Isitslop.xyz, a free AI-writing detector built on latest research
I have a weird habit of guessing whether something's AI before I check, especially on LinkedIn and Reddit (for obvious reasons). The detectors I used to confirm were mostly junk and built to sell you a "humanizer" upsell, so I went and read the actual research on what gives AI text away in 2026, then built my own (no login and free) The main sources I used are these: https://arxiv.org/abs/2406.07016 https://arxiv.org/abs/2403.07183 https://aclanthology.org/2025.coling-main.426/ https://arxiv.org/abs/2410.16107…

What it does
Most AI detectors out there either miss obvious AI phrasing or are just top of funnels to get naive students to pay, offering "human rewrites". Isitslop catches the AI in your text, tells you your "reading grade" and gives you legit advice based on your patterns, so you can be confident your writing sounds like you, all of it without ever stealing your information!
Free AI writing detector. Paste your text and see if it reads like AI.

- AFArXiv Feed – An easy way to keep up with AI research2023 · arxiv-feed.vercel.app · ▲32
Hey HN! I've always found it hard to keep up with the latest AI research, so I built Arxiv Feed! https://arxiv-feed.vercel.app/ It's basically a feed of AI research papers + a one-liner explaining what problem its solving, etc. You can also click on any paper to get a TL;DR. Right now, I've only indexed a few hundred large language model papers, but will expand to indexing AI papers in other topics. Thinking of also adding a way for people to up-vote/down-vote papers. Would love to hear any thoughts/feedback! :D Thanks!

Reliable AI-generated text detection at checkfor.ai2023 · checkfor.ai · ▲6Hey all! I've been increasingly concerned about low-quality AI generated content polluting the internet. Other AI detectors don't seem to work well in my experience, so I started checkfor.ai with a couple friends. Please give it a shot on any real text and AI-generated examples and let me know how well it works for you. Thanks for trying, I'm open any and all feedback!

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
