Your account
One account. One link per AI. The Mac app signs itself in.
Your sketches, captures and voice notes live in your own account. Nothing is sent to an AI until you press Serve it — and your work leaves with you whenever you like.
- Free while it's early. No card.
- A private link for Claude, another for ChatGPT — revoke either on its own.
- Export everything as a file, or delete the lot, from this page.

One more step
Check your email.
We've sent a confirmation link to . Open it on any device and you're in — this page will notice.
Nothing after a minute or two?
Look in spam, or in Promotions. The link expires after an hour, and you can send another.
Your account
Connect your AIs.
Each AI gets its own private link. Paste it once; it stays connected until you remove it here.
Your connector links
A link is a key. It's shown once, when it's made — we keep only a fingerprint, so if it's lost the fix is a new one, not a reminder.
Your new link
Paste this as the connector URL. Treat it like a password — anyone with it can reach your prompts.
Adding it
- In Claude, open Settings → Connectors.
- Choose Add custom connector, name it Preppit, and paste your Claude link as the URL.
- Start a chat and say open Preppit. The canvas appears in the conversation. On the Mac app or a phone, the same.
- In ChatGPT on the web, open Settings → Apps & Connectors → Advanced and turn on Developer mode.
- Choose Create, name it Preppit, paste your ChatGPT link as the MCP server URL, and set authentication to No auth.
- In a chat, say use Preppit to open a canvas. It renders in the conversation on ChatGPT web; the desktop app doesn't show apps yet.
Preppit for Mac
The hotkey, the frame over your screen, the shelf you can drag a screenshot onto. It signs in with this account and makes its own link — you never paste one.
The app is by invitation while it's early. Ask for it, and say what you'd use it for.

Your work
It's yours, and it leaves with you.
The export is a JSON file of every canvas, stack and note, with week-long links to your pictures and voice notes.
This removes every sketch, picture and voice note, and the sign-in itself. It cannot be undone. Type your email address to confirm.
