Should I vibe code
Build structured presentations with reusable blocks, comments, and polished export
A deck is a performance, not a document. Yours has to run once, offline, on a screen you have never seen.

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
Slides in a browser are a solved problem — reveal.js has existed for a decade, and an agent will give you a themeable editor with reusable blocks in an afternoon. The gap is not the editor. It is that a deck is not a document, it is a performance: it has to run once, at a fixed time, on hardware you have never touched, at an aspect ratio you did not test, in a room whose wifi belongs to a hotel. Nearly everything Pitch charges for sits on that axis — presenter view on a second screen, fonts that travel with the file, offline playback, an export that looks the same as the thing on your laptop. The collaborative half is harder still, because the deck that matters is always being edited by three people ninety minutes before it is shown, and simultaneous editing on a canvas is the nastiest problem in this category. So build the renderer, keep the content in a text format you can hand to Keynote at six in the evening, and treat "export a PDF and open it locally" as the first feature rather than the last.
What actually breaks
not "if". the specific failures.
- Fonts, which are not installed on the machine you are presenting from, so the brand deck renders in Times New Roman in front of the client
- PDF and PPTX export, where a CSS grid becomes a flattened screenshot and every text box arrives uneditable
- The share link to the board deck, which was unlisted rather than private and is now sitting in an inbox at another company
- Presenter view, which needs a second screen, a synced clock and speaker notes that do not appear on the projector
- Three people editing the same slide ninety minutes before the meeting, one of whom overwrites the chart somebody spent the morning on
- Anything that needs the network at the moment you press play — remote images, web fonts, an embedded live chart
- Aspect ratio, when the room's projector is 4:3 and your deck has been 16:9 since the day you started it
- Embedded video, at the exact moment it matters, for reasons you will not have time to debug
Is that you?
the verdict is a default, not a law
- The deck's content lives in Markdown or a similar text format under version control, and the renderer is one of several possible views of it
- There is a working offline export and you rehearse from the export rather than from the app
- You are the only editor, or edits are serialised through you
- Nothing confidential is behind a share link whose only protection is that the URL is hard to guess
- The deck is a fundraise, a board meeting or a client pitch and there is no path that works without your server
- Several people edit at once and you have not built either locking or a real collaborative document model
- It has to produce a PPTX that somebody else will edit — that is a compatibility swamp, not a feature
- Confidential decks are shared by URL alone, with no expiry, no access log and no way to revoke
- Your fonts are licensed for the web and you are about to embed them in a file you hand to a client
If you build it anyway
the checklist, then the prompt that enforces it
- Build export first. Offline PDF and a self-contained HTML bundle that runs from a file:// URL with no network, before any editing polish exists.
- Bundle fonts as subsetted files inside the deck bundle and test on a machine that has never had them installed. Web fonts loaded at present-time are a single point of failure.
- Keep content in a text format that is diffable and lives in version control, so the renderer is replaceable and the deck is not.
- Design for one editor. If collaboration is required, add a visible lock with an explicit takeover before you consider real-time cursors.
- Make sharing explicit: expiring links, an access list for anything confidential, and a record of who opened it. Unlisted is not private.
- Support both aspect ratios from the start, and give a preview at the resolution of the room rather than the resolution of your laptop.
- Presenter view needs the notes, the clock and the next slide, and it must survive the display being disconnected and reconnected mid-talk.
- Rehearse the failure: unplug the network, open the export, present from that. If that path does not exist, the deck has a dependency you cannot control.
I am building a presentation tool: slides from reusable blocks, a theme and
sharing. Assume the deck is presented once, at a fixed time, on a machine and a
network I do not control. Order the work accordingly, and argue with me if I
want the editor before the escape hatch.
1. Export before editing. Produce an offline PDF and a self-contained HTML
bundle that runs from a local file with the network disabled. That bundle is
the deliverable; the app is a convenience.
2. Content is text: Markdown or similar, kept in version control, so the deck
outlives the renderer and diffs sensibly.
3. Subset and embed fonts into the export and the bundle. Never rely on a web
font fetched at present-time, and warn me when a theme references one.
4. Presenter view early — notes, timer, next-slide preview, on a second display,
surviving disconnect and reconnect. Most likely to be needed, least likely to
be tested.
5. Support 16:9 and 4:3, and let me preview at a resolution that is not my
laptop's.
6. Assume one editor. If I ask for collaboration, build a visible lock with
takeover first and tell me real-time canvas editing is the hardest thing here.
7. Autosave every change as a restorable revision. The failure that actually
happens is losing a slide at 10pm, not a breach.
8. Sharing is explicit: links expire, confidential decks need an access list,
revocation applies on the next request, views are logged. An unguessable URL
is not private.
9. Media is embedded and local by default. Remote images and live embeds are
opt-in, with a warning that they fail exactly when the room has no wifi.
10. Out of scope: PPTX round-tripping and viewer analytics. Finish by telling me
to rehearse from the offline export with the wifi switched off.That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.

the boring option, and the way back out
Whenever the deck's outcome matters more than the exercise of building it. Twelve dollars a month buys presenter view, offline playback, font handling and an export that matches the screen, which is the entire list of things that go wrong at the moment you cannot fix them. Building your own is a perfectly good project for internal decks and conference talks you control end to end — just not for the one where somebody decides whether to give you money.
$12/mo is cheaper than your weekend.
Because the content is text, the exit is mostly free: a folder of Markdown, images and a theme file opens in Slidev, reveal.js, Marp or a text editor on any afternoon. Keep an exported PDF of every deck you actually presented, dated and archived, because that PDF is the record of what an audience saw and it does not depend on your renderer still working. What will not survive is the editing experience — reusable blocks, the template library, comments — so do not put anything in those that is not also in the text.
Presentations authored in Markdown with components, presenter mode and PDF export — the version of this idea that keeps your content portable.

Questions
If reveal.js and Slidev exist, is there anything to build?
There is, and it is the editor rather than the renderer. What people want from Pitch is not slides in a browser, it is not having to write them in Markdown — the drag, the snap, the template that keeps a team's decks consistent. Building that on top of an existing renderer is a reasonable weekend and gets you most of the value; building the renderer as well is redoing solved work.
Why is data sensitivity scored at all for a slide tool?
Because of what goes in the decks. Board updates, runway, headcount plans and pricing all live in presentations, and presentations are shared by link more casually than any other document type. The tool is harmless; the contents are the most confidential thing most companies write down, and "unlisted URL" is the access control people assume they have.
What breaks on the day that I will not have predicted?
Fonts and the network, in that order. Your deck renders perfectly because the fonts are installed on your laptop and the images load from your server. Present from a borrowed machine on conference wifi and both assumptions fail at once, silently, with an audience watching. An offline bundle with embedded fonts removes both, and it is the reason this entry says build export first.
