Kuku: open source

Local-first is the right call for a second brain cloud sync always feels like a liability for personal notes. Does it handle multiple AI models or is it locked to one?

i said wish i had llm on obsidian 2 days ago and now... you guys cooked.

congrats on the relaunch. the tauri + local-first call is the right one, electron-based note apps always feel like they're fighting the OS. the cursor-style diffs for AI edits is the part that sells it for me, "AI suggests, u review" is way better than the yolo-edit pattern most tools ship with.curious where ur memory layer goes from here, is the plan to expose it as a context source other AI tools can read from, or keep it inside kuku?

Finally someone said "fuck Electron" for a markdown editor. Tauri + local-first + AI that actually writes to files instead of just yapping. Pure signal. Congrats on the launch! ⚡️

The Cursor-style edit preview is a strong trust signal—what kinds of edits does it handle well today (refactors, link hygiene, summaries), and where does it still struggle compared to manual editing?

Hi everyone, I’m one of the developers behind Kuku, mainly working on the core logic and implementation.We’ve rebuilt a lot of the product from the ground up for this launch, while thinking deeply about how local-first Markdown knowledge management can connect with an AI memory layer.Kuku is still early, and there’s a lot we want to improve. Please feel free to share anything. I’d be happy to answer as openly as I can.We’ll also be shipping frequent updates from here, so please keep an eye on what’s coming next.

How do you handle sync between devices if it’s local first, like is there a recommended setup with Git?

It’s Friday, so we’re going for it. @Y Combinator Kuku is open source, but we’re building it like a real company: a local-first second brain and memory layer for the AI era.

Hey Product Hunt 👋 I’m Minkyu Lee, design engineer on Kuku.

Our first launch started as an Obsidian-like Markdown editor. Thanks to this community, we got a ton of attention, feedback, and energy from it.

Since then, we’ve been rebuilding Kuku almost from the ground up, many late nights included.

Kuku is now open source and moving toward something bigger: a local-first second brain that can become shared memory for your AI tools.

Think plain Markdown, wikilinks, graph, search, Cursor-style AI edits, and a Mem0-like memory layer — but open, hackable, and yours.

We’re still early, still shipping hard, and looking for people who want to help shape it: users, contributors, plugin builders, and anyone obsessed with AI context.

Would love your feedback, questions, and weirdest use cases.
