Grammarly vs GravityWrite in 2026: Writing correction vs all-in-one content production
Grammarly fixes and refines what you already write across 500,000+ apps. GravityWrite generates blogs, images, video, and social posts from a shared credit pool starting at $8/month.
Grammarly
GravityWrite- Grammarly has no content generation ceiling problem: AI prompts are capped at 100/month free and 2,000/month on Pro, but grammar and tone checking are unlimited on every plan including free.
- GravityWrite runs everything, blog posts, images, video, and social scheduling, through a single shared credit pool, so a heavy image month directly reduces how many blog posts you can generate.
- Grammarly Pro costs $12/month per member annually ($30 monthly); GravityWrite Plus costs $8/month annually ($97/year), roughly a third of the price for a completely different job.
- GravityWrite includes an AI website builder, a social media scheduler for up to 30 accounts, and 250+ content templates, none of which exist in Grammarly at any tier.
- Grammarly Enterprise adds unlimited brand tones and style guides for teams; GravityWrite has no brand-voice governance layer and no per-seat enterprise tier at all.
- GravityWrite support runs 10am to 10pm IST only, which creates real delays for teams outside that window; Grammarly's support scales with plan tier up to dedicated Enterprise support.
Grammarly and GravityWrite rarely compete for the same budget line because they solve different problems. Grammarly sits inside the apps you already use and corrects, rewrites, and tone-checks whatever you type, with a genuinely useful free tier and a Pro plan built for professionals writing across Gmail, Slack, and Google Docs. GravityWrite is a generation engine: point it at a topic and it produces a full blog post, a header image, a video clip, and a queued social post, all drawn from one monthly credit allowance starting at $8/month. One assumes you are the author and wants to make your draft better; the other assumes you want the draft written for you, along with the images and the posting schedule around it.
The tools at a glance
Grammarly
AI writing assistant for grammar, clarity, tone, and brand consistency across every platform you write on
Grammarly does not ask you to change how you write. It watches what you are already typing, in Gmail, Google Docs, Slack, LinkedIn, or any of the 500,000+ apps and sites it plugs into, and flags grammar mistakes, unclear phrasing, and tone problems as they happen. The free tier alone covers unlimited grammar and spelling correction with no character cap, which is more generous than most rivals offer even on paid plans.
Pay for Pro and the assistant gets more opinionated: full paragraph rewrites, tone adjustment toward a target register, a plagiarism scanner, and an AI content detector all become available inside the same editor. None of this replaces the act of writing. It is aimed at people who already have a draft and want it tightened, not people starting from a blank page needing the AI to invent the content.
Where Grammarly earns its price at scale is Enterprise: unlimited style guides and brand tones mean a support team of fifty writers can all get corrected toward the same voice automatically, backed by SAML SSO and data loss prevention for security review. That is a genuinely different product from the free browser extension, and the jump in seriousness shows in Grammarly's documented ROI cases, including one org that saved $210,000 in nine months.

GravityWrite
All-in-one AI platform for blogs, social media, images, and video so you stop juggling five separate tools.
GravityWrite starts from the opposite assumption: you want the content produced, not corrected. Give it a topic, a keyword, or a URL, and its AI blog writer builds a structured, SEO-oriented article with a headline and meta description already attached. Feed the same credit pool into the image generator instead and you get blog headers, YouTube thumbnails, or social graphics from a text prompt.
The catch, and it is a real one, is that every feature draws from the same monthly credit balance. The Plus plan's 500 credits translate to roughly 15 blog posts or 83 standard images, not both at full volume, so a month spent generating thumbnails is a month with fewer blog posts left. The Pro plan at $49/month raises that ceiling to 2,500 credits and unlocks Elite-tier models, 30+ languages, and a wider social scheduler.
The social media scheduler and AI website builder are what push GravityWrite past being just another blog generator. Connect accounts, let the AI suggest captions and posting times, and the Plus plan alone handles 5 accounts and 50 posts a month. Combined with 250+ specialized templates for everything from LinkedIn posts to product descriptions, it is built for someone replacing an entire stack of separate subscriptions with one.
| Feature | Plus $8/mo (billed $97/yr) | Pro $49/mo (billed $599/yr) |
|---|---|---|
| AI Credits per month | 500 | 2,500 |
| Approx. blog posts/mo | ~15 | ~70 |
| Social accounts | 5 | 30 |

| Content templates | 100+ | 200+ |

Which should you choose?
GrammarlyGravityWriteGrammarlyGravityWriteGrammarlyGravityWriteIt is tempting to frame this as budget tiers of the same category, but the products do not overlap much in practice. Grammarly assumes a human wrote the first draft and needs the AI to sharpen it; GravityWrite assumes the AI should write the first draft, and a human approves it. Teams that need both jobs done are not choosing between these two, they are running both at once, since a $97/year GravityWrite subscription and a $12/month Grammarly seat are not really competing for the same dollar.
Bottom line
Pick Grammarly if your writing volume is high but the content itself already exists in your head, you just need it cleaned up and toned correctly across every app you use. Pick GravityWrite if you would rather hand over a topic and get back a finished blog post, image set, and social queue, and you are comfortable managing a shared credit pool instead of unlimited output. Running both together is a reasonable setup for a solo content creator: GravityWrite drafts, Grammarly polishes before it goes live.
Frequently asked questions
Is Grammarly or GravityWrite better for writing blog posts from scratch?
GravityWrite is built for this specifically: its AI blog writer generates a structured, SEO-oriented article complete with headline and meta description from a topic, keyword, or URL. Grammarly has no blank-page generation feature beyond capped AI prompts (100/month free, 2,000/month Pro) and is designed to correct a draft you already wrote, not produce one from nothing.
Can I use GravityWrite's credits for both blog posts and images in the same month?
Yes, but they draw from the same shared pool, so using more credits on images leaves fewer for blog posts. The Plus plan's 500 monthly credits translate to roughly 15 blog posts or 83 standard images at full allocation, not both at those numbers simultaneously; heavy users of one feature will feel the ceiling on the other.
Does Grammarly have a free plan that is actually usable?
Yes, Grammarly's free plan includes unlimited grammar and spelling correction with no character limits, working across the browser extension, Google Docs, and Gmail. The free tier does cap AI text generation at 100 prompts per month, so heavy generation users will hit that ceiling well before the correction features become limiting.
Is GravityWrite worth it for a small agency managing multiple client accounts?
GravityWrite has no dedicated agency or per-seat enterprise tier, and its published pricing tops out at the Pro plan's 2,500 credits and 30 social accounts, which may not stretch across a large client roster. Grammarly, by contrast, has an Enterprise tier built specifically for larger teams needing brand tone consistency, though it addresses correction rather than content generation.
Which tool is cheaper for a solo content creator on a tight budget?
GravityWrite's Plus plan at $8/month billed annually ($97/year) is cheaper than Grammarly Pro at $12/month annually, but they buy different things: GravityWrite's price covers content generation across blog, image, and social formats, while Grammarly Pro covers correction, tone adjustment, and plagiarism detection on writing you already produced.
Does GravityWrite support time zones outside India for customer support?
GravityWrite's support hours run 10am to 10pm IST, which means teams in North America or Europe should expect delays outside that window. Grammarly's support scales by plan, with dedicated support available on Enterprise, making it the more predictable option for teams needing responsive help outside Indian business hours.
