How to Write Presentation Content

Writers overload slides for a reasonable-sounding reason: it feels efficient to say everything related to a topic in one place. But an audience does not experience a slide as a container of related facts — they experience it as a single unit of attention, on screen for maybe thirty seconds. If that unit contains two ideas, most people retain neither cleanly. They either merge the ideas incorrectly or forget one entirely.

The test is simple: read your slide content back and ask what it wants the audience to walk away believing. If you can answer with one sentence, you have one idea. If your answer needs "and" — this happened, and also this other thing is true — you have two slides pretending to be one. Split them. The content on each half almost always gets sharper once it is not sharing space with something else.

This discipline compounds. A ten-slide deck where every slide carries one clean idea reads faster and lands harder than a six-slide deck where each one is crowded. Length is not the enemy of clarity; crowding is. Once you accept one-idea-per-slide as a rule rather than a suggestion, most of the other writing decisions below get easier, because you are never trying to cram two arguments into one box.

This is the difference between a table of contents and an argument. Labels ("Market Overview," "Our Approach," "Next Steps") tell the audience what category of information is coming but commit to nothing. Claims tell them what to think. If someone skimmed only your headlines — top to bottom, ignoring every bullet and chart — they should walk away with the shape of your argument. That is a genuinely useful test to run on a finished draft: strip everything but the headlines and read them as a paragraph. If it does not make sense as an argument, the headlines are still labels.

Writing headline-first also changes the order you draft in. Instead of dumping bullets onto a slide and titling it afterward, decide the one thing the slide needs to prove, write that as the headline, and then write only the content that supports it. Anything you find yourself adding that does not support the headline belongs on a different slide or nowhere.

Keep headline claims short — most land in six to twelve words. A claim that needs two clauses to state usually means the slide is still carrying two ideas. If you cannot compress the point to one clean sentence, that is useful information: go back to the one-idea test above before you polish the wording.

"Our onboarding is fast and intuitive" tells the audience nothing they can verify or remember. "New users complete setup in under four minutes, down from twenty-two" tells them something specific, checkable, and far more persuasive — and it happens to be more memorable too, because concrete numbers stick in a way that adjectives never do. Every time you catch a superlative or a vague quality word in your draft, ask: what is the fact that made me want to use that word? Write the fact instead.

This applies to comparisons and reassurance language just as much as to claims of quality. "Significantly faster" becomes "40% faster on the same dataset." "Trusted by leading teams" becomes naming three teams, or a number, or nothing at all if you cannot substantiate it. If you genuinely have no evidence for a claim, that is worth noticing — it might mean the claim is not ready to be on a slide yet.

One caution: evidence should match the size of the claim. A single anecdote does not support a universal claim ("everyone loves it"), but it can support a specific one ("one customer cut onboarding time in half"). Scope your evidence honestly and your audience will trust the rest of the deck more, including the parts they cannot independently check.

Documents get read at the reader's own pace, with the option to pause, reread, and look things up. Slides get read once, briefly, while a speaker is also talking. That is a completely different medium, and it demands different sentences. Long subordinate clauses, dense jargon, and stacked qualifiers all work fine on a printed page and all fail on a slide, because there is no time to untangle them before the speaker has moved on.

A practical habit: draft your slide content, then read it aloud exactly as written. Anywhere you stumble, backtrack, or want to rephrase on the fly, that is a sentence that will not survive being heard once. Break it into two shorter sentences, or cut the qualifier, or replace the jargon with the plain word a colleague outside your field would use.

Contractions, short words, and active voice all help here — not as style preferences but because they are easier to parse at listening speed. "We have decided that a phased rollout is the approach we will take" becomes "we are rolling this out in phases." Same information, half the parsing effort, and the audience is still with you by the next slide instead of catching up.

1. Draft without editing. Get the argument and the evidence onto the page in full sentences first. Trying to write tight and correct at the same time slows down the thinking, and thinking is the hard part.

2. Cut hedges and filler. Phrases like "we believe," "it is worth noting that," and "in many ways" add length without adding information. Delete them and reread the sentence — it almost always means the same thing, faster.

3. Cut restatement. If a bullet just rephrases the headline in different words, it is not supporting the claim, it is padding the slide. Either replace it with actual evidence or remove it.

4. Cut until removing one more word would lose meaning. That is the actual finish line for a slide, not a word count or a template. Some slides land at eight words, some need forty to make a real point — the length should be decided by the idea, not by a rule of thumb about bullet counts.

It is tempting to open a slide tool and start placing text boxes, because progress feels visible immediately. But writing inside a canvas pulls your attention toward font size and box placement before the sentence is even finished, and weak writing hides behind a good-looking layout far too easily. Separating the two jobs — write, then design — means every editing decision above (splitting a crowded slide, tightening a headline, cutting a hedge) happens while it is still just text, which is the cheapest possible place to fix it.

This is the whole idea behind working content-first, which is how Eazy is built: you write your presentation as a real document first — headings for slide topics, bullets for the supporting points, dividers where one slide ends and the next begins, notes alongside your content for anything you want to remember but not show. Nothing about layout gets decided yet. You can draft that document from a prompt, or bring in a source you already have — a PDF, Word file, PowerPoint, spreadsheet, or a web link — and Eazy reads it into that same editable content, so you are shaping real sentences rather than staring at a blank page.

Once the writing holds up on its own — you can read the headlines as an argument, every slide has one idea, the evidence replaces the adjectives — you design. In Eazy every slide is designed for you and on-brand by default, and you can restyle the whole deck at once by applying a theme rather than reformatting slide by slide. If a line changes later, you edit that one line and only that slide rebuilds, because the document stays the source of truth the whole time, not a draft you abandon once the slides exist.

The practical takeaway is small but changes everything downstream: open a real editor before you open a design surface. Write the argument, cut it hard, read it aloud, and only then think about how it looks.
