What permanent storage is good for
Creators, legal and property teams, archivists, developers and AI agents use bitty.cat to keep files online for good.
Creators
Music, video and artwork you want online at a fixed link for good — not until a hosting bill goes unpaid. Upload the master once; share or embed the link anywhere. See the dedicated apps for music, video and images.
Lawyers, deeds, titles and escrow
Deeds, title documents, closing files and contracts, kept as a copy nobody can edit or take down. Read more ↓
Records and archives
Documents, photos and files you may need to prove existed on a given day. Each upload is paid for with a Solana transaction, which is a public, timestamped record.
Developers
Store assets, metadata and user files through a REST API and stop thinking about retention. See the developer page →
AI agents
Agents can write and read persistent memory and files through the same API. Read the docs for the agent-memory endpoints.
Permanent storage for legal documents, deeds and closing files
For lawyers, paralegals, title and escrow officers, brokers and property owners: a permanent reference copy of a document — one that cannot be edited or taken down, at a link that outlives your file server, your vendor and us — paid for once.
What a permanent copy is good for
Deeds, title documents, closing packets, leases, contracts, court filings you have already filed, photos of a property on a given day. Anything you will need to produce years from now exactly as it was.
What happens to the file
- Stored on Arweave, a public network whose storage endowment is designed to pay for data for more than 200 years.
- The stored copy cannot be edited — by you, by us, or by anyone.
- Each upload is paid with a Solana transaction: a public, timestamped record that the upload happened.
- Priced by file size, paid once per file in SOL. No seats, no subscription.
Keep client documents private
Unencrypted files on Arweave are public to anyone with the link. For anything confidential, hold a Bitty Kitty NFT and encrypt the file in your browser before it leaves your device. We never see the key. You receive a recovery key; lose both your wallet and the recovery key and nobody can decrypt the file.
Share closing documents on your terms
From my.bitty.cat, make a share link with an expiry and a view limit, and revoke it any time. The link is ours to control; the Arweave copy underneath is not.
What this is not
bitty.cat keeps a permanent copy. It does not record a deed, close an escrow, or insure a title. Keep using your county recorder, your escrow agent and your title insurer.
The Solana record shows when the upload was paid for. It does not show when a document was signed, or what it says. It is not a notary's seal.
This is not legal advice. Your own rules on retention and confidentiality apply — check them before you upload.
Can it ever be deleted?
No. Not by you, not by us, not on request. We can remove a file from our links and apps; we cannot remove it from Arweave. That cuts both ways: nobody can make your copy disappear, and you cannot either. So encrypt anything sensitive, and think before you upload — if a document may one day have to be destroyed, an unencrypted permanent copy is the wrong place for it. An encrypted copy stays unreadable without your wallet or recovery key, but the encrypted bytes remain.
Questions from lawyers and title teams
Not a fit
Files you expect to edit or delete later — permanent means permanent. Anything you would not want public: use encryption, or do not upload it.
