Paperling
Open a markdown file and just write. No vault, no setup.
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.
Hey Product Hunt! I'm Saqlain, a AI student and the maker of Paperling.
This started from a really small frustration. Every time I double clicked a README or my notes, Windows opened it in Notepad and I'd stare at a wall of asterisks and brackets. Obsidian is great but asking me to create a vault just to read one file always felt like too much ceremony.
So Paperling does one thing: you open a markdown file and it just works. Live preview, split view, and the stuff I personally kept missing in lightweight editors, like KaTeX math, chemistry equations, and Mermaid diagrams rendering as you type.
The AI part is optional and bring your own model. You can point it at OpenAI, Gemini, or a local Ollama instance. When it suggests changes they show up as green and red diffs right in your text, and nothing gets written until you approve each one. I didn't want an AI that rewrites your file behind your back.
It's built with Tauri and Rust, fully open source under Apache 2.0, and free. Hundreds of people are already using it since the GitHub release and their feedback shaped a lot of v1.0.
Would love to hear what you think, and if there's a feature you wish every markdown editor had, tell me. I ship updates fast. 🙂
