Paid

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.

Free

Self-hosted persistent memory layer that lets Claude, ChatGPT, Cursor, and any MCP client share the same evolving context.

Key features

  • Cross-Tool Persistent Memory: One memory layer shared by Claude, ChatGPT, Cursor, Codex, and any MCP client.
  • Semantic Recall: Retrieves memories by meaning rather than exact wording, so different phrasings still surface the right note.
  • Memory Graph (v2): Memories link automatically or explicitly, and recall can follow hops to surface related context.
  • Notion Sync: Connect a Notion workspace and shared pages sync into memory nightly or on demand, staying current as they change.
  • Self-Hosted on Cloudflare Workers: Deploy to your own account in about two minutes — memory stays under your control, not a vendor's.
  • MCP Tool Set: remember, append, update, recall, list_recent, forget — usable directly from any MCP client or the brain CLI.
  • Graceful Degradation: If Vectorize is missing, recall falls back to keyword search with a clear notice and a /health endpoint reports index status.
  • Dashboard with Graph View: Web dashboard for browsing memories, managing integrations, and exploring the memory graph visually.

Best for

  • Consistent Assistant Context: Keep the same project background, preferences, and decisions across Claude, ChatGPT, and Cursor without repeating yourself.
  • Team Knowledge Capture: Use the CLI or MCP tools to store product decisions or interview notes so any AI tool can recall them later.
  • Notion-Backed Memory: Share Notion pages with the connection so meeting notes and specs are automatically retrievable by any AI client.
  • Self-Hosted Compliance: Run memory in your own Cloudflare account when data cannot leave your infrastructure or be locked in one AI platform.
  • Developer Journaling: Save decisions and rationale from your terminal (`brain remember`) and recall them from Cursor while coding.
  • Research Continuity: Store leads, references, and open questions once and surface them across whichever assistant you're using that day.
