1) Create mysql table:
CREATE TABLE `guilds` (
`guild_id` varchar(21) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
`workchannel` varchar(18) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
`lang` varchar(10) COLLATE utf8_unicode_ci NOT NULL DEFAULT 'eng'
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; )
2) Install node.js,
3) Edit config.json
( if you don't have trace.moe token set "trace_moe_token": false ),
4) Start bot: cmd -> node index.js
5) Add bot to your server,
6) Set work channel: +setchannel #channel_name
7) Send any anime image to work channel ;D
Bot sends image to https://trace.moe/ and resend reult to your work channel.
Possible reasons:
1. Your image is not an original anime screenshot.
2. The anime has not been analyzed yet.
3. Your image is flipped.
4. Your image is of bad quality.
Regarding 1. You may try to use SauceNAO and iqdb.org which is best for searching anime artwork.
Regarding 2. New animes currently airing would be analyzed around 24 hours after TV broadcast. Long-running animes / cartoons are excluded at this stage. See "What animes are indexed" at the bottom of this page.
As for 3. If you image comes from AMV / Anime Compilations, it's likely its flipped horizontally.
As for 4. The image search algorithm is designed for almost-exact match, not similar match. It analyze the color layout of the image. So, when your image is not a full un-cropped original 16:9 screenshot (i.e. cropped image), the search would likely fail.
Color is an important factor for the correct search, if heavy tints and filters are applied to the screenshot (i.e. grayscale, contrast, saturate, brightness, sepia), too much information are lost. In this case the search would also fail. The Edge Histogram can solve this issue by ignoring colors and only search edges. But I am running out of computing resource to support another image descriptor.
Image transform is also an important factor. If the image is not scaled without maintaining original aspect ratios (i.e. elongated, flipped, rotated), the search would also fail.
Text occupied too much of the image. Large texts on the image would interfere the original image. The system is not smart enough to ignore the text.
If you image has too little distinguish features (e.g. dark images or images with large plain blocks of plain colors), the search would also fail.
Searching with a real photo (of an anime) definitely won't work.

In case your screenshot has extra borders, please trim off the extra borders before you search.

Cropping the image would result a huge loss of information content.

This screenshot from AMV - Animegraphy 2015 flipped the original scene in the anime.
Not a good Screenshot
Original Screenshot
Tinted images are hard to search. Because the applied filter effects heavily distorted the information in the original screenshot. The color layout image descriptor can no longer find such images.
Sample Screenshot
Anime of this age are not indexed.
Sample Screenshot
You should try SauceNAO and https://iqdb.org/ to search anime / doujin artwork.
Sample Screenshot
Tom and Jerry is obviously not a Japanese Anime.
Sample Screenshot
Dark images are hard to distinguish using the colorlayout descriptor.
Sample Screenshot
Your image should be at least 320x180px to search effectively.

If the color distortion is acceptable, GIF is also OK.

The search image does not has to be taken from anime screencap directly. You can use drawings of some scenes as long as it is similar to the original one.
