HOW TO

How to use Context Optimizer

Reduce unnecessary tokens before using documents with AI or RAG.

  1. 1

    Paste text or choose a supported text document, PDF or DOCX.

  2. 2

    Process it and compare the original and cleaned token counts.

  3. 3

    Inspect removed repetition and line wrapping before copying or downloading the cleaned context.

INPUT AND OUTPUT

Remove extraction clutter while keeping the source for comparison

This deterministic cleanup targets page labels, excess spacing, broken line wrapping and some line-end hyphenation. It can remove repeated short lines across pages when recognizable page separators are present. It does not ask an AI model to rewrite or summarize your document.

Without recognizable page separators, repeated headers may remain. Repeated lines can also be meaningful content. Check headings, legal clauses, lists and code before replacing the original text. A lower token count is not proof that the cleaned version retains every important detail.

FAQ

Common questions

Are my files uploaded?+

No. This tool processes files in browser memory on your device.

Is the tool free?+

Yes. Core processing is free, requires no account, and adds no watermark.

Is context optimization an AI summary?+

No. It applies local text-cleaning rules rather than calling a model or deciding what ideas to summarize.

Can the cleanup remove something I wanted to keep?+

Yes. Repetition and line-break heuristics can affect meaningful text. Compare the result with the source, especially for code, tables and repeated clauses.
