As a mini program that requires downloading to use

do you mean you just want something that highlights posts that are in your favourites?

Look at the search cheatsheet user metatags: e621:cheatsheet#UserMetatags

A metatags for favorites exists

Beyond this I have no idea what you're looking for, feature requests need better explanations beyond a few vague words

It would help immensely if you were more descriptive of what you want, instead of giving single sentence descriptions such as this.
You can also try using the "Feature requests" template on topic #14916 to help us guide through what you are expecting and what pages would be affected.

If you want a third-party program to use alongside e621, it is very unlikely that the site developers would take on your request since it has nothing to do with the base site functionality.
Nonetheless, there are third-party scripts that people have made to be used alongside e621 (see e621:tools), though I do not think any of them specifically caters to what you are requesting here.

What I mean is Furaffinity Favorites

That is very unlikely to happen. It is not impossible to make a program that does just that, but rather it is going to be very time-consuming and technically-complex for a developer to create one just for you.

The closest thing you can get now is manually downloading the image you want to compare from FA and then searching via SauceNAO or Similar Image Search to see if it exists on e621.

Note than SauceNAO has a 100 search daily limit, and iqdb very often will not find posts unless the conditions are exactly right (and is also decently heavy on ratelimits)
MD5 matching is the only instant and practically unlimited method, but the amount of posts in the average person's favorites sourced to fa is likely much lower than not

Those are among the limitations of using the current method, which is why I said creating an external program to do something similar is not likely to happen.
Not to mention that MD5 matching only works if the image on FA exactly matches the one on e6, but more often than not, we would have a higher quality/different version that will cause a mismatch.

I agree, and feel like kubihazusaikou was explicitly shown how & why to properly format these things less than a week ago ...
I'd be interested in making a tool like this, but, as previously stated, I'm not starting that kind of project without details, and this is far from sufficient.

• What exactly are you looking for? If you want a local program, I'm gonna at least need to know what operating system you use.
• What is the goal? If it's to find FA posts to cross-post to e6, I'll remind you that you're expected to proactively get permission to post, and that some artists' work isn't on e6 because they don't want it to be, and you'll go from flirting with the ban hammer to kissing it if you cross that line too many times.
• A way to mitigate this is to auto-filter posts from artists on the Avoid Posting List/DNP; but again, that's why I need to know not just what you want, but why you want what you want.
• How technically minded are you? Can you handle a CLI, or do you need a GUI? Can you handle installing a script, or do you need a more robust solution?
• My todo list is long, so changing the title to the proper formatting might keep me from losing this thread when I have the time.

I hope having another concrete example as to why developers want requests presented a certain way was instructive.

it will spit out the URLs of all works that meet the conditions of the comparator,For example, stored in a folder in txt format

If I have sufficient knowledge of website APIs, I can use my poor programming skills to create a Python project in half an hour,The effect of this mini program is not difficult to implement,The general structure of this mini program is a web crawler that first extracts the content from my favorites,Then take a look at which works in E621 have their original addresses that can be extracted, and these contents overlap,Then store the non overlapping contents in a folder

Sorry for the vague request

tbh I'd just go one by one and use a tool like Fluffle (which has a browser extension that makes reverse image searching 2 clicks away) to determine if the post is already on e6 or not. That way you won't be hitting rate limits, you will find posts that are similar and not just exact matches, and you may even find links to the image on a site where it is higher quality, unaffected by FA's resolution limits. Checking if something is already posted is the fastest and easiest part of uploading, I don't really see why you'd want to spend more effort to automate it, and the tool still might be unreliable and/or too resource intensive. You will still be spending the vast majority of your time tagging regardless if you're a thorough tagger

I need the tutorial for this software now!!!!

Install the browser plugin from https://fluffle.xyz/tools/browser-extension/
Then you right click on an image and click "Reverse image search with Fluffle"
