A WYSIWYG Markdown editor for the AI era. Open the .md files your AI just gave you, edit like Word, save as plain .md. Math, citations, no syntax to learn. macOS, Windows, Linux.
You didn't ask for .md — your AI just gave you one. MDX opens it like a document so you can tweak a sentence, fix a heading, drop in a table, and save it back. No syntax to learn. Markdown is great. Typing **asterisks** every time you want bold is not. MDX lets you format with a click — the file on disk is still plain markdown. Tables, code, math, diagrams — every one of them lives behind a button. No syntax to memorize. Tab File tree. Tabs. Word count. Status bar. Native menus. The kind of editor you can leave open for a year. Bold, italic, headings, lists, math, tables, diagrams — every kind of formatting lives behind a button. Your file on disk stays plain markdown.

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai



Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it.
