Skim

What it does

Skim is a free, open-source (MIT) email client for Windows. ✂️ Minimal on purpose: no calendar, no rules engine, no bloat. Fewer buttons, less cognitive load. ⚡ Native Rust core (Tauri 2): ~5 MB installer, sub-second cold start, instant full-text search. 🔒 Local-first, offline-ready, zero telemetry. ✦ AI on your terms: bring your own Anthropic or OpenRouter key and Skim drafts replies in your voice and answers questions across your whole mailbox.

Skim is a free, open-source email client for Windows with a built-in AI copilot. Native Rust core, ~5 MB installer, offline-first, instant search — bring your own AI key.

Minimalist, native, fast. BYOK for the AI assistant and co-writer. No subscriptions — free forever. Open source. Email clients usually come in two flavors: a browser cosplaying as an app, or a monstrous do-everything suite with ICQ-era vibes. Skim is neither. A Rust core with a system WebView2 UI — no bundled browser like Electron. The installer is a few megabytes, cold start is instant, idle memory is modest. Installs without admin rights. No calendar, no contacts manager, no rules, no filters, no snooze — none of the stuff you never actually use anyway. Fewer buttons means less cognitive load means less irritation. Need a do-everything suite? Install Outlook. Buttons appear only when…from skim-tech.com

In the maker’s words, at launch

I built Skim because I was super dissatisfied with all existing Windows clients. I mean, it's not a rocket science, there should be some lightweight modern solution, isn't it? So I decided to create a client that just, you know, MAKES SENSE and has design younger than dinosaurs. Key points: * Obsessed with installer…

  SKI is a on-device voice coding application, which can be used with any agents that supports skill, such as Claude Code, Codex or Hermes. It transcribes your voice (which you can optionally review and edit) and send it to the connected agent. The agent then completes the task, and uses the skill to talk about the updates of the project or a summary or a query using voice. This runs completely on-device. Free. No subscription. Available on both Mac (notch and pill) and Windows (pill widget) It can also be sent to meetings with the intelligence of the connected project to participate actively…

  Hi guys, Just letting you all know that i've just launched the beta version of Skim.it The smart way to save, sort and share the best of the web. We are trying to solve the problem over information overload on the web and not being able to fins the time to read and remember useful content you discover online.

  Core – open source memory graph for LLMs – shareable, user owned2025 · github.com · ▲112

  I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps. The deeper problem 1. Not portable – context is vendor-locked; nothing travels across tools. 2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance. 3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried. Demo video:…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  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.…

  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…
