Gamma review

Gamma is the most complete prompt-to-deck tool on this list for a business user who wants a finished presentation fast. Its agent starts with an outline you can adjust, then builds the slides and lets you keep editing in a chat panel, with smart layouts or a freeform mode when you want manual control. Existing PowerPoint files and PDFs can be imported, and more than 25 connectors such as Slack, Notion and Dropbox pull in real content. Decks export to PowerPoint, PDF, PNG and Google Slides, so a draft can move into a company template afterwards. The free plan is generous enough to judge output quality, and the $9 Plus seat removes Gamma branding and allows up to 100 slides per prompt. The limits are on brand control and usage: custom branding and detailed analytics sit on the $18 Pro plan, and heavy users pay $90 for Ultra credits.
