Chub Ripper

Important

This plugin was made using AI IDEs like cursor and copilot in visual studio! Most I have done is just test to make sure everything is operational. Thank claude sonnet & opus 4.6 for the code <3

A python script with a gui that downloads your Chub.ai character cards, lorebooks, presets, personas, and chat history to your local machine. Runs on Windows, macOS, and Linux.

---

Requirements

• Python 3.11, 3.12, or 3.13 — python.org
  • On Windows, check "Add Python to PATH" during install

All Python package dependencies are installed automatically by the launch script.

Package	Purpose
customtkinter	GUI framework
Pillow	Image processing for card thumbnails
playwright	Headless browser used to intercept API calls
requests	HTTP downloads

---

Quick Start

Windows — double-click run.bat

macOS / Linux — open a terminal in the folder and run:

chmod +x run.sh
./run.sh

Both scripts will automatically:

• Install all required Python packages via pip
• Install the Playwright Chromium browser (first run only)
• Launch the app

---

Manual Setup (optional)

If you prefer to install dependencies yourself:

pip install -r requirements.txt
playwright install chromium
python chub_ripper.py

Getting Your API Key

1. Open chub.ai in your browser and log in
2. Open DevTools (F12)
3. Go to the Network tab
4. Click any page on Chub.ai to trigger a network request
5. Look for a request to ro.chub.ai
6. Click it, go to Request Headers, and copy the value of Ch-Api-Key

Paste this key into the Ch-Api-Key field in the app. It is remembered between sessions so you only need to do this once.

Note: On Windows the key is encrypted at rest using Windows DPAPI. On macOS and Linux it is saved as plain text in a .chub_token file next to the script, so avoid storing it in a publicly shared folder.

---

Usage

1. Launch the app via run.bat
2. Paste your Ch-Api-Key into the field at the top (click Show to verify)
3. Check the content types you want to fetch:
   • Cards — character card files
   • Lorebooks — lorebook files
   • Presets — saved presets
   • Personas — persona files
   • Chats — chat session history
4. Choose your preferred output formats:
   • Card fmt: PNG (card embedded in image) or JSON (raw data)
   • Chat fmt: JSONL, JSON, or TXT
5. Click Fetch — the app fetches your library and displays tiles with thumbnails
6. Use the ✓ All / ✗ None buttons per tab to select or deselect items
7. Click ⬇ Download All to save everything selected

To cancel a fetch or download in progress, click the button again (it becomes a cancel button).

Note: The app may lag or feel unresponsive while loading a large library (hundreds of cards, presets, personas, etc.). This is normal — thumbnails and tile data are being fetched in the background. Give it a moment and it will catch up.

Output Folders

All files are saved next to chub_ripper.py:

Chub Ripper/
├── Cards/          ← character card files (.png or .json)
├── Lorebooks/      ← lorebook files
├── Presets/        ← preset files
├── Personas/       ← persona files
├── Chats/          ← chat logs, organized by character
│   └── CharacterName_ID/
│       └── session-name.jsonl (or .json / .txt)
└── debug.log       ← log of the last session (useful for troubleshooting)

Items that already exist locally are skipped automatically (shown as "Already saved").

Network connections

This app only contacts Chub.ai servers. Every URL it fetches is shown in the status bar while it runs. The full list of domains:

Domain	Purpose
chub.ai	Headless browser navigates here to load your cards/chats pages
ro.chub.ai	Chub's read-only API — verifies your key, searches for cards/lorebooks/presets
gateway.chub.ai	Chub's gateway API — fetches personas and chat history
avatars.charhub.io	Chub's CDN — downloads card and character avatar images

No data is sent to any third party. The headless Chromium browser launched during fetch uses a fresh isolated session (no cookies, no stored credentials) so it has no access to any browser accounts.

---

Troubleshooting

"Could not find Python" — Install Python 3.11+ and make sure to tick "Add Python to PATH" during setup.

"API key rejected (401/403)" — Your key has expired or is wrong. Re-copy Ch-Api-Key from DevTools.

Fetch returns 0 items — Make sure you are logged into Chub.ai in your browser before copying the key, and that the key is not prefixed with Bearer (the app strips this automatically, but double-check).

App crashes or items fail — Check debug.log in the app folder for details.
