For developers and AI

Encrypted file sharing your code and your AI assistant can use.

Send files and secrets from a terminal, a script, or Claude, ChatGPT and Cursor. Everything is encrypted on your machine, so neither the model nor our servers see the content.

How it works

  1. From the command line

    npx @deltabreen/share send report.pdf --to client@example.com sends a file or a folder as one link, on every plan, with --json for scripts.

  2. From your AI assistant

    Connect Claude, ChatGPT, Cursor or Claude Code once, then ask it to send a file. It gets the link and the activity, never the file or its key.

  3. From your app

    A REST API with OAuth sign-in on every plan and API keys from Studio. Ask someone for a file with an upload link, and read who downloaded what.

What you get

  • A local MCP server on every plan, and a hosted connector from Studio
  • Upload links: someone sends you a file through a link your script makes
  • Secrets that open once, sent from a file so they never pass through the chat
  • Activity and receipts for every link, in JSON

API examples

Common questions

Can the AI read my files?
No. The file is encrypted on your machine before it leaves. The assistant sees the link and the activity, never the file or its key.
Which assistants work?
Claude (on the desktop and the web), ChatGPT, Claude Code, Codex CLI, Cursor, VS Code, Antigravity and any other client that speaks MCP.
Is there an API?
Yes, under /api/v1, with OAuth on every plan and API keys from Studio. The API examples page has curl and JavaScript for the common calls.
