ULTRANEW!

ULTRA: The Maximum Rewrite for Long-Form Content

Set the slider to ULTRA when a blog post or a landing page needs the max AI score reduction rate. Your SEO keywords are preserved verbatim with freeze terms.

AI score reduction vs. Semantic Faithfulness vs. grammar

025507510050%59%68%76%78%89%MildModerateBalancedStrongAggressiveULTRA
  • AI score reduction (GPTZero, %)
  • Semantic Faithfulness (NLI support × 100)
  • Grammar (LanguageTool flags per 1,000 words)
From Mild to Ultra, the AI score reduction increases from 50% to 89%. AI score reduction increases at the cost of a slightly lower semantic faithfulness, grammar, and overall readability.

The sixth setting on the slider

ULTRA is the highest of the six intensity settings, above Aggressive. It is the maximum rewrite, and it uses its own state-of-the-art fine-tuned model.

The highest AI score reduction rate

On GPTZero the AI score reduction rate rises from 50% at Mild to 78% at Aggressive and 89% at ULTRA.

Citations and figures preserved verbatim

Key terms, citations, numbers and your freeze terms are preserved verbatim at ULTRA, as at every other intensity.

Revise before you submit

ULTRA prioritizes the highest AI score reduction rate possible, at the cost of slightly lower readability & grammar. Revise output before submission.

ULTRA comes with the Plus plan and also works in the humanizer dashboard and in the Doc Humanizer. It works on English text only.

Humanize a Whole Content Piece in One Upload

Upload a long-form article, an ebook chapter or a case study as a .docx, up to 15,000 words, and download it humanized with the headings, lists and tables preserved verbatim and your SEO keywords frozen throughout.

One upload of up to 15,000 words

Upload the .docx and the Document Humanizer works through every body paragraph in order, section by section, until the whole document is done. Built for the one-off humanization of a complete file.

Formatting and structure preserved

Headings, lists, tables, captions, equations, footnotes and the reference list are preserved verbatim. Inline citations, hyperlinks and the formatting of the surrounding text stay in place inside the humanized paragraphs.

Clean copy or tracked changes

Download a clean Word file that is ready to submit, or a Word file with every change tracked, so you or your supervisor can accept and reject the edits in Word. A plain-text file is included as well.

Progress window and an email when it is ready

A small window shows how far the humanization has got. Keep working or leave the page, and you get an email when the document is complete and ready to download.

The Document Humanizer comes with the Plus plan. It draws on the same word credit allowance as the AI Humanizer, the cost is shown before you start, and finished documents stay available for download for 30 days.

AI text humanization built for SEO content and marketing copy

Keywords survive the rewrite

Add your target phrases as SEO keywords and the humanizer preserves them word for word, long-tail variations included, while naturalizing everything around them.

On-brand, human copy

Writing modes keep the rewrite aligned with marketing copy instead of drifting academic, and frozen brand terms guarantee product names never change on the way out.

Publish with confidence

Content that scores low on AI detectors is safer for brand trust, guest-post placements, and clients who screen submissions before paying for them.

Humanize AI content for SEO in three simple steps

Built for a content calendar: each humanization takes under a minute, and the controls persist between runs.

01

Paste the draft from your AI stack

Drop in the article, landing page, or campaign copy your team drafted with AI, or upload it as a .docx or .txt file. The word counter shows exactly what the humanization will use.

02

Add SEO keywords, pick the mode

Enter your target phrases so they are preserved verbatim, choose the Blog/SEO writing mode, and set the intensity to match the asset.

03

Verify placements and publish

Check the highlighted keyword placements in the output, review the tracked changes like an editorial pass, and ship copy that reads human.

How TextPulse humanizes AI content for SEO

Naturalize the copy, keep the strategy: keywords, brand voice, and editorial review all stay under your control.

SEO keywords locked and highlighted

Target phrases you add as SEO keywords are preserved exactly in the rewrite and come back highlighted in the output, as in the demo below, so you can verify every placement before publishing.

Long-tail variations are preserved the same way, so a phrase you fought to rank for is never paraphrased out of the page.

Recent:+ email marketing software+ open rates+ marketing automation
Humanized

Choosing the right email marketing software matters less than what you send with it. Campaigns that read like a person wrote them consistently earn better open rates, because subscribers can tell templated copy from a genuine note within two lines. The same rule holds as your stack matures: marketing automation can schedule the sends, score the leads, and split-test the subject lines, but it cannot make a robotic paragraph feel human. Write the message first, humanize it, and let the tooling handle the timing.

Match the rewrite to the asset

A product description needs a light touch. A pillar article can take a deep restructure. Six intensity settings set how deep the rewrite works, and the Blog/SEO writing mode keeps the register in marketing copy instead of formal.

Try the slider below, the same control the dashboard ships with, to see how each stop trades rewrite depth against faithfulness.

Editorial review built in

Editors see every insertion and deletion in the tracked-changes view before sign-off, like a normal editorial pass, with grammatically sound output that needs no cleanup afterward. Flip the example below through Plain, Insertions, and Diff.

