Gemini in Slides vs Lumen
Compare assistance inside an existing slide workflow with a source-to-handoff presentation workspace.
Presentation workflow comparisons
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.

What you are actually choosing between
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.
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.
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.
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.
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
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.
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.
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.
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.
Text, layout swaps, slide order, regenerating one section — and whether any of that survives the export. Generation is the easy half of the job.
If claims will be checked, look for citations attached to slides and a source-review surface, not just a bibliography slide at the end.
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.
