Keyword Density Checker
Measure literal keyword or phrase frequency with a visible density formula.
BUILT AROUND YOUR WORK
Prepare a recording and publishing session. Start with the draft script, target duration, and asset requirements. Use the relevant tools below to check text length and prepare media, then keep a recording-ready script and upload assets alongside the source material.
USE WITH CONTEXT
Review platform rules and rights before downloading or republishing material. Keep claims, captions, and generated drafts accurate and attributable.
A PRACTICAL ROUTE THROUGH THE SHELF
Bring the draft script, target duration, and asset requirements. Record where the values came from and which assumptions are still uncertain.
Choose a tool to check text length and prepare media. Read its method and limits, then run a small example before working through the full scenario.
Keep a recording-ready script and upload assets. Read the script aloud and preview captions and images before publishing.
Measure literal keyword or phrase frequency with a visible density formula.
Extract plain text from bounded HTML without rendering or fetching resources.
Measure grapheme characters, characters without spaces, UTF-8 bytes, and lines in the browser.
Remove Latin-only or all combining marks with explicit lossy-output warnings.
Convert source sentences or lines into traceable list items without paraphrasing.
Alphabetize line-based names and phrases with optional leading-article handling.
Keep the first occurrence of each whole line with explicit case and blank-line rules.
Report selected invisible Unicode code points and positions without deleting them.
Convert text to lower, upper, sentence, title, or toggled case without uploading it.
Build a limited plain-text APA, MLA, or Chicago web citation candidate.
Remove or visibly replace recognized joined, flag, keycap, and pictographic sequences.
Replace every literal text occurrence safely with optional case-sensitive matching.
Trim lines, collapse horizontal spacing, and reduce repeated blank gaps in prose.
Estimate sentence boundaries and report supporting word and character counts locally.
Apply conservative fence-aware Markdown whitespace and bullet cleanup.
Estimate English Flesch readability metrics with documented syllable heuristics.
Apply NFC, NFD, NFKC, or NFKD normalization with code-point metrics.
Create an English-style title-case first pass with documented minor-word rules.
Group explicitly marked notes, decisions, and actions without summarization.
Count words, characters, sentences, and blank-line paragraphs locally with Unicode-aware segmentation.
Reverse grapheme clusters locally without splitting common joined emoji or combined letters.
Sort plain-text lines with numeric collation, direction, case, and blank-line controls.
Wrap escaped plain text in paragraph, line-break, or list markup.
Count blank-line paragraphs with sentence, word, and physical-line context.
For this workflow, begin with the draft script, target duration, and asset requirements. Choose the tool whose inputs match the task, rather than entering incomplete values into a broader calculator. The intended outcome is a recording-ready script and upload assets.
Read the script aloud and preview captions and images before publishing. Review platform rules and rights before downloading or republishing material. Keep claims, captions, and generated drafts accurate and attributable.
