People ask whether ChatGPT can replace Gamma because ChatGPT seems to do everything. It can research, write, draw and talk. What it cannot do is lay out a slide. That single gap decides this comparison, and the useful answer is a sequence rather than a winner.

Two products

ChatGPT is OpenAI's assistant: web search with citations, long-form writing, code, image generation and voice, with projects for context. Our review gives it 4.7, the top score on the site.

Gamma takes an outline or a prompt and returns a presentation, a document or a webpage with theme, layout and imagery applied. Our review gives it 4.4 and warns that its free credits are a one-time allowance.

What each costs

ChatGPT, from our review: a free tier with limits that refresh; Plus at $20 a month; Go at ₹399 a month in India.

Gamma, from its pricing page: Free with 400 starter credits that do not refill, 10-card decks and the Gamma badge; Plus at $108 a year with 1,000 monthly credits and the badge removed; Pro at $216 a year with 4,000 credits and viewer analytics; Ultra at $1,080 a year with 20,000.

The cheaper subscription is Gamma's. The free tier that keeps working is ChatGPT's.

Step one: the content

A presentation fails on content more often than on design. ChatGPT searches the web with sources for the facts, reads the documents you upload for the context, drafts a narrative with a point, and writes speaker notes for each slide. Ask it for ten slides with a headline and three bullets each and you have an outline a person could present from. It will also generate the images, from the same window, within the plan's cap.

Gamma writes too, but from your sentence rather than your sources. A one-line prompt gives a competent generic deck. A pasted outline gives a specific one.

Step two: the slides

Gamma's job, and ChatGPT's gap. Paste the outline and Gamma applies a theme, chooses layouts card by card, places imagery and produces something that looks designed, then exports to PDF, PPTX, PNG or Google Slides, including on the free plan. ChatGPT can produce a basic file, but with no layout engine the output needs a slide tool before anyone sees it.

Students and first-time presenters

The pairing is strongest here. A school project researched in ChatGPT's free tier, with citations the teacher can check, pasted into Gamma's free tier, is a sourced and designed presentation for nothing. Gamma's 400 credits last a few decks; ChatGPT's limits refresh. For a student who presents every week, Gamma Plus at $108 a year is the first purchase.

Sales and recurring decks

Gamma Pro's analytics show who opened a deck and how far they read, which matters for a sales proposal and which ChatGPT cannot offer. For a sales team, Pro at $216 a year is the tier to compare against a slide editor, not against ChatGPT.

Limits that matter

ChatGPT's caps are per feature; image generation on the free tier runs out first, which matters for an image-heavy deck, and Plus raises it. Gamma's constraint is credits, and the free ones never return. Our ChatGPT review also notes that the Go tier may include ads.

India

ChatGPT's Go tier is ₹399 a month in India. Gamma bills in dollars with no rupee tier. For an Indian student, ChatGPT Go plus Gamma free is the cheapest working combination.

What our reviews flag

For Gamma: one-time free credits, less design control than PowerPoint or Figma, and a fit for simpler decks. For ChatGPT: per-feature caps, newest models reaching the paid work and coding products first, and possible ads on Go. None of these overlap, because the products do not.

Re-check before you buy

Gamma's pricing page was read on 12 October 2026; ChatGPT's figures come from our review because OpenAI's pricing page does not load for automated readers.

Who should pick which

Pick Gamma if you need a presentation on screen. It is our winner for that job.

Pick ChatGPT for the research, the narrative, the notes and the images, then hand the outline to Gamma.

For Gamma against the other deck tools see Beautiful.ai vs Gamma, Canva vs Gamma and the AI presentation maker guide. For ChatGPT against the other assistants, ChatGPT vs Claude. The ranked list is at best AI presentation tools.

Verdict: Gamma wins

Gamma wins because a presentation is a visual object and Gamma is the only one of the two that produces one. Choose ChatGPT when the problem is what to say rather than how to show it, when the deck needs facts with sources, or when the images on the slides matter more than the layout around them.

Frequently asked questions

Can ChatGPT create a PowerPoint file?+

It can draft the outline, write every slide's text and notes, generate images, and produce basic files you open in a slide editor. It has no layout engine or themes, so the result needs Gamma or PowerPoint to look designed.

How much does Gamma cost?+

Per Gamma's pricing page: Free with 400 credits that never refill and the Gamma badge; Plus at $108 a year with 1,000 credits a month and no badge; Pro at $216 a year with 4,000 credits and analytics; Ultra at $1,080 a year.

Does ChatGPT cost money?+

The free tier works with limits that refresh. Plus is $20 a month; in India the Go tier is ₹399 a month, per our review.

What is the best free way to make a presentation?+

ChatGPT's free tier for the research and outline, pasted into Gamma's free tier for the slides. Gamma's 400 credits cover a few decks before they run out; after that Plus is $108 a year.

Does Gamma use ChatGPT underneath?+

Gamma's pricing page mentions standard and Ultra-tier models without naming vendors, so we cannot confirm which model writes its text. If the quality of the writing matters, draft it in ChatGPT and paste the outline.
