Gamma vs Gixo
They solve two different jobs. Gamma is excellent for fast, beautiful, web-native document-style cards you share as a link. Gixo Lumen is built for editable 16:9 slide decks with workflow-specific structure, source-grounded citations, and PPTX/PDF delivery — the kind of deck you take into a boardroom or investor meeting. Here is an honest, sourced breakdown so you can pick the right one.
The 30-second verdict
Most "vs" pages bury the answer. Here it is up front.
You want web-native cards, fast
- You share decks as a responsive link that reflows on any device
- You value design polish and speed over slide-by-slide control
- You want lightweight real-time co-editing with a team
- You're fine with a "Made with Gamma" watermark on free until you upgrade
You need a finished, editable deck to present
- You need true 16:9 slides for a boardroom, lecture, or investor meeting
- You want workflow-specific structure (consulting, finance, sales, fundraising…)
- You need claims grounded in your sources, with citations attached to the deck
- You want a no-card trial to evaluate the full product, not a one-time credit grant

Where Gamma is genuinely strong
A useful comparison says when the other tool is the better pick. Here's where we'd point you to Gamma.
Web-native, responsive sharing
Gamma's card format reflows cleanly from desktop to phone, so a link shared on mobile looks as polished as on a monitor. If your deck mostly lives as a shared URL rather than a projected slide, that's a real advantage.
Design speed and polish
Gamma is fast and produces attractive output with very little input. For a quick, good-looking artifact where slide-by-slide control isn't the priority, it's hard to beat.
Real-time collaboration today
Gamma supports live multi-person editing with visible cursors. If simultaneous co-editing is a hard requirement right now, Gamma is ahead of where Lumen is today.
Where Gixo Lumen is different
The job is not to generate slides once. The job is to finish a deck you can actually present.
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.
Lumen builds discrete 16:9 slides, so what you present and what you export to PowerPoint are the same artifact — no card-to-slide conversion that drops interactive elements.
7 workflow profiles across consulting, finance, startup, sales, executive, product, and general business decks. The deck is structured for the job — a consulting readout is shaped differently from an investor pitch.
Decks are grounded in the sources you provide, with a built-in citation, trust-check, and source-review surface for reviewers — not bolted on after generation. Bring a topic, notes, briefs, articles, or uploaded material and keep the claims traceable.
Create a finished presentation in one workspace, with outline planning, workflow-specific structure, slide editing, citations, presenter tools, and export attached to the same deck.
A 14-day free trial (no credit card) with full deck generation, rather than a one-time credit grant. Export and sharing unlock on paid Lumen.

Why teams pick Lumen for decks they have to present
One presentation workspace for teams that need a strong first pass, outline control, theme switching, citations, presenter tools, and delivery without rebuilding the deck somewhere else.
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.
