Receipts

Receipts is a macOS app that analyzes a user's iMessage history to tell their personal story. It generates summary statistics and detail about specific relationships or group chats from text message data already on the user's device. It is built for anyone who wants to explore patterns in their own text conversations, using AI to learn from and simulate them.

A user downloads Receipts for an Apple Silicon or Apple Intel Mac and lets it read the iMessage database already stored locally. If messages from an iPhone are missing, the user can sync them first in the Messages app's settings. Receipts then processes the data on-device, apart from the parts sent to AI features.

Receipts can produce holistic summary statistics from a user's texts and surface details about specific online relationships and groups. Its AI features learn from a user's conversations and can simulate interactions with others, using ChatGPT on the backend only for the parts of the analysis that require it.

Receipts is currently only supported on macOS, with separate downloads for Apple Silicon and Apple Intel machines. All data stays stored locally on the device except for the portions sent to the AI backend, and nothing is sent anywhere if the AI features are not used.

Use cases

• Understanding patterns across a specific relationship or group chat
• Simulating conversations with another person based on text history
