Common mistake

Asking the model to "write the whole webinar" as paragraphs. You get 60 text-heavy slides nobody can present. Fix: cap slide count from length (rule of thumb: ~1 slide per 1-2 minutes of talking, fewer if demo-heavy), one idea per slide, and force speaker notes as bullets only before you open Slides.

Before you start
  • One concrete webinar topic and who it is for
  • Target length (e.g. 30 / 45 / 60 min) and live vs replay
  • Primary CTA (book call, waitlist, checkout, reply) and optional secondary CTA
  • One proof you can show (case snippet, metric, testimonial quote, or honest "I'll teach from experience")
  • Google account for Slides (or decide you will use Gamma instead and stick to it)
  • New Claude chat reserved for this project

Lock the webinar contract (no slides yet)

Define audience, promise, CTA, and proof before anything looks like a deck.

1. Go to https://claude.ai and start a **new** chat. Keep this **same chat** open through Step 4. 2. Paste the template below with your details filled in: TOPIC: [your webinar topic] AUDIENCE (one sentence — who shows up and what they already believe): [...] SINGLE TRANSFORMATION (what they can do or decide by the end): [...] PRIMARY CTA: [e.g. book a fit call / join waitlist / checkout / reply] SECONDARY CTA (optional): [... or write "none"] FORMAT: [live with Q&A / live no Q&A / replay] LENGTH (minutes): [30 / 45 / 60] 3. Immediately after the template, paste and send this instruction: "Output ONLY a **Webinar contract** as bullets: audience, one-sentence promise, primary CTA (and secondary if any), format + length, CTA ladder if more than one ask, and **non-negotiable proof** (what evidence I will show and where it comes from). Hard ban: do NOT output slide titles, slide numbers, or any deck outline. If you started writing slides, stop and output the contract only." 4. Send. Skim the reply — it should be bullets only, no numbered slide list.

The reply lists audience, one-sentence promise, primary CTA, length, and where proof lands — and there are **no** slide titles or deck outline.
Claude jumped to slide titles or a full outline. Send: "Repeat the Webinar contract only. Do not propose slides." and do not move on until it complies.

Build a minute-aware spine

Turn the contract into timed beats with jobs, emotion, and one interaction moment.

ClaudeFreeOpen Claude
Exact action

Stay in the **same Claude chat** as Step 1. 1. Paste and send this block (fill LENGTH / FORMAT from your contract): Using the Webinar contract above, build a **spine** for my exact LENGTH. I need **8–14 numbered beats**. Each beat must include: (a) clock range like 0:00–2:30, (b) one-line **purpose**, (c) one-word **emotion** tag (curiosity / relief / urgency / trust / tension). Include explicit beats for: credibility without bragging, named **framework**, proof (case / metric / quote), transition into CTA, and Q&A or async FAQ if applicable. If FORMAT is live, add **one** poll or chat prompt with when it fires. If replay, add an on-screen question people answer in comments or a worksheet. 2. Read the spine aloud — it should take under 90 seconds.

Every beat names a **job** (not generic "content section"); time ranges cover the full LENGTH; you have one interaction or replay substitute.
You see vague blocks like "middle content." Reply: "Split the middle into 3 named sub-beats with distinct jobs and separate time ranges." Keep the same chat.

Slide-level outline + speaker notes (caps enforced)

Generate a capped slide table: tight titles, skimmable bullets, bullet-only notes.

Same Claude chat. 1. Paste: "From the contract + spine above, produce a **slide outline**. **Hard cap:** about **1 slide per 1–2 minutes** of my LENGTH — state the math (e.g. 45 min → max ~30 slides, fewer if I demo live) and do not exceed the cap. **Format:** markdown **table** OR numbered list with columns: Slide # | On-screen title (≤8 words) | On-screen bullets (max 5 words each, max 5 bullets; use — if none) | Speaker notes (**bullet fragments only**, no paragraphs). Include: title, optional agenda only if LENGTH ≥ 45, sections that map to the spine, proof slide(s), recap, CTA slide, Q&A or next step. End with: **Total slide count:** N — and one line: **Longest dense section:** slides __–__." 2. Send. Scan for paragraph-shaped speaker notes — if you see them, you are not done.

Slide count respects the cap; speaker notes are bullets/fragments only; on-screen titles are short and body text is skimmable from the back of a room.
Too many slides or paragraph notes. Reply: "Cut to N slides max (name N). Convert every speaker note to bullets ≤12 words each. No paragraphs." Re-run until clean.

Sharpen open, bridges, and CTA delivery

Lock a speakable first three minutes, section bridges, and a tight CTA with objection replies.

ClaudeFreeOpen Claude
Exact action

Same Claude chat as Steps 1–3. 1. Paste: "Using my slide outline (slides 1–3 for the open), write: (a) **First 180 seconds** — word-for-word script for how I talk through slides 1–3. Use bracketed stage directions like [pause] [look at camera] [advance slide]. (b) **Three transition bridges** — one sentence each between my major sections. No cheesy clichés (no 'without further ado'). (c) **CTA block** — 30–45 seconds spoken: **one** primary ask, what happens next, and a **soft opt-out** (if not now, smallest step). (d) **Two objections** after the pitch (pick from: time, money, need to think, spouse, already have a vendor) — each gets **one** reply line. Tone: [say warm / direct / premium — pick one and match my brand]. Ban: do not reopen negotiation with 'happy to discuss anything' or vague 'let me know.'" 2. Read the opening aloud once. Time it — aim for ~3 minutes.

Opening sounds like you at ~3 minutes; CTA states **one** clear next action; objection lines acknowledge in ≤6 words then restate the ask; no mushy reopen language.
CTA is hedged ('if you're interested…'). Reply: "Rewrite CTA: one ask, one reason to act this week, zero apology stack." Keep the same chat.

Build the deck in Google Slides

Turn the outline into a real deck: one idea per slide, notes in Presenter view, readability pass.

Google SlidesFreeOpen Google Slides
Exact action

1. Open https://slides.new (or Google Drive → New → Google Slides). Name the file: `[Topic] — Webinar — [today's date]`. 2. Pick a **simple** theme: high contrast, large default fonts. Avoid busy backgrounds. 3. For **each** row in your Step 3 outline: add a slide → paste the **on-screen title** → paste only the **allowed** on-screen bullets (max 5 bullets × 5 words — trim ruthlessly). **Do not** paste full speaker-note paragraphs onto the slide. 4. Open **View → Show speaker notes** (or Presenter view). Paste the **bullet** speaker notes from Step 3 into the notes pane for that slide. 5. **Merge** any micro-slides that only exist because you over-split; cap **section dividers** to at most one per major section (skip if your deck is short). 6. Readability pass: body text **≥24pt** where possible; delete walls of text. If a slide still looks crowded, move detail to notes only. 7. Optional alternate: **Gamma** (https://gamma.app) — paste your outline and generate a first-pass deck, then still enforce one-idea-per-slide and move overflow to speaker notes. 8. Open **Presenter view** once and scroll each slide — notes should not require mid-sentence scrolling.

Slide order matches your outline; every teaching slide has speaker notes; Presenter view is usable without scrolling mid-sentence; on-screen text is lean.
Slides show paragraph blobs from Claude. Strip bullets to the outline; keep story detail in **notes only**, not on the slide face.

All done!

You now have: A rehearsal-ready webinar deck with slide titles, lean on-screen copy, speaker notes, and a practiced open, transitions, and CTA
