How to Use Grammarly AI Rewording Tool: A Practical Walkthrough

The Rewording Confusion: What Grammarly Actually Offers

You've heard Grammarly can reword your text, opened the app, and found no button labeled "Reword." That's not a glitch — Grammarly genuinely doesn't have a dedicated rewording tool. Multiple independent reviews confirm it "does not have a separate paraphrasing tool," and one hands-on comparison describes its rewording as more of a "convenience shortcut than a core capability."

What Grammarly offers instead are three paths to reworded text:

• Inline clarity suggestions — blue-underlined prompts to tighten wordy sentences or switch passive voice to active, available on every plan.
• Full-sentence rewrites — a Pro feature that rewrites entire sentences with generative AI.
• The sidebar Paraphraser and Humanizer — AI tools that rewrite text in a different tone, letting you pick voices like "streamlined," "creative," or "the scholar," or build a custom voice from your own writing samples.

The third path is the closest thing to a true rewording tool. A Carleton College hands-on review found the Paraphraser and Humanizer "do essentially the same thing: rewrite text in a different tone" — to the point the reviewer called them a redundant pair, since the Paraphraser even includes its own "humanize" option.

Now the honest part: what each path costs. Free accounts get basic grammar and spelling checks plus roughly 100 AI prompts per month. Full-sentence rewrites sit behind Grammarly Pro, which runs about $12 per member per month on annual billing or $30 month-to-month, with roughly 2,000 AI prompts monthly, according to pricing comparisons. The free tier also has friction beyond the paywall: the Carleton review found that over half of all suggestions are locked behind advertisements for Grammarly Pro.

Two expectations worth setting before you invest time. First, Grammarly's rewording output "tends toward the formal and cautious" and works best on formal, patterned writing — it weakens noticeably on creative or complex passages, where longer sentences make it harder for the AI to judge context. Second, treat it as a filter rather than a rulebook: accept suggestions selectively and check that any rewritten sentence still fits the surrounding paragraph, or the result can sound disjointed.

If you find yourself pairing Grammarly's editing with a separate rewording tool — a workflow many users already recommend — that's where agent skills come in. SkillzBench is building a free directory of vetted agent skills plus a free MCP connector, so you can automate the repetitive parts of your editing pipeline rather than clicking through it manually. The waitlist is live if you want to be first through the door.

The Three Rewording Paths, Ranked by When to Use Each

Grammarly gives you three distinct ways to reword text, and picking the wrong one wastes time. After hands-on testing documented by reviewers, the fastest wins come from matching each path to the problem in front of you.

Path 1: Inline suggestions for mechanical fixes. As you type, Grammarly underlines issues in color-coded text: red for grammar and spelling, blue for clarity, green for word choice, and purple for tone. Click any underline to see a suggested fix, often a quick rephrase that tightens passive voice or trims wordiness. This path requires no plan upgrade and works in real time across the editor. One tester found the performance score jumped from 61 to 80 after fixing only the red-underlined grammatical errors.

• Red underlines: grammar and spelling corrections — accept these almost always.
• Blue underlines: clarity fixes like splitting run-on sentences or converting passive to active voice.
• Green underlines: synonym and word-choice suggestions — apply judgment, since alternatives can shift meaning.
• Purple underlines: tone and delivery adjustments, useful for matching audience expectations.

Path 2: Full-sentence rewrites for wordy passages. When a whole sentence needs restructuring rather than a word swap, Grammarly's full-sentence rewrites are "where the AI can shine," according to one reviewer with 15+ years of writing experience. The catch: this feature requires Grammarly Pro at roughly $12 per month on annual billing, and free users get only about 100 AI prompts per month. Always check that a rewrite fits the surrounding paragraph — a technically better sentence can still sound disjointed in context.

Path 3: The sidebar Paraphraser for voice control. Open the sidebar and the Paraphraser rewrites text paragraph by paragraph, delivering suggestions one at a time. You can select preset voices like "streamlined," "creative," or "the scholar," or build a custom voice preset from examples of your own writing — the closest Grammarly gets to a dedicated rewording tool, since no standalone paraphrasing product exists in the suite.

Know where each path breaks down. Testing shows Grammarly's AI tools perform best on formal, patterned writing like reports and emails, and weaken noticeably on creative or complex passages — the more intricate the sentence and context, the harder it is for the AI to make the right call. Treat the tool as a filter, not a rulebook: accept suggestions selectively and verify each one before it ships.

If you want to automate the editing and rewording workflow beyond what Grammarly offers, agent skills can handle the repetitive steps — browse and test free ones on SkillzBench's directory, where every skill gets security-scanned and benchmarked for measurable Lift.

