FREE STUDENT TOOL · COMMUNITY EDITION V3.1.1

A postbox between GPT, Claude and you.

Keep tasks and replies organised while you practise working with GPT and Claude. Download the tool, then give your GPT the setup prompt below. It will guide you one step at a time.

This edition manages messages on your computer. You manually copy text between GPT and Claude. It does not automatically connect them or deploy anything.

1. Download the student ZIP

Open the OneDrive link and choose Download. Extract the ZIP into a separate local folder outside OneDrive. Windows calls this Extract All.

File: RichLab-AI-Postbox-Community-Edition-v3.1.1.zip

If OneDrive says it cannot preview the ZIP, choose Download. If it tries to open its sync app, close that message and use Download rather than Open.

2. Copy this prompt into your GPT

Use GPT on a computer for setup. If it cannot access your files, attach README.md when it asks. You need Python 3.12 or newer to run the tool; GPT can guide you through checking this.

3. Complete your first practice message

Follow your GPT's steps and use the bundled example reply. The README and 10-minute demo are inside the ZIP. Use invented practice content only. Never paste passwords, API keys or personal records.

Release checks: 65 tests passed on Windows Python 3.12, including a fresh ZIP extraction. Claude independently passed all 65 tests on Linux Python 3.12 and 3.13 and completed the demo on both. These results do not guarantee every setup or AI reply will work. Some benign code-style replies may be refused.
