What the Text Analysis Tool Does and Why It Matters
The Text Analysis tool inspects a block of text and reports word count, readability, keyword density, and a simple keyword-based sentiment read, entirely in your browser. It gives a quick, objective profile of writing rather than just a word total.
This matters when you want to understand or improve a piece of text — checking that it is readable for its audience, that no keyword is over-stuffed, and that the overall tone leans the way you intend, without sending the draft to an external service.
How to Use Text Analysis
- Paste the text you want to analyze.
- Run the analysis to compute the metrics.
- Read the readability score, word count, and keyword density.
- Check the simple sentiment indicator for overall tone.
- Revise the text and re-run to see the metrics change.
Supported Inputs and Limitations
What you provide
- A block of text pasted into the tool
What you get
- Word count and readability metrics

Known limitations
- Sentiment is a lightweight keyword heuristic, not a trained language model, so it can miss sarcasm and nuance.
- Readability formulas approximate difficulty and are guides, not absolute judgments.
- It analyzes English-style text best; other languages may score less reliably.
Privacy and Security
All analysis runs in your browser. Your text is processed on your device and is never transmitted to NovaTools or any external service.
Frequently Asked Questions
How accurate is the sentiment read?
It is a simple keyword-based estimate of overall tone, useful for a quick gauge but not a substitute for careful human reading or an AI model.
What does the readability score mean?
It approximates how easy the text is to read based on word and sentence length, helping you match the text to your audience.
Is my text uploaded?
No. Everything is computed locally and the text stays in your browser.
