Finding your way around

The dashboard has two tools, both available from the side panel on the left:

• Editor: a full writing workspace with AI proofreading, tracked changes, and document management.
• AI Humanizer: rewrites AI-assisted text in a natural human voice, up to 1,000 words per pass.

The side panel can be pinned open or collapsed to a narrow icon rail. Use the panel icon in its top corner to switch between the two states. The panel also lists your documents, your humanization history (on the Humanizer tab), and links to your Account, this User Guide, and Log Out at the bottom.

EDITOR

Quick start

1. Paste or type your text into the editor.
2. Pick a proofreading depth (Light, Standard, or Comprehensive) and click Apply.
3. Review the tracked changes in your text and the suggestions panel on the right, accepting or rejecting each edit.
4. Export to Word or PDF, with or without tracked changes.

Proofreading and editing

Three depths are available from the toolbar. For higher-quality results, edit fewer than 600 words at a time.

• Light: grammar, spelling, and punctuation only. The safest option for text that has already been humanized.
• Standard: grammar plus clarity and flow improvements.
• Comprehensive: a deeper rewrite for readability and style.

Suggestions panel

Every edit appears as a suggestion in the panel on the right, grouped by category. Click a suggestion to jump to it in the text, then accept or reject it individually.

Tracked changes

Edits show inline as insertions (green underline) and deletions (red strikethrough), Word style.

• One change: click directly on an insertion or deletion, then use the Accept or Reject buttons that pop up.
• Several changes: highlight a passage and accept or reject everything inside it at once.
• All changes: use Accept All or Reject All in the toolbar.

Tense conversion

Select Past, Present, or Future under Tense in the toolbar. All tenses throughout the text are adjusted automatically, with every change tracked.

Citations adjustment

Choose APA, Chicago, IEEE, MLA, or Turabian under Citations. All in-text citations are converted to the selected format automatically.

UK / US English conversion

Switch between UK and US spelling from the toolbar. The text is converted automatically (colour to color, organise to organize, and so on).

Expand, paraphrase, summarize

Under Text Processing, three one-click transformations are available:

• Expand: lengthens the text with supporting detail.
• Paraphrase: rewords the text while preserving meaning.
• Summarize: condenses the text to its key points.

Translation

Click Translate to in the toolbar and pick a target language. The document is translated in place, with changes tracked like any other edit.

Exporting your document

Export your document as Word or PDF, either clean or with tracked changes included, ready for supervisors and co-authors. You can also copy the text with its tracked changes and paste it directly into Microsoft Word.

Edit metrics

The bar at the bottom of the editor shows live document statistics: characters, words, and reading time, plus optional readability, writing quality, and AI detection scores. Toggle the optional metrics from the user menu.

AI HUMANIZER

Who the AI Humanizer is for

The AI Humanizer rewrites AI-generated text into natural, human-sounding writing while preserving your meaning, citations, and terminology. Whether your draft comes from ChatGPT, Claude, Gemini, or any other AI writing tool, the humanizer removes the patterns AI detectors flag and returns text that reads like it was written by you.

• Academic researchers and students: humanize AI-assisted essays, theses, dissertations, literature reviews, and journal manuscripts in Academic mode. Citations, statistics, and discipline-specific terminology are preserved exactly, and the output keeps a formal academic register.
• SEO content writers and marketing teams: humanize AI-generated blog posts, landing pages, and product descriptions in Blog/SEO mode. Protect your primary, secondary, and long-tail keywords through the rewrite and publish human-sounding content at scale.
• Business professionals: turn AI-drafted reports, proposals, emails, and internal communications into a polished business voice in Corporate mode.
• Creative writers and bloggers: give AI-assisted drafts a livelier, more personal voice in Creative mode.
• Writers in any language: humanize AI text in 67 languages, from Spanish, French, and Arabic to Chinese, Japanese, Hindi, Urdu, and Hausa, with automatic language detection built in.

