Quick verdict: This comparison is a fork in philosophy. Gamma is an AI author: describe what you need and it generates the whole deck (or doc, or mini-website) as flowing, web-native cards — $9/mo billed yearly for Plus, metered in AI credits. Beautiful.ai is an AI editor: you work in real slides, and its Smart Slides auto-balance every layout as you type — $12/mo billed yearly for Pro, with unmetered AI generation. Gamma gets you from blank page to presentable draft fastest; Beautiful.ai gives traditional slide discipline and a far cleaner PowerPoint round-trip. Choose by deliverable: decks shared as links and quick docs → Gamma; decks that must survive as .pptx files in other people’s PowerPoint → Beautiful.ai. Prices checked October 14, 2026.

Transparency note: neither company’s pricing page renders its numbers cleanly in public, so every price here is cross-checked across multiple current October 2026 listings (both vendors raised prices within the last year — Gamma’s Plus was $8/mo billed yearly mid-2026 and is $9 now). Confirm the figure on the checkout screen; it takes ten seconds and defeats stale reviews, including older ones quoting us.
Round 1: How the deck gets made
Gamma starts from a prompt, an outline or an imported document and returns a structured, designed draft — text, images, layout — in about a minute. You then edit its cards conversationally. It’s the fastest blank-page killer in presentations, and the same document can publish as a web page. Beautiful.ai starts inside the craft: pick a Smart Slide (chart, timeline, comparison, quote) and it enforces design rules live — add a fourth bullet and the slide rebalances instead of overflowing. Its AI generates and assists, but you remain the author throughout.
Winner: Gamma for draft speed; Beautiful.ai for controlled, brand-safe construction. Different tools wearing the same category label.
Round 2: The meters
Gamma bills creativity by the credit: a generated deck costs ~40 credits; Plus refills 1,000/mo (enough for ~25 generated decks plus edits and images, with rollover up to double), Pro 4,000/mo, and top-ups exist ($6 per 1,500) when a big month hits. Beautiful.ai doesn’t meter generation at all on paid plans — your heaviest month costs the same $12. For teams with bursty workloads (conference season, fundraise season), unmetered is a genuine budget feature, not a footnote.
Winner: Beautiful.ai on metering philosophy; Gamma’s rollover softens the loss.
Round 3: Price and the two traps
Headline math: Gamma Plus $108/yr vs Beautiful.ai Pro $144/yr — Gamma is ~25–38% cheaper annually depending on what you count, and its free tier (400 one-time credits, no card) is a real audition. Now the traps. Beautiful.ai has no free plan, and its 14-day trial requires a card and auto-converts — user reports of surprise annual charges are persistent; use our standard rule: calendar reminder on day 10, no exceptions. Worse, its month-to-month Pro is $45/mo ($540/yr pace vs $144 annual) — monthly billing there isn’t flexibility, it’s a penalty. Gamma’s trap is subtler: the free tier’s “Made with Gamma” badge and one-time credits mean the free ride ends; budget the $9 from deck three.
Winner: Gamma on entry price and free access; Beautiful.ai punishes inattentive billing setups.
Round 4: PowerPoint reality
The decisive practical difference. Gamma is web-native: share a link and it looks superb; export to .pptx and reviewers consistently report broken text boxes and shifted elements — expect a cleanup pass, every time. Beautiful.ai was built in PowerPoint’s world: import a .pptx, edit with Smart Slides, export back with fidelity that corporate workflows accept. Neither tool works offline or offers a real mobile editor — both are web apps, both present fine from a browser.
Winner: Beautiful.ai, decisively, for any deck that must exist as a file. Gamma wins the link-shared world just as decisively.
The verdict
- Pick Gamma if your decks are pitches, explainers, internal docs and pages — shared by link, made under time pressure: Plus $9/mo billed yearly; Pro ($18) when you need custom branding, analytics and domains.
- Pick Beautiful.ai if your decks are client deliverables in .pptx, brand consistency is policed, and generation volume is bursty: Pro $12/mo billed yearly — never monthly, and set the trial reminder.
- Pick neither if your slides live inside Canva or Google Slides already and presentations are occasional — the switching cost beats the marginal gain; revisit when deck-making becomes weekly work. (Presentation generation is also riding inside the generalist assistants in our ChatGPT Plus analysis — adequate for many internal decks.)
FAQ
Is Gamma free to use?
Yes, meaningfully: 400 one-time AI credits (roughly 8–10 generated decks), no card required, with a “Made with Gamma” badge on shared output. Paid Plus ($9/mo billed yearly) removes the badge and refills 1,000 credits monthly.
Does Beautiful.ai have a free plan?
No — a 14-day trial that requires a credit card and auto-converts to paid. Treat day 10 as your decision deadline and put it in your calendar the day you sign up. Students with a .edu address get a year free, which is the one generous exception.
Which exports to PowerPoint better?
Beautiful.ai, and it’s the widest gap in this comparison: a faithful import/export round-trip versus Gamma’s export-then-clean-up reality. If your final artifact is a .pptx file someone else will present from, that single fact can decide the purchase.
Gamma vs Beautiful.ai for a freelancer’s client decks?
Beautiful.ai when clients demand files in their template world; Gamma when you present live or share links and speed wins the engagement. Many freelancers run Gamma for prospecting content and nothing else — its free-to-$9 ladder fits that job precisely.
