marka.md
the markdown editor for AI context.
What it does
Unlike generic markdown editors that treat every document as a floating note, marka.md starts with the AI context workflow; organize folders like an IDE, write with live preview, switch to reading mode for proofing, and ⌘⇧C to copy clean markdown into Claude, ChatGPT, Gemini, or any agent. Standout features: IDE-style sidebar with drag/rename/⌘⌥Z undo, live preview (mermaid + math + shiki), 5 themes, ⌘K command palette, find/replace. Notarized macOS app, open source MIT, zero telemetry.

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. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
