| Description | Capacities is a note-taking and personal knowledge management app that structures everything you capture—people, books, projects, ideas—as connected objects with properties rather than flat pages in folders. Objects link to each other to form a knowledge graph, with backlinks and automatically surfaced related content revealing connections between notes. It also includes an AI assistant that writes, summarizes, and surfaces links between objects, and centers daily notes as a low-friction inbox for capturing thoughts. | Aider is the open-source AI pair programmer that works in your terminal with your existing codebase. It edits files and commits to git automatically, supports 100+ LLMs, and consistently tops AI coding benchmarks — the choice of developers who want full control. |
