Understanding These Two AI Grant Writing Copilots
AI grant writing tools have matured significantly, and both Grantable and Grantboost represent the current state of the art in AI-powered proposal assistance. However, they take fundamentally different approaches to the same problem: how do you help nonprofits write better grants faster?
Grantable operates on the principle that your organization's historical knowledge is your greatest asset. By building a "Smart Content Library" from your past proposals, research, and organizational documents, Grantable's AI learns your voice, your impact stories, and your program details. When you need to write a new proposal, the AI draws from this rich context to generate drafts that feel authentically yours—not generic boilerplate. This approach rewards organizations that have been grant writing for years and have materials to leverage.
Grantboost takes the opposite approach: rather than requiring you to bring existing materials, it guides you through structured questionnaires about your organization, mission, and funding goals. You answer questions, and the AI generates tailored proposals based on your responses. This survey-based methodology is particularly accessible for organizations new to grant writing or those that prefer to start fresh rather than reorganize historical documents.
For nonprofits evaluating these tools, the choice often comes down to: Do you have a vault of past proposals worth mining? Or do you prefer a guided, from-scratch approach? Both deliver substantial time savings—Grantable claims 3x faster proposals, while Grantboost serves 5,000+ teams processing millions of words monthly. The question is which workflow matches how your team actually operates.
What Is Grantable?
Grantable is an AI-powered grant writing platform that positions itself as a "central hub for your entire grant-seeking operation." Founded with the mission of democratizing access to grants, the bootstrapped company has maintained independence to offer powerful tools at accessible prices for organizations of all sizes.
The platform's core innovation is its Smart Content Library—an intelligent repository that doesn't just store your documents but learns from them. When you upload past proposals, organizational research, and program descriptions, Grantable's AI categorizes and indexes this content, allowing it to pull the most relevant information when generating new proposals. The system learns your organization's unique voice and impact stories, ensuring proposals feel authentic rather than AI-generic.

Grantable is a bootstrapped company that explicitly states its mission to "democratize access to grants" by maintaining affordable pricing for all organizations. Their independence means they're not beholden to investors pushing for higher prices.

Grantboost's Approach
Grantboost focuses on accessibility through its generous free tier and lower Pro pricing. The platform emphasizes lowering barriers for "smaller nonprofits or startups" entering grant writing.
- Annual billing: 2 months free (~17% savings)
- Generous free tier (40 boosts/month)
- Lower Pro pricing ($44.99 vs $60)
Tip for Nonprofits
If you're a larger nonprofit with significant grant volume, contact both vendors directly. While no formal nonprofit discounts are advertised, custom pricing (especially Grantable's Agency tier) may be negotiable. Mention your organization size, annual grant volume, and nonprofit status.
Ease of Use & Learning Curve
Grantable Learning Path

- • Complete organizational profile survey
- • Generate first proposal immediately
First Proposals (30-60 minutes)
- • Answer questionnaire for each proposal
- • Review and edit generated content

Bottom Line on Learning Curve
Grantboost wins on initial accessibility—you can generate your first proposal in under an hour with zero prior materials. Grantable rewards the investment—once your content library is built, output is more contextually relevant and feels more "you." For new grant writers or those without historical materials, Grantboost is easier. For established organizations willing to invest setup time, Grantable delivers compounding returns.
Integration & Compatibility
Both platforms operate primarily as standalone grant writing tools rather than integration hubs. Neither offers the extensive ecosystem connectivity you might find with broader productivity tools like Notion AI or automation platforms like Zapier vs Make.
| Integration Type | Grantable | Grantboost |
|---|---|---|
| Cloud Storage | Google Drive, Dropbox ✅ | None ❌ |
| CRM Integration | None ❌ | None ❌ |
| Grant Databases | None ❌ | None ❌ |
| Zapier/Make | None ❌ | None ❌ |
| Document Export | .docx, PDF ✅ | .docx, PDF ✅ |
| API Access | Not advertised | Not advertised |
Integration Implications for Nonprofits
If your nonprofit relies heavily on integrated workflows—syncing proposal data to your CRM, connecting to grant databases like Instrumentl or Candid, or automating follow-up tasks—neither platform is ideal. Both focus on the writing phase rather than the full grant lifecycle.
Grantable's edge: Cloud storage integration means you can import documents directly from Google Drive/Dropbox rather than downloading and re-uploading. For teams with centralized document management, this reduces friction.
