A slide pool is a .pptx you upload so its slides become a searchable library of reusable layouts. Upload your approved deck once, and every slide in it is something you or the agent can find and reuse. A pool is not a master or a template deck. A master governs the theme of a whole deck; a pool is a shelf of finished slides you pull one at a time. Uploading a pool changes nothing about the deck you have open.

Your pools

Assets → Layouts opens on your pools, each with a preview and its slide count. Hover a pool to rename or delete it; deleting takes its slides with it.

Uploading takes one .pptx.

Upload takes a .pptx. Processing runs in the background, so you can close the panel and keep working.

While it processes, Pretty renders a preview of every slide and writes its Structure and Content descriptions.

Browsing and inserting

Open a pool to see its slides, searchable with Search slides…. Back returns to the pool list.

Click a slide to insert it. Hovering exposes Add to chat and Edit details.

Add to chat hands the layout to the agent for your next message (“fill this layout with the numbers from the attached file”). Edit details opens the fields below. Inside a pool, a toggle in the toolbar switches between two ways of bringing a slide across: Match deck theme“remaps the slide onto your deck’s master (adapts to the current theme)” — and Keep original look“brings the source master along (identical to the pool preview; adds a master to your deck)”.
Keep original look adds the source master to your deck. Do it for a handful of slides from different pools and you end up with several masters in one file, which makes later theme changes messy. Prefer Match deck theme unless the slide has to be pixel-identical.
Your workspace also has a default insert mode that applies when the agent inserts a pool slide on its own. Out of the box it is AUTO, which reuses a same-named destination layout when one exists and otherwise keeps the source. The agent finds a slide by what its descriptions say. Edit details on a slide card opens three fields: Structure for the shape of the slide, Content for its subject and audience, and Editor notes for house rules the agent should follow.

Structure and Content are written for you during upload. Both are yours to rewrite, and edits save as you type.

Until a slide has been analyzed the first two read ”…— not analyzed yet.” Editor notes always starts empty.

How the agent uses them

The slidepool_search tool ranks the pool’s slides by their Structure and Content text, then re-ranks the top candidates by looking at their thumbnails as a 2×2 grid, and returns the four best. It searches with a full phrase rather than a keyword (“a quarterly revenue bar chart for execs”), so your descriptions should read like phrases too.
Instead of choosing for you, the agent can hand the candidates back. The step is titled “Choose a slide layout” and carries a note field: “Optional: note for the AI (e.g. focus on Q3 results, drop the 3rd column…)”. Pick one, say how you want it adapted, and the agent builds on it.

Writing descriptions that get found

Describe the layout and its job, not the sample numbers that happen to be on it. The descriptions in the screenshot above are the shape to copy; “Slide with boxes and text” and “Financials” are what to avoid.
  • Write phrases, not keyword lists. The ranking compares meaning.
  • Put the layout in Structure and the subject in Content. Splitting them keeps both searchable on their own.
  • Name the audience if the slide has one: “for a board”, “for a client kickoff”.
  • Put constraints in Editor notes, not in the description.
If the agent keeps reaching for the wrong slide, fix Structure and Content on the slides it should have picked. That does more than rewording your prompt, and it fixes it for everyone.
