Settle the ask before you open any tool
Most of the work happens before the first slide. Write down who will be in the room, how long you have, and the one decision or takeaway you want at the end. Then gather the facts only you know: dates, amounts, names, results so far. A generator can arrange those facts; it can't supply them.
The example here follows Dana Ruiz, a fictional branch manager with ten minutes at a library board meeting to request $1,000 for a monthly repair café pilot. Dana's notes already hold four budget lines, four Saturday dates and six volunteer sign-ups. What's missing is a deck that opens with the request instead of saving it for the last slide.
Pick the route that produces the file you need
You have three reasonable options. A template in the slide software you already use gives you full control, but you do the layout yourself. A dedicated AI presentation maker can start from a prompt or an uploaded document, let you edit the outline, and then build a styled draft. Some let you adjust the audience, length and level of detail, and you can download the result as a PDF or PowerPoint file.
The third option is asking a general AI assistant to write the deck as a single HTML file. HTML is the markup behind a web page, so the file opens in a browser without presentation software, and you can ask for a layout that reads on a phone. It isn't a PowerPoint file, though.
Let the submission rule decide. If the board secretary wants a PDF in the meeting packet, choose a route that produces one and send it. A web page can travel alongside that file, not in place of it.
What the sample deck shows
The sample below is Dana's deck built as one page, with each block doing the job of a slide. The branch, dates, costs and volunteer count are all invented for illustration.
Two choices are worth borrowing. The request and the dollar figure come first, so a board member skimming on a phone before the meeting sees the decision before the background. The last block lists exactly what the board is voting on, which gives the discussion somewhere to land.
The budget is a plain table with a total row instead of a chart. With four line items, the numbers themselves are the clearest picture, and a two-column table holds up on a narrow screen.

Make your own with the prompt
Replace every bracketed placeholder with your own details, then paste the prompt into whichever AI assistant you use. If you don't have a number yet, leave [TBD] in place; the prompt tells the model to keep that marker rather than invent a value.
When the file comes back, open it in a browser and check three things before anyone else sees it: every figure matches your notes, the text stands out clearly from its background, and the page fits a phone screen without sideways scrolling. If a slide feels crowded, cut words before you shrink the type. The same checks apply to a draft from a dedicated slide tool.
Build a short presentation as one self-contained HTML file.
Context
- Presenter: [your name and role]
- Audience: [who will see it, e.g. library board, 7 members]
- Setting and length: [where you present, how many minutes]
- The one decision or takeaway I need: [e.g. approve $1,000 for a four-month pilot]
Facts to use
- [fact 1: a date, amount or name]
- [fact 2]
- [fact 3]
- Budget lines, if any: [item: amount], [item: amount]
Use only these facts. Do not add statistics, quotes, testimonials, logos or results I did not provide. If something you need is missing, write [TBD] instead of guessing.
Structure
- 5 to 7 slides, each a <section> with one h2 heading; slides stack vertically and the page scrolls (no slideshow JavaScript)
- Slide 1 states the request and the key number in one or two sentences
- Show any budget as a real HTML table with header cells and a total row typed as text
- The final slide lists exactly what the audience is deciding or doing next
- Keep each slide to roughly 40 words of body text
Output requirements
- One HTML file, CSS inside a <style> tag; no external scripts, fonts, images, trackers or links to outside services
- No forms, no buttons that submit or send data, no download or export features
- Mobile: single column below 600px wide, no horizontal scrolling, body text at least 16px
- Accessibility: one h1 for the deck title, then h2 per slide; strong contrast between text and background; never use color alone to signal meaning; lang attribute set on the html element
- Return only the code, with no explanation before or after it
When the plan changes after you've shared it
Suppose the board approves the pilot but pushes the start to February. That date sits in the opening request and again in the schedule. Asking AI to regenerate the whole deck for one date can reword slides you already approved, and emailing a corrected file leaves people holding two versions.
This is where NOS earns a place. Keep the HTML page in your NOS workspace and edit the rendered text directly, with no new AI request. If you've published a sharing link, the link stays the same after your edit, so board members who open the one they already have see February. They don't need an account to open it.
Two cautions. Only text edits are covered here, and the budget total is typed text rather than a formula, so if a line item changes, update the total row yourself. And if the packet requires a PDF, send the corrected PDF too; the link is simply the copy people can come back to between meetings.
