Available from: Pro ($8.33/mo)
Why it matters: Several features advertised on the website are still marked 'Coming Soon' months after announcement
Available from: Pro ($8.33/mo)

👍 Fair value
Gamma produces significantly better-looking presentations with more sophisticated layouts, animations, and design elements. But Gamma is a standalone app — you create and share presentations inside Gamma's platform. SlidesAI's advantage is that it works inside Google Slides, so your output is a native Google Slides file you can edit and share like any other deck. Choose Gamma for design quality, SlidesAI for Google Slides workflow integration.
It's enough to test the tool: 12 presentations per year with 2,500-character input. That's roughly one presentation per month. If you only need occasional AI-generated slides, the free tier might be all you need. For regular use, you'll hit the limit quickly.
Yes. The output is standard Google Slides — you can edit text, move elements, change layouts, add images, and modify anything just like manually created slides. Most users generate a first draft and then manually polish it.
SlidesAI supports multiple languages for content generation, though English produces the best results. The quality of non-English output depends on the underlying AI model's training data for that language.
This is a legitimate concern raised by users. Features like advanced customization and certain template options have been listed as 'Coming Soon' for extended periods. Check the current feature list before purchasing a paid plan to ensure the features you need are actually available, not just planned.
Start with the free plan — upgrade when you need more.
