Pros and cons
From each tool's full review, written from the same checked facts.
Gamma
Pros
- Turns a written prompt, an outline or an uploaded Word document, PDF or Google Doc into a structured deck automatically.
- Imports existing PDF and PPTX files and exports finished decks to PDF, PPTX, PNG or Google Slides.
- Supports real-time multi-person editing plus a view-and-comment-only mode for reviewers.
- Names Claude, ChatGPT and DALL-E, Gemini, Flux, Recraft, Playground, Ideogram, Luma and Leonardo as the AI models behind its content and image generation.
- Publishes a deck as a live web page with view and slide analytics from the Pro plan up.
- Holds a SOC 2 Type II report and includes single sign-on on the Business plan.
- Gives 400 credits at signup on a free plan that needs no credit card.
Cons
- Free plan output carries Gamma's own branding, which is only removed starting on the Plus plan.
- Does not edit an existing AI-generated image, only regenerate a new one from a follow-up prompt.
- API access is limited to the Pro and Ultra plans and draws on the same AI credit allowance.
- Publishes no time-limited free trial of its paid plans.
- Individual Free, Plus, Pro and Ultra workspaces allow content to train Gamma's AI models by default, requiring an opt-out.
Grammarly
Pros
- Grammarly works across an impressive range of platforms including Chrome, Safari, Firefox, Edge, Windows, Mac, iOS, Android, Microsoft Word, and Google Docs.
- The plagiarism checker is built directly into the editor rather than being a separate export tool, a useful workflow for academic and content marketing use.
- Real-time grammar, spelling, and punctuation corrections remain reliable and are available even on the free plan.
- The Pro plan at $12/month billed annually unlocks full sentence rewrites, tone suggestions, and style clarity options at a competitive price point.
- Tone detection and brand voice features make it viable for enterprise teams managing content consistency across large organizations.
- Grammarly says it works across more than 500,000 apps and websites, making it one of the most broadly compatible writing tools.
Cons
- The free plan is significantly limited, though it does include tone detection and 100 AI prompts a month alongside basic grammar, spelling, and punctuation; most meaningful features still require a paid Pro subscription.
- Grammarly is now owned by Superhuman, which adds uncertainty about the product's long-term direction.
- Brand voice customization is heavily gated, with free users restricted to a single brand tone while unlimited options require an enterprise plan.
