What You Can Do with Gixo Lumen

Everything you can do with Gixo Lumen at a glance.

Source Grounding & Evidence Checks

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.

AI Slide Generation

Enter a topic and the AI creates a full deck with structured sections, data layouts, comparisons, and a consistent narrative flow across all slides.

Theme Library

Choose from 33 active themes spanning corporate, startup, creative, academic, and executive directions. Each includes typography, colors, and layout rules.

Slide Editing

Edit slide text and structured fields, swap layouts, reorder slides, regenerate selected content, and review citations before delivery.

AI Image Generation

Generate custom images for any slide using AI. Create visuals that match your presentation content and theme without needing stock photos.

Present Mode

Present directly in the browser with full-screen mode, keyboard navigation, and speaker notes. No software installation required.

Export as PPTX, PDF, HTML, and slide images. PPTX is hybrid: stable layouts become editable shapes, while complex slides preserve fidelity as images.

Frequently Asked Questions

How many slides can Gixo generate in one presentation?
Lumen supports generated decks of up to 40 slides. The selected workflow and source material guide the initial structure, and you can add, remove, or reorder slides during review.
What presentation themes are available?
Lumen currently includes 33 active themes across corporate, startup, creative, academic, executive, editorial, and data-led directions. The count comes from the live theme registry rather than a fixed marketing number.
Which presentation export formats does Lumen support?
Lumen exports PPTX, PDF, HTML, and slide images. PowerPoint export is hybrid: stable layouts become editable text and shapes, while complex slides preserve fidelity as images. Exports are clean on the active 14-day Starter trial and after it ends — deck download is not gated.
How do I edit slides after generation?
Open a slide to edit its text and structured fields, change the layout, add or replace images, or regenerate selected content. Some complex exported slides preserve fidelity as images, so Lumen does not claim that every exported object is independently editable.
Does Gixo have a present mode?
Yes. Gixo includes a full-screen presentation mode that runs directly in your browser. Use keyboard arrows or on-screen controls to navigate slides. Speaker notes are available for reference during your presentation. No software download needed.
What types of slide layouts does Gixo support?
Lumen currently supports 25 registered slide layouts, including title, content, bullets, comparisons, statistics, timelines, team, image, quote, process, and source-oriented layouts. The count comes from the live layout registry.
Can I add AI-generated images to my slides?
Yes. You can generate custom images for any slide using the built-in AI image generator. Describe the image you want, and the AI creates a visual that matches your presentation theme and content context. No external stock photo subscriptions needed.
Can I create presentations in languages other than English?
Yes. Gixo supports presentation creation in 50+ languages. You can generate slides directly in your target language or create in English and use the translation feature to convert to another language while preserving all slide layouts and formatting.
Is Lumen an AI presentation maker, an AI slide generator, or an AI PPT maker?
All three names describe the same job, and Lumen does it end to end: it plans the deck structure, generates the slides, picks a layout per slide from the live layout registry, applies one of the active themes, and exports the result. The distinction worth caring about is not the label but the scope — some tools stop at generating, while Lumen also covers editing, citation review, present mode, and file export in the same workspace.
Do I need PowerPoint or Google Slides installed to use Lumen?
No. Lumen is a standalone workspace that builds real 16:9 slides in the browser, so no host application is required to create, edit, or present a deck. PowerPoint only comes into it at export, and only if you want a .pptx file — hybrid PPTX export turns stable layouts into editable text and shapes, while complex slides preserve fidelity as images.
How long does it take to generate a presentation?
Slides are generated as one batch rather than one at a time, so deck length is not the main driver of how long it takes — a long deck and a short one are produced by the same pass. What does move the time is how much source material you supply and whether research and citation gathering are involved. The slower part of the job is your review, which is why every slide stays editable afterwards.
Can Lumen create responsive visual stories, not just slide decks?
Lumen also includes Stanza, a responsive visual-story mode that turns the same sources into a scrolling web story instead of a slide deck. Start quickly, or plan first and approve the scene plan before generation. Stanza grounds sources through the same pre-authorized search path as Lumen decks, it ships under Lumen access, and any Lumen deck can be converted into a Stanza story. Stanza composes a scrolling web story from 15 typed block kinds across 8 visual-story themes, each with its own display-and-body type pairing. Readers move through it in 3 reading flows (continuous, snap, and guided) and can switch between story, scene, and overview views. The counts come from the live Stanza registry, and existing decks and sources stay unchanged.
