I'm Keegan. I build tools for working with AI agents.

A desktop app for running your AI agents on one project, with shared notes that survive when a conversation resets.

Long projects outlast a single AI conversation. Assembly keeps each project's decisions and unfinished work in shared notes, and saves them before the context resets, so the next agent picks up where the last one stopped.

• Works with the agents you already use, with a coordinator that splits the work and checks it. I run Claude, Codex, Gemini, Grok and Muse; add others by the command that starts them.
• Shared project notes, saved before a conversation resets.
• A preview pane beside the conversation for the documents, pages and images the agents make.
• Recurring tasks, and questions sent over from the Voyager browser.

I use Assembly to build my other projects, including Voyager.

Built with ElectronReactTypeScriptMCP

A Chromium-based browser where AI agents work in the tabs you pick, and nothing on a website changes until you allow it.

• Agents that research with cited sources, fill in forms, build comparison tables, watch a page for changes, learn a workflow you show them, or look into a broken page.
• Every click, edit or page change shows you exactly what it will do, and each approval works once.
• Type or click in the page and the agent pauses. Stop takes over at any time.

The newest build gives each project its own space in the side rail and three ways to see your tabs: as pages, as a wall of pictures, or as a board that sorts agent work by what it needs from you. Voyager Sync keeps your open tabs and bookmarks on each computer you add, locked before they leave. The recording shows that development build.
