The problem this solves
Individuals and teams struggle with three common issues:
- “AI-sounding” content and language creeps in, even when the ideas are solid.
- Voice drifts from piece to piece, so the brand or style of writing feels uneven.
- Style guides exist, but they are vague, long, or ignored in real projects.
What the tool does
The Custom GPT analyzes your writing and builds a concise style profile that covers:
- Tone such as formal vs casual, energetic vs calm, friendly vs authoritative
- Structure such as short punchy lines vs longer explanatory paragraphs, bullets vs narrative
- Audience adaptation for clients, executives, or public readers
- Clarity preferences like sentence length, jargon tolerance, and how you explain concepts
It supports both personal voice and brand voice, so you can keep your own style for emails and posts, while also defining a company voice for marketing, support, and sales.
How it works in practice
You can start in four ways, each mapped to a common use case:
- What does this do? gets a quick walkthrough of the goal and process.
- Start the process begins the one-question-at-a-time flow to build your profile.
- Analyze just my writing style lets you paste or upload samples from emails, posts, or pages for a focused assessment.
- Brand Voice Creation prompts questions about values, audience, and desired impression, then returns a practical brand voice guide.
The assistant uses normal, human language in prompts and responses. No robotic phrasing. No “as an AI” disclaimers. It acts like a patient writing coach that can explain decisions and show live examples.
Why this is different
- Real examples, not theory. You get before-and-after sentence tweaks, plus quick rewrites in your voice.
- One question at a time. The experience is calm and focused, which means higher completion rates.
- Multi-mode friendly. Works fine with typing or voice. If you prefer to talk it out, it adapts.
- Reference-friendly. If you keep a house style file, the GPT can anchor to it, so your guide remains consistent across sessions.
- No AI-sounding fluff. The output reads like a person wrote it, because that is the point.
Quick example
You drop in two paragraphs from a recent update and a LinkedIn post. The tool notices a concise, pragmatic tone with short sentences, light enthusiasm, and frequent bulleting. It labels your default as casual-professional, recommends a 1 to 2 sentence lead for clarity, and provides a reusable checklist:
- Open with the outcome or the ask
- Keep sentences under 18 words when possible
- Prefer verbs like “show,” “explain,” “ship,” avoid filler like “leverage”
- Use bullets for three or more items
- Close with an action and a benefit
You now have a repeatable standard you can hand to a teammate or reuse next week.
Where teams use it
- Founders and solo marketers who need a voice that feels consistent across emails, landing pages, and posts
- Sales and success teams that want faster, clearer responses without losing personality
- In-house content teams that need a flexible brand voice guide that still adapts to different audiences
- Agencies standardizing client voice in onboarding, so drafts align on round one
