    I've been working on and off on a Chrome Extension for Hacker News, the extension focusses on improved usability rather than design. I can almost guarantee that after a day you won't want to go back to regular Hacker News. Give it a try, features include: - Improved readability - Quick inline replies from comments page - Quick profiles with social network info when hovering over usernames - Filtering of stories based on terms and phrases / domain or user - Endless scrolling - Collapsible comment threads - Social sharing for Twitter, Facebook, Google+, Buffer Forks, improvements and comments…

    Type /ai + your prompt in any textbox and the ChatGPT will do the job I've made this project so I could learn how to create Chrome extensions. I know there are already a lot of alternatives for it, but this was a learning project and I would love some feedback on the code. ( I was unable to make it work on sites that use the React Lexical editor, i.e Reddit, Facebook, etc :( )

    Hello! I built this to solve a personal problem of where I didn't want to wade down large chains of HackerNews comment threads in order to get the key takeaways from the discussions. I built this Chrome extension, which supports both OpenAI and Ollama(local LLMs) to summarize comments and display the summary within Chrome's sidepanel. It's open source as you can see from the link, feedback appreciated!

    Today I designed a method to prevent users from jailbreaking ChatGPT (for instance, users have generated instructions to produce weapons or illegal drugs, commit a burglary, kill oneself, take over the world as an evil superintelligence, or create a virtual machine which they then can use). The OpenAI team appears to be countering these primarily using prompt engineering or fine-tuning on the ChatGPT model. The idea is to use a second and fully separate, fine-tuned LLM to evaluate prompts before sending them to ChatGPT. You can test this by inserting your successful ChatGPT jailbreaks. Break…

    Hi HN, I'm one of the creators of Nanobrowser, an open-source Chrome extension that lets you automate web tasks using AI agents. We were inspired by the potential of tools like OpenAI's Operator, but we wanted something that was: -Open-Source:You can see the code, modify it, and contribute to the project. -Browser-Based:No complex setups or server deployments. It runs directly in your browser. -Customizable:You can tailor the agent's behavior to your specific needs. -BYO LLM:Bring your own large language model API key (OpenAI, Anthropic,or even local models), No vendor lock-in. -Privacy…

    Link: http://www.gethackertools.com Hey guys, I love Hacker News like all of you do, I spend a good portion of my time reading interesting content and the best, your replies... My only gripe is extra functionality that I know PG doesn't want to have to deal with... So I came up with this idea to make a super extension that does all the things I want, plus merges all the other cool HN extensions into one... Only problem? I don't have much time to put into it, so I figured why not open source it, and allow anybody in the community to fork it, improve it, add functionality, whatever they want,…

    Hi guys, For my startup at www.mithrin.ai which is about create AI Chatbot Agents for websites, I wanted to create some free tools to attract traffic to the site and decided to create specialized chatbots powered by LLMs, similar to OpenAI's Custom GPTs. I realized that by using gpt-4o-mini, I could create quite powerful alternatives to GPTs that are free to the public for a very small cost (given how cheap the model api cost is). I've employed some throttling to prevent abuse and to avoid being charged too much. Then I integrated this with my main service and allowed users to use the…

    Hello HN! A few days ago I saw a comment on reddit which proposed a service that allowed the user to spam a website's server logs with messages objecting to the presence of various anti-features like popups, noisy ads, and autoplaying content. The idea tickled my fancy, so I've put together a Chrome extension which detects if a page is using Google Analytics, and if so it injects a small script which sends bunk utm (urchin tracking module) data to the GA backend. It sets the traffic source to "DO NOT WANT!", and the campaign name to various things like "I do NOT want noisy ads!" Here's the…

    Hey HN! I love the OpenAI Playground UI but I don't love the Auth0 implementation causing me to waste precious minutes entering 2FA codes... so I spent a week cloning the basic features of the OpenAI Playground UI, all in a single HTML file. You can try it on github pages[0] or run it locally in your browser. Just paste your API key and hit start to begin using it. You can also add your key to the URI fragment[1] and bookmark it to start immediately. [0] https://minwidth0px.github.io/gpt-playground [1] like https://minwidth0px.github.io/gpt-playground#API_KEY

    I'm building an AI platform, FlowChai and found a neat use case for it today that I thought would be useful to HN readers. I use GPT4 heavily for writing / editing code, but a major downside is that it doesn't know about new projects. I made the connection today that I could upload the zip file of a Github repo to FlowChai and then write prompts just like with ChatGPT with code questions. While the original intent for this platform is more around natural language, it's neat how this works so well. It's powered underneath by pgvector and OpenAI embeddings.

    I'm so tired of all that crappy AI content that is published every day. It's becoming way harder to find genuine creators on the internet because they are being overshadowed with massive amount of AI-driven material. I think I'm not the only one who thinks like that and that is why I've published "Is Generated" it's a community based Chrome Extensions where users can report, vote and block the content they suspect is AI-generated. Together, we can take back control and make the internet a better place for authentic creators!

It uses Javascript (obviously), python (Flask) and Redis. I would love to hear any comments or suggestions.Thanks.

    I'm a network engineer that likes to think about the future of the internet and this is what I've built over many nights and weekends. One reputation graph over IPs, ASNs, domains, and entities, exposed as a JSON API. Try it: curl https://api.tunnelmind.ai/v1/check/1.1.1.1 Every answer is a signed receipt with an attestation tier so you can see what was produced and how your agents can use it. The protocol is opensource. Try it out let me know what you think and yes I am still working on the radar section of the site. Also What would make this useful for you?

    I built this using semantic search and the ChatGPT API, which was just released the other day. What makes it special is it not only understands the code you're debugging, but also pulls in additional context like relevant documentation to help answer your questions and suggest code changes. Ultimately, my goal is to take the hassle out of pasting error messages into Google, finding a vaguely related StackOverflow post, and manually integrating the solution into your code.

    Whether it is a designer ultra-tweeting about some conference she is at or a venture capitalist intensely describing his pursuit of the always-elusive "inbox zero", sometimes you just want to mute someone you follow on Twitter. This extensions allows you to do just that. You can easily put accounts that you follow in the penalty box, where they will be silenced and feel shame. When you have deemed their sins absolved, you can let them out, free to fill your Twitter stream again. Download: http://bit.ly/u1giXH Read About: http://bit.ly/tdqX6y Source: http://bit.ly/tmxvf1

You can find the repo here https://github.com/Legit-Control/monorepo and the website here https://legitcontrol.com Over the last years, we worked on multiple developer tools and AI driven products. As soon as we started letting agents modify real files and business critical data, one problem kept showing up. We could not reliably answer what changed, why it changed, or how to safely undo it. Today, most AI…
