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

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.
cyberWriter ranks #7 of 60 note-taking apps by feature powerscore on the community macOS notes-app comparison sheet - 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. The direct-sale build is the same binary as the App Store build; the only difference is how it gets updates and how the license is checked.
cyberWriter is a commercial product. This repository hosts public release binaries, the example vault, and documentation - the source code is private.
