input
* Filter suggestions by space, tag, or creator using the filter bar
* Click **Reload** to re-run the search with your current input

<Info>
  Enhance only triggers on **new chats**, not existing conversations. This prevents suggestions from appearing mid-conversation when they're less relevant.
</Info>

### Browse

Manual exploration of your spaces and blocks. Use Browse when you know what you're looking for or want to review your library.

* Navigate into any space to see its blocks
* Filter by tag or creator
* Click a block to preview it, then insert it into the chat

### History

Shows blocks you've recently used across all your AI tools. Jump back to something you inserted earlier without having to search for it again.

### Quick Add

Save a new block directly from the extension without opening the web app. Useful for capturing something mid-conversation. Paste in the content, give it a title, choose a space, and save.

## Inserting blocks

When you click a block, Promptr inserts its content into the active chat input. The exact behavior depends on the block's **AI behavior** setting:

| Behavior    | What happens                                                                                                 |
| ----------- | ------------------------------------------------------------------------------------------------------------ |
| **Attach**  | Content is attached alongside your message as a separate context block. Recommended default for most blocks. |
| **Inject**  | Content is inserted directly into the conversation as inline text. Best for instructions and rules.          |
| **Replace** | Content replaces everything currently in the input. Best for complete prompt templates.                      |

## Workspace switcher

Your current workspace is shown in the sidepanel navigation. Click on it to switch to a different workspace or, if you're on a team workspace, to invite teammates.

<Note>
  If a team workspace is paused due to a billing issue, the extension will show a notice and prompt you to resolve it in the web app at [app.promptr.ai](https://app.promptr.ai).
