Mac Version Website โ bullet.overio.space - Bullet is a focused outliner for structured thinking. - Most ideas do not begin as finished documents. They start as fragments: a sentence, a question, a few scattered points. Bullet helps those fragments grow into structure. You can create branches, nest ideas, collapse details, focus on a section, and shape your thinking before turning it into writing, plans, research notes, or product ideas. - On iPhone, Bullet gives you a clean, portable outline workspace for capturing and organizing thoughts wherever they happen. Your outlines sync with Bullet for macOS through iCloud, so you can continue working across devices. - Bullet is useful for: - Capturing ideas and messy notes - Building article, video, course, or presentation outlines - Breaking down product ideas, requirements, and decisions - Organizing reading notes, research threads, and project context - Turning complex problems into expandable branches - Core features on iPhone: - Nested outline editing - Fast branch creation, indentation, folding, and reordering - Focused navigation through branches - Markdown-style text support - iCloud sync with Bullet for macOS - A calm interface for thinking in structure - Bullet for macOS also supports AI-assisted workflows for expanding, organizing, and rewriting outlines. The iPhone app focuses on capture, editing, navigation, and sync. - Bullet is not a generic notes app. It is a thinking space where ideas start as branches, then gradually grow into finished work.

Second Brain Link turns the data you already own into a private, AI-queryable "digital twin" that lives entirely on your device. Your LinkedIn, Facebook, Instagram, and Google exports are unpacked, de-duplicated, and linked into one knowledge graph โ right on your phone. Nothing is uploaded. There's no account, no tracking, and no cloud. WHAT YOU CAN DO โข Build your brain from the data exports you request from each platform โข Explore an interactive graph of the people, companies, and topics in your life โข Talk to your twin โ ask questions and get answers grounded in your own notes โข Keep everything 100% on-device and private by design WHY IT MATTERS Your most valuable context โ who you know, what you've done, what you care about โ is trapped in export archives nobody ever opens. Second Brain Link hands it back to you, working. Your data already exists. It's already yours. It's time it started working for you.
