You need a presentation, but the source material lives in three documents, some notes and your head. Designing slides isn't the first task. First, decide what the audience needs to understand and which decision you want them to make.
On 16 September 2026, Anthropic announced the integration of Claude chat and Cowork, alongside Claude Docs, Slides and design capabilities in chat. The new experience is rolling out to Pro and Max users; document, slide and design features are in beta on paid plans. Source: Claude product blog.
Opus 5.5 followed on 22 September and Sonnet 5.5 on 28 September. Anthropic describes Sonnet as a faster, more affordable complement to Opus. That is the supplier's description, not an assessment of your particular task. Source: Claude release notes.
Include the decision context
A useful brief might be: “Turn these notes into six slides. The audience needs to decide whether to continue the pilot. Show the results so far, unresolved problems and two ways forward. Mark missing figures as missing.”
Review the slide headings before designing anything. If they don't tell a clear story, the structure needs work. Only then add design, charts and speaker notes.
In an example process, the project manager checks the claims, the finance lead checks budget lines and the presenter checks whether the material suits the audience. AI can bring the preparation together, but doesn't automatically know which internal agreements are final.
Check the exported file too
Open the exported presentation before sending it. Check table readability, accented characters and layout. Something that looks good in chat may need adjustment in the downloaded file.
AILithe helps connect this method to your existing templates. Clear inputs, structure and checks make the benefit repeatable for the next report.
