MCP-native context layer that gives Claude, Gemini, ChatGPT, and Copilot permission-scoped, cited company memory.

Key features

  • MCP Context Layer: Exposes shared, permission-scoped, cited organization context to any MCP-capable AI (Claude, Gemini, ChatGPT, Copilot).
  • Always-Up-to-Date Plan: Plans rewrite themselves from what was decided in meetings and threads, without anyone maintaining a document by hand.
  • Automated Reports and Stakeholder Comms: Generate audience-aware reports from a single prompt, linked back to the source meetings and decisions.
  • Drift Detection: Surfaces when reality diverges from the plan as it happens, not at the next steering committee.
  • Commitment Tracking: Every commitment made in a meeting is captured, and stalled ones surface before the next meeting.
  • Cross-Team Dependency Surfacing: Highlights the moment two teams flag the same risk or dependency across their work.
  • Fast Onboarding: Delivers months of org context — decisions, owners, history — to new hires and their AI assistants in seconds.
  • Enterprise Security: EU-hosted with GDPR compliance, ISO 27001, ISO 42001, SSO, RBAC, audit logs, EU data residency, and DPIA documentation.

Best for

  • Executive Rollups: Run the org on live memory instead of two-week-old curated slides, with metrics that update themselves.
  • PMO and Program Management: Keep execution plans, decisions, and commitments current across products and programs without manual upkeep.
  • AI-Assisted Product Work: Give Claude / Copilot in Product and Engineering the context of what was decided last Tuesday so answers are grounded in real work.
  • Sales and Marketing Enablement: Sales and Marketing teams draw on current customer insights and internal decisions when generating outbound and campaigns.
  • Compliance and Data Residency: Enterprises that need EU data residency and GDPR/ISO-certified handling for AI context adoption.
  • New-Hire Onboarding: Deliver a permission-scoped knowledge base of decisions and owners to new hires so ramp-up moves from months to seconds.
