Your template, not a lookalike
Many tools generate decks in their own themes and then apply your colours, which falls apart the moment a colleague adds a slide. A corporate template is more than colours: slide masters and layouts, placeholders, theme fonts, and a theme colour set of twelve slots, two dark, two light, six accents and two hyperlink colours, which charts and shapes pick up automatically. A tool should import your .pptx or slides template and place content into your layouts rather than imitations of them. Test by generating a deck, opening it in your usual software, adding a new slide and inserting a chart.
Every number needs a source
Generated decks fail most dangerously on numbers. Charts drawn from a model's summary can misstate figures, round inconsistently or mislabel axes, and summaries of reports drop qualifiers such as forecast or unaudited. Require charts built as native, editable charts from data you supplied, never as pictures of charts, so anyone can open the data and check it. Every figure should trace back to a source file, and someone who knows the source should check the numbers before a deck leaves the team. A misquoted figure in a sales deck can become a misleading claim to a customer.
Editable output and controlled sharing
Output should be native slides with real text boxes, placeholders, speaker notes and alt text on images, not flattened pictures of slides that cannot be corrected; PDF export suits final distribution. Sharing needs as much attention as generation. Many presentation tools host decks online behind links, so check whether links can expire, require sign-in or a password, and whether shared decks can be indexed or forwarded. Viewer analytics, such as who opened which slide and for how long, help sales teams but are personal data and need the same privacy treatment as other tracking. Where decks need new imagery, Synthetic White produces on-brand images and copy under the same brand hub as the rest of the campaign.
Confidential decks and inside information
Board papers, deal materials, restructuring plans and unpublished results are routinely built as slides. For listed companies, unpublished price-sensitive information is inside information under the EU Market Abuse Regulation (Regulation (EU) No 596/2014) and its UK equivalent, which means controlling who has access and keeping insider lists. Pasting draft results into an unvetted tool widens that circle in ways nobody can document. Use only tools approved for confidential material, with contractual no-training and retention terms, a known processing location and admin control over accounts, and keep the most sensitive decks out of AI tools altogether until that approval exists.
