ChatGPT by OpenAI continues to be a game-changer in content creation.

If you’ve ever felt stuck on how to start your proposal or how to phrase a tricky section, ChatGPT can provide instant suggestions. The free plan is robust enough to handle most tasks, whether you’re drafting a donor letter or a comprehensive report.


Grammarly’s free version remains a staple for anyone looking to improve the quality of their writing. It ensures your grammar is impeccable, your tone is professional, and your sentences are concise. This tool is especially useful when you’re working on tight deadlines and can’t afford to miss small but important details. Its tone-checking feature is a lifesaver when tailoring proposals to specific donors or stakeholders.

QuillBot is a must-have when you need to rewrite or reframe content. This AI tool is great for adjusting older reports or proposals to fit new guidelines or donor requirements. QuillBot’s free version allows you to paraphrase text effortlessly, helping you avoid redundancy while keeping your message clear and impactful.

Google Bard/ Gemini stands out for its ability to pull real-time data directly from the web.
