Start by asking Napkin to make specific changes: refine the content, swap layouts, adjust the tone, or regenerate individual slides. If the overall direction feels off, it may help to go back to the outline stage and adjust the structure before regenerating. The more specific your instructions, the more accurate the output.

Make sure your file is a supported type: PDF, Word (DOCX), PowerPoint (PPTX), Excel (XLSX), CSV, text, Markdown, HTML, RTF, or a JPG, PNG, or WEBP picture. Each file can be up to 20 MB, and you can attach 10 files per message. If it contains unusual formatting, the import may not work as expected.

If a file fails to upload, Send is disabled and your text stays in the box. Remove the failed file, then attach it again or send without it.

While a presentation is being built, the chat shows a status such as "Creating slide 2 of 4". If it adds "Taking longer than usual", that alone is not a failure, so give it a little more time. Try refreshing the page. Your progress should be saved. If the problem persists, try starting a new presentation. If it keeps happening, reach out to our support team at [email protected].

Make sure you're opening it in an up-to-date version of PowerPoint. If specific elements look off, try re-exporting the file. If the issue persists, contact our support team at [email protected] with details about what doesn't look right.

This can happen after making manual edits to individual slides once a brand style or effect has already been applied. Re-apply your brand style or effect across the full deck to bring everything back in sync.

Check that the style was applied to the whole deck, not just individual slides. If you've set up a custom brand with your own colors and fonts, make sure it's saved correctly before applying it. If it's still off, try re-applying from Brand Studio.
