Rewriting an AI Deck After the First Round of Feedback
When you edit an AI generated presentation after feedback, the decision that matters is not which button to press. It is whether the feedback is about the argument, the structure, or the wording. Wording changes are safe to hand back to the tool. Structural changes are usually faster by hand than by prompt. Changes to the argument mean the deck's premise moved, and no amount of re-prompting will fix a deck that is now answering the wrong question. The one thing to avoid by default is regenerating the whole deck, because that discards every manual fix you already made: the template match, the corrected chart labels, the palette, the reordering you did last Thursday.
Sort the feedback before you open the tool
Three comments came back. Before touching anything, put each one in a bucket.
Wording and tone. "Too long." "Make the summary punchier." "Drop the jargon on slide four." These do not change what the deck says, only how it says it. They are the cheapest to fix and the most suitable for an AI editing pass.
Structure and emphasis. "Lead with the numbers." "Move the risks earlier." "This is three slides of background and one slide of decision, it should be the other way around." These change the shape without changing the content. They are mostly cut-and-move operations, and a human doing them directly is usually faster and always more predictable than describing them in a prompt.
The argument. "This assumes we are going ahead. We have not decided." "Where is the cost?" "This is a recommendation and I asked for options." These are not editing problems. The deck was built on a premise that has changed, and the honest response is to rewrite the outline before touching slides at all.
Most people treat all three the same way, re-prompt, and get a deck that is differently wrong. The sort takes two minutes and it decides everything that follows.
What a full regeneration actually costs you
Every product page in this category shows you the regenerate button, for the understandable reason that it is the feature they are selling. What none of them shows is the ledger on the other side.
A regenerated deck is a new deck. Anything you did by hand to the previous one is not in it unless the tool is applying a saved theme or a stored brand setting. In practice that means:
- Template work is gone. If you spent time on making the deck match the company template, a fresh generation starts from the tool's layout again.
- Palette and font corrections are gone, unless they were saved at the account or theme level rather than fixed slide by slide. This is the difference between a per-deck fix and a stored setting, which is the practical point of handling brand colors and fonts properly once.
- Chart corrections are gone, and worse, silently: the new chart is drawn from scratch, so a mislabeled axis you fixed may or may not come back, and you now have to re-check something you thought was done.
- Your own edits are gone. The sentence you rewrote because it was technically wrong, the number you corrected, the slide you deleted because it was repetitive.
- The reviewer's mental model resets. A manager who reviewed a deck and asked for three changes expects to see that deck with three changes, not a different deck. Handing back something structurally unfamiliar tends to produce a second, longer round of feedback.
None of that means never regenerate. It means regeneration is the expensive option, not the default one, and it should be a decision rather than a reflex.
What editing in place can do, per the documentation
The useful middle path is editing the deck you have, either by hand or with the tool's own editing features. The capabilities differ by product, so here are two examples from the vendors' own documentation rather than from a roundup.
Gamma's help center describes an agent that can "make edits across all slides at once for consistent updates" as well as editing individual slides, and lists spelling, grammar and readability improvements, translation, summarization and custom instruction-based editing among what it will do to existing content. It also states a limit worth knowing before you rely on it: formatting such as bold and italics is supported, but "theme-level changes such as fonts can only be changed if you change the entire theme". It notes that after the agent makes edits, you can refine them manually (Gamma Help Center, checked 2026-09-07).
Plus AI's feature documentation describes rewriting existing slide text to "condense, expand, change the tone, fix grammar, and more, in any language", reformatting an existing slide even when it is an undifferentiated block of text, generating variants of a slide to compare, and adding one slide at a time with a chosen slide type (Plus AI, checked 2026-09-07).
The pattern across the category is consistent: slide-level and text-level editing is well supported, and it is the right tool for the wording bucket. What is not consistently supported is anything that changes the deck's identity, which is why theme and font changes tend to be all-or-nothing. Check your own tool's current documentation before assuming a behavior, since this category ships changes frequently.
