Get a draft that sounds like you
DoppelWriter generates a business proposal in your natural voice — not AI-sounding, not generic. Edit it, revise it, or use it as-is.
Why Not Just Use ChatGPT?
ChatGPT writes like ChatGPT. It uses words like "delve," "tapestry," and "multifaceted" at 150x the rate humans do. It sounds competent but generic — like a college intern who read too many business books.
DoppelWriter is different. It analyzes your actual writing — your sentence rhythm, your word choices, your punctuation habits, even what you never say — and builds a voice model that's uniquely yours. The result sounds like you wrote it, because your voice is in every word.
Frequently Asked Questions
What should I include in a business proposal?
An executive summary, the problem you're solving, your proposed solution, timeline, pricing, and expected outcomes. Lead with value for the client, not features about you.
How long should a business proposal be?
5-15 pages depending on complexity. Shorter is almost always better — decision-makers skim. DoppelWriter helps you be concise while sounding like your brand.
How do I write a persuasive business proposal?
Focus on the client's problem first, quantify the impact of your solution, and make the next step crystal clear. A great proposal reads like a conversation, not a legal document.
Sound like yourself, not ChatGPT.
