About Text Length Tools

Text Length Tools is a collection of free, browser-based text analysis tools. Every tool runs entirely in your browser: no text is sent to a server, and nothing is stored.

What the tools do

The tools cover several categories of text analysis and formatting:

• Counting tools: word count, character count, sentence count, paragraph count, line count and text analysis.
• Reading & speaking time: estimate how long text takes to read or deliver as a speech, at different speeds.
• Social media character limits: check text against character limits for Twitter/X, LinkedIn, Instagram, TikTok, Facebook, YouTube and other platforms.
• SEO & metadata: check title and meta description lengths, preview how content might appear in search results.
• Writing guides: word count targets and context for essays, blog posts, cover letters, reports and academic writing.
• Author tools: word count norms for novels, novellas, short stories, flash fiction, synopses and query letters.
• Text formatting: case conversion, line sorting, deduplication, text-to-HTML, Markdown conversion, slug generation.
• AI text cleanup: rule-based formatting cleanup to remove Markdown, replace em dashes, strip common assistant-style phrases and normalise punctuation. These tools do not detect AI or claim to modify authorship.

What the tools don't do

• Store, transmit or analyse your text on a server.
• Require an account or any form of sign-up.
• Rewrite your text, improve it, or make editorial suggestions.
• Detect AI-generated content or claim to "bypass" AI detection.
• Guarantee that any platform limits are official or permanent: platform policies change.

Data & privacy

Text you enter into any tool is processed using JavaScript running in your browser. It is not sent to any server. See the Privacy Policy for more detail.

We may use standard web analytics (such as page view tracking) that collects aggregated, anonymised data about how tools are used. We may also display advertising in future. Neither of these involves your text.

Platform limits & accuracy

Character limits for social media platforms are based on commonly reported practical values and are reviewed periodically. They are not official API specifications and may not reflect the most recent platform changes. Always verify against current platform documentation before publishing.
