cyberWriter

cyberWriter is a native macOS editor for writers, researchers, and engineers - turns Markdown into publication-ready PDFs, Word docs, and HTML with zero external dependencies. Built in Swift and SwiftUI. No insecure community plugins for core features, all built-in natively. Full Mermaid, KaTeX, Live HTML editing and AI support and integration. Built with integrated Apple Intelligence for embeddings and vault structure / RAG chat on your whole vault. Constantly updated with new features. Now with Live API calls, pull live data right into your documents, full Vega Lite chart support, built in Excalidraw, auto image embedding from paste or drag, a fully functional terminal shell with scripting and file management features, and 3D knowledge graphs of your vault with search features.

Requires macOS 15.0 (Sequoia) or later. Apple Silicon and Intel.

cyberWriter's AI is built around your vault, not a generic chat box.
- Apple Intelligence on macOS 26+ - zero-config, on-device, no API keys
- Chat with your vault - ask questions across all your notes, get answers grounded in what you've written
- Vault structure awareness - the model understands folder layout, wikilinks, and tags, not just raw text
- Document Map embeddings (RAG) - every note is semantically indexed, so concept-level search works even when keywords don't match
- Search for concepts - find "the meeting where we talked about pricing" without remembering the filename
- Quick Actions (`⌘J`): summarize, rewrite, explain, change tone, fix grammar, continue
- Provider auto-discovery - Ollama, LM Studio, MLX, vLLM, Claude, OpenRouter, OpenAI-compatible
- Stream-to-editor - watch the AI type live into your document
- File context - attach `.md`, `.txt`, `.csv`, `.json`, `.pdf` to any prompt

Example Vault
The example-vault folder is the vault that ships with cyberWriter on first launch - open it from inside the app to explore wikilinks, the graph, Mermaid, callouts, voice notes, and flash cards in context.

In the wild
cyberWriter ranks 7 out of 60 note-taking apps by feature powerscore on the community macOS notes-app comparison sheet https://docs.google.com/spreadsheets/d/1HtJN4oQ6oBDFmFaF4Qeq5vCGEU1g-KB1DEz5Sp_OwXo - and it's the highest-ranked app in the top tier that doesn't rely on community plugins for its core features.

Why that matters: every feature here - vault, graph, Mermaid, LaTeX, AI, RAG, embeddings, voice transcription - is built into the app, sandboxed, and reviewed for the Mac App Store. There are no unvetted third-party plugins running with full system access.
