AlliHat▲96I think we all have a similar flow and pain with browsers and AI. Copy article, paste in Claude tab, come back to article, back to Claude, in circles we go. Anthropic has a Chrome extension, but my daily driver is Safari. So I made my own extension. It's not a clone as I've never used the Chrome version. One obvious change: the Chrome version I believe uses Chrome "request sidebar" thing. And Safari doesn't have that, so had to inject the sidebar right in the site html itself. There's been some fun things in here like figuring out the sidebar html/css sandboxing. Also there's an agent…

OpenUI▲322Thesys just open-sourced their generative UI rendering engine. Interesting timing given where Google a2ui and Vercel's json-render are headed. The difference worth noting: a2ui and json-render both treat JSONL as the contract between the LLM and the renderer. Thesys is betting that's the wrong primitive. Their engine uses a code-like syntax (OpenUI Lang) instead — LLM writes it, renderer executes it. The argument is that LLMs are fundamentally better at generating code than generating structured data, so you get cleaner output and ~67% fewer tokens. The broader vision seems to be a…

I recently published a new package on npm that brings the Anthropic APIs to React Native without polyfills. The library supports chat streaming and normal chat completions. The goal of the library is to follow the Node SDK wherever possible while taking advantage of React Native SSE for streaming where the Anthropic Node SDK does not work. Lmk what you think or if this will be useful to you!

Hey HN, Open artifact is an easy way to view your docs, html artifacts and collaborate with others. I like to keep my stack llm agnostic. My default way is to read docs via markdown and visualize reports via html. But sharing it with colleagues and keeping track of it was a big pain. I like claude artifacts but I don't like to get tied to a single provider. So, I built open artifact. Open artifact is free. You can host it yourself too. Hope you find it useful.

I run a small AI lab and playground and got super excited about Anthropics paper "Verbalizable Representations Form a Global Workspace in Language Models" (https://transformer-circuits.pub/2026/workspace/index.html) It talks about how they use a tool they call a Jacobian Lens to view inside the middle layers of LLM while it's working before it commits to a word (token). I wanted to see if I could get a version of this running on the open models and to my surprise it worked! I ran some experiments with it and build a public facing free tool anyone can use with your…

Hi, I designed and developed a spatial index that maps museum artefacts as connecting arcs/hyperlinks from their origin site to institutional location/sources. The Index specifically looks at western/euro-american institutions and maps their collection categorised by them under Islamic art, Asian/African art, ethnological collections, Middle East, South America etc. Started as my MA thesis in 2022, kept building since, mostly solo with a little funding. Fully open source, self-hosted, AGPL-3.0, Next.js + Deck.gl on the frontend, Strapi backend, Python ETL pulling from…
