Select & Explain is a Chrome extension that provides instant definitions and explanations for highlighted terms without leaving the current webpage. Users select any unfamiliar word or phrase, press Alt+E, and receive context-aware explanations based on the surrounding paragraph. Designed for researchers, graduate students, and non-native readers of academic papers, technical documentation, and code, it operates entirely locally using the user's own API key, ensuring privacy with no server involvement or subscription fees. The extension supports multiple languages and allows follow-up questions within the explanation interface.

Reading dense papers in a second language means constantly tab-switching to Google. Select & Explain fixes that: highlight any term, press Alt+E, and get a context-aware explanation right next to it — it reads the surrounding paragraph, so you get what the term means in THIS paper. Unlike other AI extensions: 100% local & private (your key, your browser, zero servers), answers in any language, and a one-time $5 with your own API key — no subscription.
Stop switching tabs to Google every unfamiliar term. Select it, press Alt+E, understand it — without leaving the page.Built for researchers, grad students, and anyone reading dense papers, docs, or code in a second language.WHY THIS ONE:💬 Chat-style AI card — the explanation opens right next to your selection, and you can ask follow-up questions in the same window ("give me an example", "how is t

If you don't understand a formula or sentence, just highlight it and the tool explains it for you I built this a few weeks ago to help me read a neuroscience paper, and it works pretty well! I didn't fine-tune GPT-3, but I do take a lot of context from the paper and feed that into the prompt (not the whole paper). Ppl have uploaded AI, biology, economics, philosophy papers and even law documents. Works in Chinese, Japanese, Spanish, French and more as well!

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
