Trust, then use
Invite-only. One vault per account. Each model gets a query-only grant, not a dump. This page is the honest version of how that works today.
The vault that travels with you. When a new AI ships, you start with years of history instead of rebuilding it. Models get that history as a grant. Secrets and unpublished stay home. Everything you meant to keep moves.
Anyone who switches models and will not dump everything into the next one. Invite-only. No public signup.
No. You can already download a chat export and hand it to another model. Grantfold is the layer in the middle: one map, dated notes, named grants.
Get access, create an account, then use Start to build the exact path from a ChatGPT, Claude, or Grok export, a Hermes or OpenClaw memory pack, or chosen standing notes. Then Connect Claude, ChatGPT, or Grok.
Sign in, copy that partner’s token from the vault, and follow Connect. Claude uses the MCP connector. ChatGPT uses a Custom GPT Action, or a personal Work plugin. Grok is a named partner you turn on in the vault. Do not use the Claude URL as a ChatGPT Action.
Carry was a verb on the first homepage. Grantfold is the product. Old links like /carry are a sample demo, not anyone’s private vault.
Request access on Join if you do not have a link. The owner gets an email and approves from their account. Or someone already on Grantfold sends you a 7-day invite. You choose your own email and password. They do not pick your password.
Not yet. A live invite works for anyone who has the link until it expires. Treat it like a guest code. Do not post it.
Yes. After you create the account, email and password work on a new device. You do not need a fresh invite just to sign in again.
The website and login run on Vercel in the United States (grantfold.com).
Your account record and vault live in Grantfold’s private United States store. They are not on the public pages, and they are not mixed into anyone else’s map.
Grantfold is a WCKDSMT project.
You. Other invitees cannot open your map or ask your vault. Public pages do not include it. A model only sees what you later grant, and only as a query, not as a dump.
As a one-way hash. We cannot read your password. Sessions use a signed cookie on grantfold.com. We do not put the vault in that cookie.
No. We do not sell vault data. We do not use your vault to train public models. We do not send messages as you.
Credentials, raw files, and anything that should never leave home. Coverage stays unknown until a search actually hits. House style is only what you published.
Yes, on Account after you sign in. Drop the official ChatGPT or Claude zip, the official xAI data-download zip containing prod-grok-backend.json, or that Grok JSON file by itself. A later export merges: newer subjects update, last-known stays.
Yes. Start gives you the public packer command for each agent. It reads durable identity and memory plus skill names, and refuses credential, raw-session, database, and media paths. Import the resulting JSON pack on Account.
No. This is invite-only software. If you need a certified processor before you will store something, do not put that something here yet.
Sign in, open Account, and delete your account. That removes the account and vault notes for that email. The owner can also disable or delete a member from the People panel.
