Gamma for business reports: what it does well, and where the numbers come from
Gamma is very good at making a deck look finished. The question for a monthly report is a different one: who supplied the figures, and what happens to them in November.
Gamma turns a prompt, an outline or a document into a deck, a document or a web page, fast, and it has become the default recommendation in most roundups for good reason. If you need a presentable new deck by this afternoon, it is hard to beat.
This page is for a narrower reader: someone who produces the same report every month from business data and is wondering whether Gamma can do that job. The short answer is that it can make the deck, and it was never built to be the source of the numbers on it.
A note on sourcing: Gamma’s pricing page refused my automated fetch, so the price and credit figures below come from third-party trackers that disagree with each other. Check them on Gamma’s own site. I have not built the same report in both tools and timed it.
The short version
| Quiriz | Gamma | |
|---|---|---|
| Where slide numbers come from | Computed from every row of your datasets | What you type, paste or upload; the model writes the rest |
| Bring it current next month | Refresh all, same deck, same layout | Regenerate or edit by hand |
| Where the deck lives | Your own PowerPoint or Slides file and template | Gamma’s app; export when done |
| Same metric definition everywhere | Company Context, one definition | Not applicable |
| Design from a prompt | Not our job | Gamma wins this |
| Speed to a first draft of a new deck | Plan first, then build | Gamma wins this |
| Web pages and shareable documents | Not our job | Gamma wins this |
1. A generated deck can only be as right as what you gave it
Gamma writes slides from the material in front of it. Give it a document with figures in it and it will restate them, usually well. Give it a prompt asking for a quarterly summary and it will write a plausible one. In both cases the figure on the slide is something you typed or something a model produced, and the deck cannot tell you which, or whether it was the right column.
I could not find Gamma’s documentation describing a path from a spreadsheet to a computed figure: a sum across eleven exports, your definition of net sales, a join between orders and ad spend. If that exists, it was not where I looked, and I would check before relying on it either way.
Quiriz does the part before the slide. Each chart, table and figure is the result of a question compiled to SQL against every row of the dataset, so the number is computed rather than recalled. Totals, charts and the sentences beside them all come from the same reading of the data.
The question I learned to ask of any deck handed to me was not whether the slide looked right. It was where the number came from. A deck built from a person’s own typing can answer that: it came from the finance export, column F. A generated deck can only answer that you gave it the figure.
That is fine for a pitch, where nobody will check. It is not fine for a board update, where the one person who will check is the one whose opinion matters, and where the number that looks slightly off is the one that gets traced back to you.
2. The deck that goes out every month
A one-off deck is a creation task, and Gamma is built for it. A monthly deck is an update task: the structure is settled, the slides are the same, and the work is new numbers in the same shapes. Generating a fresh deck each month from a prompt gives you a slightly different structure each time, plus the original problem of getting this month’s figures into it. Credit-based plans also meter regeneration: trackers put paid allowances at roughly 1,000 to 4,000 credits a month, and each generation spends some.
In Quiriz the question stays attached to each object on the slide. Next month you press Refresh all, and every chart, table, figure and takeaway is asked again and redrawn where you left it. It works in PowerPoint and Google Slides, in the layouts and theme colors of the deck you already have.
3. Your template, or Gamma’s
Gamma decks are born in Gamma’s design language and exported afterward. PowerPoint export is available, and roundups disagree about how well it holds up: some report layouts flattening and fonts being substituted, others rate it acceptable with cleanup. If your company deck has a strict master, plan for a restyle pass either way.
Quiriz does not export anything because it never leaves the file. The add-in works inside the deck, using its own layouts, and a slide it built is an ordinary slide that anyone can edit with or without the add-in.
Where Gamma genuinely wins
Gamma is better than Quiriz at everything visual. It generates a coherent design from a sentence, produces web pages and documents as well as slides, and gets a non-designer to a finished-looking first draft in minutes. Quiriz offers none of that: no design from a prompt, no stock imagery, no “make it beautiful.” If the deck is new, one-off or narrative-led, Gamma is the better purchase and you do not need us.
Using both
The clean split is by deck. Use Gamma for the pitch, the workshop and the announcement. Use Quiriz for the review that recurs. If one deck needs both, designed layout and live numbers, the workable route is to build the layout first, then have Quiriz fill and refresh the data objects inside it. I have not run that pairing end to end, so treat it as a suggestion, and note that pasting Quiriz answers into a Gamma prompt works once but loses the refresh.
Which one is right for you
Gamma alone is fine if…
- The deck is new, and you will present it once
- Design quality is most of the value
- The figures are few, and you have checked them
- You want a web page or document as well as slides
Add Quiriz if…
- The same deck goes out every month or quarter
- The numbers come from exports or connected sources
- Slide 4 must match slide 11, every time
- The deck has to live in your PowerPoint or Slides template
