# Add a Slide

Add a single slide to your presentation — the new slide is inserted **right after the slide you currently have selected** (not at the end). Available on all paid plans.

## Ways to fill the slide

* **AI-generated** — pick a template and layout (or **AI Decides**), describe what the slide should say, and the AI writes it. If your deck already has a few titled slides, Twistly suggests topic ideas based on them.
* **Attach a file** — base the slide on a document: `.pdf`, `.pptx`, `.docx`, `.txt`, or `.html`, up to **5 MB**.
* **Pre-designed samples** — ready-made slides such as contacts, team, and thank-you, inserted instantly.
* **Blank layout** — an empty slide in the chosen layout, no AI involved.

## Good to know

* Add a Slide requires a paid plan (Starter, Pro, or Team). On the Free plan, opening it shows an upgrade prompt — see [Plans](/plans-billing-and-team/plans.md).
* With a [custom template](/custom-templates-pro-and-team/using-and-managing-templates.md) (Pro & Team), the AI fills **exactly the layout you chose** — it won't switch to a different one.
* In a presentation that already has slides, a slide must be selected in PowerPoint for insertion to work. In an empty presentation, the new slide simply becomes the first slide.
* The new slide is selected automatically after inserting, so you land right on it.
