e621tagger is a web-based tool that automatically generates relevant tags for furry artwork using the JTP-3 Hydra model by Project RedRocket. It provides a clean, responsive interface for copying tags in formats suitable for e621 and PostyBirb.
⚠️ Note: This repository contains the source code for the application. A live, fully functional instance is already available at the link above.
- Mobile-friendly – Works great on desktop and mobile screens with adjustable layout.
- PWA Ready – Install as a standalone app on mobile and desktop; works offline after first visit.
- Automatic Tagging – Upload an image and get up to 250 relevant e621 tags, complete with confidence scores.
- Two Copy Formats – Copy tags in e621 (space‑separated) or PostyBirb (comma‑separated) format with one click.
- Threshold Presets & Custom Values – Choose between Conservative, Standard, Liberal presets or set your own confidence thresholds for “All” and “Confident” tags.
- Manual Tag Overrides – Click any tag to force‑include (green) or exclude (red) it from copying, overriding the automatic thresholds.
- Category Grouping – Tags are grouped into categories like Copyright, Character, Species, Meta, General, Lore for easier browsing.
- Theme Support – Automatically follows your system theme (dark/light) with a manual override in settings.
- Drag & Drop / Paste – Drop an image anywhere on the page or paste from clipboard (Ctrl+V).
- Smooth Animations – Polished transitions for loading, showing/hiding results, and interacting with tags.
- Go to tagger.fenrir784.ru.
- Drag & drop an image onto the drop zone, Paste, or click to select a file (supports PNG, JPG, GIF, WebP, BMP, TIFF, max 20 MB).
- Wait a moment – the image is processed locally on the server (CPU‑based, usually under 2 seconds).
- Browse the generated tags, grouped by category.
- Confident tags (≥ 0.75 by default) are highlighted in purple.
- All tags (≥ 0.55 by default) are shown in muted blue.
- Tags below the threshold appear dimmed.
- Click any tag to manually include (green) or exclude (red) it from copying.
- Use the buttons to copy:
- Copy Confident Tags / Copy All Tags – copies all tags of that level in the currently selected format.
- Within each category, small C and A buttons copy only tags from that category.
- Adjust thresholds or default format via the ⚙️ Settings menu in the top‑left corner.
- Choose a preset or enter custom thresholds.
- Pick your preferred default format (e621 / PostyBirb) – this will be used for future uploads.
If you prefer to host your own instance, you can use the provided docker-compose.yml.
services:

container_name: e621tagger
ports:
- "5000:5000"
environment:
- TZ=Europe/Moscow # optional, adjust to your timezone
- SAVE_UPLOADS=true # set to false to disable file saving

restart: unless-stopped- Save the file as
docker-compose.yml. - Run
docker-compose up -d. - Access the app at
http://localhost:5000.
- The backend uses PyTorch and the JTP-3 Hydra model, a fine‑tuned image classifier trained on e621 data.
- When you upload an image, it is resized, converted to patches, and fed through the model.
- The model outputs confidence scores for over 7,500 possible tags; the adjustable amount of tags from top 50 to 250 are returned.
- All processing happens on the server; no data is sent to third parties.
- Backend: Python, Flask, PyTorch, Gunicorn
- Frontend: HTML, CSS, JavaScript
- Model: RedRocket/JTP-3 on Hugging Face
