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.

About

Second Brain Link

Read full description

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 โ€ข Build your brain from the data exports you request from each platform โ€ข Explore an interactive graph of the people, companies, and topics in your life โ€ข Talk to your twin โ€” ask questions and get answers grounded in your own notes โ€ข 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.
