Free AI proposal generator options
Zoho Writer is free to use, and its AI, Zia, can create proposals from simple prompts. Proposify, Qwilr, Storydoc and Prospero have no free plan, but each offers a 14-day free trial.

Start with Zoho Writer if you want a free AI first draft. Freelancers should try Prospero or Storydoc, agencies Proposify or Qwilr, and sales teams GetAccept. If you answer RFPs every week, try Inventive AI and Arphie and compare them on your own past questions.
