Use Gamma for a new deck, Plus AI if the slides already live in Google

First-draft slides are a product choice, not a prompt trick. Gamma is $9/seat/year billed. Plus AI starts at $10/user/year billed. SlidesAI Basic is $0 with a tight credit cap.

OUR TAKE

Start with Gamma when you need a standalone prompt-to-deck. Stay in Google Slides or PowerPoint with Plus AI or SlidesAI. Use SlideSpeak when the source is already a PDF or Word file. Do not buy three slide seats for one outline.

Good fit

People who need a first-draft deck this week, not a design system

Poor fit

Teams that need a designer-owned template library as the source of truth

FAQ

What does Gamma Plus cost?
$9/seat/month billed annually ($108/year), 1,000 credits. Pro is $18/seat/year billed. Free exists with one-time credits. Checked 2026-10-19 on gamma.app/pricing.
Should I use Plus AI or SlidesAI inside Google Slides?
Plus AI if you want a composer inside the deck you already have (Basic $10 / Pro $20 per user/month billed annually). SlidesAI if you want the cheaper add-on path (Basic $0, Pro $10/user/month billed yearly). Checked 2026-10-20.
When is SlideSpeak the better first draft?
When the source is a PDF, Word, or Excel file you want turned into a native PPT. Free is about 3 presentations; Premium is $29/month. Checked 2026-10-22.
Do I still need ChatGPT or Claude?
Often yes — write the outline in an assistant, then generate slides in the slide tool. Do not pay two slide products to rewrite the same bullets.

A first-draft deck is a product choice: standalone prompt-to-deck, an add-in inside the file you already have, or document-to-PPT. Prompt quality matters after that.

Checked 2026-10-19 for Gamma; 2026-10-20 for Plus AI and SlidesAI; 2026-10-22 for SlideSpeak.

What not to do

  • Buy Gamma and Plus AI and SlidesAI for the same outline.
  • Treat Free Gamma credits as a monthly allowance. They are one-time on the snapshot we fetched.
  • Paste a 4,000-word script into SlidesAI Basic (2,500-character cap) and call the tool broken.
  • Trust a Help article over the live pricing page when they disagree. SlideSpeak Help still printed Premium Plus at $34; the public page said $40. We copy the page.

Outline first, slides second

Write the argument in ChatGPT or Claude, then generate. Two paid slide seats will not fix a missing headline. See ChatGPT vs Claude vs Gemini.

Best for / not for

Best for: a first-draft deck this week — a pitch, a class lecture, an internal one-pager.

Not for: a brand system that must come from a designer-owned template library; a team that needs every slide in a locked Figma file.

Buy one, then stop

  1. If you do not already have a deck file, try Gamma Free, then Plus at $9/seat/year billed if the credits die.
  2. If the deck already lives in Google Slides, try SlidesAI Basic, then Plus AI Basic if you want the heavier composer.
  3. If the source is a PDF, try SlideSpeak Free (three decks), then Premium if that is the weekly job.

Credits × seats is how teams overpay. A busy room burns Gamma Pro faster than a solo Plus.
