A focused picture-description editor

What it helps with

The editor shows slide order, slide titles, embedded-image previews, and existing descriptions. It supports undo and downloads a new presentation copy. It does not write descriptions automatically or make accessibility decisions for you.

It is a beta for ordinary unencrypted .pptx files, with editing on slides 1–20 free. A $4.99 one-time full version is planned, but purchases and unlocking are unavailable. See supported files and exclusions.

How the examples were made

The seedling photograph is an original AI-generated illustration. The germination chart and its numbers were created for this exercise: 12 of 20 seeds in Tray A and 18 of 20 in Tray B after seven days. They are invented data, not research results.

The six-slide practice deck was built for this guide. It deliberately includes repeated images with different purposes, a grouped picture, a decorative picture, and a native chart outside the editor’s scope. It contains no user teaching or research deck content.

Evidence and limits

The editor has been tested with synthetic presentations in Chrome and Edge on macOS, including selected changes, undo, and package-content preservation. Those tests cannot establish compatibility with every presentation or every assistive technology. Review each exported deck in PowerPoint before sharing it.

The tool does not certify accessibility compliance. Useful descriptions are one part of a wider presentation review.

Operator and contact

Alt Text for PowerPoint is operated by Professor A2Z. Support and privacy contact: professora2z2026@gmail.com.

Useful bug reports will include your browser, the steps you took, and the exact error message. Avoid sending confidential presentations; a small synthetic file that reproduces the issue is preferable.

How the guide is funded

The editor is free for slides 1–20 and has no ads. The plan is to show Google AdSense ads on the guide pages only, never in the editor. See the privacy notice.

Factual claims in the guides link to the primary source we checked, such as ADA.gov, the Federal Register, W3C or Microsoft Support, and quotations are copied exactly.

Independence

This project is not affiliated with or endorsed by Microsoft. PowerPoint is a Microsoft product. The guide links to external accessibility resources for further reading; those organizations do not endorse this tool.
