Local-first "second brain" with live connectors to Claude Code, GitHub, Jira, Slack, Gmail.

Desktopfreemiumglobal

Poltergeist is a local-first personal knowledge base that connects directly to the tools people already use for work, including Claude Code, GitHub, Jira, Slack, Microsoft 365, and Gmail. It's built for knowledge workers who want their notes to stay current with what's actually happening in their other tools, instead of a static notes app.
