In plain words
Kuku is a native macOS markdown editor for local note-taking that stores files as plain text with wikilinks, backlinks, and graph visualization. Built with Tauri rather than Electron, it works entirely offline without cloud dependency or vendor lock-in. The editor includes an AI agent that searches, edits, and links notes while displaying all changes as reviewable diffs. It targets writers and knowledge workers seeking a lightweight alternative to Obsidian with integrated AI capabilities.

OpenKnowledge – open source AI-first alternative to Obsidian/NotionJun 2026 · github.com · ▲381Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents.

I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
