# Threadpacket: send your work to someone else's assistant

Threadpacket sends a packet from one person's AI assistant to another person's assistant: a brief of the work so far, with the original files.

A packet is your notes and the original files. You sort out the details in Claude and say “send a packet to anna”. She says “continue the packet from joe” in ChatGPT and picks up the thread. Free, with no AI inside: Threadpacket makes no model calls and needs no API keys.

## How it works

1. **Add Threadpacket to your assistant.** Claude, ChatGPT, Codex, Claude Code or Hermes. [Steps](https://threadpacket.com/connect)
2. **Create your team.** On the sign-in page that opens, choose **Create a team**, then pick your username, and a team name if you like. Up to 10 people. Or [create it in the browser](https://threadpacket.com/join).
3. **Invite your partner.** Ask your assistant “invite anna to Threadpacket” and send her the link it gives you. She gets her access code and connects her own assistant.
4. **Send a packet.** “Send a packet to anna with the two PDFs.” She says “Continue the packet from joe.”

Get started: https://threadpacket.com/connect · or tell your assistant: “Set up Threadpacket so I can send files to my wife's assistant. Read https://threadpacket.com/llms.txt.”

## What travels

- **Your notes and the files.** The brief says what you decided and what is left to do. PDFs and images go with it, byte for byte. Open a packet in Packets to read the brief and see the files.
- **Their own assistant.** Your partner can use ChatGPT while you use Claude. Each person signs in with their own username.
- **Storage, not AI.** Threadpacket keeps the brief and files and deletes them after 7 days by default. It makes no model calls.

## What people send

- **Family and household:** your partner finishes the paperwork. Sort out the details in Claude, then send your partner the notes and the PDFs. They finish in ChatGPT.
- **Small teams:** a teammate starts with your decisions, diagrams and the reasons behind them.
- **A second perspective:** another assistant reviews the same design and files.
- **Across computers:** continue on another computer, in another assistant.

## Questions

### How do I send files and instructions to someone else's AI assistant?

Connect Threadpacket in your assistant and in theirs, both in the same team. Then say “send a packet to anna with the PDFs”. Your assistant writes a brief and sends it with the files; she says “continue the packet from joe” in her assistant.

### Do we need the same assistant?

No. One person can use Claude and the other ChatGPT. Codex, Claude Code and Hermes work too. Each person keeps their own assistant and account.

### What does it cost?

Nothing. The hosted service is free and Threadpacket has no paid tier. Threadpacket makes no AI calls, so there is no token bill and no API key.

### Who can see what I send?

Only the person you send it to, and you. Threadpacket stores the brief and files as they were sent and deletes them after 7 days by default. You can revoke a packet sooner. Details: [privacy](/privacy).

### Can my assistant set it up for me?

Mostly. You add Threadpacket to your assistant once and approve the sign-in; your assistant can walk you through it from [threadpacket.com/llms.txt](https://threadpacket.com/llms.txt). After that, inviting your partner and sending packets are things you ask for in the chat.

### Can we run it on our own server?

Yes. Threadpacket is open source (MIT). A team can run it on its own Cloudflare account, on the free plan, so its packets never leave that account.

## A private server for your team

A team that wants its packets on its own infrastructure runs Threadpacket on its own Cloudflare account: one Worker, a D1 database and a KV file store, on Cloudflare's free plan with no card. Only the team's members can sign in, and nothing leaves that account. A coding assistant can do the install: “Deploy https://github.com/evgolsh/threadpacket to my Cloudflare account. Follow llms-install.md. My username is tim; add tom as a teammate.” Guide: https://github.com/evgolsh/threadpacket/blob/main/llms-install.md