Step-by-Step Walkthrough: From Draft to Reworded Text

Once your draft is in front of you, the actual rewording process moves fast — most users get productive in under 10 minutes, according to one hands-on review. Here is how the documented workflow plays out, based on Carleton College's independent testing of the tool.

Start by writing or pasting your text into the editor. Grammarly immediately underlines potential issues using a color-coded system: red for spelling and grammar, blue for clarity, green for word choice, and purple for tone and delivery, as documented in a side-by-side comparison. Work through the underlined suggestions first — these mechanical fixes are where Grammarly's engine is strongest.

Next, open the sidebar. On the website, documents come in two modes: default, where the sidebar exclusively houses the AI writing tools, and classic, which splits into three tabs for suggestions, generative writing, and detectors. Fill in the fields for the Paraphraser or Humanizer, then choose a voice — "streamlined," "creative," or "the scholar" — or build a custom voice preset from examples of your own writing.

The critical habit at this stage: approve or discard each AI suggestion one at a time, paragraph by paragraph. Never bulk-accept. As one experienced reviewer puts it, judging whether a rewrite actually improves on your original requires skill — check that each new sentence still fits its paragraph context, or the result "may sound disjointed." This matters especially because Grammarly's output "tends toward the formal and cautious" and can feel repetitive across longer passages.

That discipline connects to the single most useful principle for this tool: treat Grammarly as a filter, not a rulebook. As one professional content strategist found, "the moment you start accepting everything blindly, it stops helping and starts getting in the way." The tool works best as a safety net for editing existing drafts, not as a ghostwriter.

It also helps to know where rewording succeeds and where it stalls:

• Formal, patterned, or rote writing — where the AI is at its best, per Carleton's testing.
• Short, isolated sentences — handled adequately, though longer passages fall short.
• Creative or complex passages — the more context a sentence carries, the harder it is for the AI to make the right call.

Note the free-versus-Pro boundary before you start: full-sentence rewrites require the Pro plan at roughly $12 per month on annual billing, while free accounts get basic grammar checking plus about 100 AI prompts per month. Carleton's reviewer also found that over half of all suggestions in the free version are locked behind Pro prompts — so expect some upsell friction mid-workflow.

If you find yourself running this edit-and-reword cycle regularly, it is worth knowing that agent skills can automate much of the surrounding workflow. SkillzBench is building a free directory where you can browse, security-scan, and benchmark those skills — the waitlist is live if you want to follow along.

Where Grammarly Falls Short — and How to Fill the Gaps

Grammarly's rewording works well enough for a sentence here and there — but push it harder and the cracks show fast. Knowing where it breaks down helps you build a workflow that actually holds up.

The most consistent complaint from hands-on reviewers is tone. Grammarly's paraphrasing output tends toward the formal and cautious, prioritizing correctness over variety, which can feel repetitive across longer passages. It works adequately for short, isolated sentences but falls short when you reword whole sections. Other testers note that paraphrased sentences can sometimes sound unnatural, and the more complex the sentence and its context, the harder the AI finds it to make the right call.

There's also a pattern-limit worth flagging. Carleton College's testing found Grammarly's AI tools are at their best with patterned, homogenous writing — status updates, rote formal prose — and much weaker on creative or nuanced passages. And the free tier constrains experimentation: over half of suggestions sit behind Pro ads, and full-sentence rewrites require the Pro plan at roughly $12/month billed annually.

So where does this leave you? Most experienced users don't fight these limits — they route around them. Community discussions frequently recommend running both tools together, using Grammarly to edit and a dedicated paraphraser to reword. The split makes sense: Grammarly's grammar engine is widely called the most sophisticated in its category, while paraphrasing remains, as one reviewer put it, a convenience shortcut rather than a core capability.

The practical gaps to plan around:

• Formal, repetitive tone on longer passages
• Unnatural-sounding rewrites on complex sentences
• Weak performance on creative or non-patterned writing
• Full-sentence rewrites locked behind the Pro tier

The natural next step is automating that two-tool workflow instead of running it by hand. Agent skills — instruction packages that tell coding and chat agents like Claude Code, Cursor, or Gemini CLI how to handle editing and rewriting tasks — can chain these steps together. The catch is trust: published research found roughly 26% of skills carry at least one vulnerability, and almost nothing tells you which skills genuinely improve output.

That's the problem SkillzBench is built to solve. Its free directory and MCP connector — currently in pre-launch with a waitlist live — will pin every skill to a version, security-scan it, and benchmark it in a sandbox, publishing the Lift in percentage points so you can see exactly what each skill adds. If editing and rewriting are part of your regular workflow, that's the way to go further than any single tool takes you.
