Gamma Tech, Inc. · 生產力
Gamma is an AI presentation tool that turns a short prompt, a pasted outline, or an uploaded file into finished slides, documents, or webpages. You describe what you need, answer a few questions, and the app handles layout, copy, and images for you. As an AI slide generator it skips the manual formatting that eats up most deck-building time. Gamma runs in a browser and has iOS and Android apps, with paid plans starting at $10 per month.
關於 Gamma
What Is Gamma
Gamma is an AI-native platform for building presentations, documents, webpages, and social posts without touching a blank slide. Founded in 2020 by former Optimizely colleagues and launched publicly in 2022, it set out to replace the manual work of slideware like PowerPoint and Google Slides. The shift is simple. Instead of placing every text box yourself, you give the tool a topic, and it drafts the structure, writes the copy, and lays everything out in a readable design.
The idea is to skip the formatting grind. A teacher outlining a lesson, a founder building a pitch deck, or a manager putting together a quarterly report can all start from a single sentence and edit from there. Gamma's slides resize themselves as content changes, so a paragraph that runs long doesn't wreck the layout the way it would in a fixed-size deck. It also converts existing files, including PowerPoint decks and URLs, into its own format. That's the entry point for a lot of people. Import your old deck, get a new look.
What holds it back is the credit system. AI generation, editing, and image work all draw on the same pool of credits, and the free plan hands out a one-time grant that never refills. The free tier also slaps a "Made with Gamma" badge on anything you export. Heavy users hit those ceilings fast, which is why most people end up on Plus or Pro. Gamma pricing reflects that split between casual and constant use, and the higher tiers are where the useful headroom lives. Is it worth paying for? For anyone making decks weekly, yes. Think of it as a strong presentation generator for first drafts, not an unlimited engine for free.
Getting Started
- Go to gamma.app and create an account with an email address or a Google sign-in. The free plan works without a card.
- Start a new creation and pick a mode: Generate to draft from a topic, Paste to format text you already have, or Import to convert a PowerPoint file or a URL.
- Describe what you're making. The agent asks a few questions about your goal and audience, or you can tell it to decide for you.
- Review the plan it proposes, adjust anything you want, then let it build the first draft.
- Edit with Agent, generate images, then export to PowerPoint, PDF, or publish as a website.

主要功能
Agent-driven creation
Gamma's agent starts from a conversation, not a perfect prompt. As an AI presentation maker, it takes a sentence and asks a few clarifying questions about your goal and audience before showing you a plan. That plan covers the story, the style, and the overall look. Nothing gets built until you approve it, which means you catch a wrong direction before it costs you a full generation. A rough idea is enough to start.
Slides that resize themselves
Unlike fixed-size slides, Gamma's cards grow and shrink with the content. Drop in a long paragraph and the layout adapts instead of overflowing or shrinking the text to an unreadable size. NotebookLM-style scrollable pages work the same way. That's a small thing until you've spent an hour fighting alignment. This removes the fiddliest part of slide editing, since you spend time on words rather than nudging boxes around.
Three ways to start a project
Generate drafts from a topic, Paste reformats text you already wrote, and Import converts an existing PowerPoint, document, or URL. Which one you pick depends on how much you've already done. The Import path is the practical one for people with work elsewhere. You keep your content and get a new layout, rather than starting over.
AI image and animation generation
Gamma generates images inside your content from a text prompt, with basic, advanced, premium, and ultra image models depending on your plan. You can set a style to keep visuals consistent across a deck, and the Ultra plan adds AI animations. Image work draws credits. AI animations sit behind the Ultra tier. Plan accordingly if visuals are central to your work.
Agent as a full editor
After the first draft, Agent stays with you. Ask it to refine one slide, restyle the whole deck, pull in links and screenshots, or research a topic and add citations. A small request like "shorten this section" only touches that section, without regenerating everything. Not a rebuild every time. It also works in the mobile apps.
Publishing to sites and custom domains
Gamma isn't limited to decks. You can publish multi-page sites, and Pro allows up to 10 custom domains while Ultra raises that to 100. Password protection and headers and footers are available on paid tiers. Suddenly a presentation is a shareable web page, and you didn't open a separate site builder.
The Gamma Generate API
Gamma's API v1.0 became generally available in late 2025 and lets you create presentations, documents, webpages, and social posts from code. It suits automation through tools like Zapier, Make, or n8n, and backend integration for apps that generate decks at scale. Access needs a Pro, Ultra, Team, or Business account. The API key uses the X-API-KEY header.
優缺點
優點
- Gets you from a rough idea to a presentable draft fast, with layout and copy handled for you.
- Import converts existing PowerPoint decks and URLs, so you don't rebuild work you've already done.
- Self-adjusting slides cut the time you'd normally spend fixing overflow and alignment.
- The Generate API supports automation and building deck creation into your own product.
缺點
- The free plan gives 400 one-time credits that never refill, so it runs out quickly, and free exports carry a "Made with Gamma" badge.
- API access needs Pro or higher, so automation isn't available on Free or Plus.
- AI animations are locked to the Ultra plan, which puts visual extras out of reach on cheaper tiers.
- Every AI action draws credits, so heavy image or generation use burns through a monthly allowance faster than the headline number suggests.
常見問題
Gamma creates presentations, documents, webpages, and social posts from a prompt or an imported file. People use it for pitch decks, reports, lesson slides, and landing pages, mostly to skip manual design work rather than to replace a full design suite.
