Can it type while I am presenting full screen?

No. Slides are not editable in the presenting view, so there is nothing to type into. Run the demo from the editor and share that tab.

Why does Typist ask me to click into a text field?

Usually because the text box is selected but not being edited. Click inside the text again until the blinking cursor appears, then press Start.

Can it fill several text boxes in one run?

No. One run types into one focused box. Typist does not click, switch slides, or move between boxes for you.

Does my text leave my device?

The text in the panel stays on your device and is sent only to the page being typed into. The single exception is a snippet you deliberately save, which is stored so it can sync. See the privacy page.

Google Slides

An auto typer for Google Slides

Typist types text you prepared earlier into a Google Slides text box, at a speed you set, so a slide can fill in line by line while you talk over it.

Where this is useful

Most of the time a slide is finished before anyone sees it, and pasting is the right way to get text onto it. Typing it in progressively earns its place in a narrower set of cases: a speaker demo where you build a slide in front of the room, a walkthrough of how to use Slides itself, or a recording where a bullet list should appear one point at a time instead of all in one frame.

In each case you are talking and do not want to be typing too. Write the text beforehand, put it in the Typist panel, and let it go in at a pace people can follow.

Click in until you see the cursor

This is the one Slides-specific step, and it is the reason a first attempt usually fails. Slides has two different states for a text box. Click it once and the box is selected: you see its outline and handles, but there is no cursor, and typing goes nowhere useful. Click inside the text again and you are editing: a blinking cursor appears in the text.

Typist needs that second state. Before you press Start, look for the blinking cursor inside the box. If you press Start with only the outline showing, Typist does not guess where the text should go; it stops and asks you to click into a text field.

Step by step

Open the presentation in the Slides editor in a normal Chrome tab, not in the slideshow view.
Click into the text box where the text should go, and check that its cursor is showing. Place the cursor at the end of any text already there if you want to add to it.
Open the side panel and sign in with Google, which is required before typing and asks only for your account identifier and email address.
Put your text in the panel, or load a saved snippet.
Choose a speed and pacing mode. The range is 20 to 400 words per minute, with 60 as the default.
Press Start. Pause, resume and stop all work mid-run, and a progress indicator shows how far along you are.

Tips for a speaker demo

Type in the editor, not the slideshow. Nothing on a slide is editable in the full-screen presenting view, so there is no field to type into there. If the demo is the slide being built, share the editor tab instead.
Go slow. If the room is meant to read along, 40 to 60 words per minute in Natural mode, which pauses briefly at punctuation, gives people time. Typing speed control has more on picking a number.
Use pause as your cue. Let one bullet land, pause, talk about it, then resume. The run carries on from the same character.
One box per run. A title and a body are two text boxes, so they are two runs. Type the first, click into the next box, and start again. Save each block as a snippet so it is ready to load.
Check the box size first. Depending on the box's text-fitting setting, Slides may shrink the text or let it run past the edge as it fills. Rehearse once at full length so there are no surprises.
Line breaks start new lines. A line break in your text starts a new line in the box, just as pressing Enter would, so lay out bullet points in the panel the way you want them on the slide.

For live demos more generally, in any app rather than just Slides, see auto typing for demos and presentations, and for recorded walkthroughs see auto typing for screen recordings.

What it costs

The free plan covers 300 words a day, resetting at 00:00 UTC, which is plenty for a few slides. Words are counted when you press Start, so a rehearsal uses the allowance just as the real run does. Free accounts keep three saved snippets. Pro is $4.99 a month and removes both limits; see pricing.
