Any reliable free AI business plan generators?

I’m in the early planning stage of a new project and looking for tools that can help me structure a rough but reliable business plan. I’m not ready to pay for software yet, so I’m curious if anyone here has used a free AI business plan generator that was actually helpful. If you’ve used any free tools that gave decent, detailed output, what was your experience like? Not looking for promotions just honest feedback from people who’ve actually tried them. Thanks!
