Gamma alternative
The Gamma alternative that takes decks all the way to PPTX
Genspark AI Slides drafts the outline, designs every page with real charts, writes the speaker notes, and exports a deck your team can keep editing in PowerPoint.
Two ways to generate, on purpose
Some decks need to be edited by a team next week. Some need to look like a designer spent a day on every frame. Pick per deck.
Editable, structured, chart-ready
Every slide is a real layout with editable text, statistical charts rendered as actual charts, and speaker notes — built to survive the export to PPTX and the colleague who edits it after you.
Every slide a full-frame visual
Each page generated as one designed image for keynote-style visual decks — when impact matters more than editability. Available to members.
Both modes share themes, aspect ratios, version history, and per-slide AI actions like polish, simplify, and redesign.
Not everything is 16:9
Decks come out in seven aspect ratios — widescreen, classic 4:3, square, portrait 9:16 for mobile-first shares, even 21:9. The layout adapts instead of stretching, so a vertical version is a real design, not a crop.
Your old decks become templates
Upload an existing deck — .pptx, .ppt, .pdf, or Keynote .key — and AI Slides replicates its design slide-for-slide into a reusable template. The decks your company already approved become the starting point for every new one.
There's a dedicated AI presentation maker page if you want the feature tour without the comparison.
Genspark vs. Gamma at a glance
Both generate good-looking decks from a prompt. The differences show up after the first draft — in editing depth, exports, and what surrounds the deck.
| Genspark | Gamma | |
|---|---|---|
| Generation styles | Pro (editable layouts + real charts) and Creative (full-image slides) | Theme-based AI generation |
| Start from existing decks | Clones the design of uploaded .pptx, .ppt, .pdf, and Keynote files into reusable templates | Starts from prompts, pasted text, or imported docs |
| Editing | Full slide editor, per-slide AI actions, version history with restore points | Card-based editor with AI edits |
| Exports | PPTX with speaker notes, PDF, HTML | PPTX and PDF |
| Beyond presentations | Same account runs docs, spreadsheets, image and video generation, and an app builder | Docs and simple websites |
| Publishing decks as pages | Share links and HTML export | Polished built-in web publishing |

When Gamma stays the better pick
Gamma earned its reputation. Keep it if these describe you.
You publish decks as web pages
Gamma's card-based format doubles as a genuinely nice website. If your decks are mostly consumed as scrolling pages rather than presented slides, that's its home turf.
You want one tool, not a workspace
Gamma does one job with very little to learn. Genspark surrounds slides with docs, sheets, and media agents — more capable, more product.
Your team already shares Gamma themes
If your brand themes and habits live in Gamma, weigh the switching cost against what PPTX depth and deck cloning add for you.
Frequently Asked Questions
Is Genspark a good Gamma alternative?
If your decks end up in PowerPoint, boardrooms, or client hands, yes — that's the exact case AI Slides is built for: editable layouts, real charts, speaker notes, and a clean PPTX export. If your decks are really web pages in disguise, Gamma remains excellent at that. Type a real deck brief above and compare the output yourself.
Can I bring my Gamma presentations over?
Export them from Gamma as PPTX or PDF, then upload to AI Slides — it can replicate a deck's design slide-for-slide into a reusable template, so your existing decks become starting points rather than dead files.
Do the exports really stay editable?
Pro-mode decks export to PPTX as editable slides with speaker notes included. Creative-mode decks are full-frame visuals by design, so treat those as final artwork rather than editable layouts.
Can it handle long or data-heavy decks?
A single generation call produces up to 20 slides, and statistical charts are rendered as real charts rather than images. For longer decks, generate in sections and merge — version history keeps restore points along the way.
