15minuteplan.ai
15minuteplan.ai is an AI-powered business plan generator that replaces weeks of manual drafting with a guided form-based workflow. You answer a few basic questions about your business—name, team size, and some financial data—and the platform uses GPT-3.5 or GPT-4 to assemble a complete, structured business plan in under 15 minutes. Instead of producing disconnected paragraphs like a general-purpose chatbot, it generates a cohesive document with linked sections, consistent assumptions, industry context, and financial projections.
The platform is designed for real-world business needs. It claims to be SBA-approved and aligned with standard bank business plan templates, making it useful for entrepreneurs seeking investor funding, applying for bank loans, or submitting a plan to a non-financial institution. The generated plans come in two tiers: a Starter Plan with 10 pages and 11 sections, and a Professional Plan with 30 pages and 18 sections using a higher-quality AI model.
After generation, users can refine the document using the "Talk To Plan" feature, which lets them describe changes in plain language and have the AI update the plan accordingly. The service also supports generating plans in multiple languages, including German, French, Spanish, Italian, Dutch, Japanese, Arabic, Swedish, Finnish, Danish, Norwegian, Hebrew, Korean, Indonesian, and Portuguese. This makes it a practical tool for global entrepreneurs, students, and business owners who need a polished plan quickly without being a writing expert.
