Coding agents now write code faster than anyone can read it. You hand over a task, a wall of diffs comes back, and you click accept. It works, until it doesn't, and you're debugging code you never understood in a codebase that has quietly stopped being yours. Beginners stop learning, experienced developers lose the thread, and teams drown in changes nobody really reviewed. The agents got faster. Understanding didn't. Active is an IDE built around that gap. Build at agent speed. Understand every step. With Active you can: Understand: While the agent works, Active explains each meaningful change in a short walkthrough of the real code, right in the editor: one idea per scene, with diffs, diagrams, equations and charts drawn from what actually changed and ran. Read it at your own pace or let it narrate, on device. From any scene, ask a question, ask for more detail, or request a change with that code as context. See the bigger picture: A live System Map shows your project's parts and how they connect, and redraws as agents change them. Click any part to see what it does and the code behind it, ask about it, or reshape the map in plain words. It's made for you: Tell Active who you are and what you want to follow closely or skim. Every explanation is pitched at that, and it keeps learning: say a walkthrough had too little detail and the next ones go deeper. It remembers what it has already explained, so it never explains the same thing twice. You can Orchestrate: Run many agents at once, each in its own git worktree, and let them split work across subagents. Zoom out to a live grid of every agent: rearrange it, switch layouts, and message any agent from there. Pick one and the whole workspace (Explorer, search, terminals) follows it. Active flags agents likely to conflict, and when they're done you drag one onto another to merge. The merged work stays explained. Collaborate: Host a session, share an invite code, and your team joins in seconds. Everyone sees who is watching which agent, and collaborators can send work to your agents. And More: Speak tasks with dictation. Give the agent a real debugger with logpoints and breakpoints instead of print statements. Ask how a behaviour works and get a code trace, checked by actually running it. Step away and come back to a short Catch Me Up briefing of everything every agent did.
