Quick answer
SlidesGPT - SlidesGPT wins for most builders because its free tier is broader for everyday sharing and its paid path starts much cheaper, while Autoppt is better only if you need lots of AI slide-generation tooling inside a presentation-first workflow.
How the free tiers compare
The two free tiers solve different problems. Autoppt is a presentation-maker with a small but fairly broad set of AI utilities: slide generation from prompts and files, summarizer, writer, mind map, PDF, chat, and online editing. The free plan is credit-limited, so it is more of a trial than a workspace. SlidesGPT is narrower on the free side, but its free plan is simpler and more usable for sharing because it lets you create, view, and share presentations forever at no cost. Where the products really separate is after free: Autoppt’s first paid plan is $19.99/month, while SlidesGPT starts at $7.49/month billed annually. If you mostly need to make and distribute decks, SlidesGPT is the cheaper path. If you want more AI workflows inside the app, Autoppt gives more surface area.
Autoppt vs SlidesGPT free tier, side by side
| AutopptFTV 32 | SlidesGPTFTV 41 | |
|---|---|---|
| Free slide generationsAutoppt gives only four free generation tries across methods. SlidesGPT's free tier is more about usage of the core app than a stated generation quota. | 4 AI slide generations total | Create and view presentations; no explicit free generation cap shown |
| Template replacement | 1 free use | Not listed on free tier |
| AI summarizerAutoppt includes summarizer tools in free; SlidesGPT free tier does not mention them. | 1 use plus 1 chat use | Not listed on free tier |
| AI writer / chat / mind map / PDFAutoppt's free credits are split across several AI tools. | 2 writer uses, 5 basic chat uses, 15 mind map uses, 20 AI PDF uses | Not listed on free tier |
| Editing and sharingBoth support core presentation workflows, but SlidesGPT states sharing directly in the free tier. | Online slide editing | Create, view, and share presentations |
| Credit card requirementDo not assume either way because the field is absent for both. | Not stated in the input | Not stated in the input |
After you outgrow the free tier
Autoppt uses flat monthly pricing for its consumer plans: $19.99/month for Pro, then $29.99/month for Unlimited, with a $16.66/month annual equivalent and a $299.99 lifetime option. SlidesGPT starts lower: $7.49/month for Pro billed annually, $22.50/month for Pro XL, then a per-seat Custom ChatGPT App at $19.99/user/month, plus a usage-based API and custom Enterprise pricing. For typical small-team usage, SlidesGPT is cheaper at the entry level; Autoppt gets cost-effective only if you need its broader AI feature set or prefer the unlimited plans.

When to pick each one
Pick Autoppt when…
- You want a presentation tool with multiple AI features beyond deck generation, like summarizing, writing, mind maps, PDF handling, and chat.
- You expect to use imported files and prompt-to-slides workflows often and want one app focused on that pipeline.
- You are fine treating the free plan as a short trial and are evaluating whether to upgrade for heavier monthly usage.
- You want unlimited AI slide generation only if you are willing to pay $29.99/month or buy lifetime access.
Pick SlidesGPT when…
- You need a free forever tier for creating, viewing, and sharing presentations without paying.
- You care about the cheapest first paid step for export, offline editing, printing, or presentation mode.
- You want a simple path from free to paid with a low entry price at $7.49/month billed annually.
- You are building around API generation and want a usage-based option with 100 presentations/month free.
- You want a branded or team-oriented workflow, especially the per-user ChatGPT app option.
Bottom line
For most builders, SlidesGPT is the better free-tier choice because it gives you a genuinely usable forever plan for create, view, and share, and its first paid tier is much cheaper. Autoppt makes sense if your workflow depends on more AI steps inside the product, such as summarizing, writing, mind maps, PDF work, or repeated slide generation. If you only need to make and distribute decks, SlidesGPT is the cleaner and cheaper path. If you want a presentation-focused AI toolkit, Autoppt is the stronger upgrade candidate.
