What it does
I got tired of openingmd files in Notepad and seeing raw syntax everywhere, but Obsidian felt like overkill when I just wanted to edit one file. So I built Paperling. It renders math, chemistry, Mermaid diagrams and code live as you type. There's an optional AI that proposes edits as inline diffs you accept or reject, and it works with any OpenAI compatible endpoint including local models. Built with Tauri and Rust so it's fast and tiny. Free, open source, Windows, macOS and Linux.
A fast, native, open-source Markdown editor with live preview, split view, KaTeX math, chemistry equations, Mermaid diagrams, slash commands, and an optional AI assistant. Free for Windows & Linux. Built with Tauri + Rust + React.
Paperling is a fast, native Markdown editor that renders math, chemistry, and diagrams live as you type, with an optional AI that proposes edits you accept or reject right in your text. Split view: raw Markdown on the left, the live preview on the right. A focused writing surface with the power features pros expect, and a few you won't find elsewhere. Chat about your document, or let Agent propose edits as an inline diff you accept or reject. Bring your own model. Rendered reading, raw source, or both side by side with bidirectional scroll sync. KaTeX for inline and block math, plus mhchem for equations, ions, and isotopes. Flowcharts, sequence, class, state, gantt, ER, and mindmaps render…from razee4315.github.io

An open-source, collaborative, WYSIWYG Markdown editor2023 · editor.vrite.io · ▲460Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…
OpenKnowledge – open source AI-first alternative to Obsidian/NotionJun 2026 · github.com · ▲381Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins. So we built OpenKnowledge. It takes…
FlowershowMar 2026 · flowershow.app · ▲174I'm Rufus, one of the founders of Flowershow. We love markdown and use it everywhere from making websites, to docs, to knowledgebases. Plus AI splits it everywhere now. Got tired of the framework/config/deploy overhead every time we wanted to share a file or put a site online. So we built the thing we wanted. Files in. Website out. "Vercel for Content" is our aspiration - make deploying (markdown) content as fast, seamless and easy as Vercel did for JS. Command line plus you can connect to github repos, use Obsidian via plugin, or drag and drop files. npm i -g…

Talanoa▲340Hi 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 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…
