What is Capacities?
Capacities is a modern note-taking and personal knowledge-management tool built around an object-based model. Instead of organizing everything into folders and flat documents, Capacities treats your notes as connected objects — people, books, ideas, projects, meetings — each with its own structure, that link together into a rich, navigable network. This object-centric approach makes it natural to build a structured "second brain" where information is organized by what it is and connected by how it relates, rather than buried in a folder hierarchy.
Its strengths are structure, connection and a thoughtful, pleasant design. By giving different kinds of content their own object types, Capacities helps you capture and find information in a way that mirrors how you actually think, and the linking between objects surfaces relationships and context as your knowledge base grows. It strikes a balance between flexibility and structure that appeals to people who want more organization than a simple notes app but find heavier tools overwhelming. The clean, focused experience makes building and revisiting your knowledge genuinely enjoyable.
Capacities is a great fit for students, researchers, writers and knowledge workers who want an organized, connected, object-based system for their notes and ideas — a structured second brain that is still approachable. It sits alongside tools like Notion, Obsidian, Tana and Reflect in the personal knowledge-management space, distinguished by its object-based model. If you have struggled to keep your notes organized and connected and want a tool that brings natural structure to your thinking, Capacities is a refreshing, well-designed option worth trying.
What is Outlier?
Outlier is a free, unlimited Krillion-style word game that you can play in your browser with no account and no daily cap. Each round gives you a prompt, such as naming a kind of fruit, a movie, a city or a household object. You type an answer that fits the prompt, and the game scores you by how rare your answer is compared with what other players typed. The rarer and more original your answer, the further your UFO flies. Common answers barely move you, while a clever, unexpected one can launch you far ahead. Unlike games that give you a single puzzle per day, Outlier lets you keep playing as long as you like, so you can practise, chase a better score, or just kill a few minutes. It is built for people who enjoy trivia, word games, daily puzzles and party-style games, and who got hooked on the Krillion format but ran out of rounds. Rounds are short, the rules take a few seconds to learn, and there is nothing to download or pay for. You can play alone to beat your own best, or compare results with friends to see who thinks most differently. The prompts are varied and refreshed often, covering everyday topics, pop culture, food, travel, nature and more, so the game stays fresh. Playing well is a mix of vocabulary, creativity and a little psychology: you have to guess what everyone else will say, then avoid it while still giving an answer that truly fits. That tension is what makes each round fun and slightly addictive. Outlier works on phones, tablets and desktop browsers, loads quickly, and keeps score as you go. If you are looking for games like Krillion, an unlimited Krillion alternative, or a rare-answer trivia game to play whenever you want, Outlier is a simple free place to start. Try a round now and see how original your answers really are.
