Decktopus vs Gamma

Decktopus

• Consultants, agencies and small firms that need client decks without a designer
• Presenters who want to rehearse and take practice questions before a talk
• Redesigning an existing presentation file while keeping its content

Gamma

• Turning a topic, notes or an existing file into a first-draft deck
• People who would rather describe changes than arrange slides by hand
• Teams automating deck creation through the API, Zapier, Make or n8n

Decktopus

• There is no ongoing free plan: new accounts get 15 AI credits, about 3 slides, and further use needs a paid plan.
• Brand Kit, the team workspace and custom domains are Business features; Pro is a single-person plan.
• An internet connection is required: the pricing FAQ says presentations cannot be created, edited or viewed offline.
• The pricing FAQ states that all purchases are final and non-refundable.

Gamma

• Plus, Pro and Ultra prices are shown only on Gamma's pricing page; its help center gives the Business price, $40 per member per month billed annually.
• Free-plan AI credits do not refresh: accounts start with 400 and earn 200 more per referral. Paid plans get monthly credits, from 1,000 on Plus to 20,000 on Ultra.
• API keys, detailed viewer analytics, password protection and custom domains start at the Pro plan, and Ultra is sold on monthly billing only.
• The mobile apps are in early access, limited to the US and Canada, and edit only through the agent, with no manual editing.

Decktopus

AI deck generation

Entering a topic or uploading a file produces a full presentation with structure, content and design. Generating a slide costs 5 AI credits from the monthly allowance.

Prompt-based editing

Any slide can be changed by describing the edit in plain language instead of adjusting the layout by hand. Each AI edit costs 5 credits, shown before the change is applied.

Loop delivery coach

Four AI agents gather the context, build a narrative with speaking notes, simulate audience questions and run a live rehearsal that measures pacing and filler words.

Brand Kit

On Business plans, a brand kit built from a website URL applies company colors, fonts and style to every deck a team generates.

Live links and viewer tracking

A shared link always shows the latest version of a deck. Tracking shows who opened it and how long they spent on each slide, and an email gate turns viewers into contacts.

ChatGPT app and MCP server

Decktopus can be called from inside ChatGPT, and a remote MCP server connects it to Claude and other MCP-ready assistants to return a presentation or carousel.

Gamma

Generate, paste or import

Three ways to start: generate a draft from a topic, paste existing text for Gamma to lay out, or import a PowerPoint, Word or PDF file or a URL to be restyled.

Agent

The agent asks about goal and audience, shows a plan to approve, then researches, writes, designs and adds images. Changes are requested in plain language in the same chat.

Present mode

Decks are presented full screen or in a tab, with a presenter view for private speaker notes, a spotlight mode that highlights the current block, and a follow link viewers can use to keep pace.

Export and import

Exports to PDF, PNG and PowerPoint, with tables kept editable in PPTX. Imports accept PowerPoint and Word files up to 200 MB and PDFs up to 100 MB.

Sites and custom domains

A gamma can be published as a website. Pro can publish up to 10 multi-page sites to custom domains, and Ultra and Business up to 100.

API and connectors

A REST API, generally available since November 2025, creates gammas from text or templates on Pro and higher plans. ChatGPT, Claude and Slack connectors work on every plan.
