Tansei — A simple shelf for your Mac

What it does

Switch apps without losing the thread. The color you copied. The line from ChatGPT. The file you’ll need in a minute. Tansei keeps them pinned at the edge of your screen, ready to drag back the moment you need them. Everything stays on your Mac, private by design, no account needed. Try it free for 3 days, then pay once.

Tansei lives at the edge of your screen, so you can save anything, switch apps, and pick up exactly where you left off. Private, offline-ready, built for Mac and Windows.

A calm panel at the edge of your screen. It slides in when you reach for it and tucks away when you don’t. Right-click, drag, or just press ⌘C. Whatever you copy lands on the Shelf automatically. Groups, tags, pins, and instant search keep hundreds of items a keystroke away. Expand your Shelf into a complete workspace for how you work. Every action uses shortcuts you already know, so there’s nothing new to learn. Drag anything onto the shelf and keep working. Text, links, images, files, colors, code. The shelf stays docked at the edge of the screen while you move between editor, browser, and chat. Drag it back out when you need it. Nothing to file, nothing to search for.…from tansei.io

  Screen memory without screenshots, just text to MarkdownAug 2026 · github.com · ▲62

  It's a macOS menu bar app that reads the text of your focused window every few seconds through the Accessibility API. No screenshots, no video, or OCR. It writes plain markdown, one file per day, into a folder you choose. Point Claude Code (or anything with file access) at the folder and ask "what did I work on Tuesday?" or have it build memory about your projects. The folder contains an AGENTS.md explaining the format to the model. Thought it might be useful for someone so chucked it up on GitHub

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  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…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  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…

  Getting GLM 5.2 running on my slow computer▲937

  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▲928

  Hello! 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…
