NoteCards

What it does

NoteCards is a knowledge management app for capturing and connecting ideas. Create private or public cards, organize them by categories and tags, and let AI automatically find relationships between your notes. Includes a knowledge graph visualization, AES-256 encryption for private cards, Chrome extension for web clipping, and an offline desktop app that syncs with the web. Built for thinkers who want to build a second brain. Available in 3 languages: English, Russian, and Ukrainian

Create notes in cards, connect ideas and build your personal knowledge base with a connection graph and end-to-end encryption.

Write thoughts into cards, connect them together and build your personal knowledge map — where ideas don't get lost, but start working together. Write a thought, idea, book note or project fragment — any time. Category, tags and auto-icon help you navigate the base quickly. Show that one thought confirms, deepens or contradicts another. AI will analyze the chain of related notes and synthesize an insight you might have missed. See not a list of notes, but a living map of ideas where everything is interconnected. Link ideas, notes and projects to see not individual records, but a system — like neurons in a brain. Search by text, tags, categories and keywords helps you instantly return to the…from notecards.app

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
