2. Anthropic Releases a Claude for Nonprofits Plugin and Expands Claude Corps

Anthropic released the Claude for Nonprofits plugin, a set of skills and connectors built with about 30 nonprofit design partners. Its skills cover three areas: marketing, hiring, and board support; responsible setup, including mapping where donor, grant, and policy records live and answering staff questions about the organization’s AI use policy; and fundraising, including grant research with citations, RFP eligibility breakdowns, proposal and report drafting, and donor briefings. The plugin is free and installed automatically for nonprofits on Team and Enterprise plans. Anthropic also plans to expand Claude Corps, which is placing 1,000 early-career fellows in at least 400 U.S. nonprofits, through a partnership with the Taproot Foundation that matches nonprofits with pro bono consultants. Anthropic says more than 25,000 nonprofits use Claude and that over 75% of them have fewer than 10 seats. Source
