How to turn a vague service into a one-sentence offer a stranger understands (free prompt + example)

Turn a vague service into a one-sentence offer a stranger understands in 10 minutes. Most people put this off until it's overdue — fill in the blanks below and it's ready in about 10 minutes.

When to use it

Run this before any outreach, proposal, or profile rewrite. Re-run every quarter. Budget about 10 minutes.

The fill-in text

Paste this into Claude or ChatGPT and fill in the brackets — the draft comes back in under a minute:

You are a positioning editor for one-person service businesses. Your job is to turn what I do
into an offer a stranger understands in one read.

Context about me:
- What I do: [WHAT YOU DO, IN YOUR OWN WORDS]
- Who I have actually worked with: [2-3 PAST CLIENT TYPES]
- A result I am proud of: [ONE CONCRETE RESULT, NO REVENUE FIGURES NEEDED]
- What I want more of: [THE KIND OF CLIENT OR PROJECT]

Task:
1. Write 5 one-sentence offers in the form "I help (who) (get what) (without / by / in)".
   Vary the angle: speed, certainty, specialism, done-for-you, outcome.
2. For each, give a 6-word version for a bio line.
3. Pick the strongest one and explain in two sentences why a busy buyer would prefer it.
4. List 3 proof points I should collect to back it up.

Constraints: plain English, no buzzwords, no promises about money. If any input above is
missing, ask me one question, then continue. Output using the template below.

Fill in these blanks: [WHAT YOU DO, IN YOUR OWN WORDS], [2-3 PAST CLIENT TYPES], [ONE CONCRETE RESULT, NO REVENUE FIGURES NEEDED], [THE KIND OF CLIENT OR PROJECT].

A worked example

Maya, brand designer in Lisbon, wrote "I do branding for small businesses". After the prompt: "I help independent coffee roasters get a label and shop identity people photograph, in three weeks, without a big-agency process." Bio line: "Coffee brands people photograph. Three weeks." Proof to collect: two shelf photos, one roaster quote, one before-and-after.

Make it yours

• Swap the client type until the sentence makes one specific person nod.
• If you serve two audiences, run it twice. One offer per audience.
• Paste the winning sentence at the top of your proposal template (workflow 04).
