Why do some word counters cap how much text you can paste?
Some writing tools cap free-tier text length or gate keyword density behind a subscription. Neither limitation makes technical sense for a tool that just counts what you already typed.

Why some counters impose an artificial length cap
A number of online word-count tools cap how much text a free user can paste at once, reserving longer documents or advanced features like keyword density for a paid tier. That cap is a business-model decision, not a technical one — counting a 5,000-word article requires the same trivial computation as counting a 50-word paragraph.
The Word Counter has no practical length cap: paste a full article or blog post and it counts instantly, using Intl.Segmenter for accurate word and character counting, since everything runs against your own device's resources rather than a server-side limit.
Why keyword density should never be a paywalled feature
Keyword density — how often a word appears relative to total word count — is arithmetic, not a proprietary algorithm worth gating. This tool surfaces it free, as a diagnostic to spot accidental over-repetition or confirm your intended topic actually dominates the piece, never as a target to write toward.
The accuracy detail a length-capped tool often gets wrong too
Beyond the cap itself, plenty of simple counters use naive character-length counting that misreports emoji and multi-script text — an emoji built from several Unicode code points reports as 8 characters via naive .length, when a reader perceives one. This tool counts grapheme clusters instead via Intl.Segmenter, so the number matches what you actually see on screen.
Reading and speaking time, without an upsell
Reading time uses 238 words per minute from a real 2019 meta-analysis; speaking time uses 130 wpm — both free, alongside platform character badges for X, meta titles, meta descriptions and LinkedIn posts, so a long document fits its destination without pasting into a separate checker. Fitting a title tag to that meta-description badge feeds directly into the on-page basics the AI Visibility Checker scores, so the two tools work well as a pair.
When word count is the smallest problem
Hitting a length target is mechanical. Whether the content actually targets the right keyword and earns a citation is a harder question — the work Scult's SEO and content team does, or book a meeting to talk through your content plan.
