Gamma AI Alternative
Gamma is strong for document-style cards and web-style sharing. Lumen is a source-to-deck workspace for teams that need outline control, in-workspace editing, source review, citations, presenter tools, and file delivery. Lumen's no-card 14-day trial includes AI generation and clean hybrid export. Downloads are not gated: a deck you generated stays yours to review, present, and export as PPTX, PDF, HTML, or slide images, unwatermarked, whether the trial is running, paid, or long over. Paid Lumen is what continues AI generation and AI editing, and adds publishing, sharing, collaboration, brand workflows, team controls, and higher capacity.
What is Gamma AI, and what does the Gamma app actually do?
Gamma AI turns a prompt into a finished-looking artifact very fast, and the Gamma app is broader than a deck tool — the same engine produces presentations, documents, websites, social posts and images.[1] That breadth is the product decision worth understanding before you compare anything else: Gamma is optimised for getting from an idea to something polished, across several output formats.
Its pricing is metered on AI usage and on how much you generate at once. The free tier creates up to 10 slides per prompt; the paid tiers raise that to 75, remove Gamma branding, and add better image models, custom branding, analytics, API access and custom domains as you go up.[1] Credits are the unit that matters — how much you can generate, rather than which features exist.
Where Gamma is genuinely ahead
Two things, and it is not worth pretending otherwise. Gamma has a real free tier — no card, and it includes PDF, PPTX, PNG and Google Slides export.[1] Gixo Lumen has a 14-day trial and then a paid plan, so if free is a hard requirement, Gamma wins that on the spot. And if you need a deck, a landing page and a social image from the same brief, one tool doing all three is a real convenience that a deck workspace does not replicate.
Where the two diverge
Gamma starts from a prompt. Lumen starts from your sources: you supply the documents, research or numbers, and the deck is built from them with claims traceable back to where they came from. Those are different jobs. If the content is already in your head and you want it laid out well, prompt-first is faster. If the content lives in a report someone will check you against, source-first is the one that survives the question "where did this figure come from?"
Gamma pricing, and the Made with Gamma badge
Gamma pricing is metered rather than flat. The free tier costs nothing, needs no card, and caps generation at 10 slides per prompt; paid tiers lift that to 75 and add better image models, custom branding, analytics, API access and custom domains as you climb.[1] The unit that constrains you is credits — how much you generate — rather than which features are switched on, which means the Gamma app pricing question is really “how much will I make this month?”
The other thing people look up once they have made something: the Made with Gamma badge on free-tier output. Removing Gamma branding is a paid-tier feature, so the badge goes when you upgrade rather than through a toggle on the free plan.[1] If a client-facing deck is the reason you are asking, that is a real cost to put in the comparison.
Gixo Lumen prices the other way round: a no-card 14-day trial, then a flat paid plan with no credit metering, so the bill does not move with how much you generate. Neither model wins outright. Metered is cheaper if you make three decks a year; flat is cheaper and far more predictable if decks are how your week is spent.

Why Switch from Gamma Presentations to Gixo for an Editable Slide Deck
Gamma is strong for web-style sharing. Gixo is stronger when the job is to finish an editable slide deck with grounding, citations, and delivery attached.
Keep decks grounded to source material and approved web research when needed. Gixo extracts key claims, highlights what needs verification, and surfaces citations, attribution, and trust status inside the deck viewer.
Generate presentations with 40+ slides. Unlike Gamma's card-based limits, Gixo creates full-length decks for in-depth topics, training, and executive presentations.
Choose from 20+ curated themes built for executive, startup, creative, and academic presentations. Each theme applies consistently across every slide.
Export presentations as hybrid PPTX/PDF for sharing, printing, or offline use. Exports are clean on the no-card 14-day trial and after it ends — deck download is not gated.
Edit any slide individually after generation. Change text, modify layouts, or regenerate a single slide with AI while keeping the rest of your deck intact.
Generate custom images for any slide directly within the editor. AI creates visuals that match your presentation content and chosen theme.
Get real slide decks, not document-style cards. Gixo creates traditional presentation slides that work in boardrooms, classrooms, and conferences.
Why Gixo is the stronger finished-deck workflow
The job is not to generate slides once. The job is to hand off a deck another person can actually open, review, and use.
Workflow fit
The deck starts from a consulting, finance, fundraising, sales, executive, product, or general-business workflow instead of generic slide filler.
Outline first
Structure stays reviewable before full generation, so the first pass is shaped like a real deck instead of a prompt experiment.
Editability
Theme switches, layout swaps, slide edits, and regeneration all happen after the deck exists without forcing a rebuild.
Evidence
Decks are grounded in your sources, and evidence — citations, trust checks, source review — has a built-in home in the workspace instead of being bolted on after generation.
Delivery
Speaker notes, present mode, shareable delivery, and exports stay on the same finished deck when it is time to ship.
Frequently Asked Questions
Gixo also runs inside PowerPoint
Gixo Lumen for PowerPoint is published on Microsoft AppSource: it creates, finds and inserts editable AI presentations without leaving PowerPoint. If your organisation's decks live in PowerPoint and always end up there, that removes the export step entirely — the slides arrive in the deck you already have open.
It is worth weighing against a browser-only tool. Web tools are excellent for producing something quickly and sharing a link; they become friction the moment the deliverable has to be a .pptx in the company template that four people will edit. Running in-host is the other answer to that problem, and it is the one enterprises tend to prefer because nothing leaves the environment they already govern.
A Gixo plan is required — the add-in is a delivery surface, not a separate product.
