You can extract keywords from text online by pasting text into a keyword extraction tool or using AI to identify the most important terms, entities, and phrases.

Short answer:

To extract keywords from text online, provide the text, detect recurring terms and named entities, rank them by relevance, and keep source context so the keywords remain useful later.

What Online Keyword Extraction Does

Online keyword extraction tools identify words and phrases that represent the main topics in a piece of text. They often look for frequency, uniqueness, headings, noun phrases, and semantic relevance.

This is useful for quick summaries, tagging, search, SEO, and organizing large sets of documents.

Why AI Improves Keyword Extraction

Traditional tools often focus on frequency. AI can identify concepts that matter even when the exact word appears only a few times.

For example, a document may talk about incident reporting, client notification, and audit evidence without repeating one neat keyword throughout the file.

The Limitation of Simple Keywords

Keywords can tell you what a text is about, but they do not always answer the question a team cares about. A policy may contain the keyword 'notification' without explaining which deadline currently applies.

That is why keyword extraction should feed into grounded question answering, not replace it.

How Manex Uses Extracted Context

Manex treats extracted keywords and entities as part of a larger document memory workflow. The important step is connecting terms to source passages, corrected answers, and future retrieval.

The keyword becomes useful when it helps the team find and reuse the trusted answer.

Where Manex Fits

Manex helps teams move beyond isolated keyword extraction. It turns documents into grounded answers, corrections, source context, and reusable memory.

For document-heavy teams, the goal is not only to identify important terms. It is to preserve the trusted answer those terms help uncover.
