How I test AI presentation makers

Ten tests, the same for every tool, each graded from 1 to 5 on a fixed scale. The overall grade is their average plus my verdict, which can move it by up to one point. Every test is run by hand on an account I use, and the decks, exports, counts and screenshots behind each grade go in the full test results published with the review.

Written by Miles Foster, Owner and tester, RankDude.

Each tool gets the same three briefs: a 10-slide quarterly business review built on a supplied table of figures, a 12-slide teaching deck on the water cycle from a one-line prompt, and a 10-slide pitch deck from a supplied six-page document. Every tool also gets the same brand kit: a logo, two colours given as hex codes, one font and a .pptx template. Nothing is graded from a template gallery or a press kit.

Each review states how the account was obtained: bought at the public price, used on a free tier, or provided by the vendor. A vendor-provided account never changes a grade, and a vendor never sees a review before it is published.

How I rate

Every tool gets one score out of 5.

First, I run the same 10 tests on every tool and give each one a grade from 1 to 5. The average of the graded tests is the starting point; a test that cannot be graded is left out of it, and the review says how many tests the score is based on.

Then I add my verdict: what the tests cannot measure, such as how the tool holds up after the test weeks, how billing and cancelling work in practice, and how it compares with the others in the category. My verdict can move the score up or down by one point at most.

Every review shows how much my verdict changed the score, and why, in its scores table.

What a grade means

5Excellent
4Good
3Average
2Below average
1Poor

The final score is the average of the graded tests (ten when every test can be graded), to one decimal place, plus my verdict, which can move it by up to one point. If a test couldn't be finished properly it gets no grade, and the review says how many tests the score is based on. Some tests on a free plan are limited by deck, slide or export caps; I test them again on a paid plan when I can.

The 10 tests

1.Structure from a Prompt

Each first draft is checked for seven points: the requested slide count within one, a title slide, an agenda or opening, a logical order, one idea per slide, a conclusion or clear ask, and no repeated slides. Three decks give 21 points.

  • 5: 20 or 21 points
  • 4: 17 to 19
  • 3: 13 to 16
  • 2: 8 to 12
  • 1: under 8

2.Slide Design

All 32 slides are checked at full screen for text overflowing its box, overlapping elements, text failing WCAG AA contrast (measured with a checker), misalignment, mixed fonts, walls of text over 60 words, and blurry or unrelated images. Faults are counted and expressed per ten slides.

  • 5: under 1 fault per 10 slides
  • 4: 1 to 2.9
  • 3: 3 to 4.9
  • 2: 5 to 9.9
  • 1: 10 or more

3.Content Accuracy

Every factual claim in the water cycle deck is checked against two reference sources, and every figure in the business review is compared with the supplied table. Errors are counted, and figures, quotes or sources that appear nowhere in the brief or the references are counted as invented.

  • 5: no errors, nothing invented
  • 4: one minor error
  • 3: two or three errors
  • 2: four to six errors, or any invented figure
  • 1: seven or more errors

4.Use of a Supplied Document

Before the test I list the 15 key points of the six-page document. The tool builds the pitch deck from the uploaded file, and each point is checked: present and correct, distorted, or missing. Anything in the deck that is not in the document is counted as invented.

  • 5: 14 or 15 covered, nothing invented
  • 4: 11 to 13
  • 3: 8 to 10
  • 2: 4 to 7, or anything invented
  • 1: 3 or fewer, or the upload failed

5.Editing Control

Reorder slides, change one slide's layout, regenerate one slide, shorten a paragraph with the AI, insert a slide between two others, edit a chart's data, replace an image, add speaker notes, move an object freely, change the theme across the deck, undo the last three steps, and leave a comment for a collaborator. Each counts when done without a workaround.

  • 5: all twelve
  • 4: 10 or 11
  • 3: 7 to 9
  • 2: 4 to 6
  • 1: 3 or fewer

6.Brand & Theme Control

I add the logo, the two hex colours and the font, and import the .pptx template where the tool allows it. Every slide of the three decks is then checked for the right logo, exact colours (sampled) and font. A slide with any of them wrong counts as off-brand.

  • 5: template imported, no slide off-brand
  • 4: one or two slides off-brand
  • 3: three to five off-brand, or no template import
  • 2: six or more off-brand
  • 1: no brand control

7.Charts & Images

The business review asks for a bar chart, a line chart and a KPI panel from the supplied table. Each value is checked and each chart is tested for whether it stays an editable chart. Every image in the three decks is checked for relevance to its slide and for a stated source or licence, and AI-generated images are checked for artefacts.

  • 5: three charts correct and editable, every image relevant with a source
  • 4: charts correct, one static chart or one weak image
  • 3: one chart wrong
  • 2: two or more charts wrong, or images with no licence
  • 1: no charts

8.Export Fidelity

Each deck is exported as .pptx and opened in PowerPoint, opened or imported into Google Slides, and exported as PDF. Every slide is compared with the original for font substitution, layout shifts, text turned into images, charts flattened and lost animations or notes. Slides with any difference are counted.

  • 5: no slide changed, text and charts editable
  • 4: one or two slides changed
  • 3: three to six slides changed
  • 2: seven or more, or text flattened to images
  • 1: no .pptx export

9.Speed

The clock runs from submitting the brief, or confirming the outline when the tool asks for one, to the last slide finished and editable. Each of the three briefs is timed; the median is the grade, and failed or stalled generations are reported.

  • 5: median under 1 minute
  • 4: 1 to 1.9 minutes
  • 3: 2 to 3.9 minutes
  • 2: 4 to 9.9 minutes
  • 1: 10 minutes or longer

10.Pricing & Value

Every plan and credit pack is read from the checkout, not the marketing page. The figure graded is the monthly cost, billed yearly, of the cheapest plan that exports .pptx with no watermark or branding. Free-tier limits on decks, slides, credits and exports, and payment methods, are listed as seen at checkout.

  • 5: free, or under $10 a month
  • 4: $10 to $14.99
  • 3: $15 to $24.99
  • 2: $25 or more, or unclear credit costs
  • 1: poor value or hidden costs

Documented but not graded

Real-time collaboration, presenter mode and rehearsal tools, web-page and document output, translation, analytics on shared decks and add-ins for other office apps are checked and described in every review. When they work well they count in the written assessment, but they never add points to the overall grade.

Rules that apply to every test

  • Real use of the product on a real account, never promotional descriptions or template galleries.
  • Identical briefs, brand kit, tests, thresholds and sample sizes for every tool in the category.
  • Authorised accounts only; no password sharing, no bypassing of plan limits or bot checks.
  • Every grade has evidence: the decks and exports, a count, a screenshot or a table, in the full test results.
  • A grade changes only when a retest produces new evidence; the review records the date and the reason.

Questions about a specific grade go to the contact page. Makers can submit an AI presentation maker for testing. No AI presentation maker has been through these tests yet; every one I follow is listed on the AI presentation makers page, and reviews appear there as tests finish.