Quick start

1. Open AI Humanizer from the side panel.
2. Paste your AI-assisted text into the input pane, or upload a .docx or .txt file. Use body paragraphs only: titles, headings, tables, and figures are rewritten as plain paragraph text, so remove them first.
3. Set the intensity and writing mode.
4. Click Humanize. A typical pass takes 15 to 45 seconds; long passes can take longer.
5. Review the result, then copy it or export it in your preferred format.

Humanization intensity

The slider controls how deeply the text is rewritten:

• Mild: keeps the best readability but is more likely to be flagged by AI detectors.
• Mild+: a slightly deeper rewrite that still puts readability first.
• Balanced: the best tradeoff between readability and detection passing. Recommended.
• Strong: a deeper rewrite for a higher detection pass rate, with most of the readability intact.
• Aggressive: passes detectors at the highest rate with slightly lower readability.

Writing modes

• Academic: preserves citations and expands contractions. For theses, papers, and reports.
• Corporate: a polished business voice.
• Creative: livelier, more expressive prose.
• Blog/SEO: a conversational voice for web content, with SEO keyword protection (see below).

Language support (67 languages)

The humanizer works in 67 languages, from Spanish, Arabic, and Chinese to Urdu, Hindi, and Hausa. Your language is detected automatically: when a non-English language is recognized, a small note appears under the input pane. To override detection, pick the language from the Language dropdown. The US/UK spelling toggle applies to English text only and is disabled for other languages.

Freeze terms

Freeze terms are words or phrases the humanizer must keep exactly as written, character for character. They are made for academic and technical writing: author names, in-text citations, reported statistics like p < 0.05, chemical formulas, and discipline-specific terms that must not be paraphrased.

• Type a term and press Enter or comma. Terms must appear in your input text; up to 10 terms per pass.
• Frozen terms are highlighted in amber in your input and in the result, so you can confirm they survived unchanged.
• After a pass completes, the field clears for your next text and the terms move to one-click chips below it for easy reuse.

SEO keywords (Blog/SEO mode)

Content writers have a different problem: search rankings depend on exact keyword phrases surviving the rewrite. In Blog/SEO mode the field becomes SEO keywords. Add your primary, secondary, and long-tail keywords and the humanizer keeps every one of them exactly as written while it rewrites the text around them, so your humanized article stays optimized for the queries you are targeting.

• Works the same way as freeze terms: Enter or comma to add, up to 10 keywords per pass, and each keyword must already appear in your draft.
• Protected keywords are highlighted in amber in the output, an instant visual check that your on-page SEO survived the humanization.

Reviewing your result

The output pane has three views:

• Plain: the finished text, ready to copy.
• Insertions: highlights the newly written parts.
• Diff: a full comparison against your input, with insertions and deletions marked.

Below the panes, the metrics bar shows your Human Score along with rewrite percentage, readability, perplexity, and burstiness. Hover the info icons for a plain-language explanation of each metric.

Exporting and copying

Use Copy for a quick clipboard copy of the plain result. The Export menu offers Word and PDF (clean or with tracked changes), plain text, and HTML. In addition, Copy as Markdown and Copy as HTML produce CMS-ready paragraphs for WordPress, Ghost, and similar editors.

Re-humanize and Proofread in Editor

• Re-humanize: runs the output through another pass for a stronger rewrite. Each pass uses words from your allowance.
• Proofread in Editor: saves the result as a new document and opens it in the editor. Caution: use Light Proofreading only, as heavier AI editing can raise the AI detection score again.

Humanization history

Your recent runs are listed in the side panel while you are on the Humanizer tab. Click any entry to restore that run, including its input, output, and settings. History is stored on your device only.

Word limits and passes

• Each pass accepts between 50 and 1,000 words.
• For longer documents, split the text into sections and humanize them one pass at a time.
• Humanization uses words from your monthly plan allowance; there are no separate credits. Your remaining words are always visible in the header.
