Gamma vs Grammarly

Gamma is an AI-native tool that turns a prompt, outline, notes or an uploaded document into a finished presentation, document, social post or one-page website. It was founded in San Francisco in 2020 by Grant Lee, Jon Noronha and James Fox, and in November 2025 it raised a $68 million Series B led by Andreessen Horowitz at a $2.1 billion valuation, saying it had passed $100 million in annual recurring revenue and 70 million users.

Instead of fixed slides, Gamma uses flexible cards that resize to content, with themes, AI-generated or stock images, charts, embeds and analytics on who viewed what. You can edit with an AI chat, translate content, export to PowerPoint, Google Slides or PDF, or publish as a web page on a custom domain. AI actions spend credits: the free plan gives 400 once, Plus adds 1,000 a month and removes the Gamma badge, Pro adds 4,000 credits, the API and custom domains, Ultra unlocks the most advanced models, and Business adds SSO and shared themes per seat.

Gamma suits founders, marketers, consultants and educators who need good-looking decks fast and care more about speed than pixel control. Designers will find layout control limited, exports to PowerPoint can need cleanup, and heavy users burn through credits. Canva offers far more design freedom and templates, Komodo Decks targets polished business presentations, and ChatGPT can draft outlines but not designed decks.

Prices on gamma.app vary by visitor location. Start on free credits, then pick Plus unless you need the API or custom domains.

Grammarly is an AI writing assistant founded in 2009 in Kyiv, Ukraine, by Max Lytvyn, Alex Shevchenko and Dmytro Lider, now headquartered in San Francisco. It works wherever people write, through browser extensions, desktop apps for Windows and Mac, mobile keyboards and integrations with tools such as Google Docs, Microsoft Word and Outlook, checking text in real time as you type.

Beyond spelling and grammar, Grammarly flags clarity, conciseness, tone and engagement issues, rewrites whole sentences, adjusts formality, checks plagiarism and citations, and generates or edits text with AI prompts and agents. Business plans add company style guides, brand tones, snippets for reusable text, analytics and SSO. The free plan covers core corrections and a limited number of AI prompts; Pro adds full rewrites and more AI usage; Enterprise adds admin controls and security reviews.

After acquiring Coda in late 2024 and the email client Superhuman in 2025, the company began building a broader AI productivity suite, and in late 2025 it adopted the Superhuman name for the company while keeping Grammarly as a product brand. Grammarly remains strongest in English; in September 2025 it added beta support for Spanish, French, German, Italian and Portuguese, but Turkish is not among the supported writing languages. AI features built into Google Docs and Microsoft 365 cover basics for many users, and QuillBot is a popular, cheaper option for paraphrasing.
