Your inbox, read and drafted as you.
A script you deploy in your own Google account reads, sorts and drafts your mail. A draft goes out only after you say send.

Draft, redraft, send on your go
Files attached from Drive; the draft you approved goes out as it stands.
Attachments, read or filed
One file's bytes straight back, or every file saved to a Drive folder.
Labels, read state, cleanup
Unread counts per label; a sender's mail trashed in batches.
where the credential stays
Gmail access you granted to yourself.
You authorise Gmail once, for a script in your own account.
in your Google account, and in your secret store
Your deployment, executing as you, and its key, made by you and kept in your store. Mail moves between your computer and Google only. No connector's server reads it on the way.
in your brain
A page in your space names the deployment and the key. No value, no mail.
what instibrain never touches
What never happens to your mail.
The script reads and drafts as you. A send waits for your go.
- A send without your go.
Each draft waits in Gmail until you say send.
- Mail stored with us.
Messages travel between Google and your computer, never through our server.
- The key in a URL.
It rides in the request, read from your store at that moment.
the limits
Mail your AI trashes still counts toward your storage.
It comes from Gmail itself, not from the script.
| Limit | What it means |
|---|---|
| Trash still counts toward storage | Gmail empties it after 30 days. |
before you connect it
Your AI reads your mail, and our server never does.
Will the AI ever send a mail?
Only after your go. It sends the draft you saw, as it stands.
Why not reach Gmail through a connector?
Your own deployment runs as you, across your whole mailbox, called straight from your computer. No other company's server holds your mail on the way.
Does instibrain read my mail?
No. Our server stores a page naming your deployment, never a message. The script runs in your account.
Your inbox, sorted and drafted as you.
Deploy once. Claude Code and Codex then read and draft your mail as you, and send on your go.
