Start with the conversation you already have
What Brandon Thinks, made by GumGum, accepts WhatsApp and iMessage as well as Instagram and Messenger. Its FAQ says those last two sources use a screen recording of a chat with one person. That is a practical distinction when your exchanges live outside WhatsApp.
Michel starts with a WhatsApp export. Upload the text file, choose participants and a language, then see the preview. Our guide follows the official Android, iPhone and Web export paths. Keep your conversation; give it a different shape.
Doing it yourself with a general-purpose AI
With ChatGPT or another general-purpose assistant, you can paste an export excerpt and write a prompt. You choose what to send, explain the context and ask for the response you want. This route takes more preparation and adjustments from you.
The result of that approach is an answer to your prompt, rather than an already laid-out report. If you want pages, visual portraits or a document ready to share, formatting becomes a separate task. It suits people who want to build their own presentation.
Which should you choose?
Consider Brandon if you want to analyse iMessage, Instagram or Messenger, or explore a couple’s relationship. Its site also presents uses for friends and families. Follow-up questions offered after a report let you continue around the same chat.
Choose Michel if you want an illustrated report in French for a WhatsApp group at a small price: €3.99 for the full report. The free preview lets you see the beginning before buying. Portraits, cards and a PDF then give your group different ways to share the memory.
For a birthday, an end-of-year gathering or flatmates moving apart, ask what you would like to keep: a reading of a relationship, a group chronicle or a text you shape yourself. These are possible uses, not testimonials. Your own conversation is the best starting point.
