Kuku is a truly native, local-first markdown editor for macOS — built with Tauri, not Electron. Notes are stored as plainmd files with wikilinks, backlinks, and graph view. Its AI agent doesn’t just chat — it searches, edits, and links your files, with every change shown as Cursor-style diffs you can review. Fast, lightweight, offline-first. No cloud. No lock-in. Obsidian + Cursor, without Electron.
The "reviewable diffs" concept for AI edits is brilliant - that's the missing piece that makes AI file editing actually trustworthy. How granular can the diffs get? Can it show character-level changes within sentences, or does it work at the paragraph/line level?

@curious_builder Technically, the engine handles granular diffs, but we are still researching the UX to present them in the cleanest way possible. That said, rest assured that every modification is clearly highlighted. You will always know exactly what changed before you merge.

Let’s be real—Obsidian is a beast. I used it for years, customized it endlessly, but eventually, I hit a wall.
Whether it was the plugin fatigue, the Electron heaviness, or just the UI not clicking with my brain, I found myself fighting the tool rather than writing.
So, I did what any rational dev would do: I over-engineered my own solution.

Obsidian feel without Electron fans spinning? I’m in. Tauri + plain .md + offline hits my brain. The AI doing real edits w/ diffs sounds sane, not chat fluff. I’ll poke at this for my daily notes. Curious how it handles a messy 10k-note vault.

@alexcloudstar Wow, 10k notes is a serious setup!
You've inspired me—I'm going to officially add a '10k Vault Benchmark' to our pre-release testing pipeline to ensure we stay snappy at that scale. Thanks for the challenge!

I just downloaded Obsidian but I think its time to delete it. LoL

@malithmcrdev Appreciate that! Obsidian is great — kuku is just another option if you want native performance + AI editing.
@malithmcrdev @bigmacfive I’m also a big Obsidian user. When I saw this app, I was super intrigued. What I dig most about Obsidian is how it syncs seamlessly across Mac, iPhone, and iPad. It doesn’t take up much space and keeps my notes organized without me having to pay for extra local or cloud storage. I’m really looking forward to seeing if this app can offer a similar experience.

@malithmcrdev Obsidian is a legend, but we aim to be the faster, native alternative. The good news is we both use plain .md files, so your data is safe either way. Let me know how Kuku feels compared to it!
The Cursor-style diffs for AI edits is the detail that sells me. Actually showing what the AI changed instead of just doing things behind your back-- that's the trust builder. Tauri over Electron is the right call too imo; native performance matters especially for something you keep open all day. Gonna give this a spin..
kuku
@jamespopstar Exactly. Trust is earned, not generated.
And regarding Tauri—have you seen RAM prices lately? Saving memory isn't just optimization anymore, it's financial advice! Hope it runs smooth for you.
kuku
@jamespopstar You nailed it — trust and native performance were exactly the goals. Really appreciate the kind words, hope you enjoy using it! 🙌

Really awesome. Loved your website as well

@chilarai Thanks! We tried to keep the website design as clean and minimal as the app itself. Appreciate the kind words!
Congrats on the launch! The "Obsidian" 's framing is perfect, diffs idea is a big deal too, I‘ve been using it for ages and love it, is it going to be supporting plugins eventually?
kuku
@piaobuhua Thanks! We felt that seeing the diffs is the only way to safely integrate AI into a knowledge base.
regarding plugins, extensibility is definitely a long-term goal. I’m curious though—which plugins are you currently using? I’d love to hear about your setup!
