Install and use the extension

Add to Chrome

  1. Install DGU Chat Cleaner from its official Chrome Web Store listing, in Chrome on desktop.
  2. Open chatgpt.com and sign in to your account.
  3. Click the DGU Chat Cleaner icon in the Chrome toolbar to open the panel. If it is not visible, open the extensions menu (the puzzle piece icon) and pin it.
  4. Tick the conversations to process: one by one, with Shift-click for a range, or with “Select all” for the loaded conversations.
  5. Choose “Archive selection” or “Delete selection”, then review the list of titles shown.
  6. Confirm, then keep the tab open without interacting with ChatGPT until the summary appears.

Deletion is permanent. To remove a conversation from your visible history without losing it, choose archive.

The panel will not open

Open chatgpt.com, reload the page, then click the DGU Chat Cleaner icon. You may need to reload ChatGPT after updating the extension.

Change the panel language

Choose Automatic, English or Français in the panel’s language selector. Automatic follows the browser interface language: French when it is French, English otherwise. Your choice is saved locally on this device.

Reading the summary

The summary lists every conversation in the batch: deleted or archived, uncertain, failed, not attempted after a stop, or remaining. Each conversation that did not succeed shows its reason and a link to open it in ChatGPT. An “uncertain” conversation may have been processed: check it, or use “Retry uncertain conversations” so that ChatGPT’s answer settles it. After a batch, the ChatGPT sidebar may still show processed conversations: reload the page.

Processing stopped

If the batch stops before the end (lost connection, requests limited by ChatGPT, closed tab), it is kept on your device, then erased on your next visit to ChatGPT once seven days have passed. Reopen the panel on chatgpt.com: it announces the interrupted batch. “View the batch” shows its summary, then “Resume the batch” continues with the remaining conversations, without confirming again; “Drop the batch” erases the saved batch without undoing what was already done. While an interrupted batch has been neither resumed nor dropped, no other batch can be started. The extension cannot restore a conversation that has already been deleted.

Some conversations are missing from the selection

Only chats loaded in the sidebar are available. Scroll that list before selecting. Archives are not scanned automatically.

Dates and ignored chats

Preselection is a Pro feature, available during the free 30-day trial or with a license. It uses known last activity, including messages and renaming. Only loaded, non-ignored chats with reliable dates are eligible. Adding chats to the ignored list is also a Pro feature; removing them stays available without Pro. Choose 30, 90, 180 or 365 days, or an exclusive local date, then apply to replace the selection. Deselected chats are never automatically selected again. Reload ChatGPT if dates are missing. Removing an exclusion does not select the chat. Storage failures block actions.

Before starting a batch

Check the titles, keep the tab open and wait for completion without interacting with ChatGPT. Avoid making changes to the same account from another tab or device during processing.

Before you confirm, the panel shows how the batch will be processed. With direct access, the extension sends each request to ChatGPT itself. If direct access is unavailable, it says so and drives the ChatGPT menus instead, more slowly. If ChatGPT limits requests or does not answer, nothing starts: use “Check again” a little later.
