Create, present, and share your slides

Use images or SVGs as backgrounds, place them beside text, or arrange them in a grid. Scale, crop, filter, and position them from Markdown.

Play videos stored with the presentation or clips from YouTube. Choose where they start, whether they play automatically or loop, and whether they begin muted.

Add audio and choose whether its controls appear on the slide. Start it automatically, loop it, or begin muted.

Add code in many languages, show line numbers, and highlight selected lines while you present.

Write formulas in TeX. Deckset formats them for the slide and keeps readable formula text in accessible exports.

Use Mermaid or Pikchr to create flowcharts, sequence diagrams, architecture diagrams, and more.

Try early support for turning data from CSV or JSON into a static chart with Observable Plot.

Add tables, columns, lists, quotes, links, footnotes, and inline text styles with Markdown.

Switch themes without rewriting the presentation. Each theme includes coordinated fonts, colors, and layouts.

Adjust fonts, colors, text styles, and backgrounds, then move theme files between Mac, iPhone, and iPad.

Change colors, alignment, spacing, scale, code colors, graph colors, and other theme settings on a single slide.

Choose 16:10, 16:9, 4:3, 1:1, or 4:5. If the screen changes, Deckset adjusts each slide for the new shape.

Use columns, place text beside media, arrange images in a grid, and let Deckset scale the content to fit.

Add persistent footers, logos, current slide numbers, and a total slide count. Override them when individual slides need less detail.

See your notes, the current slide, and what comes next while the audience sees only the presentation.

Set a target duration, then use color cues to see whether the presentation is on pace.

Show list items one at a time or highlight selected lines of code. Step backward through them when needed.

Choose fades, pushes, wipes, flips, zooms, and other transitions. Set their duration and direction for the whole presentation or one slide.

Present full-screen on Mac, iPhone, or iPad. On Mac, use a resizable presentation window for calls and hybrid meetings.

Switch the audience screen to black, or prepare a white screen with an image and text such as a QR code or Wi-Fi details.

Select which screen shows the presentation and switch the presenter view without restarting.

Advance the presentation from iPad with an Apple Pencil tap or squeeze.

Create a PDF/UA-2 file that keeps the reading order, headings, lists, tables, links, formula text, and media descriptions.

Keep the original slide dimensions, or create a smaller file that is easier to send.

Export one slide at full size, or place two or four slides on portrait A4 pages for compact handouts.

Include your presenter notes, every step in a build, or both when they help the reader.

Export every slide as an image at regular, double, or quadruple resolution.

Export an HTML presentation that works with a keyboard and keeps headings, lists, tables, links, media descriptions, and supporting files together.

Deckset points out accessibility issues before you save a PDF. On Mac, it also checks for missing descriptions, fonts, links, files, and content that may not work in a browser.

Write in any Markdown editor. Save the source file and Deckset updates the slides automatically.

Write and preview in the same app, including a side-by-side editing layout on iPad.

Keep Markdown, images, GIFs, video, audio, and presentation settings together when moving between devices.

Link to local images, audio, and video with Obsidian-style wikilinks. Deckset still handles the layout, playback, and accessibility options.

Review changes to the Markdown file in Git. The iOS app also keeps recent versions you can restore.

Install the Deckset skill in a compatible AI coding tool. Give it notes or an outline, and it can create or revise a Markdown presentation.

Use AppleScript to start or move through a presentation, or let another Mac app read the slide content and presenter notes.
