# Review & Edit Before Inserting

After generation, Twistly shows every slide's content for review. **These are your real slides** — any edit you make here is exactly what appears in PowerPoint.

## What you can do

* **Edit all text** — titles and body content, with formatting: bold, italic, underline, strikethrough, and links all carry into the final deck. Titles are optional.
* **Reorder slides** by dragging. The cover slide stays first.
* **Add a slide** — appends an empty slide. At your plan's slide limit, the add button becomes an upgrade prompt instead.
* **Delete a slide** — hover over it and use the trash icon (the last remaining slide can't be deleted). The slide is removed at once, and an **Undo** button stays on screen for 5 seconds.
* **Edit tables** — click into a table for row and column controls. You can also **paste a table** from Excel, Word, or Google Sheets and it stays a real, editable PowerPoint table.
* **Edit charts and diagrams** — change their values and points, add new ones, or swap them for another kind. See below.

## Charts and diagrams

Charts and diagrams are editable in the review step, so you can fix the numbers and points before the deck is built.

* **Chart values** — each chart lists one row per data point, with its label and its value. Edit either one, add a row with **Add column** (bar chart), **Add slice** (pie chart) or **Add data point**, or remove a row with its cross (with the same 5-second **Undo**). A value that isn't a number goes back to what was there instead of becoming 0.
* **Pie charts must total 100%.** When you change a slice, the slices you haven't typed are adjusted so the total stays at 100%. If the total still isn't 100% — for example, after adding a slice — an error appears and **Continue** is blocked until you fix it. Twistly scrolls to that slide and puts your cursor in the field to correct.
* **Diagram points** — every point of an agenda, summary, timeline, quote, structure or **Key figures** diagram is a text field, including empty points left for you to fill. Add a point with **Add item** (**Add step** on a timeline), or press Enter in the last field. On a structure diagram, Tab and Shift+Tab move a point one level in or out. To remove a point, use its cross, or clear its text and press Delete or Backspace.
* **Add a visual** — hover over any slide except the cover and click the label that shows its visuals (**Text only**, the visual's name, or "*N* visuals"). Choose **Bar chart**, **Pie chart**, **Radial chart**, or a diagram: **Agenda**, **Summary**, **Timeline**, **Quote**, **Structure**, **Key figures**. The new visual is added beside the ones already on the slide.
* **Replace a visual** — click that visual's own picture and pick another kind.
* **Remove visuals** — the trash icon on a visual's picture deletes that one visual (with **Undo**). **Remove all visuals** (**Text only** when the slide has one) clears them all.

| Diagrams per slide                                                    | 2     |

## Limitations

* **Generated slides keep charts and diagrams to a minimum.** Add more yourself, up to the limits above.
* **Agenda, summary, timeline and quote diagrams take the whole slide when they're on their own.** Nothing can be added beside them, and only the slide title stays editable — a lone quote has no title at all. You can still switch the diagram to another kind.
* **Empty labels and empty visuals don't block you.** A note tells you, and a chart or diagram left completely empty is left out of the slide.
* **On your own custom templates, charts are shown as read-only previews** and can't be deleted or swapped here. Edit them in PowerPoint after inserting.
* **On your own custom templates, you can't add slides in the review step** — the add button isn't shown. Editing text, reordering and deleting still work. To add a slide, insert the deck first and use [Add a Slide](/edit-and-improve-slides/add-a-slide.md).
* There's no "insert table" button — tables come from generation or from pasting.
* Very wide or long pasted tables (over \~6 columns or 10 rows) may render with small text; nothing is cut, but consider splitting them.

**Going back discards your generated slides.** Navigating back from the review step to change the template or content cancels the generation — you'll need to generate again. Finish your review and insert first; you can always edit afterwards.
