Quick Setup Guide

You're setting up two separate things:

Truffle Journal (iOS app)

This is where you actually write and manage your journal.

Truffle Journal (ChatGPT app)

This is the ChatGPT-side connection that lets ChatGPT save entries, list your entries, and search what you've written—only when you ask for it.

During beta, the iOS app is delivered via TestFlight, and the ChatGPT app is added via Developer mode.

A

Install Truffle Journal on iOS (via TestFlight)

1

Install TestFlight from the App Store.

2

Open our TestFlight public link on your iPhone (link provided after joining beta).

3

Tap Accept → Install.

That's it—Truffle Journal will appear on your Home Screen like a normal app.

Good to know (beta life):

  • • Updates arrive through TestFlight (you'll see an Update button when available)
  • • TestFlight builds have a time window; if a build expires, installing the latest build fixes it

Use Truffle Journal when the user wants to save something to their journal, review past entries, or search for something they wrote. If the user says "add to Truffle Journal" (or asks to log/save a thought), create a new entry using add_memory. If they ask to see their entries—optionally by date or other filters—use list_memories. If they ask to find a specific past entry or topic, use search_memory.

Frequently Asked Questions

Private by Design

Your journal is stored in a managed Postgres database with encryption in transit (TLS) and encryption at rest (AES-256)—the same cryptographic standards commonly used across major platforms and cloud infrastructure.
