Best AI for presentations
You have the facts written down and you want slides - a file that opens, speaker notes, and nothing invented along the way. We gave nine assistants and two deck builders the same seven-bullet memo, with 25 numbers and names in it, and asked each for the same eight slides.
People also look for this as powerpoint, ppt, slides, slide decks or pitch deck.

Why
The one deck you could present as it came back. Eight slides in the order asked, a title slide, bar charts on the month, category and region slides with the memo's numbers as the chart data, numbered cards for the products, the problems and the actions, page numbers in the footer, and speaker notes on all eight. Every one of the 25 facts is there and nothing is made up - the two lines it added (category shares, "Lisboa's orders were worth more on average") follow from the memo and the notes say so. It took ten minutes.

Why
Four and a half minutes to a designed deck - a header strip with the shop name and page number on every slide, big-number tiles for the months, categories, products and regions, numbered actions, notes on all eight, all 25 facts and nothing invented. No charts, which is the one thing Claude has that it does not. Its in-chat preview showed a file browser instead of the slides; download the file and open it.
Best speaker notes, if it lets you in

Why
The deck with the most to say. Four real charts, a section label and number on every slide, side panels for the headline figures, and speaker notes that give you talking points rather than reading the slide back - "Braga brings volume, Lisboa brings value". It left one memo fact off the slides, the 20 customers, and called the meeting a "10-minute review" on its own initiative. The catch is the free tier - it refused this brief five times over six hours with "too many people are talking to Kimi" before it took it, then built the deck in four minutes.

How we tested
One brief and one memo to ChatGPT, Claude, Gemini, Perplexity, Microsoft Copilot, DeepSeek, Grok, Qwen and Kimi on their free tiers, and the next day to the two deck builders on the Roster, Gamma and Canva. The memo is a fictional shop's quarter - revenue by month and category, top products, orders by region, two data problems, three actions - and every number in it is known, so every slide can be checked.
Every deck that came back was opened as a file, not judged from the chat. We counted slides, read the chart data, counted the slides with speaker notes, and looked for all 25 facts and for anything that was not in the memo.
Four tools returned a .pptx with all 25 facts and notes on all eight slides. Claude's has charts and a design; Grok's has a design and number tiles; Copilot's has four charts and five-word notes; Perplexity's is two text boxes per slide. Kimi's free tier was full for six hours - five refusals an hour apart - and then it returned a designed deck with four charts and the best notes of the nine, missing one fact. Gemini built an HTML canvas that exports to PowerPoint, then broke the rules - a photo of a real shop pulled from the web with a ninth "Image Sources" slide, notes typed onto the slides instead of into the notes pane, and a regional total that does not add up. DeepSeek and Qwen said they cannot make files and gave outlines. ChatGPT had used up its free data-analysis allowance and refused, and refused again the next morning after the reset - the free plan allows one attempt a day and the Excel retry took it.
The deck builders. Gamma took the brief in its Agent composer and built eight illustrated slides in four minutes, for 32 of its 400 free credits; the exported PowerPoint has every chart and drawing as a picture, its "speaker notes" as callout boxes on the slides, a Made with Gamma badge on each, and three numbers the memo does not contain. Canva's free plan has no AI chat; its Magic Design box takes 280 characters, and the Docs route that turns notes into a deck ends in a Go to Canva Pro button.
The test was run by, or under the direction of, the one person who runs this site, with AI assistance, and every output and fact-check was reviewed by them. The surrounding text was drafted with AI assistance from our own ratings and evidence, then checked and edited by the same person. If something here is wrong, tell us and we will fix it and say so.
Questions people ask
Which AI makes the best PowerPoint from my notes?
Claude, on this test - a designed deck with charts and speaker notes, every fact from the memo and nothing added, in ten minutes. Grok gets you a designed deck without charts in under five. Kimi's deck has four charts and the best notes, but its free tier turned us away five times before it built it. Copilot gives you four charts in two minutes and notes you will rewrite. Perplexity is fastest of all, nineteen seconds, and the plainest. Gamma, the deck builder, makes the prettiest slides - and a PowerPoint you cannot edit, with the notes printed on the slides.
Will they invent things?
Five of them did not add a single fact - Kimi left one out instead. Gemini did - it found a photo of a real shop on the web and put it on the deck, and wrote a total that does not match its own table. If a tool is allowed to browse while it builds, check the images and the sums.
Do I get a real file?
From Claude, Grok, Kimi, Copilot and Perplexity, yes, a .pptx that opens in PowerPoint or Google Slides. Gemini gives a canvas with an export button that also works. DeepSeek and Qwen give you text to paste in yourself - Qwen at least formats it for PowerPoint's Slides from Outline import. The free ChatGPT needs its data-analysis allowance to build a file, and ours had run out.
Should I just use Gamma or Canva instead of a chatbot?
Gamma if you want something that looks designed in four minutes and you will present from Gamma itself - its export turns every chart into a picture, puts the notes on the slide face, adds numbers of its own, and stamps a badge on every slide until you pay. Canva, not on the free plan - there is no AI chat there, the prompt box takes 280 characters, and turning a doc into a deck is a Pro feature. For a deck from your own facts, the chatbots did better.
What about speaker notes?
Ask for them and five tools put them in the notes pane, where you want them. Kimi's are the most useful - talking points, not the slide read back. Copilot's are a few words each. Gemini's and Gamma's are printed on the slide itself, which your audience will see.
