How to use it

  1. Paste your slides. Put a blank line between slides, or one slide per line.
  2. Check the verdict on each slide. Slide 1 is judged as the hook (up to 14 words), the others as content slides (up to 20 words), and the last one as the call to action (up to 12 words) when you leave that option on.
  3. Cut the slides marked Too long, and rewrite the lines the phrase check flags. The results update as you type.

A viewer gives a photo slide about three seconds before swiping, and skims about four words a second. That is why the hook gets 14 words, a content slide 20 and the call to action 12. Line breaks are not counted as characters.

The phrase check is the same deterministic lint Reelazy runs on every post its AI writes. It catches leftovers and habits, not facts: read every slide yourself before you post.

Frequently asked questions

How many words should a TikTok slide have?

Up to 14 words (about 90 characters) for the hook, 20 words (up to 160 characters) for a content slide and 12 words for the call to action. A viewer gives a slide about three seconds and skims about four words a second.

How does it spot AI-sounding text?

With a fixed list of rules, the same ones Reelazy runs on every post it writes. It flags chatbot leftovers (citation markers, Markdown symbols, lines like "Here are your slides"), unfilled placeholders, stock phrases such as "game-changer" or "unlock your potential", the same "it's not X, it's Y" line used more than once, repeated lines and openings, and dashes on many lines. It is a style check, not an AI detector.

Does it work in Vietnamese and other languages?

Yes. Words and characters are counted correctly with accents and in languages without spaces. The phrase lists cover English and Vietnamese; other languages get the checks that do not depend on words, such as repeated lines and dashes.

Is my text sent anywhere?

No. The checker runs in your browser. Nothing you paste leaves your device and no AI is called.

What should I do when a slide is too long?

Cut words, never shrink the type. If a slide carries two ideas, split it into two slides. If that takes the post past eight slides, cut an idea.
