A message that has been changed carries a small "edited" mark. Opening the message's own details shows when the last change was made, down to the minute.
It is a record that something happened. It is not a record of what happened, and the difference is where every argument about it starts.
What you will be able to do
- check_circle Find when a message was last changed.
- check_circle Say what the mark proves and what it does not.
- check_circle Handle a reply whose question was edited.
- check_circle Keep a record when one actually matters.
The edit time sits with the message's own details, not on the bubble itself.
history_toggle_off An event, not a version
Software that tracks changes usually keeps the old text so you can see what moved. This does not. There is one message, it holds its current contents, and beside it sits the time it was last altered. The previous wording is gone for everybody, the author included.
So the mark is a modest thing that people routinely over-read. It says a change was made at a time. It does not say whether a comma was fixed or the meaning was reversed, and no amount of tapping will reveal that.
It is still worth having. Without it, a message could be quietly rewritten and a reader would have no reason to doubt what is in front of them. With it, at least the fact of a change is visible, and a conversation where somebody is disputing what was said can be conducted honestly.
The related detail in the same menu is who has read the message, in groups where that is available and for a limited period afterwards. That is a separate thing with its own pitfalls and is not what the edit mark is about.
You open a message's details and see that it was edited yesterday at 14:20. What do you now know?
There is no stored history. You get the time of the last change and nothing else — not the earlier wording, not the number of edits, not which part moved.
Somebody edited a message before you ever opened the chat. Do you see the "edited" mark?
The mark belongs to the message, not to your reading of it. You will see it even though, for you, there was only ever one version — which is why a marked message is not by itself a reason for suspicion.
You asked a question, somebody replied to it, and you then edit your question. What happens to their reply?
The reply points at the message, not at its contents, so editing changes what somebody appears to have been answering. This is the one genuinely harmful edit: if a reply already exists, add a correction as a new message instead.

fact_check When you need an actual record
For anything that might be disputed — a price, a deadline, an instruction somebody will act on — the edit mark is not a substitute for a record. It cannot show what changed, and in a private chat either person can delete a message entirely, mark and all.
If it matters, quote the agreement back in a new message so the wording exists twice, or export the conversation. Both are ordinary things to do and neither requires anybody's cooperation.
Channels deserve a separate thought, because the time limit that applies in a conversation does not apply there: an admin can edit a post years later, and the archive readers rely on can change under them with only a small mark to show for it. That is usually a good thing — a corrected post is better than a wrong one — but it means a screenshot is the only way to hold a channel to what it said last month.
settings Reading and leaving the mark
- Open the message's details The edit time is there, not on the bubble.
- Read it as an event A change happened, nothing more.
- Do not treat a mark as suspicion Most edits are typos.
- Never edit a message that already has replies Add a correction instead.
- Say what you changed If anybody acted on the old version.
- Keep a real record for anything disputable Quote it or export it.
This page is one mark on one message. The curriculum step is proper record-keeping in a group: what the admin log captures, how long it keeps it, and the difference between a trace that exists and a trace anybody can check.
