Benchmarks
Most AI slide comparisons rank templates. We rank what survives. Every test here feeds one source document and one identical prompt to two tools, exports both to PowerPoint, and scores what actually reached the slides — tables, figures, numbers, and the argument that holds them together. Both exported files are downloadable, so you can check our reading against the deck itself.
Beautiful.ai vs Tosea AI on the same monthly management report: KPI scorecard survival, variance traceability, management narrative and repair time. Both exported decks downloadable.
Beautiful.ai vs Tosea AI on the same Goldman Sachs IPO research note. Scores for evidence retention, executive narrative, PPTX fidelity and repair time, with both decks downloadable.
Genspark vs Tosea AI on the same eClinicalMedicine meta-analysis. The one run where Genspark needed less repair time than Tosea AI. Both exported decks are downloadable.
Genspark vs Tosea AI on the same Goldman Sachs research material. Genspark took the higher score in this run; full criteria, repair times and both exported decks are published.
Slidesgo vs Tosea AI on the same 46-page manual: template quality, source data, PowerPoint editability, pricing and the 32-minute repair gap. Both exported decks downloadable.
A hands-on Genspark vs Tosea AI test on the same 46-page manual, scored on content logic, source fidelity, PowerPoint editability, repair time and price. Both decks downloadable.
We tested Beautiful.ai and Tosea AI on the same 46-page Unitree GO1 manual. Scored results on tables, fonts, layout quality and repair time, with both PPTX files downloadable.
We gave Gamma and Tosea AI the same 46-page Unitree GO1 manual. Scored results on source tables, figures, fonts, pricing and repair time, with both PPTX files downloadable.
We tested Gamma and Tosea AI on the same Goldman Sachs IPO report. Scored results on source fidelity, charts, consulting logic and repair time, with both decks downloadable.
We ran Gamma and Tosea AI on the same cardiac amyloidosis meta-analysis. Scored results on figures, effect estimates, PPTX export and repair time, with both decks downloadable.
A benchmark is only worth reading if the losing side could have won. These runs hold everything constant except the tool, and publish the exported files so the scoring can be argued with.
Same source document
Both tools receive the identical file — no pre-summarising, no cleaned-up version for either side.
Same minimal prompt
“create a presentation for me”, with each product left at its own default aspect ratio and template flow.
Judged on the export
We score the exported PPTX opened in PowerPoint, not the polished web preview each tool shows you.
| Criterion | Weight | What we check |
|---|---|---|
| Source fidelity | 25% | Did the source tables, figures, and numbers survive the conversion? |
| Narrative logic | 25% | Does the slide order work as an actual talk, not just a summary? |
| Subject clarity | 15% | Is the subject explained well enough for the stated audience? |
| Font and export fidelity | 15% | Does the exported PPTX render and stay editable outside the browser? |
| Aspect ratio | 10% | Did the deck export at a standard presentation ratio? |
| Repair effort | 10% | Estimated hands-on editing before the deck could be delivered. |
Scores are out of 10. Slide counts and repair times read competitor first, Tosea AI second. Repair time is an estimate of hands-on editing before the deck could be delivered — it is the number that decides whether AI generation actually saved anyone an afternoon.

| Beautiful.ai vs Tosea AIThe most designed-looking deck of the three consulting runs, with no setup at all.⚠ Scored without the original report to hand, so evidence retention is judged on the exported decks alone — a looser check than the rest of the series. | 6.6/8.9 | 7 / 8 | 42m/20m | Tosea AI |

Genspark scored higher than Tosea AI on the Goldman Sachs consulting deck, and needed less repair time on the eClinicalMedicine paper. Gamma embeds its theme fonts and offers editable charts that Tosea AI does not. Beautiful.ai produces cleaner low-density layouts. Slidesgo costs less per deck than anything else here. Those results are published exactly as they came out — a benchmark that never loses is a brochure, and readers can tell the difference.
Yes. Every tool in a given scenario receives the identical source file and the identical prompt — “create a presentation for me” — with each product left at its default aspect ratio. Nothing is prompt-engineered in favour of one tool.
Six criteria: source fidelity (25%), narrative logic (25%), subject clarity (15%), font and export fidelity (15%), aspect ratio (10%), and repair effort (10%). Scores are out of 10, and every run publishes its per-criterion reasoning.
No. Genspark scored higher on the Goldman Sachs consulting deck (8.7 vs 8.6) and needed less repair time on the eClinicalMedicine research paper (30 minutes vs 32). Both results are published unchanged.
Yes. Every source document is publicly linked, and both exported PPTX files from each run are downloadable, so you can open them in PowerPoint and check the tables, figures, and fonts yourself.
Upload the report, manual, or paper you actually have to present, and see what reaches the slides.
