Keep the screenshot and current post separate
Use your own post, a public organizational announcement or another source you are authorized to review. Save the actual post link and note the sentence you want to quote. A screenshot is a separate observation whose capture time may be unknown.
If you have not found the original yet, use the X phrase-and-date search guide. This page starts after you have a candidate post and need to resolve a wording difference.
Inspect the available edit history
X documents an edited icon and label for a changed post, with previously published versions available through the post. Its instructions also identify a Last edited button for viewing history. Source
Open that history when it is available and compare the sentence in context. Record the version and displayed time that you actually inspected. Do not invent a revision time from the timestamp in a screenshot filename.
X also distinguishes Edit from Undo: editing changes a published post, while Undo is a pre-publication action. Its help lists post types that cannot be edited. Source Do not assume that every post has a recoverable public version history.
Describe the change precisely
| Difference you can see | What the note should preserve | What remains unproven |
|---|---|---|
| A word was corrected | Earlier and later wording | The author’s reason |
| A date or qualification changed | The full affected sentence | Which claim was true in practice |
| Attached media differs | Which version you inspected | The meaning of an inaccessible attachment |
| Screenshot and history do not align | Both observations and missing context | That either was deliberately deceptive |
An illustrative announcement may change a meeting date while keeping the rest of its wording. Quoting the earlier date as the current plan would misrepresent the version you just checked. Conversely, replacing an old quote silently can hide what an earlier article actually referenced.
Finish with a version-aware citation
Keep the post address, supporting wording, visible version information and your access date together. State whether you are describing an earlier publication or the current visible text. If history cannot be accessed, leave the discrepancy unresolved rather than reconstructing an edit.
For text copied from a screenshot, revisit the OCR comparison checklist so a recognition error is not mistaken for a revision. For an AI summary, use the source-review checklist to keep each claim tied to its inspected version.
These are X’s native reading controls. The App overview does not promise access to deleted posts or a complete edit archive.
