A powerful, feature-rich GUI application for downloading content from **[Kemono.su](https://kemono.su)** (and its mirrors like kemono.party) and **[Coomer.party](https://coomer.party)** (and its mirrors like coomer.su).
Built with PyQt5, this tool is designed for users who want deep filtering capabilities, customizable folder structures, efficient downloads, and intelligent automation, all within a modern and user-friendly graphical interface.
*This v5.0.0 release marks a significant feature milestone. Future updates are expected to be less frequent, focusing on maintenance and minor refinements.*

## What's New in v5.0.0?
Version 5.0.0 is a major update, introducing comprehensive new features and refining existing ones for a more powerful and streamlined experience:
### β Favorite Mode (Artists & Posts)
- **Direct Downloads from Your Kemono.su Favorites:**
- Enable via the "**β Favorite Mode**" checkbox.
- The UI adapts: URL input is replaced, and action buttons change to "**πΌοΈ Favorite Artists**" and "**π Favorite Posts**".
- "**πͺ Use Cookie**" is automatically enabled and required.
- **Favorite Artists Dialog:** Fetches and lists your favorited artists. Select one or more to queue for download.
- **Favorite Posts Dialog:** Fetches and lists your favorited posts, grouped by artist. Includes search, selection, and known name highlighting in post titles.
- **Flexible Download Scopes for Favorites:**
- `Scope: Selected Location`: Downloads all selected favorites into the main "Download Location".
- `Scope: Artist Folders`: Creates a subfolder for each artist within the main "Download Location".
- Standard filters (character, skip words, file type) apply to content downloaded via Favorite Mode.
### π¨ Creator Selection Popup
- Click the "**π¨**" button next to the URL input to open the "Creator Selection" dialog.
- Loads creators from your `creators.json` file (expected in the app's directory).
- Search, select multiple creators, and their names are added to the URL input, comma-separated.
- Choose download scope (`Characters` or `Creators`) for items added via this popup, influencing folder structure.
### π― Advanced Character Filtering & `Known.txt` Integration
- **Enhanced Filter Syntax:**
- `Nami`: Simple character filter.
- `(Vivi, Ulti, Uta)`: Groups distinct characters into a shared folder for the session (e.g., "Vivi Ulti Uta"). Adds "Vivi", "Ulti", "Uta" as *separate* entries to `Known.txt` if new.
- `(Boa, Hancock)~`: Defines "Boa" and "Hancock" as aliases for the *same character/entity*. Creates a shared folder (e.g., "Boa Hancock"). Adds "Boa Hancock" as a *single group entry* to `Known.txt` if new, with "Boa" and "Hancock" as its aliases.
- **"Add to Filter" Button (‡οΈ):** Opens a dialog to select names from your `Known.txt` (with search) and add them to the "Filter by Character(s)" field. Grouped names from `Known.txt` are added with the `~` syntax.
- **New Name Confirmation:** When new, unrecognized names/groups are used in the filter, a dialog prompts to add them to `Known.txt` with appropriate formatting.
### π Manga/Comic Mode Enhancements
- **"Title+G.Num" Filename Style:** (Post Title + Global Numbering) All files across posts get the post title prefix + a global sequential number (e.g., `Chapter 1_001.jpg`, `Chapter 2_003.jpg`).
- **Optional Filename Prefix:** For "Original File" and "Date Based" manga styles, an input field appears to add a custom prefix to filenames.
### πΌοΈ Enhanced Image & Content Handling
- **"Scan Content for Images":** A checkbox to scan post HTML for `![]()
` tags and direct image links, resolving relative paths. Crucial for images embedded in descriptions but not in API attachments.
- When "Download Thumbnails Only" is active, "Scan Content for Images" is auto-enabled, and *only* content-scanned images are downloaded.
- **"π§ Only Audio" Filter Mode:** Dedicated mode to download only common audio formats (MP3, WAV, FLAC, etc.).
- **"π¦ Only Archives" Filter Mode:** Exclusively downloads `.zip` and `.rar` files.
### βοΈ UI & Workflow Improvements
- **Cookie Management:**
- Directly paste cookie strings.
- Browse and load `cookies.txt` files.
- Automatic fallback to `cookies.txt` in the app directory.
- **Multi-part Download Toggle:** Button in the log area to easily switch multi-segment downloads ON/OFF for large files.
- **Log View Toggle (ποΈ / π):** Switch between the detailed "Progress Log" and the "Missed Character Log" (which now shows intelligently extracted key terms from skipped titles).
- **Retry Failed Downloads:** Prompts at the end of a session to retry files that failed with recoverable errors (e.g., IncompleteRead).
- **Persistent UI Defaults:** Key filter scopes ("Skip with Words" -> Posts, "Filter by Character(s)" -> Title) now reset to defaults on launch for consistency.
- **Refined Onboarding Tour & Help Guide:** Updated guides accessible via the "β" button.

