Find the Captions Viewers Cannot Finish Reading — Free

Export your captions with timings and the gauge ranks them by the reading speed each one demands, so the three a viewer cannot finish are named rather than sensed.

What this replaces

Caption guidelines quote a maximum words-per-minute figure and leave you to find the lines that break it. This ranks every caption by the speed it demands, so the three that are impossible to finish are at the bottom of the list rather than spread through a hundred you would have to check by hand.

Tool note. This runs entirely in your browser — no account, no upload, no paid API key. Google NotebookLM is named as the free source-grounded reading path for the material you paste; its published free-tier terms were checked on 2026-09-13 and can change.

The four passes

01

Collect the smallest useful input

One caption per line with words, seconds on screen, and the resulting wpm.

02

Let the gauge rank them

Each gets a score with the two numbers behind it, easiest first.

03

Fix the bottom three first

Those are the ones a viewer cannot finish.

04

Re-export and rerun

A fixed caption should move up the ranking.

Try it on the caption gauge / clip 4

The board below runs in your browser. It opens with a worked sample so the result is visible before you paste anything; switch scenarios, edit the text, or reset to the sample.

Everything you paste stays in this browser tab. Nothing is uploaded, there is no account, and no request leaves the page to generate the result; clearing site data removes anything saved locally.

What breaks, and what to do

wpm not stated

Only the words figure is scored; compute wpm as words divided by minutes.

Captions that flash for under a second

Worse than any score here; check them by eye.

Burned-in captions

Nothing can be exported; you will need to type the lines.

Go deeper — Caption Gauge

The free board above is the whole loop. The paid tier keeps the arranged output so you do not rebuild it.

  • Printable gauge with the failing captions boxed for the editor — estimate: 18 minutes saved per clip, basis: 5 captions re-checked at ~3.6 minutes each
  • Saved local history across clips — estimate: 12 minutes saved per clip, basis: re-entering 5 captions at ~2.4 minutes each
