What is kuku?

kuku is a truly native, local-first markdown editor for macOS, built with Tauri instead of Electron. It stores notes as plain md files with wikilinks, backlinks, and a graph view — all without a cloud dependency. Its AI agent doesn't just chat; it searches, edits, and links your files, showing every change as Cursor-style diffs you can review before accepting. Fast, lightweight, and offline-first, kuku offers the power of Obsidian and Cursor combined, without the Electron overhead.

Who it's for

• Writers and thinkers who want a distraction-free environment where notes stay as plain markdown files, fully under their control.
• Developers and power users who need a fast, native app that respects local storage, avoids cloud lock-in, and integrates AI without sending data anywhere without permission.
• Knowledge workers managing interconnected ideas who rely on wikilinks, backlinks, and graph views to surface relationships across their entire vault.

Key features

Instant answers from your notes

kuku finds the right answer in under a second, so you never fumble mid-thought. Answers from past sessions become suggestions for future ones, keeping your thinking moving without interruption.

AI that edits your vault

The AI agent doesn't just chat — it searches, edits, and links your files directly. Every change is shown as reviewable, Cursor-style diffs, so you stay in control of what gets modified.

Offline-first, no lock-in

Your notes are yours. kuku runs locally and never sends your data without permission. Markdown, wikilinks, backlinks, graph state, and AI context all stay aligned across devices, but your files remain human-readable and portable.

Graph view and wikilink navigation

Surface related notes, links, and ideas from anywhere in your workspace in one keystroke. kuku understands structure and surfaces it intelligently, with graph consistency validated even before beta.

What stands out

"Users should never be interrupted. Every feature must serve flow state."

This philosophy drives every design decision in kuku. While other tools interrupt your thinking with sync delays, cloud prompts, or heavy UI, kuku keeps everything local and instant. The AI works alongside you, not against you — suggesting edits, linking notes, and retrieving answers without breaking your focus. It's a writing environment built for flow, not feature bloat.

Worth checking out if…

You're tired of Electron-based note apps that consume memory and lock your data into proprietary formats. If you want a native macOS markdown editor with real AI assistance — one that edits your files transparently, respects your privacy, and keeps everything offline — kuku is worth your time. It's especially compelling if you already use wikilinks and backlinks to manage a personal knowledge base and want a faster, lighter alternative to Obsidian.
