This book is mostly…
Aveu reads through your conversations with AI and picks the letters that will make your book. It all happens in this browser: nothing is uploaded, nothing is kept once you close the page.

Where do your letters come from?
Drop in the export of your conversations: it's read right here, in this browser. You could even turn off your Wi-Fi.

Reading your export…
ClaudeAn email with a link, often within minutes
- Open claude.ai in a web browser (computer or phone, not the app), then go to Settings → Privacy.
- Tap Export data.
- You'll get an email with a link; download the conversations file (conversations-000.zip, plus -001, -002… if there are several). Each link works only once.
- Drop it here as is. Several parts? Drop them in together.
The links work only once: download the file before you close the page. If you drop the list itself (a “manifest-….json” file), Aveu shows you what to download.
Technical details
Each zip holds a JSON file: a list of conversations (“chat_messages”). Aveu also accepts one conversation per file, or a { conversations: [...] } object. Only text blocks are kept: Claude's thinking, tools and attached files are ignored.
ChatGPTAn email, anywhere from a few minutes to 7 days
- In ChatGPT, open Settings → Data controls.
- Tap Export data, then confirm.
- You'll get an email with a download link. It only works for 24 hours: download the zip as soon as it arrives.
- Drop the zip here as is (or the conversations.json file, if it's already unzipped).
It often takes less than an hour, but OpenAI says it can take up to 7 days. In the meantime, or .
Technical details
The zip contains conversations.json (each conversation is a tree of messages: Aveu keeps the version shown on screen), plus other files (images, chat.html) that Aveu never opens.
Paste a conversationFrom ChatGPT, Claude, Gemini, Copilot…
Open the conversation, select all of it (or use each message's “Copy” button), then paste it here.
How Aveu tells your words from the replies
1. It looks for lines that say who's speaking: “You said:”, “ChatGPT said:”, “Claude:”, “Me:”, “Gemini:”… 2. Otherwise, it splits at “---” lines (or at two blank lines): the first block is yours, the next is the reply, and so on. 3. With no markers at all, everything becomes a single letter, in your name. The date isn't in the copied text: it's today's, so change it if you like.