On the Plus plan the diff also exports to Word with native tracked changes, so external editors and clients can review in the tool they already use.

Humanized output

In the realm field of natural language processing, this study work delves into investigates transformer architectures through the lens of using semantic understanding — underscoring. This highlights a pivotal major shift in how machines interpret human language. the manner in which human language is interpreted by machines.

ChatGPT, Claude or Gemini draft in. Publish-ready copy out.

TextPulse humanizes content drafted with ChatGPT, Claude, Gemini, Perplexity, Grok, Llama and every major model family, removing the statistical patterns that AI detectors and search quality systems flag in machine-written copy.

Straight to the detector

Drafts from ChatGPT, Claude, Gemini, and other models submitted as-is.

Flagged as AI

Through TextPulse first

The same drafts humanized before they meet the detector.

The Marketing AI Humanizer that Truly Preserves a Brand's Voice

Other humanizers change perspective. A second-person landing page comes back impersonal, or a brand's 'we' turns into a distant third person. TextPulse filters the output to exactly the voice you chose, so the brand voice you wrote in is preserved in the humanization.

Formal academic

The neutral, objective tone of published research. No first or second person is seen in the output.

First person only

'I' and 'we' are preserved. Second person is blocked.

Second person only

'You' is preserved. First person is blocked.

Match my draft

The voice your original text already uses, kept exactly as written.

A common flaw in other humanizers is that they alter your neutral research tone into first or second person. We fixed that. Write the draft in the voice you need, and the TextPulse humanizer engine preserves it.

Humanize AI content for SEO without losing what ranks

AI got content cheap to produce and expensive to trust. Humanizing restores the reader signals that make content worth ranking in the first place.

Target keywords preserved exactly

The SEO keywords feature protects your target phrases through the rewrite, exact-match and long-tail alike, and highlights them in the output for verification. You keep the on-page optimization you planned while everything around it stops sounding generated.

Human-sounding content performs

Search guidance rewards helpful content however it is produced, but readers bounce off robotic copy, and low engagement is a ranking problem no keyword density fixes. Humanized content restores the sentence variety and rhythm that keep people reading to the end.

Scale the calendar without sounding scaled

Ten AI articles read like one author published ten times. Run each piece through the humanizer with the same mode and brand freeze terms, and the calendar ships at volume while every piece keeps a human pulse. A full humanization takes under a minute per asset.

Brand voice, enforced

Freeze product names, taglines, and compliance-approved wording so they never drift, and keep the whole team on one writing mode for a consistent register in every deliverable. Tracked changes give editors final say before anything carries the brand's name.

What content teams humanize with TextPulse

Every asset in the content calendar that starts as an AI draft and needs to publish as human writing.

Humanize AI content for SEO articles

Long-form pieces keep their target keywords verbatim while the surrounding prose sheds the machine cadence detectors and readers notice.

AI content humanizer for blog posts

Weekly posts come out in your brand's own voice, with the shared model cadence removed.

Landing pages

Conversion copy reads persuasive and human while product names and taglines stay frozen exactly as legal approved them.

Email campaigns

Sequences that sound like a person wrote them earn replies; humanized sends lose the template rhythm AI drafts share.

Humanize AI copy for social media

Short posts humanize in seconds, keeping hooks and hashtags intact while the voice turns back into your brand's.

Product descriptions

Catalog copy at scale without the copy-paste feel: attributes and specs stay exact while every description reads fresh.

TextPulseMicrosoft Word

Export Tracked Changes to Microsoft Word

Editorial sign-off without extra tooling. The word-level diff exports as a .docx file with native tracked changes, so editors, clients, and compliance can review the humanized copy in Microsoft Word, accept or reject each edit, and approve the piece in the workflow they already use.

The research behind the content humanizer

Three published studies on machine-written text: how 11 humanizers compare on detector scores and meaning preservation, how far the major AI detectors agree with each other, and which writing signals mark copy as machine-generated. Corpus, scores and code are published with each one.

The best AI humanizer for SEO and content marketing: how TextPulse compares

Most AI humanizers paraphrase your target keywords away. TextPulse locks them word for word, holds the brand register, and shows every edit before the piece publishes.

What Google actually says about AI content

Google's March 2024 spam update introduced the scaled content abuse policy, and its terms are worth reading precisely. The policy is method-agnostic: AI-generated content is not banned, and mass-produced pages that exist to rank and do not help users are spam however they were made. Google's own announcement spells this out. Enforcement was not theoretical: manual actions deindexed entire sites, and Google said the update aimed to cut low-value content in results by 40%.

The practical reading for a content team: AI-assisted production is fine, sounding AI-produced is the risk. Copy that carries the statistical fingerprint of raw model output is easy for platforms, clients and readers to spot. TextPulse's Blog/SEO mode humanizes drafts while freeze terms hold your target keywords in place, so the copy keeps its search intent and loses the machine cadence.
