Skiaw vs Gamma

Gamma and Skiaw both turn a prompt into a finished deck, but they are built for different endings. Gamma's deck is a living card canvas you publish and share as a link; PowerPoint is one of several export targets. Skiaw's deck is a PowerPoint file, the whole engine exists to make that file exact. This page sets the two side by side, with every Gamma claim traced to Gamma's own pages.

Which one should you pick?

The short answer, before the evidence. The table below is there so you can check it.

Choose Skiaw if…

  • The deliverable is a .pptx someone else will open, edit and re-present in PowerPoint.
  • Your slides need figures that cite a source you can point at in the room.
  • Brand colours and typography have to be exact, not approximately right.
  • You would rather pay one flat price than watch a credit balance while you edit.

Choose Gamma if…

  • You want one tool for decks, docs, websites and social posts rather than decks alone.
  • You need to publish to a custom domain or track who viewed what.
  • You want to try a capable free tier before paying anything.
  • Your organisation requires a SOC 2 Type II attestation from every vendor.

Feature comparison between Skiaw and Gamma, grouped by category. Each row gives the feature, why it matters, and how each product handles it.
PowerPoint output
Native .pptx exportDecides whether the person you send the file to can actually edit it.
Yes:

Skiaw

Native .pptx, every element is a real PowerPoint shapeSee source [1]

Text stays selectable and editable. No slide is exported as a flat image.

Yes:

Gamma

Exports to PDF, PPTX, PNG and Google Slides on every planSee source [4]

Font embeddingWithout embedded fonts your deck reflows on a machine that lacks them.
Yes:

Skiaw

Fonts embedded in the file itselfSee source [1]

A separate web-safe copy is produced too, because PowerPoint on the web refuses files with embedded fonts.

Partly:

Gamma

Embeds the theme's heading and body fontsSee source [6]

Gamma states that "italic text uses a slanted version of the regular font rather than a true italic font file, which can look slightly different from what you see in the editor."

Layout fidelity in the exported fileThe gap between the preview and the file is the work you do by hand afterwards.
Yes:

Skiaw

Geometry measured from the rendered page, exact to 1 EMUSee source [1]

Our own check across 914 shapes in reference and production decks: every box landed on the unit.

Partly:

Gamma

Most styling survives; some effects fall backSee source [6]

Gamma notes that gradient headings, frosted backgrounds and some advanced visual effects may render differently or use fallback styles in PowerPoint.

Exports without vendor brandingA logo that is not yours on a client deck is a problem.
Yes:

Skiaw

No Skiaw branding on exportsSee source [2]

Including the $1 trial.

Partly:

The deck is already an exact 1280×720 layout, so printing gives one slide per page. There is no separate PDF engine.

Yes:

Gamma

PDF export on every plan, including FreeSee source [4]

Charts in the exported fileDetermines whether a reviewer can correct a number without redrawing the chart.
Partly:

Skiaw

Charts drawn as native vector shapesSee source [1]

Yes:

Skiaw

Length follows the briefSee source [2]

Credits are the limit, not a per-prompt slide cap.

Partly:

Gamma

10 on Free, up to 75 on Plus and aboveSee source [4]

Cost of revising a deckIf edits are metered, you stop editing before the deck is finished.
Yes:

Skiaw

Conversational edits, and they cost no creditsSee source [2]

Revising a deck is free by design, you should not ration fixes.

Partly:

Gamma

AI edits draw on the same credit balance as generationSee source [5]

Gamma states that all AI features use credits, "including Agent and adding slides with AI", though errors and clarification requests are not charged.

Design and brand
ThemesA generic template is why every AI deck looks like every other AI deck.
Yes:

Skiaw

Six hand-built themesSee source [3]

Where the two actually diverge

Four differences that a table row is too small to explain properly.

01

What “exports to PowerPoint” actually means

Almost every AI deck tool exports a .pptx. The files differ enormously. At one end the slide is a picture in a PowerPoint wrapper, it opens, it looks right, and nothing on it can be changed. At the other end every heading, bullet, rule and shape is a real object your colleague can select and retype.

Skiaw only produces the second kind, and the pipeline is built backwards from that requirement. The deck is laid out in a browser, then the geometry, not the pixels, is read out of the rendered page and turned directly into PowerPoint shapes. Because a PowerPoint slide is exactly 9,525 EMU per pixel on both axes at our canvas size, that translation is arithmetic rather than approximation.

Gamma also exports .pptx on every plan, and embeds your theme's heading and body fonts into the file. Its own documentation is candid about the edges: italics are synthesised by slanting the regular weight rather than using a true italic face, and gradient headings, frosted backgrounds and some advanced effects may fall back to simpler styling in the exported file. If your deck lives inside Gamma and PowerPoint is an occasional handoff, that is a reasonable trade. If PowerPoint is the destination, the gap is work you do by hand.

