Quick Answer: The best AI writing tool overall in 2026 is Grammarly, now built by a company called Superhuman after an October 2025 rebrand, thanks to a genuinely useful free tier and the widest browser and app integration of any tool in this comparison, with Pro at $12/month (annual billing). Jasper is the best choice for marketing teams that need on-brand, long-form content at scale, though it’s the most expensive option here at $59-$69/month with no free plan. QuillBot is the best budget pick specifically for paraphrasing and rewriting, with a genuinely useful free tier and Premium at roughly $4.17-$8.33/month depending on billing term. Copy.ai has repositioned itself as a GTM (go-to-market) automation platform rather than a pure writing tool, starting at $29/month for its Chat plan.
Key Takeaways
- Grammarly’s parent company renamed itself from Grammarly to Superhuman on October 29, 2025, after acquiring the Superhuman email client and Coda — the writing product you use is still called Grammarly.
- Grammarly folded its old Premium and Business plans into a single Pro tier that supports up to 149 seats, priced at $12/month annually or $30/month month-to-month.
- Jasper discontinued its Creator plan on its official pricing page in 2026, now centering on just Pro ($59-69/month, one seat) and custom-quoted Business plans reportedly starting around $900/month for small teams.
- QuillBot is the clear budget leader for paraphrasing specifically, with Premium running as low as $4.17-$8.33/month on annual billing, though its core strength is rewriting existing text rather than generating new long-form content.
- Copy.ai no longer positions itself primarily as a writing tool — its current pricing and feature set are built around sales and marketing workflow automation, which matters if you were expecting a straightforward content generator.
- Grammarly and QuillBot both train their AI models on your writing by default on personal accounts, with an opt-out available; business and education tiers are typically excluded automatically.
Best AI Writing Tools 2026: Quick Comparison
| Tool | Best For | Starting Price | Free Plan |
|---|---|---|---|
| Grammarly | Overall / grammar + integrations | $12/mo (Pro, annual) | Yes — genuinely useful |
| Jasper | Long-form marketing content | $59/mo (Pro, annual) | No (7-day trial) |
| QuillBot | Paraphrasing on a budget | $4.17-$8.33/mo (Premium, annual) | Yes — generous |
| Copy.ai | Sales/marketing automation | $24/mo (Chat, annual) | No |
These four tools solve genuinely different problems, even though they’re often grouped together as “AI writing tools.” Here’s how each one actually works in 2026.
Grammarly: Best Overall
Grammarly remains the most widely used writing assistant, and its 2026 lineup is simpler than in past years after the company folded its separate Premium and Business plans into a single Pro tier.
Grammarly’s rebrand and plan structure
In July 2025, Grammarly acquired the email client Superhuman, having already agreed to acquire the collaborative document tool Coda. On October 29, 2025, the parent company renamed itself from Grammarly to Superhuman — a corporate rebrand only; the writing product everyone uses is still called Grammarly. On the product side, Grammarly Free remains genuinely useful, covering core grammar, spelling, and punctuation checks plus 100 AI prompts per month across the browser extension, desktop app, and phone keyboard. Grammarly Pro, which replaced both the old Premium and Business plans and supports up to 149 seats, costs $12/month billed annually ($144/year) or $30/month billed monthly — a steep 60% premium for not committing annually. Pro adds full-sentence rewrites, tone adjustment, plagiarism and AI-text detection, and a much larger 2,000 AI prompts per month, along with light team features like style guides and brand tones. Above Pro sits a Business tier built around the new Superhuman suite at roughly $33/month (annual), and a custom-quoted Enterprise tier.
Grammarly pros and cons
- Pros: Free tier is genuinely usable long-term, not just a trial; works everywhere via browser extension, desktop app, and phone keyboard; simplified single Pro tier replaces the old Premium/Business confusion.
- Cons: Monthly billing costs 2.5x the annual rate; style guides and brand tone consistency features are less deep than Jasper’s dedicated marketing tools; recent corporate rebrand to Superhuman can cause confusion about which company you’re actually paying.
Jasper: Best for Marketing Teams
Jasper has positioned itself as a full marketing content hub rather than a general writing assistant, with pricing to match — it’s the most expensive tool in this comparison by a wide margin.
