AI PPT Maker: Make a Presentation with ChatGPT, Gemini, Copilot or Gamma

By Ravindra Bagale, trainer · LinkedIn · Last updated: 19 October 2026

Generative AI course · Chapter 19 · Estimated reading time: 14 minutes

1. Suppose the seminar is on Monday

Suppose we are Sakshi, a T.Y. B.Com student in Satara. Our professor gives us a seminar topic on Friday: "A plastic-free campus", 8 to 10 minutes, on Monday.

We open an "AI PPT maker", type plastic-free campus and get 12 beautiful slides with stock photos of oceans and sentences like "Plastic pollution is a global crisis affecting millions." Nothing about our campus, no plan, nothing the professor can ask us about.

The better way takes 20 minutes:

1. Ask a chat AI for an outline that fits our audience and time.
2. Fix the outline with our own facts (our canteen, our bins).
3. Then turn it into slides.

2. The slide outline prompt

You are a presentation coach. Make a slide outline for a [N]-minute talk.
Topic: [topic]. Audience: [who]. Goal: after the talk, the audience should [what].
Rules:
- One idea per slide. A heading of max 6 words and 3 or 4 bullet points of max 10 words each.
- Slide count: [N] (including a title slide and a thank-you slide).
- Use my facts below. Where a fact or number is needed and I did not give it, write [check].
- After the outline, give speaker notes for each slide: 2 or 3 sentences I can say.
My facts: [your facts]

The [check] rule works like [number?] in the resume chapter: the AI shows where a fact would help, and you find the real one.

3. Worked example 1: a college seminar

Prompt (filled in):

You are a presentation coach. Make a slide outline for an 8-minute talk.
Topic: a plastic-free campus. Audience: classmates and 2 professors. Goal: they agree to a 30-day pilot.
Rules:
- One idea per slide. A heading of max 6 words and 3 or 4 bullet points of max 10 words each.
- Slide count: 7 (including a title slide and a thank-you slide).
- Use my facts below. Where a fact or number is needed and I did not give it, write [check].
- After the outline, give speaker notes for each slide: 2 or 3 sentences I can say.
My facts: our canteen uses plastic cups and spoons; the stationery counter gives plastic bags;
bins are not separated; about 2,000 students; I want a 30-day pilot with steel cups and cloth bags.

Expected output (yours will be similar, not the same):

Slide 1 – Plastic-Free Campus: A 30-Day Plan
  Seminar by Sakshi More, T.Y. B.Com

Slide 2 – The problem on our campus
  - Canteen uses single-use plastic cups and spoons
  - Plastic bags at the stationery counter
  - Bins are not separated into wet and dry

Slide 3 – Why it matters
  - Plastic waste blocks drains in the monsoon [check]
  - Cups and spoons are used once, then thrown away
  - Small daily changes add up across 2,000 students

Slide 4 – Our 30-day plan
  - Week 1: survey canteen and counters
  - Week 2: steel cups and cloth bags pilot
  - Week 3: separate bins with clear labels
  - Week 4: count waste and share results
...
Speaker notes, slide 2: "Every day in our canteen, hundreds of plastic cups are used once..."

Fix the [check] items. "Plastic waste blocks drains in the monsoon": find a source (for example, a municipal corporation notice or a news report on your city) or reword it to what you have seen yourself: "Last monsoon, the drain near our gate was blocked with plastic." Your own observation is often more powerful than a general claim.

4. Turn the outline into slides: 4 ways

ChatGPT can also create presentation files in ChatGPT Work where your plan supports it; the free plan has limited Work access on desktop. Check your account before you rely on it.

Way 1: Gamma

1. Go to gamma.app and sign up (the free plan needs no card).
2. Choose Create with AI, then the option to paste in text.
3. Paste your corrected outline (not just the topic). Choose the number of slides (up to 10 per prompt on the free plan).
4. Pick a theme, generate, and edit any slide by clicking on it.
5. Export: Share → Export → PowerPoint or PDF.

Pasting your outline gives you your content with Gamma's design. Typing only a topic gives you Gamma's content, which is the problem from section 1.

Way 2: Copilot in PowerPoint

1. Open PowerPoint with an eligible Microsoft 365 account (saved to OneDrive).
2. Open Copilot (the button is in the lower-right corner of the presentation).
3. Ask: Create a presentation from this outline: and paste the outline. You can also ask Copilot to use a Word file that holds your outline.
4. Review each slide: wording, images, order.

If Copilot does not appear, use the same checks as in the Excel chapter: lower-right corner, account that owns the plan, update the license, privacy settings.

5. Worked example 2: a sales pitch

Suppose we are Imran, a sales executive for a company that sells water purifiers to offices in Hyderabad. We need a 6-slide pitch for an office manager.

Prompt:

Make a 6-slide sales pitch outline for an office manager of a 50-person office.
Product: our office water purifier (facts below). Goal: book a free 7-day trial.
Structure: 1) their problem, 2) cost of the problem, 3) our solution, 4) proof, 5) offer, 6) next step.
Rules: one idea per slide, max 4 bullets, no claims I did not give; write [check] where proof is needed.
Facts: 3 filter stages; service visit every 3 months included; 2 offices in Hitech City use it;
monthly rental ₹1,499 including service; free 7-day trial.

