What Is Gamma?Gamma 是什么？
Gamma is a US-built AI visual-communication platform: type a prompt, paste notes, or import a file — its AI drafts an outline first, then builds a designed presentation, document, website, or social post. Official site: gamma.app.Gamma 是美国公司推出的 AI 视觉表达平台：输入一句话、粘贴一段笔记或导入文件，它先让 AI 起草大纲，再自动生成设计好的演示文稿、文档、网页或社媒帖。官网是 gamma.app。
Unlike classic slide templates, Gamma is narrative-driven: it uses cards instead of slides, with modern design and interactive web publishing. Export to PPTX, PDF, PNG, and Google Slides; import old PowerPoint/PDF files to restyle them. Workspaces add custom branding, fonts, domains, and analytics.和传统 PPT 模板最大的不同是叙事驱动：Gamma 用「卡片」代替幻灯片，设计现代、支持交互式网页发布。做完可以导出 PPTX、PDF、PNG 和 Google Slides，也能把旧的 PowerPoint/PDF 文件导入进来重新排版。工作区还支持自定义品牌、字体、域名和分析。
The free plan grants 400 starter credits (one-time, non-refilling, no credit card) — enough for several decks. Paid tiers Plus, Pro, and Ultra run $9, $18, and $90 per seat per month on annual billing, with monthly-refilled credits and Gamma branding removed. Check the official site for current pricing.免费版赠送 400 起步积分（一次性、不刷新、无需信用卡），足够做几套演示文稿试手。付费版 Plus、Pro、Ultra 分别为 $9、$18、$90/座/月（年付价），积分按月刷新、去除 Gamma 品牌水印。价格以官网为准。
Gamma is the fastest way I know to go from a rough idea to a presentable deck — the outline-first flow and modern card design make even plain notes look intentional. The free 400 credits are a genuine trial, not a teaser. For teams, Pro branding controls and API matter more than the extra credits; confirm the seat pricing on gamma.app before committing.
从粗糙想法到能拿出手的演示文稿，Gamma 是我见过最快的一条路：先大纲后设计的流程加上现代卡片风，连潦草笔记都能显得有条理。免费的 400 积分是真试用不是噱头。团队用户更该看 Pro 的品牌控制和 API 而不只是积分，买单前先去 gamma.app 确认座位价。
