Nothing to install and no login. You can build slides and present them from this page.
Add slides with + in the list on the left, then click a title or body on the canvas to edit it in place. The toolbar above handles bold, italic and underline plus shapes, tables, charts and images. The panel on the right sets layout, background, transitions, theme fonts and accent colours. Press Present at the top right for full screen with speaker notes.
Choose a layout per slide and set the background to a solid colour, a gradient or an image. Add shapes, tables, charts and images, apply transitions, and mark slides to skip while presenting. Export the deck as a .pptx file, or import one you already have and keep editing.
Without an account your deck lives in this browser only. Clearing site data or opening it elsewhere loses it, and you cannot send it by link — though an exported file stays with you. Create a workspace and it is stored on the server so you can continue on another device and share it with your team.