Expected output, slides 4 and 5 (yours will be similar, not the same):

Slide 4 – Offices that already use it
  - 2 offices in Hitech City use our purifier
  - [check] a short quote from one office manager
  - Service visit every 3 months, included

Slide 5 – Simple monthly plan
  - ₹1,499 per month, service included
  - No large upfront cost
  - Free 7-day trial before you decide

Notice: the AI did not invent "99.9% pure" or "trusted by 500 companies". Our rule stopped it. Before the meeting, ask one of the 2 offices for a real quote and permission to use their name.

6. Worked example 3: a training deck from a PDF

Suppose we are Deepa, an HR executive in Noida. We must train new joiners on the company's 25-page leave policy (a PDF). We want a 10-slide deck and a short quiz.

Using Gemini Notebook (formerly NotebookLM):

1. Open notebook.google (the old notebooklm.google.com link redirects there) and create a new notebook.
2. Add the leave policy PDF as a source. (Use a document you are allowed to upload. For practice, use a public policy or the sample leave policy from the tool comparison chapter.)
3. In the chat, ask:

Using only this policy, make a 10-slide outline for training new joiners.
One idea per slide, max 4 bullets, simple English. Cite the section for each slide.
End with 5 quiz questions with answers, each answer with its section number.

4. Check the citations: click them to see the exact part of the PDF.
5. Optionally, use the Slide deck option in the notebook (if your account shows it) for designed slides (limited on the free plan; a visible watermark is added in India), or paste the outline into Gamma or PowerPoint.

Expected output, one slide (yours will be similar, not the same):

Slide 4 – Sick leave
  - 8 days of sick leave per year (Section 2)
  - Medical certificate needed for more than 2 days in a row (Section 2.3)
  - Inform your manager before 10 am on the day (Section 2.4)

The section numbers let you check every rule against the PDF. In HR training, a wrong rule on a slide can become a wrong rule in the whole team.

7. Bonus: make a .pptx from an outline with Python

If you make many decks in the same format (weekly reports, training sessions), a short script saves time. Ask the AI to give the outline as JSON (you learned JSON in the structured output chapter), then run this script.

Install once:

pip install python-pptx

outline.json (from the seminar example; shortened here):

{
  "title": "Plastic-Free Campus: A 30-Day Plan",
  "subtitle": "Seminar by Sakshi More, T.Y. B.Com",
  "slides": [
    {"heading": "The problem on our campus", "points": ["Canteen uses single-use plastic cups and spoons", "Plastic bags at the stationery counter", "Bins are not separated into wet and dry"]},
    {"heading": "Our 30-day plan", "points": ["Week 1: survey canteen and counters", "Week 2: steel cups and cloth bags pilot", "Week 3: separate bins with clear labels", "Week 4: count waste and share results"]}
  ]
}

make_ppt.py:

import json
from pptx import Presentation

data = json.load(open("outline.json", encoding="utf-8"))
prs = Presentation()

cover = prs.slides.add_slide(prs.slide_layouts[0])
cover.shapes.title.text = data["title"]
cover.placeholders[1].text = data["subtitle"]

for s in data["slides"]:
    slide = prs.slides.add_slide(prs.slide_layouts[1])
    slide.shapes.title.text = s["heading"]
    body = slide.placeholders[1].text_frame
    body.text = s["points"][0]
    for point in s["points"][1:]:
        body.add_paragraph().text = point

prs.save("seminar.pptx")
print(f"Saved seminar.pptx with {len(prs.slides)} slides")

Run it:

python make_ppt.py

Output (real, with the full 6-slide outline plus the title slide, run on 19 October 2026 with python-pptx 1.0.2):

Saved seminar.pptx with 7 slides

Open seminar.pptx in PowerPoint or Google Slides and apply a design (in PowerPoint, the Design tab). The content is yours; the design takes 2 minutes.

8. Speaker notes and practice

Slides are not the talk. Ask for help with the talk too:

Here is my slide outline. For each slide, write speaker notes I can say in about 1 minute,
in simple spoken English. Then list 5 questions the professor may ask, with short answers based only on my slides.

Practise once aloud with a timer. If a slide takes more than 90 seconds, cut a bullet.

9. Before you present: the check

1. Facts: every number and claim has a source or is your own observation. No [check] left.
2. Images: use images you are allowed to use (your own photos, the tool's licensed images, or free-to-use image sites). Do not copy logos or photos of other companies' products.
3. Badges and watermarks: free exports may carry a tool badge or watermark. Fine for college; check the rules for client decks.
4. One idea per slide: if a slide has 8 bullets, split it.
5. Readability: at least 24-point text, dark text on a light background (or the reverse).

10. Beginner mistakes and quick fixes

11. Try at home

Recap

Write the outline for your next presentation today, before you open any slide tool. You will finish faster, and your slides will be about you.
