💬 Summary

Hey HN, I built Yoink AI to solve my biggest frustration with AI tools: they constantly break my workflow. I was tired of copy-pasting between my apps and a chatbot just for simple edits.

Yoink AI is a macOS app that brings the AI to you. With a simple hotkey (⌘ Shift Y), it works directly inside any text field, in any app. If you can type there Yoink can write there

Key Features:

• Automatically captures the context of the text field you're in, so you dont have to manually prime it
• Create custom voices trained on your own writing samples. This helps you steer the output to match your personal style and avoid generic, robotic-sounding text
• Yoink doesnt just dump text and run. It delivers suggestions as redline edits that you can accept or reject, keeping you in full control.

It's less of a chatbot and more of a collaborative writing partner that adapts to your workflow, not the other way around.

There's a free tier with 10 requests/month and we just launched a pro trial, which will get you 100 requests for the first 7 days to try it out!

I'm here to answer questions and would love to hear what you think - like all early stage start ups, feedback is always deeply appreciated

💬 Summary

A ChatGPT model gave researchers detailed instructions on how to bomb a sports venue – including weak points at specific arenas, explosives recipes and advice on covering tracks – according to safety testing carried out this summer. OpenAI’s GPT-4.1 also detailed how to weaponise anthrax and how to make two types of illegal drugs. The testing was part of an unusual collaboration between OpenAI, the $500bn artificial intelligence start-up led by Sam Altman, and rival company Anthropic, founded by experts who left OpenAI over safety fears. Each company tested the other’s models by pushing them to help with dangerous tasks. The testing is not a direct reflection of how the models behave in public use, when additional safety filters apply....

💬 Summary

For the better part of a year, we've watched — and reported — in horror as more and more stories emerge about AI chatbots leading people to self-harm, delusions, hospitalization, arrest, and suicide. As the loved ones of the people impacted by these dangerous bots rally for change to prevent such harm from happening to anyone else, the companies that run these AIs have been slow to implement safeguards — and OpenAI, whose ChatGPT has been repeatedly implicated in what experts are now calling "AI psychosis," has until recently done little more than offer copy-pasted promises. In a new blog post admitting certain failures amid its users' mental health crises, OpenAI also quietly disclosed that it's now scanning users' messages...

🗣️ Post 5: Show HN: AI Agent in Jupyter – Runcell

💬 Summary

I build runcell, an AI Agent in Jupyter Lab. It can understand context (data, charts, code, etc) in your jupyterlab and write code for you.

Runcell has built-in tools that can edit or execute cells, read/write files, search web, etc.

Comparing with AI IDE like cursor, runcell focus on building context for code agent in jupyter environment, which means the agent can understand different types of information in jupyter notebook, access kernel state, edit/execute specific cells instead of handling jupyter as static ipynb file.

Comparing with jupyter ai, runcell is more like an agent instead of a chatbot. It have access to lots of tools to work and take actions by its own.

You can use runcell with simple "pip install runcell" to start.

Any comments and suggestions are welcome.
