# Draw on a frame

Pause the video, press **D**, and draw on the frame with the pen, a shape, an arrow, or text. revis.io saves your drawing automatically and marks the frame with a tick on the timeline. revis.io's UI calls drawings "sketches" in some places.

::: info Before you start

* **Who:** anyone who can comment on the review: Owners, Admins, Members, Project Admins, Contributors, and Reviewers. Viewers can't draw. Guests can draw when the share link allows **Annotate**, and some links ask them to confirm their email first (see [Comment, draw and set status as a guest](/sharing/what-guests-can-do)).
* **Where:** the web app.
* **You need:** a browser with WebGPU, such as current Chrome or Edge, or Safari 26 or later, with hardware acceleration on. Drawing has no fallback: if the browser has no WebGPU, the **Drawing tools** toolbar doesn't appear, and revis.io shows a short notice instead.

## Draw an arrow

1. Go to the frame you want to mark.
2. If the video is playing, press **Space** to pause it.
3. Press **D** to turn on drawing mode.
4. Choose **Arrow** in the **Drawing tools** toolbar.
5. Drag on the frame from the tail of the arrow to its tip.
6. Press **D** again to leave drawing mode.

The toolbar floats over the viewer and hides while the video plays, so pause first. **D** returns to the tool you used last, which is the Pen the first time. **Esc** doesn't leave drawing mode.

## Choose another tool

* **Pen** for freehand marks. Press **B** to choose it.
* A shape button that remembers your last choice: **Rectangle**, **Circle**, **Line**, or **Freeform shape**.
* **Arrow**. Select it again to switch to **Arrow + Text**, which asks for a label after you drag.
* **Text**. The **Font size** slider in the left panel runs from 10 to 120.

The shapes and the plain **Arrow** belong to the full tool set, which is on by default. Turn it on or off under **Drawing settings** (the gear).

## Fix a mistake

1. Select **Undo**, or press `⌘Z` (`Ctrl+Z` on Windows and Linux).
2. To bring the change back, select **Redo**, or press `⌘⇧Z` (`Ctrl+Shift+Z` or `Ctrl+Y`).

::: warning
A frame has one shared drawing. Anyone who can draw on it can erase what you drew, and you can erase theirs.

## Save and share your drawing

revis.io saves a drawing about a second after each stroke and when you leave drawing mode. There is no **Save** button. If saving fails, an error titled **Sketch** appears; draw the stroke again. People in the same live session see your strokes as you draw them.

A frame with a drawing shows an orange tick on the timeline. Select **Previous annotation** or **Next annotation** to jump between frames with drawings or comments. Drawings don't appear in the **Notes** list.