Jasper’s simplified 2026 lineup
Jasper discontinued its earlier Creator tier on its official pricing page, now centering on two plans: Pro and Business. Pro costs $69/month billed monthly or $59/month billed annually, but it’s strictly limited to one user seat — there’s no team sharing at this tier, so a 3-person team would need three separate $59-69/month subscriptions with no shared brand voice between them. Business uses custom pricing based on team size and reportedly starts around $900/month for 3-5 users based on industry reports, since Jasper doesn’t publish standard Business rates. Business adds API access, deep CRM integrations (Salesforce, HubSpot), SSO, role-based permissions, and a dedicated account manager. Neither plan offers a permanent free tier — Jasper provides a 7-day free trial that requires a credit card to start.
Jasper pros and cons
- Pros: Deepest brand-voice and style-guide tooling for teams that need consistent on-brand output, unlimited word generation under a fair-use policy, strong SEO-mode features for content that needs to rank.
- Cons: No free plan, Pro is limited to a single seat with no team sharing, and Business pricing is opaque and reportedly starts in the hundreds of dollars per month.
QuillBot: Best Budget Pick for Paraphrasing
QuillBot occupies a different niche than Grammarly or Jasper: it’s built primarily around refining and rewriting text you’ve already written, rather than generating new long-form content from scratch, and its pricing reflects that narrower focus.
QuillBot’s plans
QuillBot’s free plan includes the core paraphraser (capped at 125 words per rewrite) with two modes, a grammar checker with a daily check limit, and a summarizer capped at 1,200 words of input. Premium removes those caps and adds unlimited paraphrasing length, all paraphrasing modes, an AI detector, an AI humanizer, and the plagiarism checker (which isn’t available at all on the free tier). Premium pricing varies significantly by billing term: $19.95/month billed monthly, $13.31/month on a semi-annual plan, or as low as $4.17-$8.33/month on annual billing depending on current promotions — QuillBot runs frequent, market-specific discounts, so the exact annual rate is worth double-checking at checkout. A Team plan for businesses and schools is priced separately per seat, and verified students can access Premium features at a further discount.
QuillBot pros and cons
- Pros: Cheapest premium AI writing tool in this comparison by a wide margin on annual billing, genuinely functional free tier, bundles eight tools (paraphraser, grammar checker, AI detector, plagiarism checker, humanizer, chat, translator, summarizer) in one dashboard.
- Cons: Built for refining existing text rather than generating original long-form content, promotional pricing varies by region and changes frequently, Team plan pricing isn’t published and requires a sales conversation.
Copy.ai: Now a Marketing Automation Platform
Copy.ai started as a straightforward AI copywriting tool but has since repositioned entirely around sales and marketing workflow automation, which is worth knowing if you’re comparing it expecting a Jasper-style content generator.
Copy.ai’s current plans
Copy.ai’s self-serve tier, called Chat, costs $29/month billed monthly or $24/month billed annually (a 20% saving). It’s built for small marketing teams, founders, and writers who mainly want fast drafts and ideas, without needing the platform’s deeper Workflow credits or CRM integrations. Above Chat sits a custom-quoted Enterprise tier that adds guided implementation support, full API access, bulk Workflow runs, more than 20 native integrations (including Salesforce, HubSpot, and Slack), SOC 2 Type II and GDPR compliance, and SSO.
Copy.ai pros and cons
- Pros: Strong fit for B2B teams that want AI writing connected directly to sales and marketing automation, deep native integrations at the Enterprise tier, competitive entry price for the Chat plan.
- Cons: No longer a pure writing tool, so the value proposition can feel heavy if you just want drafts without workflow automation, and no permanent free plan.
Data Privacy: Does Your Writing Train These Tools?
Since every tool in this comparison reads the full text of what you write in order to function, it’s worth understanding what happens to that text afterward, and the policies differ meaningfully between providers. Grammarly uses your content to train its models by default on personal (non-enterprise, non-education) accounts, but offers a dedicated “Product Improvement and Training” toggle in account settings that lets individual users opt out. Business, Enterprise, and education accounts are automatically excluded from AI training without needing to change any setting. QuillBot’s privacy policy, published by its parent company Learneo, states that it may use collected data, including personal data, to train its AI models, with only a conditional opt-out rather than a guaranteed one — though QuillBot’s separate Team plans do carry a genuine no-training default that applies automatically. Jasper and Copy.ai, as B2B-oriented tools sold partly on data-handling assurances, generally offer stronger default privacy postures for paid business tiers, though the exact terms are worth checking directly given how often SaaS privacy policies are updated.
