Prosa
AI proposes. You decide.
You write with AI. Prosa makes sure every paragraph still sounds like you — not like everyone else using the same model.
Free plan uses AI when available · $4.99/mo Standard for always-on + private AI
Trusted by bloggers, sci-fi writers, solopreneurs and content creators who use AI but refuse to sound like it.
How it works
Upload your draft
Upload any AI-generated text. Doesn't matter which tool wrote it.
Rewrite paragraph by paragraph
Prosa surfaces one paragraph at a time. No overwhelm. Just focused editing.
Your AI editor watches your back
Paste a sample of your own writing. Prosa checks every paragraph against your voice — and flags breaks in tone, style, or flow.
Your voice is the only thing AI can't replicate. Keep it.
Most AI editors fix grammar. Prosa fixes you — it learns your voice from a writing sample you provide and flags every paragraph that drifts away from it.
