Chrome Web Store: Cubbie for Claude
Response time
Usually within one working day (CET)

Getting started

Four steps, about a minute.

  1. 01

    Add to Chrome

    Install Cubbie for Claude from the Chrome Web Store. It works in Chrome, Edge, Brave and Arc.

  2. 02

    Open claude.ai

    Reload any open claude.ai tab. Cubbie replaces the left sidebar and a short tour shows you around.

  3. 03

    Make your folders

    Press + to add a folder, then drag chats in. Ctrl K jumps to any chat, folder or project.

  4. 04

    Unlock Pro (optional)

    Buy a plan, then paste the license key from your email into Settings, Cubbie Pro.

Troubleshooting

Most fixes take a few seconds.

Cubbie doesn't show up on claude.ai

Reload the claude.ai tab. If it still doesn't appear, check that Cubbie is turned on in chrome://extensions and has access to claude.ai. claude.ai sometimes changes its layout; if a Claude update breaks Cubbie, an update usually follows within a day or two.

My folders disappeared

Folders are kept in Chrome sync. Make sure you're signed in to the same Chrome profile, then reload claude.ai. Settings, Your data shows where your folders are stored.

My license key won't activate

Paste the whole key, starting with CUBBIE. A key works on 3 devices; if you've used them all, deactivate an old one in the customer portal and try again.

Where are my trashed chats?

Trash only hides chats. Open Trash on the left rail and drag a chat back to any folder to restore it. Cubbie never deletes anything from Claude.

Notifications don't appear

Notifications are a Pro feature. Turn them on in the theme menu, and allow Chrome to show notifications in your system settings (Windows: Settings, System, Notifications).