A separate concern surfaced in January 2026, when a privacy research firm’s analysis of AI-powered Chrome extensions ranked Grammarly and QuillBot among the browser extensions with the most extensive data collection out of 442 examined, based on the browser permissions each requires to function (reading page content, tracking activity within tabs, and injecting scripts). The research characterized the security risk as low, but flagged that both tools’ permissions technically allow visibility into whatever text or data appears on a page where the extension is active — including work dashboards, email, and other tools open in the same browser — which is worth factoring in if you handle sensitive information regularly.
How to Choose the Right AI Writing Tool
If you write daily across email, documents, and social media and want one tool that works everywhere with minimal setup, Grammarly’s free tier is the right starting point, with Pro as a natural upgrade once you’re using its AI rewrites regularly. If you run a marketing team that needs consistent brand voice across many writers and a large volume of long-form content, Jasper’s brand-voice and style-guide tooling justifies its premium price, provided your team is large enough to make the Business tier’s per-seat economics work. If your main need is polishing and rewriting text you’ve already drafted — for school, academic writing, or general clarity — rather than generating new content, QuillBot’s paraphrasing focus and much lower price make it the better fit. And if your writing need is really a sales or marketing automation need in disguise, with AI copy as one piece of a larger workflow, Copy.ai’s current direction is built specifically for that.
If data privacy is your top priority
For sensitive or confidential writing, opt out of AI training in Grammarly’s account settings immediately after signup, and consider whether a business or education tier (which excludes training by default) is worth the upgrade even for solo use. For QuillBot, be aware that the opt-out is conditional rather than guaranteed on personal accounts, and that only Team plans carry an automatic no-training default. If your writing routinely includes confidential client or company information, a browser extension-based tool inherently has more access to your browsing context than a tool you paste text into manually, which is worth weighing regardless of which specific provider you choose.

Frequently Asked Questions
What is the best AI writing tool overall in 2026?
Grammarly remains the best overall choice for most people, thanks to a genuinely usable free tier and the widest integration across browsers, apps, and phone keyboards. Jasper is the better choice specifically for marketing teams that need consistent, on-brand long-form content at scale.
Did Grammarly change its name?
The parent company did. On October 29, 2025, Grammarly’s parent company renamed itself to Superhuman after acquiring the Superhuman email client and the Coda document tool. The writing product itself is still called Grammarly.
Is Grammarly Premium still a separate plan from Business?
No. Grammarly folded its old Premium (individual) and Business (team) plans into a single Pro tier that supports up to 149 seats, priced at $12/month on annual billing or $30/month month-to-month.
Why is Jasper so much more expensive than Grammarly?
Jasper is built specifically for marketing teams that need brand-voice consistency, campaign templates, and long-form SEO content at scale, which is a different (and more specialized) use case than Grammarly’s grammar-and-clarity focus. Jasper also doesn’t offer a free plan, only a 7-day trial, unlike Grammarly’s genuinely usable free tier.
Is QuillBot good for more than just paraphrasing?
Yes, to a degree — QuillBot bundles a grammar checker, AI detector, plagiarism checker, AI humanizer, translator, and summarizer alongside its core paraphraser. However, it’s still built around refining existing text rather than generating substantial new long-form content the way Jasper or ChatGPT can.
Is Copy.ai still a good option for simple AI copywriting?
It can be, through the Chat plan, but Copy.ai has shifted its overall positioning toward sales and marketing automation rather than pure copywriting. If you specifically want a straightforward content generator without workflow automation, Jasper or Grammarly may be a more direct fit for that narrower need.
Do any of these tools have a genuinely free plan?
Grammarly and QuillBot both offer free tiers that are usable long-term, not just time-limited trials. Jasper and Copy.ai do not offer permanent free plans, only short free trials that typically require a credit card to start.
Which tool is cheapest for occasional use?
Grammarly’s free tier or QuillBot’s free tier both cover casual, occasional writing needs at no cost. If you need a paid plan but use it lightly, QuillBot’s semi-annual or annual Premium billing is generally the cheapest paid option in this comparison, especially during one of its frequent promotional periods.
Does Grammarly train its AI on my writing?
By default, yes, on personal (non-business, non-education) accounts. Grammarly provides a “Product Improvement and Training” toggle in account settings that individual users can turn off to opt out, while business, enterprise, and education accounts are automatically excluded from training without any setting changes needed.
Is it safe to paste confidential work documents into these tools?
Exercise caution regardless of which tool you use, since all of them process the full text you provide on their servers. If you handle confidential or regulated information regularly, opt out of AI training where possible, and consider whether a business-tier plan (which typically carries stronger contractual data-handling terms) is worth the cost even for individual use.
