Quick answer
Gamma - Gamma wins for most builders because its free tier gives broader creation, import, export, and website/document support, while SlidesGPT’s free tier is mainly basic presentation creation and sharing.
How the free tiers compare
Gamma and SlidesGPT both sit in the presentation-tools bucket, but they solve different parts of the workflow. Gamma is the broader product: on the free tier you can create presentations, docs, websites, social content, and images, import from PDF and PPTX, and export to PDF, PPTX, PNG, and Google Slides. It also gives 400 starter credits and requires no credit card. SlidesGPT is narrower on the free tier: you can create, view, and share presentations, but export, presentation mode, downloads, offline use, and other nicer workflow pieces sit behind paid plans. That makes SlidesGPT feel more like a lightweight try-before-you-buy tier for slide generation, while Gamma is closer to a usable free workspace for building and publishing multiple content types. If you only need to generate decks, SlidesGPT is simpler. If you want a free tool that stretches beyond decks and into distribution formats, Gamma is the better fit.
Gamma vs SlidesGPT free tier, side by side
| Gamma FTV 42 | SlidesGPT FTV 41 | |
|---|---|---|
| Free tier credits Gamma’s free tier is credit-based; SlidesGPT’s main free tier is feature-gated rather than credit-gated. | 400 starter credits at signup | Free forever with no cost |
| Cards per prompt Gamma increases to 20 on Plus, 60 on Pro, and 75 on Ultra. | Up to 10 cards per prompt | Not specified |
| Import sources SlidesGPT free tier does not list import support in the provided data. | PDF and PPTX import | Not specified |
| Export formats SlidesGPT exports are included starting with Pro. | PDF, PPTX, PNG, and Google Slides | Not available on free tier |
| Custom domains Only Gamma lists domain publishing quotas in the provided plans. | Up to 10 on Pro, 100 on Ultra | Not specified |
| Free credit card requirement Gamma explicitly says no credit card is required. | No credit card required | Not stated |
After you outgrow the free tier
Gamma’s first paid tier is Plus at $9 per seat per month, then Pro at $18 and Ultra at $90, so it is a straightforward per-seat ladder with more credits and higher creation limits as you move up. SlidesGPT’s main paid path is flatter for slide use: Pro is $7.49/month billed annually, then Pro XL at $22.50/month billed annually. SlidesGPT also has a separate usage-based API and a per-user Custom ChatGPT App at $19.99/user/month. For most small teams that just want better slide export, SlidesGPT is cheaper; for broader content creation and branding controls, Gamma costs more but covers more.
Cost at real usage
| Usage | Gamma | SlidesGPT |
|---|---|---|
| 1 seat, basic slide creation and sharing Paid behavior only matters once you need exports or other paid features. | Free (within tier) | Free (within tier) |
| 1 seat, export-capable workflow Gamma’s Plus adds more credits and branding removal; SlidesGPT Pro adds export, presentation mode, and downloads. | $9/mo | $7.49/mo |
| 5 seats using the core editor Gamma scales per seat; SlidesGPT’s listed Pro plan is per plan rather than per seat in the provided data, so this is not a strict apples-to-apples team cost. | $45/mo | $37.45/mo |

When to pick each one
Pick Gamma when…
- You want to create more than just slide decks, such as docs, websites, social posts, or images.
- You need import support from PDF or PPTX on the free tier.
- You want exports to common formats like PDF, PPTX, PNG, and Google Slides without paying first.
- You want to try the product without entering a credit card.
- You care about a broader content workflow, not only slide generation.
Pick SlidesGPT when…
- You only need fast AI-generated presentations and do not care about broader content types.
- You mainly want to create, view, and share decks with a very simple free workflow.
- You expect to move into a paid plan soon and want a clear slide-focused upgrade path.
- You may want API-based presentation generation, since SlidesGPT has a usage-based API offering.
- You are specifically interested in a ChatGPT-based branded slide app rather than a general content platform.
Bottom line
For the most common builder use case, Gamma is the better free-tier pick because it is usable for more than just deck drafting. You can start without a card, make presentations and adjacent content, import source files, and export in useful formats. SlidesGPT is attractive if your world is narrower and you mainly want slide generation, but its free tier is more constrained, with exports and other workflow features pushed into paid plans.
