Generative AI has changed how presentations get made, and SlidesAI is one of the most widely installed tools in that category, with more than 14 million downloads and a native add-on for both Google Slides and PowerPoint. This guide covers what SlidesAI is, its core features, pros and cons, how to use SlidesAI and download your slides, whether SlidesAI is safe and legal to use, and how it stacks up against five real alternatives — including Smallppt.
What Is SlidesAI?
SlidesAI is a generative AI presentation add-on that installs directly inside Google Slides and Microsoft PowerPoint. Instead of building an app you leave your slide editor for, SlidesAI works as a panel inside the software you already use: you type a topic or paste your notes, and the AI organizes them into sections, writes slide content, and applies a template — all inside the native editor. It's used by teachers, students, and business professionals, and its client list includes companies like Amazon, HubSpot, Microsoft, and Nvidia, along with universities such as MIT, Stanford, and Cambridge.
Key Features
- Text-to-Slide AI Generation
Paste a topic or long-form notes and the AI drafts a full outline and slide deck in seconds.
- Native Google Slides & PowerPoint Integration
Runs as an add-on inside both platforms, so there's no new software to learn.
- Tone and Content Refinement
Rewrite, shorten, or adjust the tone of any slide directly from the panel.
- 150+ Templates
Pick from a library of customizable professional layouts and themes.
- AI-Generated and Stock Imagery
Add AI visuals or royalty-free stock photos without leaving the editor.
- 100+ Supported Languages
Generate and translate slide content across major world languages.
- ChatGPT Integration
A custom SlidesAI GPT can turn a ChatGPT conversation into a saved Google Slides deck.
- PPTX Export
Export presentations as PPTX files fully compatible with both Google Slides and PowerPoint.

How to Use SlidesAI
Creating a presentation with SlidesAI takes three steps
STEP 1
Install and launch
Add SlidesAI from the Google Workspace Marketplace or the PowerPoint add-in store, then open a new or existing presentation.
STEP 2
Generate and customize with AI
Type a topic or paste your notes, choose a tone, and select a template. Preview the outline, then generate the slides.
STEP 3
Refine, share, and download
Edit wording, rephrase, translate, or adjust layout directly from the panel, then export the finished deck.
Is SlidesAI Safe and Legal?
SlidesAI is a legitimate, paid SaaS product operated by Zesterv LLC, listed on the official Google Workspace Marketplace and Microsoft AppSource, which both run their own app review processes before an add-on is publicly listed. Billing is processed through Paddle.com, which acts as SlidesAI's merchant of record.
Things to check before you rely on it for sensitive work
SlidesAI uses royalty-free stock imagery by default, but licensing terms can vary by image source, so it's worth double-checking usage rights for commercial decks. If you upload confidential notes or documents, review SlidesAI's privacy policy for how your input data is stored and used. As with any AI writing tool, always fact-check AI-generated content before presenting it, since AI can occasionally produce inaccurate statements.
