Persistent data harness for AI
The data harness
for your AI agents.
Your AI does the thinking. Geistra keeps what it works on: your records, files and saved analysis, searchable by word and by meaning, shared with the people who matter, and there in ChatGPT, Claude or whatever comes next.

Today, everything you build with AI is stuck in one app.
Switch assistants and you start from zero. Plan with your family and you copy and paste between chats. Geistra separates the intelligence from the information: the AI does the thinking, and Geistra keeps the state, safely and portably.
What a data harness is
The part of your AI that remembers
The AI model
Thinks
ChatGPT, Claude or Gemini reads, reasons and writes. When the chat ends, what it worked out goes with it.
The connector
Plugs in
MCP is the standard plug that lets an AI app reach outside tools. It carries requests; it doesn't keep anything.
Geistra
Keeps
Your records, files, findings and history: searchable, versioned and shared under your permissions, ready for the next conversation, person or AI.
How it works
Three steps, then just talk to your AI
- 1
Create a Space
A home for something you care about: your family, a trip, a client, a team. Ask your AI: “Create a Family Space.”
- 2
Connect any AI
Add Geistra to ChatGPT, Claude or any assistant that supports MCP connectors. Each one gets its own permissions.
- 3
Bring your people
Invite family or teammates. They use their own AI, and everyone works from the same up-to-date information.
Why Geistra
Built for people and their AIs working together
Structured, not just chat
Your AI can set up collections for anything (trips, contacts, receipts) and keep real records in them to query and update, not buried in a transcript.
Search by words or by meaning
Every record and file is searchable by exact words and names, and vectorized for meaning, so “that place with the view” finds the right hotel.
Analysis that lasts
Your AI can save its analysis as records in a collection, not a reply that scrolls away. Your family, or another AI, can pick it up and act on it.
Multi-step pipelines
One step's results can start the next: a new receipt is read, its totals land in a collection, and a monthly summary is built from those, even with no chat open.
Every change remembered
Each edit is a new version. See who changed what, through which AI, and why, and every earlier version.
No silent overwrites
If two people change the same thing, Geistra stops and shows both versions, so your AI can ask which one is right.
Your AI never outranks you
An AI gets at most your access, and sensitive actions like inviting someone always wait for your approval.
Context that travels
Save a planning conversation into a Space and pick it up later, or hand it to someone else, in any AI.
Yours to keep
Geistra stores only what you deliberately save, and it's never used to train AI. Delete it whenever you like.
One trip, two people, two AIs
Everyone stays on the same page
Jeremy plans in ChatGPT. Jill prefers Claude. Their Italy trip lives in their family’s Geistra Space, so each of them sees the latest, and each change is attributed.
Request access →Jeremy → ChatGPT
“We’re going to Italy June 8–18. Jill and Georgia are coming.”
Jeremy → ChatGPT
“Invite Jill to the Family Space.” Geistra asks Jeremy to approve first.
Jill → Claude
“What trips do we have coming up?” Claude finds Italy.
Jill → Claude
“Change my arrival to June 9 and add my flight.”
Jeremy → ChatGPT
“What changed with Italy?” It reports Jill’s edits, made via Claude.
Families
Trips, schedules, recipes, household paperwork: one place every family member and their AI can use.
Teams
Clients, projects and decisions that survive whichever assistant each person prefers, with approvals for sensitive changes.
Builders
A versioned, permissioned data layer with a REST API and an MCP server, so your agents share state safely.
