AI Slide Editor by CubeOne - The editor PowerPoint should've shipped

by•
CubeOne is an AI slide editor you talk to. Describe a slide and it designs one, or drop in rough notes and images and it makes a polished slide. Point to any spot, say what you want, and it adds it: a chart, an image, a table. Ask it to edit or restyle, and it does. Everything stays editable.

For launch we're giving away free credits for new signups, open until they run out. Try it here: . Let us know what you think.

 Free to try with no credit card is a great way to lower the barrier here. One question: when it restyles a slide on request, does it keep brand colors/fonts consistent across the rest of the deck, or do you have to manually sync each slide?

Maker
You have a brand system that keeps all slides consistent. And you can customize the brand too.

Eric, congrats on the launch! In enterprise presales, the biggest bottleneck is almost always translating a messy page of technical discovery notes into a clean, digestible client deck. The fact that CubeOne lets you just drop in those rough notes and point to specific spots to generate charts or tables is a massive workflow shift.

Quick question: How well does the AI handle complex data structures? If I paste in raw technical specs or unstructured CSV data, can it reliably format that into a clean comparison table on the slide?

Maker

 Yes. The trick is matching the model to the complexity. For complex or messy inputs like raw specs or unstructured CSVs, use a stronger model like Opus, or at least Sonnet, for the cleanest results. For simple or straightforward work, Gemini 3.1 Flash Lite handles it fast and well.

The 'go from nothing to stage-ready in 5 minutes' promise speaks to anyone who dreads pitch deck design. For builders, slides are usually a bottleneck. Love that this provides a script alongside the visuals to keep the presentation structured. Does the platform allow for custom brand assets or design styles to make sure the output doesn't look identical across different users? Huge congrats on the launch!

Maker

 absolutely. 1) think design.md. prompt your brand assets in plain English 2) or bring your own pptx template (#2 is still beta. covers ~80% of cases, not reliable for complex pptx). on top of that, you can turn any CubeOne project you like into a template, so new projects come out in that style.

The freeform editing + Beautify combo is genuinely clever - most AI slide tools give you output you can tweak but not actually own. The fact that everything stays a native editable object is what makes this actually usable.

Curious though, how does Beautify handle brand consistency across a whole deck? Like if I have 12 slides and I Beautify slide 4, does it know what slides 1–3 look like and match the style? Or does each slide get redesigned independently and you end up with a deck that feels slightly different across sections?

Maker

 You have a brand system with two ways to set it up. 1) treat it like a design.md. prompt your brand in plain English. 2) bring your own template. This is still beta. It covers 80% of cases but isn't reliable for very complex PPTX. You can also turn any CubeOne project you made into a template, so new projects come out in that style.

 The design.md approach is smart, treating brand as a prompt rather than a locked template gives you way more flexibility. The 80% caveat is honest, most tools would've hidden that. Rooting for the complex PPTX edge case to get cracked in v2.

The no lock-in angle is what really matters here. Gamma and generate slides that look great in a demo, but they fall apart the moment a client asks you to tweak a font or move a logo. In CubeOne, every element stays a real, draggable, editable object – not a flattened image. That's the detail most AI slide tools quietly skip over.
One open question is the PowerPoint round-trip: if I import a complex existing deck with custom layouts and embedded charts, how faithfully does it export back to .pptx after editing?

Maker

 Really depends on the complexity of that PPTX. Very complex files can still hit layout mismatch. This is a feature we iterate on over time. It now handles 80% of cases and gets more reliable day by day.

shipped SVG support 10 mins ago and it's already way better than my demo. one-shot this:

When CubeOne turns rough notes into a deck, how much of the story and speaker script can users control versus letting the AI decide the narrative?

"The editor PowerPoint should've shipped" is a bold framing and I'm here for it — the native editor really hasn't moved in years. Curious where you landed on export: do files round-trip back to real .pptx cleanly, or is editing locked to your environment? That fidelity is usually where "better PowerPoint" tools live or die for corporate users who still have to hand a .pptx to their boss.
