Obsidian — but a lot has changed

Its standout feature is an integrated AI agent that not only chats but actively searches, edits, and links files, presenting changes with Cursor-style diffs for transparent review. This combination of traditional note-taking with AI-driven enhancements makes Kuku ideal for writers, researchers, and productivity enthusiasts seeking a seamless, privacy-focused environment.
