Best for
  • Developers wanting to integrate AI-assisted diagramming into their workflow.
  • Teams that prioritize data privacy and prefer local tools.
  • Workflows that benefit from tight coupling between code and diagrams.
  • Teams that want an AI assistant to directly operate on GitHub repos and collaboration workflows
  • Users already in the GitHub Copilot ecosystem who want a zero-deployment remote option
Not for
  • Users needing real-time multi-user collaboration (collaboration is experimental and off by default).
  • Users wanting GIF export (currently only MP4 is supported).
  • Users needing a desktop application (not yet released).
  • Scenarios where you don't want the assistant to have write access to repos (enable only read-only toolsets)
  • Environments with strict network isolation for private repos that can't reach the official remote endpoint
Required permissions
  • No API key required.
  • No network requests needed; all operations run locally.
  • May access local file system for codebase analysis.
  • A personal access token (PAT) or OAuth App token; effective scope depends on the token's own permissions
  • Enabling toolsets like actions/issues/pull_requests grants write access — request tokens on a least-privilege basis
Risks and side effects
  • Early-stage software; may have bugs or changes in functionality.
  • Codebase analysis may be inaccurate; AI-generated diagrams may require manual review.
  • Local-first means data stays in the browser local storage; sharing requires exports or viewer links.
  • Write toolsets (creating/merging PRs, triggering workflows) can cause accidental changes if the token is overscoped — try a read-only toolset first
  • In hosted mode, credentials travel via the Authorization header — make sure the client-to-api.githubcopilot.com connection is trusted
