Click on your profile avatar (top right) → Settings.
Under Data or Privacy, find Export data (or Download conversations).
Request the export – you'll receive a conversations.json file (may be large, up to 100+ MB).
Load the file into the viewer
Click the 📂 Load conversations.json button in the top bar.
Select your downloaded conversations.json file.
The viewer will parse it (takes a few seconds for large files) and show all conversations.
Navigate and search
Conversation list – click any conversation to view messages.
Global search – search across all conversation titles and content (top bar).
In‑chat search – type in the “🔎 Case‑sensitive (min 3)” box to highlight text inside the current conversation.
Message navigation – use the Top / Prev / Next / Bottom buttons or arrow keys (↑ ↓).
Copy message – click “📋 Copy Msg” to copy the currently visible message. “📚 Copy All” copies the whole conversation.
Bookmarkable URLs – the URL updates with ?conversation=5&message=12 so you can share or reload exact positions.
Editing – hover a message and click ✏️ Edit to modify its text, or 🗑 Delete to remove it. Hover a conversation in the left list to rename (✏️) or delete (🗑) it.
Saving – after editing, use 💾 Save (Ctrl+S) to write back to the same file, or 💾 Save As (Ctrl+Shift+S) to save to a new file. A ● modified badge in the top bar shows unsaved changes.
💡 Tip: The viewer automatically remembers your last loaded file (via IndexedDB). After you load a file once, it will reload on next visit – no need to select it again.
🔧 Scrolling offset – If the message labels are hidden behind the top bar, you can adjust SCROLL_OFFSET_PX at the top of the HTML file (currently 128px).
✅ That's it! Enjoy exploring your DeepSeek chat history.
