Ask HN: Getting an email when a HN post mentions a keyword?

I have created a RSS Crawler and HTML represent it. On a update there were a need for what you asking for / exclusive_keywords.keywords text, will appear. The existence of this is to filter the important feed articles / You can setup this to /heroku/ enter the /hnrss/ URL provided by @jugurtha and you are ready to go. ref - https://github.com/pipiscrew/RSS-Aggregator <> the quick 'hacky' way, is again to use the /hnrss/ URL provided by @jugurtha and paste the URL to https://simplepie.org/demo/ then press /read/ :) <> or the easiest (never tried) https://rssby.email/ again to use the /hnrss/ URL provided by @jugurtha

I'm working on a tool like that, feel free to check out https://syften.com.

I would need such an app.

Also, would be nice if the app would understand lexical fields. Eg, sending posts about Java, even when "java" is not explicitly mentioned.

If the app doesn't exist and is of interest to others, I'd love contribute to developing it.
