# Geistra

> Geistra is the persistent data harness for AI agents: a shared place for the information people and their AI apps work with: Spaces of records, files and plans that any AI app (Claude, ChatGPT, or any app that supports MCP connectors) can read and update, under the person's own permissions, and that they can share with the people they invite. Every record and file is searchable by exact words and by meaning (vector search). The AI can save its own analysis as records in a collection, so it lasts and others can act on it, and tasks can chain into multi-step pipelines. Every change is kept, with who made it and through which AI.

Operated by Littlejohn Partners LLC. Data is stored in the U.S. and encrypted, never used to train AI, and can be deleted at any time. For businesses, see Geistra Pro (https://geistra.pro).
