Gemini in Slides vs Lumen
Compare assistance inside an existing slide workflow with a source-to-handoff presentation workspace.
Presentation workflow comparisons
Compare the complete handoff job—not one generation prompt.
The practical question is how a deck moves from source material through outline review, editing, evidence, presentation, and export. Use the focused comparisons below to evaluate the workflow that matters to you.
Product capabilities and marketplace availability change. Read each comparison as a workflow guide, then verify vendor-specific details before buying.
Answer first
Presentation tools, by category
Presentation tools sort into four categories, and most shortlists are really a choice between the categories rather than between the products. Manual editors — PowerPoint, Google Slides, Keynote — give total control and no structure. In-editor assistants — Copilot in PowerPoint, Gemini in Slides — add generation inside the editor you already license. Design-first tools — Canva, Beautiful.ai, Tome, Pitch — optimise how the deck looks and how a team collaborates on it. Source-to-deck workspaces — Gixo Lumen — start from the report or brief the deck is built from and end at an exported file.
The fastest way to place any candidate is to ask two questions: what does it start from, and what do you leave with? A tool that starts from a prompt and ends at a shared link is a different purchase from one that starts from your own documents and ends at a PowerPoint file, however similar the two look on a feature grid. Every comparison below is grouped by that logic, and the four categories are set out in full further down the page.

Evaluation method
Use the same source pack and handoff test.
Compare outline control, source visibility, editing effort, presentation readiness, and the exported file using the same brief. Avoid scoring tools only by the first generated screenshot.
What you are actually choosing between
Four categories, not fifteen products.
Most shortlists collapse once you notice that the fifteen comparisons above describe four shapes of tool. Deciding the shape first turns a long evaluation into a short one.
PowerPoint, Google Slides, Keynote
Total control, no structure. You decide every layout, and consistency across a long deck is your job. Still the right answer when the deck is short, the design is fixed, or the file has to be native from the first keystroke.
Copilot in PowerPoint, Gemini in Slides, add-ins
AI inside the editor you already run. Excellent for improving decks that exist, because the output is native and nothing is exported. The constraint is the host: it has to be open and licensed, and generation starts from a prompt rather than from your source files.
Canva, Beautiful.ai, Tome, Pitch
Optimised for how the deck looks and how the team collaborates on it. Strong template libraries and visual polish; the question to test is what the exported file looks like when it leaves the tool, and whether the format is slides or scrolling web cards.
Gixo Lumen
Built around the material the deck comes from: upload the report, brief, or notes, review the outline, generate discrete 16:9 slides shaped by workflow, then export hybrid PowerPoint. The wedge is grounding and handoff rather than styling.
Six questions worth asking of any candidate
How to pick the best AI presentation software for your job.
There is no universal winner, so score against your own work rather than a feature grid. These six questions separate presentation tools faster than any review does.
1. Slides or web cards?
Some AI presentation tools produce scrolling documents rather than discrete 16:9 slides. Both are valid; only one projects cleanly and exports without conversion. Settle this before anything else.
2. What can it start from?
A prompt alone, or your own documents, spreadsheets, and notes? If the deck has to carry your figures, this is the difference between a usable first draft and one you fact-check line by line.
3. How much layout variety is real?
Count the distinct layouts in a generated deck rather than the number of themes advertised. One content layout repeated thirty times is a wall of bullets in a nice palette.
4. What stays editable?
Text, layout swaps, slide order, regenerating one section — and whether any of that survives the export. Generation is the easy half of the job.
5. Where does the evidence live?
If claims will be checked, look for citations attached to slides and a source-review surface, not just a bibliography slide at the end.
6. What file do you leave with?
Run one brief through every candidate and open the exported files side by side. A deck that only exists behind a link becomes a problem the moment a colleague asks for the PowerPoint.
Questions people ask before shortlisting
Frequently asked questions
What are the best presentation tools for business decks?
There is no single best one, because a business deck is not one job. If the deck must be a native file a colleague can edit and a client can open, a manual editor or a tool with real PowerPoint export is the constraint that decides it. If the deck already exists and needs improving, an in-editor assistant does that without an export step. If it must look designed and be built with a team, a design-first tool is the shorter path. If it has to carry figures out of a report, a brief, or a spreadsheet, the deciding feature is what the tool can start from — and that is the category Lumen is in. Score candidates against the deck you actually have to produce this month, not against a feature grid.
What is the difference between a presentation tool and an AI presentation maker?
A presentation tool is where the deck is authored and edited; an AI presentation maker generates a first version of one. The distinction matters less than it used to, because most editors now include generation and most generators now include an editor — so the useful question is not whether a product has AI but where the AI sits. Generation inside the editor you already use keeps everything native and starts from a prompt. A standalone maker starts from a prompt or from source material and then has to hand the result somewhere else, which is where the exported file becomes the thing to test. Generation is the easy half of the job in either case; what stays editable afterwards, and what file you leave with, is the half that decides the purchase.
