SlidesAI - Pros & Cons
Pros
- ✓Cheapest AI presentation tool available — free tier actually works, and $100/year for Pro is less than most competitors
- ✓Lives inside Google Slides, so there's zero learning curve and no workflow disruption for Google Workspace users
- ✓Fast generation — paste text, click generate, get slides in under a minute
- ✓Privacy-focused: only requests minimal Google permissions, doesn't access other Drive files
- ✓Good enough for internal presentations, class lectures, and first drafts where design isn't critical
- ✓Document upload on paid plans saves copy-pasting from existing reports and briefs
Cons
- ✗Design quality is mediocre — themes are basic, layouts are repetitive, and the output looks AI-generated
- ✗Several features advertised on the website are still marked 'Coming Soon' months after announcement
- ✗Ignores custom color choices in some cases — you pick a theme and the AI uses whatever it wants
- ✗Content quality can be generic and surface-level, especially with shorter input text
- ✗Annual billing only for paid plans — no monthly option if you want to try before committing for a year
- ✗User review authenticity has been questioned — some reviewers appear to be using suspiciously similar language
Gamma - Pros & Cons
Pros
- ✓Very fast way to turn an outline into a polished presentation draft
- ✓Can create docs and webpages, not just slide decks
- ✓Good for async sharing through links instead of attachments
- ✓Low barrier for non-designers
Cons
- ✗Less precise design control than Canva, Figma, or traditional slide tools
- ✗AI-generated copy still needs review for important decks
- ✗Exports may be weaker than legacy presentation software
