BlackLock

The all-in-one study system that connects your ideas and turns them into mastery.

BlackLock isn't just a notes app, it's a thinking tool. Capture rich notes, link concepts, visualize relationships, and instantly transform your material into flashcards and quizzes — all in one seamless workspace.

Notes That Think With You
Write in a powerful rich text editor with headers, bold, italic, highlights, checklists, and more.
Use [[backlinks]] and #tags to connect ideas naturally. As your knowledge grows, backlinks build automatically — turning scattered notes into a structured web of understanding.

Mind View (Pro Feature)
See your knowledge as a living, interactive graph.
Hexagonal nodes float in a physics-based layout, revealing how your ideas connect. Filter by tags, group by color, and fine-tune layout forces to explore your thinking from every angle.
Your notes don't just sit in folders — they form a network.

AI-Powered Flashcards (Pro Feature)
Turn highlights into study material instantly.
Generate multiple choice, select-all-that-apply, or free response flashcards with one tap. Study in quiz mode with instant feedback and score tracking so you always know where you stand.

Blackout Study Mode (Pro Feature)
Transform any note into active recall practice.
Use a precision slider to control how much content is hidden. BlackLock intelligently prioritizes key terms, nouns, and verbs to maximize retention.
Mark essential concepts with the Always Blackout highlighter so they're hidden every time — no matter the setting.

Import & Annotate
Bring everything into one place.
Import PDFs, images, and PowerPoint slides. Annotate with Apple Pencil using built-in markup tools, and keep your study materials seamlessly integrated with your notes.
BlackLock helps you move from collecting information to mastering it.

BlackLock Pro Features are available after purchase.
