Gixo Lumen · comparison
SlidesGPT Alternative
SlidesGPT generates a PowerPoint from a text prompt. Gixo Lumen can do that too, but its distinctive path is source-to-deck: you give it the document, and the deck is built from what the document actually says rather than from what a model recalls about the topic.

Where prompt-to-deck is enough
Prompting is faster when there is nothing to be faithful to.
- The topic is general. An overview of a well-known subject does not need grounding in your documents.
- You have no source material. If nothing exists yet, there is nothing to ground against.
- Speed beats accuracy. Internal brainstorming, teaching examples, first-draft scaffolding.
- You will rewrite it anyway. Sometimes a rough starting shape is all you want.
Where source-grounded generation matters
- The deck contains your numbers. Prompted decks invent plausible figures; that is the failure mode that costs you a meeting.
- It is going in front of a board, client or investor. Anyone who can check will check.
- You already have the material. A report, a brief, a previous deck — the content exists and should be used.
- Claims need to be traceable. Being able to say where a figure came from is the difference between a draft and a deliverable.
- Regulated or reviewed work. Where an unverifiable claim is a real problem, not an embarrassment.
Prompt-to-deck against source-to-deck
| Prompt to deck | Source to deck | |
|---|---|---|
| Input | A topic sentence | Your document, brief or data |
| Where content comes from | Model knowledge | The material you supplied |
| Numbers | Plausible, unverified | Taken from your source |
| Best for | General topics, fast drafts | Client, board and investor work |
| Risk | Confident invented detail | Limited to what you provided |
| Export | Check their formats | Editable PPTX and PDF |
Frequently asked questions
What is SlidesGPT?
A tool that generates PowerPoint presentations from a text prompt. Checked live in August 2026 and actively maintained.
What is the difference between prompt-to-deck and source-to-deck?
Prompt-to-deck builds from what a model knows about a topic. Source-to-deck builds from a document you supply, so specifics come from your material rather than model recall.
Does Gixo Lumen work from a prompt too?
Yes. The difference is that it also takes documents as input, which is the safer path whenever the deck contains figures anyone might check.
Why do prompted decks contain wrong numbers?
Because a model asked for a deck about a topic will produce figures that look right for that topic. Without a source to draw from, plausibility is the only constraint.
Can I try Gixo Lumen without paying?
You can build decks manually from a blank deck for free and unlimited on any plan, with no export paywall. AI generation starts with a 14-day trial.

Build from the document, not from recall
Lumen generates the deck from material you supply, so the figures on the slides are the figures in your source.
