TL;DR
Paste your messy notes into a chat model (Claude or ChatGPT), ask for a 10-slide outline built around one message, and require it to flag a “spine slide” plus two cuttable slides. Use the copy-ready prompt below. The chat model writes the outline; a dedicated tool (Gamma, Gemini in Google Slides, or your own PowerPoint template) turns it into the actual deck. The whole draft takes about 10 minutes.
The task
You have a pile of notes (bullet points, screenshots, half-formed thoughts) and a meeting in 48 hours. You need a 10-slide outline that has one clear message, slide titles a stranger can scan, and content under each slide that you can actually talk to. Most decks fail not in the design but in the outline: every slide says something interesting, but the deck does not have a point.
When AI helps — and when it does not
AI is excellent at distilling a pile of notes into a single message and a slide sequence that builds toward it. It is poor at knowing what your audience already believes, and that determines whether your message lands or feels patronising. Use AI for shape; use audience knowledge for emphasis. Never let AI invent data, customer quotes, or org-chart facts to fill an empty slide. As of June 2026, none of the major chat models can verify a number you did not give them, so any figure they “add” is a guess.
What to feed the AI
- Audience and their prior knowledge (execs, peers, customers)
- Meeting goal (decision, alignment, information, persuasion)
- One-sentence message you want the audience to leave with
- Raw notes (paste everything, including half-thoughts)
- Time slot (15 min vs 45 min changes slide count, not just speed)
- What is not up for debate, so AI does not surface it as an open question
Copy-ready prompt
Turn these notes into a PPT outline.
Audience and prior knowledge: [one line]
Meeting goal: [decision / alignment / information / persuasion]
One-sentence message: [one line]
Time slot: [minutes]
Out of scope (do not raise): [list]
Raw notes:
"""
[paste notes]
"""
Return:
1. Slide-by-slide outline (slide count = time_slot / 3, rounded down)
2. For each slide: title (under 8 words), one supporting bullet, one speaker note (under 30 words), one visual idea
3. The "spine slide" — the one slide that, if cut, breaks the message
4. Two weak slides flagged for deletion if I run short on time
5. The first 60 seconds: literal opening sentences
Do not invent numbers, customer quotes, or org-chart claims. If a slide needs data I did not provide, write [NEED: data type] in the bullet.Variant for exec audiences: “Same outline but assume the audience already knows the background — start the deck with the decision needed, not the context.”
Which model to use for the outline
Any current chat model handles this well; the differences are small and come down to taste. Facts below are as of June 2026.
| Tool | Best for the outline step | Cost (June 2026) | Notes |
|---|---|---|---|
| Claude (Sonnet 4.6 / Opus 4.7) | Tightest prose, least verbose speaker notes | Free tier; Pro $20/mo | 1M-token context handles a huge note dump in one paste |
| ChatGPT (GPT-5.5) | Fast iteration, good at restructuring | Free $0; Plus $20/mo | US Free tier shows ads since Feb 2026; ~320-page context on Plus |
| Gemini 3.1 Pro | Outline plus one-click slide generation in Google Slides | Google AI Pro $19.99/mo | 1M context; native Slides integration |
For the outline alone, Claude tends to need the least editing because it keeps speaker notes short. ChatGPT is the quickest for back-and-forth restructuring. Pick whichever you already pay for; the prompt above does the heavy lifting either way.
Outline to actual slides
The chat model gives you text. To get a .pptx or Google Slides deck, you hand that text to a slide tool. Three routes, depending on how polished the result needs to be:
- Gamma — paste the outline and it builds a designed deck in about a minute. The free plan ships with 400 one-time credits (roughly 10-15 full decks) but stamps a Gamma watermark on every slide; the Plus plan at $10/month removes the watermark and unlocks PowerPoint export. Best when you need something presentable fast and do not have a brand template. See the AI generate PPT tutorial.
- Gemini in Google Slides — open a deck, click “Help me create a slide,” and it generates editable slides that match your existing theme. As of June 2026 it produces one slide at a time (Google has announced multi-slide generation), so this fits refining an outline slide by slide rather than bulk-generating ten. Requires an eligible Google Workspace or Google AI Pro ($19.99/month) plan.
- Your own PowerPoint template — paste the outline, build the slides by hand against your company template. Slowest, but the only route that guarantees on-brand formatting and full control. Use this for anything client- or board-facing.
A reliable default: draft the outline in a chat model, generate a rough deck in Gamma to see it laid out, then rebuild the keepers in your template. The chat model is the drafting layer; the slide tool is the file layer. Do not expect either one to do both jobs well.
Recommended output structure
Numbered list of slides with title, bullet, speaker note, and visual idea. A separate “spine slide” callout, two “cut if short on time” markers, and a 60-second opening script. Speaker notes are paragraphs, not bullets. Slide bullets are for the audience, notes are for you.
How to check the output is usable
- The one-sentence message appears (or is clearly implied) on the spine slide
- Each slide can be talked to for 90 seconds without needing extra material
- Slide titles read as a coherent paragraph if you read them in order
- The two flagged “cut if short” slides really would not break the argument
- No invented quotes or numbers (everything traces to your notes or carries a
[NEED: ...]marker)
Common mistakes
- No single message. Every slide is interesting, the deck is not
- Slides with 3+ points. Audiences remember the second-to-last, not all 3
- “Context” eating the first 5 slides. Exec audiences walk away by slide 3
- Speaker notes that just repeat the bullet. Notes should expand or anchor, not echo
- Letting AI design the visuals in words (“a clean modern infographic”). That is a design hand-off, not an outline
- Trusting a slide tool to also be your fact-checker. Gamma and Gemini reformat your text; they do not verify it
FAQ
- 15 minutes: how many slides? 5-7. Each slide gets roughly 2 minutes including questions. The prompt’s
slide count = time / 3rule lands you here automatically. - Should AI write the speaker notes too? Yes, but cut them down. AI tends to be verbose; you sound natural at about 30 words per slide, not 80. Claude is the least chatty of the three models above.
- What about appendix slides? Useful for Q&A. Ask AI for 3 appendix slides covering “the questions you’ll get.”
- Can ChatGPT or Claude export a finished .pptx? Not directly as of June 2026 — they produce text. You take that text into Gamma, Google Slides, or your own PowerPoint template to get the file. Gemini is the exception: it can generate editable slides inside Google Slides.
- Free or paid for this? The outline step works on free tiers of ChatGPT, Claude, and Gemini. You only hit a paywall when you want watermark-free exports (Gamma Plus, $10/mo) or unlimited generations.
