24 alternatives to CyberWriter – a .md editor built on Apple's (barely-used) on-device AI

Apple has quietly shipped a pretty complete on-device AI stack into macOS, with these features first getting API access in MacOS 26. There are multiple components in the foundation model, but the skills it shipped with actually make this ~3b parameter model useful. The API to hit the model is super easy, and no one is really wiring them together yet. - Foundation Models (macOS 26) - a ~3B-parameter LLM with an API. Streaming, structured output, tool use. No API key, no cloud call, no per-token cost. - NLContextualEmbedding (Natural Language framework, macOS 14+) -- a BERT-style 512-dim text…

    We recently shipped the Tiptap AI Toolkit (https://tiptap.dev/docs/content-ai/capabilities/ai-toolkit/o...), which lets developers embed LLM-powered editing into rich text editors. Now we’re exploring the next step: making agents operate on documents without a browser involved. The idea is a server-side system where agents can read, write, and transform documents in real time — essentially treating your document layer as a programmable data store that agents can interact with directly. Internally we’ve been joking about the name “real-time agentic document…

    Hi HN, I'm Heberti, the solo developer working on Pinery. I've spent the last couple of years building Pinery with a single mission: I wanted a tool that bridged the gap between simple Markdown editors and complex layout software like InDesign. Pinery is my attempt at a solution. It combines a clean, distraction-free Markdown editor with a powerful, real-time visual styling mode. You can control typography, spacing, and layout visually, and see the changes instantly. Key features: - Write in Markdown with AI-assisted text tools (leveraging macOS frameworks) - Customize the design with…

    Despite the Liquid Glass controversy, our team is quite excited about the new on-device ASR model and Foundation Model Framework. It makes building local-first AI apps much easier, it was very easy to build a basic scribe app compared to our first iteration of our meeting note taker. Everything runs locally with zero cloud dependencies. With the option to combine with cloud models for more complex tasks, we hope to see more local-first AI apps. Microsoft just announced Foundry local as well, and it'll be interesting to see where they go with it. There are still some limitations with the…

    We built SwiftAI, an open-source Swift library that lets you use Apple’s on-device LLMs when available (Apple opened access in June), and fall back to a cloud model when they aren’t available — all without duplicating code. SwiftAI gives you: - A single, model-agnostic API - An agent/tool loop - Strongly-typed structured outputs - Optional chat state Backstory: We started experimenting with Apple’s local models because they’re free (no API calls), private, and work offline. The problem: not all devices support them (older iPhones, Apple Intelligence disabled, low battery, etc.). That…
