I've been making subtitles since 1982. Here is what AI got wrong.
Transcription became fast, cheap, and accurate. That part of the story is real. But something else happened at the same time. Many subtitles became harder to watch. The reason is simple: getting the words right is only the first part.
Transcription gets the words right.
Subtitling makes them readable.
Transcription is turning speech into text. Subtitling is turning that text into something a viewer can actually read while watching a video. How fast the text appears. Where the lines break. How long each block stays on screen. Whether the timing follows the rhythm of the speaker. AI caption tools solved the first problem. The second was largely left behind.
So we decided to do something about it. A free SRT editor that grades any subtitle file against professional standards. Every cue is checked for reading speed, line length, timing, gaps, overlaps, and formatting errors. The file gets an overall grade from A to F.
It runs entirely in your browser. Nothing is uploaded. No account required.
We did not build it to gate the knowledge behind a paywall. The standards that make subtitles readable should not be locked inside professional studios. Anyone producing video should be able to check their work against real standards.

Take this sentence: "She handed him the keys and said she would be back by morning."
Badly segmented:
She handed him
the keys and said she would be
back by morning.
```
Well segmented:
She handed him the keys
and said she would be back by morning.
```
Same words. Different reading experience. Line breaks are one part of it. Reading speed is another. A subtitle can be perfectly accurate and still fail if it disappears before the viewer has time to read it.
That is why the editor checks subtitles the way professional subtitlers do: not just for correct words, but whether they are readable on screen.
If you work with video and use auto captions, does this match what you see? Curious whether the quality gap resonates with others here.
