Generate Text N-grams

Q: What is an N-gram?

An **N-gram** is a contiguous sequence of *n* items from a given sample of text or speech. In this tool, the items are words. Common examples are unigrams (n=1), bigrams (n=2), and trigrams (n=3).

Q: Why are N-grams used in NLP?

N-grams are fundamental for **probabilistic language models**. They help predict the next word in a sequence (e.g., predictive text), correct spelling, and analyze context. They capture the structure of language better than single words alone.

Q: What is the maximum 'N' size I can set?

Our tool allows you to adjust the slider up to **10-grams**, which is sufficient for almost all linguistic and SEO purposes. However, the logic supports any integer size if you need larger sequences.

Q: How does the 'Stop Words' filter handle N-grams?

When enabled, the tool will **exclude any N-gram** that contains a stop word (like 'the', 'is', 'at'). This is useful for finding content-rich phrases, but be aware it might break the natural flow of common idioms.

Q: Can I use this for plagiarism detection?

Yes! Matching **high-order N-grams** (e.g., 5-grams or 6-grams) between two documents is a very strong indicator of copy-pasting, as it is statistically unlikely for two people to write the exact same 6-word sentence by chance.

Q: Does punctuation count as part of the N-gram?

By default, we **ignore punctuation** to focus on word sequences. However, you can toggle punctuation on if you want it included in the tokens (e.g., distinguishing 'end.' from 'end').

Q: Can I analyze large text files?

Yes, you can upload **.txt or .md files** directly. The processing happens in your browser, so it's fast and private. Extremley large files (hundreds of MBs) may be slower depending on your device's memory.

Q: What export formats are available?

You can download your analysis results as a **CSV file** (readable by Excel/Google Sheets) or a **JSON file** (for developers). You can also copy the list directly to your clipboard.

Q: Is this tool free?

Yes, this N-gram generator is **100% free** to use without usage limits. No account or login is required.

Analyze contiguous sequences of N words (Trigrams, 4-grams, etc.) in your text.

Analyze Text Patterns with N-Grams

The Generate Text N-grams tool gives you granular control over text analysis. Unlike fixed tools, this flexible analyzer lets you define the sequence length (N) to discover everything from common Trigrams (3 words) to specific 5-word phrases. It's an essential utility for linguistics, SEO keyword research, and training AI models.

Advanced Capabilities

Adjustable 'N'

Slide to select any sequence length, from simple Bigrams (2) to complex 10-grams.

Smart Filtering

Exclude stop words and numbers to reduce noise and focus on meaningful content.

Data Export

Download your frequency distribution data as CSV or JSON instantly.

File Support

Process entire documents by uploading .txt or .md files for analysis.

Detailed Stats

Get total counts, unique counts, and percentage frequency for every sequence.

Deep Search

Filter your result list to find specific phrases in seconds.

Common Use Cases

AI & Machine Learning

N-grams are the building blocks of language models. Use this tool to preprocess training data or understand the probabilistic structure of a corpus.

Plagiarism & Attribution

Compare document fingerprints. If two texts share many unique 5-grams or 6-grams, it's a strong sign of shared authorship or copying.

Examples

Trigram Extraction (N=3)

Input:

The quick brown fox jumps

Output (Trigrams):

1. The quick brown
2. quick brown fox
3. brown fox jumps

4-gram Frequency

Input:

To be or not to be that is the question

Top 4-grams:

1. To be or not
2. be or not to
3. or not to be

How to Use

Input Text: Paste your content or upload a file.
Set N-Size: Use the slider to choose the sequence length (e.g., 3 for Trigrams).
Configure Filters: Enable "Stop Words" to clean up noise or "Ignore Numbers" for pure text analysis.
Analyze: Review the frequency table generated instantly.
Export: Save your data as CSV or JSON for offline use.
