What started as a beta tool rapidly grew to serve over 5,000 grant writing teams, processing more than 3.5 million words monthly.
Unlike general AI writing tools, Grantboost is specifically designed for nonprofit grant writing. The platform combines AI-powered proposal generation with an intuitive workflow designed to eliminate the most time-consuming aspects of the grant writing process.
AI-Powered Grant Writing: Generates tailored grant proposals based on your organization’s details and specific grant opportunities.

ChatGPT is the world’s most widely used AI assistant. While not specifically designed for grants, its flexibility makes it a popular tool among resource-constrained nonprofits.
Custom Prompt Flexibility: ChatGPT responds to detailed instructions, allowing you to specify tone, format, and content requirements for different grant sections.
Research Assistance: Can help gather information about potential funders and summarize key requirements from grant guidelines.
Content Improvement: Excels at rewriting and refining existing content to improve clarity, persuasiveness, and alignment with funder priorities.
Brainstorming Support: Helps generate ideas for program descriptions, impact measurements, and addressing application questions from multiple angles.
24/7 Availability: Provides instant assistance whenever inspiration strikes or deadlines loom.
ChatGPT requires well-crafted prompts to produce useful grant content. You’ll need to provide detailed context about your organization and the specific grant opportunity. The quality of output depends heavily on how well you can articulate what you need.
Additionally, ChatGPT may occasionally generate inaccurate information or misunderstand complex nonprofit terminology. All content should be carefully reviewed by someone familiar with your organization and the grant requirements.
Free tier: Basic access with potential usage limits during peak times

Ethical Considerations: Designed with a focus on helpful, harmless, and honest outputs, reducing the risk of generating misleading content.
Data Analysis Support: Helps interpret program data and translate findings into compelling impact statements for grant proposals.
While Claude excels at technical writing, it may require more specific guidance for capturing your organization’s unique voice and mission. The interface is also somewhat less intuitive than ChatGPT for first-time users.
As with all AI tools, Claude’s outputs should be carefully reviewed for accuracy and alignment with your organization’s actual programs and capabilities.
Claude Free: Basic access with some usage limitations
Claude Pro: $17/month for priority access during high usage periods, higher message limits, and faster response times
Founded in 2021 as Jarvis and later rebranded, Jasper has become a leading AI platform for marketing-focused content creation. While primarily designed for marketing teams, Jasper’s emphasis on brand voice consistency makes it valuable for nonprofits wanting to maintain a cohesive narrative across all grant applications.
Brand Voice Training: Jasper can be trained on your existing content to learn and replicate your organization’s unique communication style across all grant materials.
Templates and Frameworks: Offers pre-built templates that can be adapted for common grant sections like executive summaries, program descriptions, and impact statements.

SEO Optimization: While primarily a marketing feature, this can help ensure your online grant materials and program descriptions use relevant keywords that align with funder interests.
Chrome Extension: Allows you to generate drafts or refine content directly within grant application portals or shared documents.
Jasper’s marketing focus means you’ll need to carefully adapt its features for grant writing purposes. The platform has a steeper learning curve than some alternatives, and its higher price point may be prohibitive for smaller nonprofits.
The emphasis on persuasive marketing language may need to be toned down for more formal grant applications, particularly for government or academic funders.

Project Tracking: Manage deadlines, tasks, and responsibilities across your team throughout the grant process.
Automated Deadline Reminders: Never miss application deadlines or reporting requirements with automated reminders.
Instrumentl’s comprehensive approach comes at a higher price point that may be challenging for smaller nonprofits. The platform’s robust feature set also means a steeper learning curve for new users.
While the AI writing features are promising, they’re newer additions to the platform and may not be as refined as tools focused exclusively on content generation.

Notion has a learning curve for teams not already familiar with the platform. The AI features are integrated into the broader Notion ecosystem, so you’ll need to adopt the entire platform rather than just using the AI components.
While powerful for organization and collaboration, Notion AI’s writing capabilities aren’t as specialized for grant writing as some dedicated tools like Grantboost!
Notion Basic: Free for personal use with limited features
Notion AI: $10/member/month (billed annually) or $12/member/month (billed monthly)
Team and Enterprise plans: Available with additional features for larger organizations

Grammarly stands out for its ability to not just correct errors but improve the overall quality, tone, and impact of your writing. It’s essential for creating grant proposals that impress funders in a way that doesn’t intefere with your natural writing style.
Advanced Grammar and Style Checking: Goes beyond basic spell-check to identify complex grammar issues, wordiness, passive voice, and other writing problems that could weaken your proposal.
Tone Adjustment: Analyzes and helps modify the tone of your writing to match the formality and style expected by different funders.

For very small nonprofits with limited grant activity, the structured approach may feel like overkill compared to simpler tracking methods.
The pricing starts at $29/mo and scales to $89/mo
