    Hey, I want to show you my demo AI-powered app that helps summarise someone's recent tweets to help you decide whether to follow them. It'll give you an idea of the tone and languages they use too, If you don't want to spend time scrolling through Tweets, let AI tell you what someone's been Tweeting about recently! Built with Haystack: https://github.com/deepset-ai/haystack It uses text-davinci-003 from OpenAI (for now) with a custom Haystack PromptTemplate. You can check out the source code here too: https://github.com/TuanaCelik/should-i-follow

    We wanted a way to share what we had learned online (first expressed by what we had shared on twitter). So we built this. http://knowitapp.com/paulg http://knowitapp.com/foundersatwork http://knowitapp.com/paultoo http://knowitapp.com/garrytan http://knowitapp.com/gralston http://knowitapp.com/harjeet (Bonus: you can see your similarity if you login - and no we won't tweet from your account) What do you guys and gals think?

    Hi HN! I built this tool, because Large Language Models are hallucinating their asses off and I wanted to test just how bad it is with a topic I know best - myself. I'm sure there are other egos out there who google themselves and essentially this is the new googling yourself. It's early beta, so lots of room for improvement of course.

    I made an AI version of thread/twitter, where you are the only human user and everyone else is an AI friend. It’s called Melonn(melonn.xyz), a human-free AI social space. The initial goal is to provide people with a safespace where they can say anything they want, and get feedbacks/responses to their thoughts-be it a useful insight or kind words of sympathy. If you ever feel lonely, lost, bored or sad just come here and express how you feel without having to care about what others would think. We are actively looking for feedbacks/opinions to improve the service! Thank you.

    Hey everyone, Common advice for inexperienced hackers suggests "scratching an itch." Like many others here, I spent too much time on HN, Google Reader and Twitter searching for interesting stuff, so I decided to write an app that brings interesting links to you with no other distractions. HighFive uses Twitter and bit.ly's APIs to find interesting links in your timeline. When you log in, you'll see a group of five links with voting arrows. No HN comments or RSS feeds with hundreds of links--just a few interesting articles that you can read, then get back to work. HighFive was built using…

    Excited to share something I've been building recently called ReplyGuy. I made it to solve a personal pain with a SaaS product I built, which was that we were always monitoring Reddit and Twitter to see if anyone had mentioned keywords indicating they were looking for us. Before, we had to go manually respond to posts, often missing good mention opportunities. Would love for HN folks to try it and let me know what you think!

    Hi HN, I over-thought one too many “lol sounds fun” texts and decided to teach a model to be my wingman instead. The result is Crush Check AI —export an iMessage / WhatsApp / Instagram thread and get a chat report with: * crush score (0-100) based on response latency, reciprocity, sentiment shifts. * red flags like like breadcrumbing / love-bombing * chat timeline. You can also ask questions about your conversation. Why post here I’d love feedback on: * whether this is something people need. * how was the user experience. * what features would you like to see. Thanks in…
