Uses

Private, with its limits

Your work stays near you. Here is where it stops.

Calling something private means little without its edges, so these are ours: what stays on your device, what has to travel, and what cannot be taken back.

  • Stored in this browser

    Conversations, pictures and drafts sit in your browser's own storage. This site keeps no copy and has no account to attach one to.

  • A message does leave

    To get an answer, what you send goes through our server to the model provider. We write none of it down. The provider's own retention rules are theirs, and we cannot change them.

  • No sign-in

    No email and no password. A wallet comes in only if you want to anchor something on chain, and it is never needed to chat.

  • Delete is one click

    One click removes a chat from this browser, another clears everything. It cannot recall what a provider already received, or a hash you put on chain.

Sexual content, real people, and malware are refused in every mode. No setting turns that off.Read the privacy page

Build

Checking

A small app from one sentence.

Say what it should do. The model drafts one file, the sandbox runs it next to the code, and you decide what happens next. It is a draft: read it before you trust it.

Start building
  • One file, nothing else

    A draft is a single HTML file with its styles and script inside. Read it, keep it, open it anywhere.

  • Runs sealed

    The frame allows scripts and nothing else: another origin, no storage, no network, no reach into this page or your wallet.

  • Code beside the result

    Switch between the source and the running app, edit by hand, and run it again. It is a draft, so read it first.

  • Change it in words

    Ask for a change and the model rewrites the file. Your earlier draft stays until you replace it.

  • Start from a sample

    Four small apps we wrote ship with the site. They run without a key, so you can try the sandbox first.

  • Hosting comes later

    Publishing at a public address and databases are planned. For now, download the file and host it yourself.

Practice mode

Keep a record of what you made.

Optional, and separate from everything above. Choose a file, and a wallet writes its hash on chain with a version history. The contract holds no money, has no owner, and costs only gas.

The hash · your wallet writes itVersions · author or editorsAttests · other wallets
  • A hash, not your file

    Your browser computes the hash and the file stays with you. Any label or link you add is public and stays on chain for good.

  • A second wallet attests

    Another wallet can say it has seen a version. A wallet that was ever the author or an editor of that record cannot.

  • It proves less than it sounds

    A record shows this wallet published this hash at this time. It does not show who made the work, or that the work is original.

Nothing to sign up for. A wallet is only for the on-chain part.
