Description
Truncate text to a maximum length with smart word boundary breaking.
How to Use
1
1. Send a POST request with `text` and `max_length`.
2
2. Optionally configure `suffix` (default `...`) and `word_boundary` (default `true`).
3
3. If the text is already within the limit, `truncated` will be `false` and the original text is returned.
About This Tool
Text Truncate shortens text to a maximum character length, optionally breaking at word boundaries to avoid cutting words in half. It appends a configurable suffix (default `...`) and reports the original and truncated lengths.
Why Use This Tool
- UI display — Truncate titles, descriptions, or previews to fit fixed-width layouts
- SEO — Trim meta descriptions to recommended character limits
- API responses — Limit text field lengths in output payloads
- Token estimation — Use `estimated_tokens` for rough LLM context budgeting
Frequently Asked Questions
How does word boundary breaking work?
When `word_boundary` is `true`, the truncation point is moved back to the last space character, avoiding mid-word cuts. It won't break more than halfway back to prevent excessively short results.
Is the suffix included in the max_length?
Yes. The suffix length is subtracted from `max_length` to determine how many characters of the original text to keep.