### Filtering & Content Selection
- **π― Filter by Character(s):**
- Enter character names, comma-separated.
- **Syntax Examples:**

- **Filter: [Type] Button (Scope):** Cycles how this filter applies:
- `Filter: Files`: Checks individual filenames. Only matching files from a post are downloaded.
- `Filter: Title`: Checks post titles. All files from a matching post are downloaded.
- `Filter: Both`: Checks post title first. If no match, then checks filenames.
- `Filter: Comments (Beta)`: Checks filenames first. If no file match, then checks post comments. (Uses more API requests).
- **π« Skip with Words:**
- Enter words (comma-separated) to skip content (e.g., `WIP, sketch`).
- **Scope: [Type] Button:** Cycles how skipping applies:
- `Scope: Files`: Skips individual files by name.
- `Scope: Posts`: Skips entire posts by title.
- `Scope: Both`: Post title first, then filenames.
- **βοΈ Remove Words from name:**
- Enter words (comma-separated) to remove from downloaded filenames (e.g., `patreon, [HD]`).
- **Filter Files (Radio Buttons):**
- `All`: All file types.
- `Images/GIFs`: Common image formats.

- `π Only Links`: Extracts and displays external links from post descriptions. Disables download options.
- **Skip .zip / Skip .rar Checkboxes:** Avoid downloading these archive types (disabled if "π¦ Only Archives" is active).
### Download Customization
- **Download Thumbnails Only:** Downloads small API preview images.
- If "Scan Content for Images" is also active, *only* images found by content scan are downloaded (API thumbnails ignored).
- **Scan Content for Images:** Scans post HTML for `![]()
` tags and direct image links, resolving relative paths.
- **Compress to WebP:** If Pillow is installed, converts images > 1.5MB to WebP if significantly smaller.
- **ποΈ Custom Folder Name (Single Post Only):**
- Visible if downloading a single post URL AND "Separate Folders by Name/Title" is enabled.

- `Name: Date Based`: Files named sequentially (e.g., `001.jpg`) by post date. Optional prefix input appears. Disables post-level multithreading.
### Folder Organization
- **Separate Folders by Name/Title:** Creates subfolders based on "Filter by Character(s)" or post titles. Uses `Known.txt` as a fallback.
- **Subfolder per Post:** If "Separate Folders" is on, creates an additional subfolder for each post.

- *Creator Feeds:* Number of posts to process simultaneously.
- *Single Post URLs:* Number of files to download concurrently.
- **Multi-part Download Toggle Button (in log area):**
- `Multi-part: ON`: Enables multi-segment downloads for large files. Can speed up large file downloads but may increase UI choppiness or log spam with many small files.

- Disabled if "π Only Links" or "π¦ Only Archives" mode is active.
### Logging & Monitoring

## Key Files
- **`Known.txt`:** (Located in the application's directory)
- Stores your list of known shows, characters, or series titles for automatic folder organization.
- **Format:** Each line is an entry.
- Simple: `My Awesome Series`
- Grouped (single `Known.txt` entry, shared folder): `(Boa, Hancock)` - creates folder "Boa Hancock", aliases "Boa", "Hancock".
- Used as a fallback for folder naming if "Separate Folders" is on and no active filter matches.
- **`creators.json`:** (Expected in the application's directory)
- Used by the "π¨ Creator Selection Popup".
- A JSON file containing a list of creator objects. Expected structure: `[ [ {creator1_data}, {creator2_data}, ... ] ]` or a flat list `[ {creator1_data}, ... ]`.
- Each creator object should ideally have `name`, `service`, `id`, and optionally `favorited` (integer count for sorting in popup).
- *Example entry in the inner list:* `{"id": "12345", "name": "ArtistName", "service": "patreon", "favorited": 10}`
- **`cookies.txt` (Optional):**
- If "Use Cookie" is enabled and no direct string/file is provided, the app looks for this in its directory.
- Must be in Netscape cookie file format.
- **Application Settings:** UI preferences (like manga style, multipart preference) are saved by Qt's `QSettings` (location varies by OS). Cookie details and some filter scopes are session-based.

## Installation
### Requirements
- Python 3.6 or higher
- pip (Python package installer)
### Install Dependencies
Open your terminal or command prompt and run:
```bash
pip install PyQt5 requests Pillow
```
```bash

### 2. Optional Setup
- Place your `cookies.txt` in the root directory (if using cookies).
- Prepare your `Known.txt` and `creators.json` in the same directory for advanced filtering and selection features.
---
## Tips & Best Practices
- For best results, use **Favorite Mode** if you're a logged-in user with bookmarked artists/posts.
- Use **Filter by Character(s)** and keep your `Known.txt` updated to reduce clutter and organize downloads.
- Use the **multi-part toggle** for large video/audio files but disable it when downloading large batches of small images to reduce overhead.
- Adjust **thread count** based on your internet speed and CPU; too many threads can result in API throttling.
---
## Troubleshooting
- **Downloads not starting?**
- Ensure the download location is set.
- Check your filters aren't too strict.
- If in Favorite Mode, make sure cookie is set and valid.
- **Missing characters/folders?**
- Review the Missed Character Log.
- Use the "Scan Content for Images" option if image links are embedded in descriptions.
- **App crashes or logs errors?**
- Check the console/log area for stack traces.
- Run from terminal to capture more error output.
- Ensure `Known.txt` and `creators.json` are valid.
