A free slide editor that runs in your browser with no install. Drag across an empty part of the slide to place a text box, then start typing right away. Drag a box to move it, and use the handles to resize it. Double-click to edit its text again.
Scroll the wheel to zoom smoothly around the pointer. Hold the space bar and drag, or drag outside the slide, to pan the view. Click the number in the bottom bar to fit the slide back to the window.
The Slides panel adds more slides and sets the background gradient from three colors and an angle, plus the accent color. The Text panel adjusts font size, line height, color, bold, italic, underline, and both horizontal and vertical alignment; the Transform panel sets the position and size of the box, and the Motion panel gives it an entrance animation. The File panel saves and loads your deck as JSON, and exports it as a PNG (the current slide) or a PDF (every slide).
Write math inline with $…$. Type something like $x^2 + y^2 = z^2$ and leave the editor, and just that part is typeset in proper math type; wrap it in $$…$$ for a formula on its own line. Blank lines separate paragraphs, and the text wraps around the formulas. Math is drawn into the slide itself, so it comes through in a PNG or PDF export and in presentation mode.
The four-corner icon in the bottom right starts a full-screen presentation, and the F key does the same. Click or press the arrow keys to advance, and press Esc to come back. Your work is saved in the browser as you go, so closing the tab and returning picks up exactly where you left off.
The Motion panel gives a text box an entrance animation. Pick one movement — slide in from beyond the edge of the slide, rotate, or zoom — and lay a fade on top of any of them. Duration and delay are in milliseconds, so staggering the delay from box to box makes them appear one after another. The animation only runs in presentation mode and during auto-play (the play button in the bottom bar); while you edit, every box stays where it comes to rest. A PNG or PDF export is drawn from that settled state as well.
Double-click a panel title to switch how the panels are laid out. In the movable layout you drag panels wherever you like and keep several open at once; in the fixed layout a single panel sits in the top right.
