Our verdict, the regret score and everything below it. Editorial and unsponsored — nobody can pay to be moved.
The honest answer
why the verdict is what it is
A canvas with draggable text and image layers is a satisfying Saturday, and it will look like the real thing by Saturday night. The gap between that and Visme is not the canvas — it is export fidelity, and export fidelity is where design tools go to die. Visme's paid tiers exist to hand you a PPTX that opens in PowerPoint with the fonts intact, an HTML5 embed that behaves in an iframe on somebody else's CMS, an MP4 of an animated slide, and a PDF whose text is selectable and whose vectors did not get flattened into a screenshot. Each of those is a specification you cannot half-implement. Your version will produce a PNG that looks correct in Chrome on your laptop, and the first time a colleague opens the deck on Windows with a font you never embedded, the layout will be wrong in a way that is visible from the back of the room. Nothing here is dangerous — the worst outcome is an embarrassing slide and an afternoon lost — which is exactly why it is DEMO ONLY rather than anything sharper. Build it to learn how compositing works. Do not build it because you have a board meeting on Thursday.
What actually breaks
not "if". the specific failures.
- Fonts, always and first. Text laid out with a webfont and exported without embedding it reflows on any machine that does not have it, and the reflow is never small
- PPTX export, which is not a file format so much as a zipped XML dialect with a long memory, and which PowerPoint will silently repair, reflow or refuse
- PDF text, which turns into an image the moment your renderer takes the easy path, so nobody can copy a quote out of your deck and search engines cannot read it
- The document format you invented in week one, which acquires a version field in week six and an unmigrated backlog of old files by month three
- Undo, which every editor demo skips and every real user reaches for within ninety seconds
- Share links, which are permanent by default, so the pitch deck sent to one investor stays open to anybody who has ever had the URL
- Video and GIF export, which means a rendering pipeline, a frame scheduler and ffmpeg, and which is a project rather than a feature
- Browser drift, because a canvas app is a bet on rendering behaviour that changes under you every six weeks
Is that you?
the verdict is a default, not a law
- The output is a PNG or a web page you control, and never a file somebody else opens in another application
- Documents are saved as plain JSON in a folder or a repository, and you can open last year's
- It is your own decks and a wrong margin costs you nothing
- You are doing it to understand layout and compositing, and you know that is what you are doing
- Anyone downstream expects a working .pptx or a print-ready PDF
- The only copy of a document lives in your app's database in your app's format
- Share links have no expiry and no visible indication that a document is public
- There is a deadline attached to the deck
If you build it anyway
the checklist, then the prompt that enforces it
- Pick the export format before you design the document model. A model built for canvas rendering and retrofitted to PPTX is a rewrite; the constraints run the other way.
- Use a real library for anything leaving the browser — pptxgenjs, a proper PDF engine, ffmpeg for video. Nobody should be hand-writing OOXML in a side project.
- Embed or subset every font you render with, and test on a machine that has none of them installed. This is the single most common way a homemade deck betrays itself.
- Store documents as versioned JSON with a schema version in every file, and write the migration when you change the schema rather than after.
- Export to disk on a schedule, into a directory the app cannot delete. A design tool whose only copy of your work is its own database is a data-loss story waiting for a bad deploy.
- Build undo and redo early. It is a command stack, it is architectural, and bolting it on later means touching every mutation you have written.
- Give share links unguessable identifiers and a default expiry, and mark any publicly readable document visibly in the editor.
- Cap image sizes and store uploads as blobs outside the document, or the first deck with twenty screenshots becomes a multi-megabyte row that is slow to load forever.
I am building a presentation and infographic editor. The interesting part is
the canvas and the part that decides whether it is useful is export, so invert
my instincts and work in this order.
1. Ask me first what the output has to be — PNG, PDF, PPTX, MP4, an embed. If
the answer includes PPTX or print-ready PDF, tell me plainly that those are
the hard part and will constrain the document model.
2. Design the document model against that answer before drawing a single
rectangle. Versioned JSON, schema version in every file.
3. Build export second, on a hardcoded sample document, before there is any
editor at all. If export cannot be made to work, I want to know on day one.
4. Use libraries for export. pptxgenjs for PowerPoint, a real PDF engine for
PDF, ffmpeg for video. Refuse to hand-generate OOXML.
5. Embed or subset every font used in an exported file, and show me the export
rendered on a machine that does not have those fonts installed.
6. Keep PDF text as text. If the renderer is about to rasterise a whole page,
stop and tell me, because a flattened PDF is a screenshot with a file
extension.
7. Then persistence: documents saved as files, plus a scheduled export of
every document to a directory the app cannot touch.
8. Write the schema migration path before the second schema change, not after.
9. Only now the editor. Build undo and redo as a command stack from the first
mutation — retrofitting it means rewriting every edit operation.
10. Uploaded images are blobs stored outside the document, with a size cap and
a generated preview.
11. Sharing gets unguessable IDs, a default expiry, and a visible marker in
the editor when a document is publicly readable.
12. Out of scope unless I insist: real-time collaboration, comment threads,
an asset library and animation timelines. Say so rather than starting
them. Visme is $29 a month per person with all four already working.That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.
their build prompt ↗Or don’t build it
the boring option, and the way back out
As soon as a file has to open on somebody else's computer. $29 a month per person for Starter, $59 for Pro, and Pro is the tier that carries PPTX, HTML5, video and GIF export plus the brand kit — which is to say you are paying precisely for the part that is hard to build and invisible when it works. The free tier is generous enough to answer the question for you: make the deck in it, and if the export is fine, you never needed the project.
$29/mo is cheaper than your weekend.
Everything hinges on the file format. If documents are versioned JSON on disk plus their exported artefacts, abandoning the project costs nothing — the PNGs, PDFs and PPTX files are the actual deliverables and they outlive the editor by definition. If documents only exist as rows in your database, in a shape only your renderer understands, then shutting the app down destroys the work. Decide which of those you are building on the first day, because after fifty documents the answer is fixed.

Questions
Why is export so much harder than the editor?
Because the editor only has to satisfy one renderer, the one you are testing in, and export has to satisfy every renderer you have never seen. A browser canvas is forgiving: it lays out with the fonts on your machine, at your device pixel ratio, in your version of Chrome. A .pptx is opened by PowerPoint on Windows, Keynote on macOS and Google Slides in a tab, each with its own opinion about spacing, shadows and missing typefaces. You are not exporting a picture, you are making a promise about somebody else's software.
What is the smallest version actually worth building?
A deck-as-code tool. Write the content in Markdown or JSON, render it with a template you control, output HTML and a PDF. You lose the drag-and-drop and you keep everything that made you want the tool — consistency, versioning in git, and files that still open in three years. Several of the best presentation tools in existence work exactly this way, which is a hint.
Where does the interactive stuff fit?
It is the part that ages worst. Visme's interactive assets — hover states, embedded charts, clickable hotspots — are a bet on a runtime, and a runtime you wrote yourself has to keep working in browsers that ship every six weeks forever. A static export has no such obligation. If you build the interactive version, at minimum keep a flat PDF alongside every document so the content survives the runtime.
Every week, someone ships something they shouldn’t have.

The canvas is a weekend. The font licence you embedded in that merch export is a letter from someone's lawyer.
A deck is a performance, not a document. Yours has to run once, offline, on a screen you have never seen.
