What Nessie does

Nessie provides a shared context layer for you, your team, and your AI agents. It auto-syncs AI conversations across providers and structures them into queryable, trustworthy context that both humans and agents can draw on, giving users transparent control over their memory.

Key capabilities

  • Auto-sync of AI conversations across ChatGPT, Claude, Gemini, Perplexity, Claude Code, and Codex
  • Structured, queryable context available to both humans and agents
  • Visible, editable notes that users can shape or delete at will
  • A unified memory layer so agents are not amnesiac across tools

Who it's for

Nessie is aimed at individuals, teams, and organizations deploying many AI agents. Its premise is that AI-native organizations will be small teams running large numbers of agents that need shared, persistent context. The company was founded by two Yale CS graduates and former Amazon engineers and is backed by Y Combinator and other investors.
