Pricing
FreemiumGrantable has no per-seat fees; each workspace has one plan that covers everyone invited. The Free plan costs $0 and allows 5 chat messages a day with limited file uploads. Plan figures below come from a third-party pricing review dated August 2026 and Grantable's own plan docs, which do not list prices, so confirm on grantable.co/pricing.
Starter is about $50 per month ($500 per year), with roughly 50 chat messages a day and unlimited file imports. Pro is about $150 per month ($1,500 per year) with roughly 200 messages a day, scheduled tasks, deep funder intelligence and the Pro model option. Pro+ adds the largest monthly AI budget and priority support, and an Agency Hub add-on at about $300 per month is listed as coming soon.
A 50% discount has been reported for organizations with an annual budget under $500K, but it is described as lasting one year and its renewal terms are unclear. Extra AI usage can be purchased on paid plans.
FreemiumClaude offers a free tier with access to Claude Sonnet and standard usage limits — ideal for individuals exploring the platform.
The Pro plan at $20/month unlocks Claude Opus (the most powerful model), 5x more usage capacity, priority access during peak hours, and the Projects feature for persistent context across conversations.
Team plans start at $25/user/month for organizations needing shared workspaces and higher usage caps. Enterprise plans with SSO, audit logs, custom data residency, and dedicated support are available at custom pricing.

Grantable Pros & Cons
Pros
- Combines prospecting, drafting and tracking in one workspace

- Fit scores come with explanations rather than a bare number
- Content library reduces rewriting across similar applications
Cons
- Plan prices and exact AI limits are not on the plan docs page and have been reported by third parties
- Capacity is defined by chat messages, so heavy agent or scanning use is hard to predict
- Nonprofit discount renewal terms are unclear
- Agency Hub for multi-client work is not yet available
- Domain confusion: grantable.com is a parked domain, the product is at grantable.co
