Grammarly vs Wordtune for Nonprofits: Which AI Writing Enhancement Tool Is Right for You?

When you're crafting donor appeals, writing grant applications, or managing your nonprofit's blog, the quality of your writing directly impacts your mission's success. Poor grammar can undermine credibility, costing funding opportunities worth tens of thousands of dollars. Conversely, clear, compelling content can inspire action, secure grants, and build lasting donor relationships.

Grammarly and Wordtune represent two different philosophies in AI-powered writing assistance. Grammarly positions itself as the comprehensive writing coach—checking grammar, spelling, punctuation, clarity, tone, and even plagiarism across every sentence you write. With access to premium AI models like GPT-4, Claude, and Gemini, Grammarly Pro offers 2,000 AI prompts per month for generating, rewriting, and refining content. However, at $144/year with no nonprofit discount (the program ended in May 2024), it's a significant investment for budget-conscious organizations.

Wordtune takes a different approach, focusing on transformation rather than correction. It excels at rewriting and paraphrasing existing content, adjusting tone (formal, casual, creative), and summarizing long documents, articles, or even YouTube videos. With a 30% nonprofit discount bringing the Unlimited plan to $84/year—$60 less than Grammarly Pro—Wordtune offers compelling value for nonprofits with tight budgets. The trade-off? Wordtune lacks plagiarism detection and has less robust grammar checking than Grammarly.

In this comprehensive comparison, we'll examine pricing (including nonprofit discounts), features (grammar checking, plagiarism detection, AI summarization), ease of use, integration capabilities, and real-world use cases. By the end, you'll have a clear framework for deciding which tool—or combination of tools—best serves your nonprofit's writing needs and budget constraints.

Wordtune is an AI-powered rewriting and paraphrasing tool that transforms how you express ideas. Unlike Grammarly's focus on error correction, Wordtune excels at taking existing content and presenting it in multiple ways—formal, casual, shorter, expanded, or more creative. For nonprofits that frequently need to adjust messaging for different audiences (board members vs. donors vs. volunteers), this flexibility is invaluable.

The platform's standout feature is AI summarization. Wordtune can condense long documents, articles, web pages, and even YouTube videos into digestible summaries, saving hours of research time. The free plan offers 3 summaries per month; Unlimited plan users ($84/year with 30% nonprofit discount) get unlimited summarizations. This capability has no equivalent in Grammarly, making Wordtune uniquely valuable for nonprofits that need to digest large volumes of research, grant guidelines, or training materials quickly.

Wordtune also includes 40+ templates optimized for short-form content: social media posts, email subject lines, ad copy, and product descriptions. The AI humanization feature makes AI-generated text sound more natural and authentic, reducing the likelihood that content is flagged as AI-written—helpful if you're using tools like ChatGPT or Claude to draft content and want to add a human touch.

Wordtune's integration ecosystem is solid but more limited than Grammarly's. Browser extensions work across Chrome, Firefox, Arc, and Edge, covering most writing platforms. There's a Microsoft Word add-in available through AppSource, plus integrations with Google Docs, Gmail, Slack, and major social platforms. However, Wordtune lacks the deep CMS integrations (WordPress, Webflow) and system-wide desktop app functionality that Grammarly offers.

The big win for nonprofits: Wordtune's 30% discount for nonprofits, students, and educators brings the Unlimited plan to approximately $84/year (down from $120), making it $60 cheaper annually than Grammarly Pro. The free tier—offering 10 rewrites per day, 3 AI summaries per month, and unlimited grammar/spelling corrections—is surprisingly generous for organizations with minimal budgets.

Price comparison winner: Wordtune. With the 30% nonprofit discount, Wordtune Unlimited costs $84/year compared to Grammarly Pro's $144/year—a $60 annual savings per user. For a 5-user team, that's $300/year saved. For a 10-user team, it's $600/year. For budget-conscious nonprofits, Wordtune's pricing advantage is significant, especially when you consider that the free tier is surprisingly robust (10 rewrites/day, unlimited grammar checking).

For nonprofits with volunteers, part-time staff, or non-technical team members, ease of use can determine whether a tool gets adopted or abandoned. Here's how Grammarly and Wordtune compare for real-world users.

Winner: Wordtune. For nonprofits where ease of use and fast adoption matter more than comprehensive features, Wordtune's simpler interface and shorter learning curve make it the superior choice. Users can be productive in minutes, not weeks.
