Yank Note
“A highly extensible Markdown editor, designed for productivity” — purocean‘s Electron/Vue/TypeScript desktop app, AGPL-3.0, 6.7k★ / 925 forks, on Windows, macOS and Linux. T1 as an official project repository; the claims below are the project’s own, and the interesting ones are its warnings.
It sits in this wiki’s tools-for-thought roster beside obsidian, logseq and roam-research, and it differs from all of them in one respect: the note runs.
Local markdown, kept deliberately plain
The storage bet is the same one this wiki’s whole lineage makes: “Data is saved as local Markdown files, and extension functions are implemented in the original syntax of Markdown as far as possible.” Features are added without inventing a proprietary document model, so the notes survive the editor — the property obsidian is valued for here.
Per-file encryption is offered for names ending .c.md, done in the front end, one password per file,
with a warning that has the right shape: “Once the password is lost, it can only be cracked violently.”
The note as a program
Yank Note embeds runnable code blocks — JavaScript, PHP, Node.js, Python, bash — executed from inside the document, alongside PlantUML, Drawio, ECharts, Mermaid, mind maps and embedded HTML applets. Document history is tracked in-app, and an AI Copilot (OpenAI, Ollama, Gemini, Kimi and others) writes text and images into the same document.
That combination is executable-markdown, and no other tool in this wiki’s roster has it. A Zettelkasten slip is inert by construction; an Obsidian vault renders. Here the file is closer to a notebook: a record that also acts.
The warning the project prints on itself
“Yank Note sacrifices security protection (command execution, arbitrary file reading and writing)”
for extensibility, with the corollary that opening an untrusted Markdown file is dangerous. Stating that plainly is more than most tools in this category do, and it is the most useful sentence in the README for this wiki, because of what the rest of the corpus is about.
The llm-wiki pattern has a machine writing markdown files continuously, and this hub is an instance of it. Point an editor with command execution at a corpus an LLM maintains from web sources, and a code block is no longer only a note — it is an execution primitive that arrived through the same pipe as the prose. The AI Copilot closes the loop inside one product: the model writes into a document the editor can run. Nothing in the README says the copilot’s output is treated differently from a human’s, and there is no reason to assume it is.
None of this makes the tool unsafe to use on your own notes. It makes the trust boundary explicit, and this lineage has not had one.
