  Why? I want to check the url is submitted or not by HN in chrome extension, but don't want to call HN Search API (https://hn.algolia.com) every time for security issue.

  Result? 10 year links in HN count is about 2143436, total bloom filter size 2143436 * 2B, file size ~ 5M. Find building status in https://hackernewsfilter.com/status/ . The bloom filter factors can be found in https://hackernewsfilter.com/faq/#check .

  Product? The chrome extension based on these data can be find in https://hackernewsfilter.com/ , after install, you can check if an url is submitted or not when every time you open a link.

  Enjoy!

  This seems like a great idea!

  I usually try to avoid commenting on grammar or spelling too much, but it seems like you're a non-native speaker of English, and it's a bit tricky to understand some of what you're intending.

  Here's some suggestions that might make the site's purpose a bit clearer (just suggestions!)

  On the main page:

  "Easily find out if the web page you're reading has been discussed on Hacker News, with no API calls"

  On /check:

  "Automatically find HN discussions when web-browsing, securely"

  and

  "Borrow HN community intelligence on every page".

  On /status:

  "For details about how to use the bloom filter file, check here"

  On /feedback:

  "I found an issue"

  I'm not sure what you mean by "I want to format the url", so I'm not sure what to suggest there.

  If you like, I can follow up or file an issue, with suggested rewrites for /faq. There's a lot more there than can fit in a single post.

  huan9huan - in case you're interested, you can usually make a Firefox extension and a Chrome extension from the same codebase. Check out https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Po...

  Let me know how it goes - I'm happy to (try to) answer any questions you have about the process!

  This is cool. I like that websites I visit won't get recorded by someone else however this needs to be open source. I no longer install Chrome plugins that are not open source or coming from very well known public companies.

  Awesome work!

  From your FAQ:

  Q: Cost and make money?

  Not very sure how to make money

  Not sure you'll make money from this service but with this talent it seems you can easily segue into other services.

  For example, HN doesn't have any usable way to save and retrieve threads that you find most interesting/informative/funny. You've solved half of that already.

  Solve the other half and you've basically built a bookmarking service. Some good UI/UX and clever marketing positioning and there's a product probably worth paying for.

  Best of luck.

  On the pinboard.in/popular page, it would be useful to have an icon linking to the HN discussion. In fact, lets also have one to the Reddit discussion.

  If someone has some time, this could be a useful extension.

  Although HN becomes front page of internet for me nowadays, it is still good idea! for submission part, it saves round trip to NH if article has been submitted

  Congrats, OP!

  Thank you for making this. I can't wait this coming on Firefox.

  For DDG users !hn has a similar functionality, but it does redirect you the HN Search API.

  A very useful HN plugin！
