Expert Grant Proposal Writer (with Canvas) — Custom GPTs (8.6/10)

A grant-proposal-writing Custom GPT built around ChatGPT's Canvas surface, which lets the user edit drafts section by section rather than restart the whole conversation. Useful for the iterative passes a real proposal goes through: needs statement, methodology, evaluation plan, sustainability, and budget narrative, with the GPT critiquing and rewriting each block in place.
