DoppelWriter generates a recommendation letter 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
How do I write a strong recommendation letter?
Be specific about the person's contributions and character. One concrete example of their work is worth more than five adjectives. DoppelWriter helps you write it in your authentic voice.
How long should a recommendation letter be?
One page, or about 400-500 words. Cover your relationship, 2-3 specific strengths with examples, and a clear endorsement.
What should I include in a recommendation letter?
Your relationship to the person, specific examples of their skills or character, and a clear statement of recommendation. Avoid vague praise — details make it credible.