02

Decks that are checked before you ever see them

The failure mode of generated slides is not an obvious crash. It is a caption that slid a few millimetres off a chart, a line of text pushed past the slide edge, a box that quietly overlaps another. You find these in the room.

Skiaw runs two automated gates on every deck. The first proves that everything painted on the slide is something the deck claims to have drawn, anything left over is an omission, and it fails. The second proves that everything claimed lands where it was measured to land, to within a single English Metric Unit. Across 914 shapes in our reference and production decks, the geometry matched exactly.

A slide that fails a gate is regenerated rather than patched. Repairing a broken layout tends to produce a second, subtler break; rebuilding it does not. We could not find equivalent published checks for Gamma, so this row is marked as undocumented rather than absent, it may exist and simply not be described.

03

Slides that can name where the number came from

A generated deck that invents a market size is worse than an empty one, because it reads as finished. Skiaw searches the web and reads the files you attach, PDF, DOCX, PPTX, TXT, Markdown, before any slide is written, and builds a brief in which every figure carries a tag that resolves back to its source. Those tags surface on the slide itself, so when someone asks where the 34% came from, the answer is on screen.

Gamma documents importing your own PDFs and PPTX files as a starting point. On the pages we checked it does not describe searching the web during generation or attaching citations to figures, so we have marked both rows undocumented rather than unsupported.

04

How the two price models feel in practice

Both tools meter AI usage with credits, and the difference shows up in editing rather than generation. Gamma states that all AI features draw on the credit balance, including adding slides and using its agent, though errors and clarification requests are not charged; unused credits roll over up to twice your plan size, and the free tier's 400 credits are a one-time grant that never refreshes.

Skiaw meters generation the same way, 700 credits a month on Pro, ten for a fast deck and twenty for the best one, so roughly 35 to 70 decks. Conversational edits cost nothing. That is a deliberate choice: the tenth revision is usually the one that makes the deck good, and a meter running during it changes how you work.

One honest caveat on the numbers below: Gamma prices its plans by region, and the figures we could verify were the European ones, in euros. Check gamma.app/pricing for your own currency before comparing to the dollar.

Where Gamma is the better choice

We built Skiaw and we would still send you elsewhere for these. If one of them is your requirement, Gamma is the better buy today.

  • Gamma is a broader product. It makes documents, websites and social content as well as decks, and Skiaw does none of that.
  • It has a genuinely usable free tier, 400 credits, no credit card, so you can judge the output before spending anything.
  • Publishing is a first-class feature: hosted pages, custom domains, viewer analytics and advanced sharing. Skiaw has none of these.
  • It offers a public API on the Pro plan for generating decks from your own systems. Skiaw has no API.
  • Gamma states it is SOC 2 Type II compliant. Skiaw has no such attestation, which will rule it out at some companies today.
  • You can buy Gamma right now. Skiaw's subscriptions are still opening, so the honest comparison includes waiting.

Frequently asked questions

The questions people ask before switching between Gamma and Skiaw.

Is Skiaw a drop-in replacement for Gamma?

No. Gamma covers presentations, documents, websites and social posts, and it hosts and tracks what you publish. Skiaw does one thing: it generates presentation decks and exports them as PowerPoint files. If you rely on Gamma's publishing, custom domains or viewer analytics, Skiaw does not replace them.

Do both tools export editable PowerPoint files?

Both export .pptx. Gamma exports to PDF, PPTX, PNG and Google Slides on every plan and embeds your theme's heading and body fonts, while noting that italics are synthesised from the regular weight and that some effects such as gradient headings and frosted backgrounds may fall back in the exported file. Skiaw's engine exists specifically to produce the PowerPoint file: every element is a real shape and the geometry is measured from the rendered page rather than approximated.

Which one is cheaper?

Gamma's paid tiers start at €10 per seat per month, or €8 per month billed annually, for 1,000 credits. Skiaw's Pro plan is $20 per month, or $16 billed yearly, for 700 credits, roughly 35 to 70 decks. Gamma prices by region, so check gamma.app/pricing in your own currency. Gamma also has a free tier; Skiaw has a $1 seven-day trial instead.

Does Gamma remove its branding from exports?

Only on paid plans. Gamma's help documentation states that only Plus and Pro users can export without the Gamma watermark. Skiaw exports without Skiaw branding on every plan, including the $1 trial.

Does Skiaw cite its sources?

Yes. Skiaw searches the web and reads the documents you attach before writing, and every figure in the brief carries a tag that resolves to its source and is shown on the slide. Gamma documents importing PDFs and PPTX files, but does not describe web research or figure-level citations on the pages we checked.

Can I sign up for Skiaw today?

Subscriptions are still opening. You can reserve a plan and we will email you when checkout goes live. Gamma is available for self-serve purchase now.
