Category	Productivity	Productivity
Pricing model	freemium	freemium
Headline pricing	Free to download; Perplexity Max at $200/mo unlocks the highest limits	Free (400 credits) + Plus $10/mo, Pro $20/mo, Ultra $60/mo (annual billing) — confirm current rates on site
Free tier	Yes. The browser is a free download and works without a paid Perplexity plan. The agentic features and the higher query limits are what a subscription buys.	400 AI credits at signup — enough to build and iterate on a few full decks before deciding. Note: month-to-month billing costs more than the annual rates shown, and Gamma adjusts tiers fairly often, so confirm current numbers at gamma.app/pricing before quoting them.

Productivity · freemium

✓Assistant operates on the page you are already viewing instead of in a separate window with no context
✓Chromium base keeps most Chrome extensions working, which removes the usual dealbreaker when switching browsers
✓Import carries bookmarks, passwords, cookies, history and extensions across in one step
✓Free to download with no subscription required to start using it
✓Background Assistants give paying users parallel agentic tasks with confirmations gathered in one place

×Browser-agent limits are published only as relative claims, so no tier states how many agent queries you actually get
×The features most people want the browser for, Background Assistants and Email Assistant, sit behind the $200/mo Max tier
×Switching browsers is a bigger commitment than installing an extension, and profile migration is never fully clean
×An assistant with access to your logged-in sessions is a meaningful trust decision that a chat window in another tab does not require

Productivity · freemium

✓Prompt or uploaded file to a presentable, on-brand artifact in roughly a minute
✓Four output formats — deck, document, hosted webpage, social graphic — from one set of cards
✓Import-and-redesign handles existing PowerPoint, PDF, and Slides files, which is how most teams actually get value from it
✓Per-card view analytics on shared links, uncommon outside dedicated sales-enablement tools
✓Free tier is large enough to evaluate on a real project rather than a toy one

×PowerPoint export flattens nested cards and interactive embeds — the exported file is noticeably worse than the hosted version
×Little pixel-level layout control; the guardrails that make it fast are the same ones that frustrate designers
×Copilot in PowerPoint and Gemini in Google Slides are bundled into subscriptions many buyers already hold, making Gamma a second line item for deck generation
×Credit-metered generation and the premium image/video models sit behind the top tier, so heavy or media-rich use gets expensive fast
