Gamma PowerPoint has become the default answer to “what AI tool should I use for slides”, and for a web-first deck that lives in a browser it is a good one. The trouble starts when the deck has to leave the browser. Investors, boards and clients still ask for a PowerPoint file, and that is where a tool built around a card-style web format starts to cost you time or money, or both. In September 2026 the team at Wonderslide tested Gamma’s PowerPoint export on a real deck and compared nine alternatives on the questions that matter if you need a file at the end. Here is what a cost-conscious reader should take from it.
What Gamma PowerPoint export actually gives you
The test deck was a 10-slide business review generated in Gamma on a new account: title, agenda, big-number slide, table, bar chart, photo, icons, timeline, comparison, next steps. Exported to PowerPoint and opened in Google Slides, all ten slides kept editable text and the table stayed a real table. Gamma says tables are exported as editable tables on all plans and that it embeds the theme fonts in the file, which held up.
Two things did not. The bar chart and the four icons came through as pictures, so a number on the chart cannot be changed in PowerPoint. Before export Gamma PowerPoint warned that four of the ten slides had overflowing content, and four pages of the PDF export came out taller than standard 16:9. Generating the deck used 38 of the 400 one-time credits a new account gets, and every export on the free plan carries a “Made by Gamma” badge.
The credit and badge maths
This is where the money question lives. Four hundred credits at 38 per deck is roughly ten decks before you pay, and each of them carries the badge. Removing the badge means a paid seat at $9 a month billed yearly, which is $108 up front for a tool you may use four times a year. That is not expensive in absolute terms, but it is the wrong shape of cost for occasional use, and it is the main reason people look for an alternative.
Which alternatives solve which problem
The comparison asked four questions of each tool: is there editable PPTX export, on which plan, can you start from your own file, and what does the first paid tier cost. The full table is in the write-up on Gamma alternatives with editable PPTX export, with the data dated 16 September 2026. The short version, grouped by the problem you are trying to solve:
- You need a finished, fully editable PowerPoint from a task or your own files: Wonderslide, where every shape, text block and image in the PPTX is a separate object. It accepts PDF, DOCX, PPTX and XLSX, and sells decks one at a time at $4.99, or $7.99 for a week and $12.99 for a month. The free tier is three decks a month, PDF only.
- You want strict, consistent layouts across a team: Beautiful.ai, with editable PPTX on paid plans and a 14-day trial, from $14.50 a month billed yearly.
- You collaborate on decks in real time: Pitch, with PPTX import on all plans but export only from the Plus tier, €10 a month billed yearly.
- You never want to leave Microsoft or Google: Copilot in PowerPoint ($9.99 a month with Microsoft 365 Personal) or Plus AI for Google Slides and PowerPoint ($10 a month billed yearly, 7-day trial).
- You want something visual and social-style: Canva, with PowerPoint download and 20 free AI uses, $12 a month billed yearly.
Presentations.ai, Decktopus and SlidesAI round out the list; all three start from a text prompt rather than your own file, and only Presentations.ai offers editable PPTX on every plan.
Reading the price lists honestly
Six of the nine alternatives, including Wonderslide, have no permanent free plan with PPTX export. The useful comparison is therefore not free versus paid but the shape of the paid tier. Annual seats suit people who make decks weekly. Per-deck or per-week pricing suits the quarterly report, the single pitch, the one conference talk. If you are in the second group, a $4.99 deck is cheaper than any subscription, and a $108 annual seat to remove a badge is the most expensive option on the list for the least use.
When to stay with Gamma?
The test is fair to Gamma PowerPoint on one point: its own PowerPoint export is better than its reputation. Text and tables come through editable. If what you make is read on screen, the card-based format is a feature, and the credits and the badge do not bother you, there is no reason to move. Switch when you hit one of three walls: a chart you need to edit in PowerPoint, a client who objects to the badge, or a credit balance that runs out in the week you need it.
A two-minute decision
- Count how many decks you made last year and whether they left the browser.
- If fewer than ten and most were files, pay per deck.
- If weekly and shared on screen, pay for a seat, and pick the tool whose format your team already uses.
- Whatever you choose, open the exported PPTX before the meeting and check the charts. In every tool tested, that is where the pictures hide.
