File-scoped rules
Memory rules carry applies_to globs and risk tags. Select a file,
see the architecture rules that govern it, ranked by specificity.
Now shipping on the Mac App Store
Stop briefing your AI agent on the same codebase every day.
Kujto Studio is a local-first Mac app that reads your repo's memory, then shows the rules that apply before you touch a file. Architecture, risks, related tests, the agent context to inject, in one panel.
The product
Before you touch this file.
Every repo has hidden rules. New agents forget them. New developers miss them. Old decisions live in PRs, READMEs, Slack threads, AGENTS.md, and a dozen scattered docs. Kujto Studio makes that mess visible in the moment you need it.
Confidence verdict
Safe, needs context, or danger zone. A single badge tells you whether the file is calm ground or a place a fresh agent will quietly break.
Memory linter
Catches stale rules, broken links, and missing governance files before they cost you a pull request. Deterministic, no AI.
Agent context injector
One click renders the rules for the current file as a prompt block you can paste into Claude, Codex, Cursor, or any editor with an agent.
Multi-agent wire
One source of truth, symlinked into CLAUDE.md, CODEX.md,
GEMINI.md, and AGENTS.md. No duplicated memory.
Local only
Your repo stays on your machine. Nothing is uploaded. Memory is Markdown in your repo, versioned in git, reviewed like any other change.
Where it lives
One engine, five surfaces.
The same memory index drives the Mac app, an Xcode Source Editor extension,
a VS Code or Cursor extension, a menu bar helper with Shortcuts, and the
kujto CLI. Use one, use them all.