The order to make changes in
Sequence matters more than technique, because each step invalidates work done in the wrong order.
- Argument first. If the premise moved, rewrite the outline in plain text before you touch a slide. A deck built on the wrong question cannot be edited into the right one.
- Structure second. Add, delete, reorder and merge slides. Do this before you polish anything, because half of what you would polish is about to be cut.
- Content third. Fix the words, the numbers and the claims. This is where an AI editing pass earns its place, one slide at a time, with you reading the result.
- Visuals fourth. Charts, images, template alignment, palette. Doing this before step 2 means formatting slides you will delete.
- Speaker notes last. Notes are generated from slide content, so they are wrong the moment a slide changes. Regenerating or rewriting speaker notes you can read aloud is the final step, not the first.
- Export last of all. If the deck has to leave the tool as a PowerPoint or Google Slides file, do that after everything else and check the result, since export is where a finished-looking deck breaks.
Handling the three kinds of feedback
"Make it shorter." Cut slides, not words, at least to begin with. Removing three slides is more visible to the reader than trimming a line from every slide, and it does not degrade the readability of what is left. When you do compress text, check that what disappeared was repetition and not evidence.
"Lead with the outcome." This is a reorder plus one new slide, and it is a hand edit. Write the new opening slide yourself, since it carries the claim the whole deck now rests on, and move the supporting material behind it.
"I do not agree with slide six." Do not rewrite slide six until you know whether the disagreement is with the wording, the data or the conclusion. If it is the data, the fix is upstream in your source, not on the slide. If it is the conclusion, ask before you rebuild, because you may be about to spend an hour producing a second version of a disagreement.
"Can we see a version for the wider team?" That is not feedback on this deck, it is a request for a second deck with different emphasis. Treat it as separate work rather than folding it into this round.
Keeping a record so round two is shorter
Two habits, both cheap.
Save a copy of the version that was reviewed, before you change anything. Some tools keep version history and some do not, so do not rely on the feature existing in yours. A duplicate file named with the date is sufficient and it means you can answer "what did I change?" precisely.
Keep a short list of the changes as you make them, in the order of the feedback you were given. When the deck goes back, that list is the covering note, and it turns a second review into a check against three specific items rather than a fresh read of thirty slides. It also catches the thing that most often causes a third round, which is a request you forgot.
When starting over is the right call
Regenerating from scratch is right in a narrow set of cases: the premise changed completely, the deck is short enough that manual fixes are not worth preserving, or the structure is so far from what is needed that you would be rebuilding most of it anyway. In those cases, generate from a better input rather than a better prompt, since a deck built from a document you control is more predictable than one built from a topic line.
Everything else is an edit. The general review pass that any AI-built deck needs before it is presentable is the same either way, and it is described in building a work deck with AI: the tool produces a draft, and the judgment about what the audience needs stays with you, in the first round and in every round after it.
FAQ
Should I regenerate the whole deck or edit individual slides after feedback?
Edit individual slides in almost all cases. A full regeneration discards manual template work, palette fixes, chart corrections and your own edits, and it hands your reviewer an unfamiliar deck. Regenerate only when the deck's premise has changed or the structure needs rebuilding anyway.
Can AI tools edit a deck they did not generate?
Many can operate on an existing deck, and the documented capabilities usually cover text rewriting, reformatting a slide and applying consistent changes. Support varies by product and changes often, so check the vendor's current documentation for your tool rather than assuming.
Will editing with AI change my formatting?
It can. Text-level edits generally respect the existing layout, but changes that touch the theme are often all-or-nothing: one vendor documents that fonts can only be changed by changing the entire theme. Make a copy before any deck-wide edit.
What if the feedback is that the deck is wrong, not badly written?
Stop editing and go back to the outline. A deck answering the wrong question cannot be fixed at the slide level, and rewriting slides first means doing the work twice.
How do I stop the second round being as long as the first?
Save the reviewed version, keep a numbered list of the changes you made against the feedback you were given, and send that list with the deck. Reviewers check a short list faster than they re-read a deck.
