Email Tone Naturalizer

Help people who struggle with business emails make drafts professional without sounding AI-generated

Problem

Many people run their outreach emails through AI before sending, but worry the tone sounds too AI-like and gets ignored. They want emails that are professional, clear, and human — not obvious machine-generated boilerplate.

Solution

Provide a lightweight tool where users paste a draft, choose a style like 'more professional', 'more conversational', or 'shorter', and get a rewrite that preserves personal voice and key information; include a checklist to avoid common AI phrasing and explain the changes.

Users

Indie developers, small-team founders, and freelancers who need to reach out to customers proactively but aren't confident in business writing.

MVP

Paste draft and choose style; call LLM to rewrite while preserving intent; highlight AI-sounding sentences with replacement suggestions; one-click copy result.

Revenue

Free tier plus subscription (by word or usage count), or a one-time desktop license.

Why now

The flood of AI-generated content has made recipients immune to 'AI-flavored' emails, making authentic tone more valuable in business communication; LLM capabilities are mature enough for an indie developer to build quickly.
