Enable ChatGPT connector to edit existing Gamma files and create templates from imported PPTX decks

Pierre-jean Cherret

Feedback / feature request
I use Gamma with ChatGPT for professional legal / regulatory presentation workflows where content non-regression is critical. The current connector is useful for creating new Gamma files, but it does not support the most important workflow: importing an existing PPTX donor deck, turning it into a reusable Gamma template, and then asking ChatGPT to generate or update a specific slide while preserving locked content.
Current limitations:
ChatGPT can create a new Gamma, but cannot edit or update an existing Gamma by URL or ID.
An imported PPTX cannot be converted into a Gamma template from ChatGPT.
generate_from_template
 only works with existing Gamma templates, not regular Gammas or imported PPTX donor decks.
The connector wording is confusing because users expect “from template” to work from an imported presentation.
There is no strict preservation mode for regulated/legal decks: no rewrite, no deletion, no summarisation, no added claims.
Speaker notes are not reliably preserved or controlled from ChatGPT.
There is no slide-by-slide update workflow, e.g. “replace Slide 9 using this locked content and this exact visual style.”
Requested features:
* Add edit_gamma
 / update_gamma
 by Gamma URL or ID.
* Add create_template_from_gamma
 and create_template_from_pptx
.
* Allow imported PPTX decks to become connector-usable templates.
* Add a strict-copy mode: no rewrite, no deletion, no summarisation, preserve speaker notes.
* Add slide-level operations: create, replace, update or restyle one specific slide.
* Allow exact image/file injection from ChatGPT with “use this exact image, uncropped”.
* Provide a non-regression report showing what was changed, removed or added.
This would make Gamma much more useful for professional consulting, legal, regulatory and board-level decks where the visual layout needs AI assistance but the content must remain source-bound and auditable.

Hey Pierre-jean Cherret, this is insanely helpful and specific, thank you. Totally get why “non-regression” and auditability are table stakes for legal and regulatory decks, and I’ll pass this whole set of asks to the team.
Quick couple questions so we can scope this the right way:
1) For the strict-copy mode, what should be considered “locked” by default: all text + speaker notes + images, or only specific slides/blocks you mark as locked?
2) For the non-regression report, what level of detail do you need: slide-level summary only, or a diff down to individual text runs / notes / image swaps?
If you have a sanitized example donor PPTX (or even just a screenshot of what “locked vs editable” should look like), that would help a ton too, but no pressure.
