Who is this for?
Word Counter Pro Tool is built for anyone who writes — which is most people. Some of the most common uses:
- Students — checking essay and assignment word counts against submission limits
- Content creators — fitting captions to Instagram, LinkedIn and TikTok limits
- Social media managers — optimising posts for each platform before publishing
- Writers and bloggers — tracking article length and reading time
- Professionals — keeping emails and reports concise
- Developers — checking meta descriptions, UI copy and character limits
How it works
The tool is a single web page — there is no app to download, no account to create and no server processing your text. When you type or paste text into the editor, JavaScript running in your browser analyses it instantly and updates all the counts in real time.
The AI content fitting feature uses the Claude API. If you choose to use it, the text is sent securely to Anthropic's servers for processing using your own API key, which is stored only in your browser's local storage and never transmitted to us.
