Use a duplicate project, make a documented mix of ordinary and AI-assisted edits, confirm that they are initially undoable, then close and reopen the project to see which individual steps remain available.
What the Test Needs to Establish
The test should answer a narrow question: after closing and reopening a project, can you still reverse completed edits individually and in the expected order? Undo normally depends on commands recorded in a history buffer, but some actions may never enter that history. A history can also have a limit; Microsoft, for example, documents a default maximum of 100 undoable actions in Office and notes that certain actions cannot be undone.
Do not treat restoration of an earlier saved file as proof that undo history survived. Session-level Undo reverses recorded commands, while saved-version recovery restores a prior file state. Both may help recover work, but they demonstrate different capabilities.
Set Up a Controlled Undo-History Test
Work on a duplicate, noncritical project so the experiment does not endanger production material. Before editing, record the application version, project name, and test time. Then create a short numbered sequence that is easy to recognize, such as:
- Make one ordinary visual change.
- Make a second, clearly different ordinary change.
- Apply one AI-assisted change that affects identifiable content.
- Make one final ordinary change.
Immediately after each completed operation, check whether Undo can reverse it, then use Redo if available to restore the test sequence. Record any operation that is missing from the active-session history. This baseline matters because an action that was never recorded cannot demonstrate persistence after reopening. AI-assisted changes deserve an explicit check because one command may affect multiple elements; Lega, for example, describes AI-generated layout changes as reversible commands in its own session history, but that behavior cannot be generalized to other editors.
Close, Reopen, and Check Every Editing Context
Save the duplicate project using the editor’s normal project-saving process, close it, and reopen the same project. Before making any new change, inspect the Undo control and any visible history panel. Attempt to reverse the documented edits one at a time, noting which step becomes available, its order, and whether the AI-assisted operation reverses as a complete operation.
Check every relevant editing context rather than relying on one Undo button. IMG.LY documents that its CE.SDK can use multiple independent history stacks for different contexts, showing why one history control may not represent every context in an editing system. If the tested editor has separate modes, canvases, documents, or panels, revisit each one and record its result separately.
If Undo is unavailable but an earlier saved version can be restored, classify that outcome as saved-version recovery—not persistent step-by-step undo. Likewise, an enabled Undo control alone is insufficient evidence unless it reverses the same pre-close operations in the expected order.
Conclusion
Classify the outcome as one of four results: persistent step-by-step undo, session-only undo, partial history, or saved-version recovery only. Keep a brief record of the tested software version, actions, contexts, and observed results so the conclusion remains tied to that specific test.
The supplied evidence does not confirm that any named AI image editor preserves its undo stack after a project is closed and reopened. Documentation about session histories or reversible commands does not establish reopen persistence. Run this test on a duplicate project now, and repeat it after material software changes before depending on undo history in an important workflow.
Disclosures and limitations
- This article was prepared with AI assistance from the supplied research package; product-specific reopen persistence was not established by those sources.
- No product recommendation or affiliate relationship is presented. Readers should verify behavior in a duplicate project before relying on it.
