What does this automation do?

It removes the blank page. After a discovery call, you normally spend an hour or more turning scribbled notes into a proposal. Here, the transcript does the remembering, AI does the first draft in your structure and voice, and you spend your time where it matters: checking scope, price and promises.

What do you need before you start?

• A way to transcribe calls: Fireflies (free plan available), or the transcript feature in Zoom, Teams or Google Meet
• A ChatGPT account (free works)
• Optional: a Gamma account to turn the text into a polished document
• Your services, packages and prices written down

How do I set it up?

Step 1: Write your proposal building blocks once

Create a document with: your standard proposal headings, a short “about me”, your packages with prices, your standard terms (payment terms, what’s out of scope, how changes are charged), and two past proposals you were happy with. This is what makes the AI write like you rather than like everyone else.

Step 2: Set up a ChatGPT project with your services and pricing

Create a ChatGPT Project called “Proposals”. Upload the building-blocks document and paste the prompt below into the project instructions. If your plan doesn’t have Projects, keep the prompt in a note and paste it with each transcript.

Step 3: Tell the client you are recording, then record the call

Add a line to your calendar invite (“I record and transcribe calls so I can focus on you; tell me if you’d rather I didn’t”), and say it again at the start. Then let Fireflies join, or start your meeting tool’s transcript.

Step 4: Export the transcript

After the call, download or copy the transcript (in Fireflies, open the meeting and copy or download the transcript; in Zoom, Teams or Meet, find it in the recording or the meeting chat). Remove small talk and anything you agreed was off the record.

Step 5: Generate the proposal draft

Paste the transcript into a new chat inside your project with the line: “Draft the proposal for this call.” You’ll get the proposal plus a list of open questions.

Step 6: Check scope, price and promises line by line

This is the step AI can’t do for you. Confirm every deliverable was actually discussed, the timeline is realistic, the price comes from your packages, and nothing promises results you can’t control. Answer the open questions, or send them to the client.

Step 7: Turn the draft into a polished document with Gamma

In Gamma, choose Create new › Paste in text, paste the approved draft, pick “Document” (or “Presentation” for a deck) and apply your brand theme. Export as PDF or share the link. On the free plan, Gamma’s one-off credits cover several documents; after that you’ll need Plus or another tool.

Step 8 (optional): Automate the hand-off with Zapier

If you send several proposals a week, you can have Zapier create the draft automatically when a Fireflies transcript is ready (outline below). You still review it before sending.

The copy-paste prompt

You are my proposal writer. I'm [NAME], a [ROLE] helping [CLIENT TYPE] with
[OUTCOME]. Use the uploaded building blocks for my packages, prices, terms and
writing style.

From the call transcript I give you, write a proposal with these sections:
1. Your situation (their words where possible, 3-5 bullets)
2. What you want to achieve (measurable goals they stated)
3. My recommended approach (phases, each with deliverables)
4. Timeline
5. Investment: choose ONE of my packages (or a combination) and explain why
   in one sentence. Use my prices exactly. Never invent a price or discount.
6. What's not included
7. Next steps

Rules:
- British English, plain and confident, no hype, no "leverage" or "synergy".
- Only include deliverables and goals actually discussed in the call.
- Do not promise results (e.g. "will increase sales by 30%").
- After the proposal, list OPEN QUESTIONS: anything unclear or missing
  (budget, decision-maker, deadline, scope edges).

Zapier template outline (optional)

Multi-step Zaps need a paid Zapier plan (Professional from $19.99 a month billed yearly). Fireflies also connects to Make if you prefer.

What UK rules apply?

• Transparency when recording. UK GDPR requires you to tell people what personal data you collect and why. Telling clients before you record or transcribe, and explaining how long you keep recordings, covers this (ICO).
• Retention. Decide how long you keep recordings and transcripts (for example, delete 90 days after the proposal is decided) and set your tools to match.
• Confidentiality. Your NDA may restrict where client information goes. If in doubt, anonymise the transcript before pasting it into an AI tool.
• Contracts. A proposal the client signs can become your contract. Make sure payment terms and what’s out of scope are clear; for business clients, late payment law gives you extra rights (see our invoice chasing guide).

What can go wrong?

• Scope creep in writing. AI tends to include every idea mentioned in passing. Cut anything you didn’t agree to deliver.
• Generic copy. If it sounds like everyone else, your building blocks are too thin. Add past proposals and phrases you actually use.
• Wrong numbers. Check every price and total by hand.
• Recording surprises. Bots joining calls unannounced annoy clients. Always say it first.
