Check Whether a Text Slide Stays Up for Your Chosen Reading Pace
A dense slide can disappear before a viewer finishes reading it. Convert the visible word count to seconds at a reading pace you chose and compare that with the display time.
1 · slide | words on screen | display seconds
FIRST-LOAD
Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the slide dwell-time meter: your slide | words on screen | display seconds stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Only count the content the viewer must read on the displayed slide. After: the slide dwell-time meter shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Reading-time arithmetic only, not an accessibility standard, accommodation decision or comprehension test. Ask the audience, follow accommodation requests and provide accessible slides and alternate ways to review the information. It does not measure whether viewers actually understand a slide.

- For any threshold or rule, use the current value from the provider, handbook or qualified professional responsible for it.

Optional AI formatting, not calculation
For this slide dwell-time meter, an external AI text tool may help format non-sensitive notes if you already use one. No AI service or account is required: manual entry completes the same free core calculation. Do not paste private or sensitive data. Review every value against the source before using it.
Format my non-sensitive notes for a slide dwell-time meter. Return plain rows only: slide | words on screen | display seconds. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: slide | words on screen | display seconds. No AI response is executed as code.
