Time to value

Quick Setup (< 1 hour)

You can use Nessie to collect and sync your work history across AI assistants, coding agents, and note apps. It automatically captures conversations from tools like ChatGPT, Claude Code, Cursor, and Codex without requiring browser extensions or manual copy-pasting. You can resume previous coding sessions, track decisions, and share specific agent runs or repository context with teammates. By providing Model Context Protocol and command-line support, Nessie allows agents to search past discussions, inspect bug traces, and build on existing code directly within your development environment.
