  • Stop copy-pasting context by using one shared memory across every AI you already pay for
  • 682 built-in actions your AI can take, each one logged and requiring approval before sending
  • Hard billing ceiling at your plan price—AI pauses rather than surprise charges
  • Separate workspace per client, product or team with unified view across all
  • Independently tested security with AES-256-GCM encryption and Google verification
  • Built-in MCP server in every product, no separate AI add-on or cloud service needed
  • Production data remains on-premise; nothing sent to cloud unless user's chosen AI model requires it
  • Drafts protect production: AI-created screens and dashboards reviewed before going live
  • Same access controls for AI as for people: roles, rights and logging
  • Assists in user's own language and explains PLCGateway features through built-in help
