It is not gone. Editing or resending one of your messages in the UNIfy chat clears that message and the reply underneath it from the view on your screen, so the new answer arrives in a clean space rather than below a stale one. The original exchange is still stored on the conversation. Reopen the chat from your chat list and the saved transcript comes back, original question and original answer included.
What each of the two actions does
Edit takes the message out of the view along with the reply beneath it, and puts your original wording back in the message box for you to change. Nothing is sent until you press Send. If you change your mind and navigate away without sending, nothing was lost.
Resend does the same removal and sends the identical message straight away, without giving you the box. Use it when the answer was wrong or the assistant misread you, not when you want to reword.
Both actions remove exactly two things: your message, and the single assistant reply directly after it. If your message was the last one in the chat and nothing had answered yet, only your message goes.
What the removal does not touch
- Actions that already ran. If the assistant created a project, generated an image or followed someone in the reply you just cleared, that work happened and is still real. Clearing the reply from the view does not undo it.
- Credits already spent. An image generated in the removed reply drew on your free daily allowance or your credits when it ran, and editing the message afterwards does not give any of it back.
- The stored conversation. The transcript on the server keeps the whole exchange.
That last point is worth being clear about, because people reach for Edit as a way of taking something back. It is not one. If you posted something you would rather was not on the record, editing the message does not remove it from the stored session, and deleting the chat hides it from your list rather than erasing it.
What the assistant sees after an edit
The assistant reads a window of recent exchanges rather than the whole conversation, so an edited message usually reads as a fresh question and gets a fresh answer rather than a correction of the old one. If the point of the edit was to fix one detail, say what changed. "Same request, but for the Rome project" beats resending a whole paragraph with one word different. See the assistant reads the last ten exchanges of a chat.
