A SlidesAI alternative that is a full editor, not only an add-on

Why people look for a SlidesAI alternative

SlidesAI’s job is narrow and useful: you already live in Google Slides or PowerPoint, and you want a prompt or a block of notes turned into slides without leaving that file. People still shop for a SlidesAI alternative when:

• The quota is the product. Every plan meters presentations, characters of input, and AI credits per year. Basic allows 12 presentations a year — one a month — and 1,000 characters per presentation, roughly a long email. If you generate a lot, you are always watching the meter. If you generate rarely, you may not want a subscription whose only job is generation.
• The editor is still Google or Microsoft. SlidesAI does not replace the deck format. The result is a Slides or PowerPoint file, and anything you export afterwards is whatever those apps export — not Reveal.js.
• They outline in text, not in a sidebar. Writers and developers often think in headings and bullets. An add-on that paints into a .pptx or Google Slides file is a different way of working.
• The prices online disagree. Older numbers still circulate from SlidesAI’s structured data and from roundups. The on-page yearly display is the one to trust; it is what we cite below.

What AI Slide Generator is

AI Slide Generator is a Reveal.js presentation builder. You write (or generate) slides in our editor. AI is optional.

• Free ($0): unlimited manual decks and slides, all templates, freeform canvas, export PDF, PPTX, and HTML. No AI. No credit card.
• Pro $15/month: 100 AI generations a month, Alie, AI content suggestions, AI images, email support. Yearly is 20% off ($12/month billed yearly, $144/year).
• Unlimited $39/month: unlimited AI, priority processing, advanced models, API access, priority support. Yearly is 20% off ($31.20/month billed yearly, $374.40/year).

We do not sell a Google Slides or PowerPoint add-on, and we do not install into either app. We do not offer Team, Enterprise, Institution, SSO, or real-time multiplayer editing.

Comparison (honest)

Sources: slidesai.io/pricing Individual yearly tab, visible text (29 Sep 2026), sold via Paddle; aislidegenerator.ai/pricing. We deliberately ignore the structured data on SlidesAI’s pricing page: its FAQ answers still say $8.33 and $16.67 a month, its Offer entries say $12 and $25, and it carries a star rating. None of that matches the visible yearly display, so none of it is cited here. Recheck their page the day you rely on it.

SlidesAI’s strengths

Zero new editor to learn. If the org already lives in Google Slides, an add-on is the path of least resistance. No new file type, no “can you re-send that as a PPT”, no migration conversation with IT. Plus AI is the heavier, per-seat version of the same idea; SlidesAI is often the lighter-quota one.

A real free tier with AI. Basic includes a small yearly AI credit pool. Our Free has no AI — only manual decks. If “free AI once in a while” is the requirement, SlidesAI Basic answers it and our Free does not.

Document upload on paid plans. Pro and Premium take documents as the source. We ask you to work in our editor, or paste.

Paddle handles billing. Invoicing, tax, and refunds run through a payments company as Merchant of Record.

Where we are different

A full editor, not a sidebar. Reveal.js is the product, and HTML export is first-class on every plan.

No yearly presentation cap. Free is unlimited manual presentations. SlidesAI Basic is 12 a year; Pro is 120 a year. Editing and export are never metered here, and there is no character ceiling per deck.

AI sold as a plan, not a credit bag. Pro is 100 generations a month; Unlimited is uncapped AI plus API. Their Pro starts lower at $10/mo billed $120/year, so do not read this as “we are cheaper” — compare the limits, not only the number.

We are worse at staying inside Google Slides. If leaving the host app is forbidden, stay on SlidesAI (or Plus AI).

Who should stay on SlidesAI

• You must author in Google Slides or PowerPoint.
• A small yearly AI quota is enough — students, occasional decks.
• You want to upload a document as the source.
• You need a team or institution licence.

Who should try AI Slide Generator

• You want Reveal.js / HTML talks you can self-host.
• You want unlimited manual editing for $0, with no card and no yearly deck count.
• You want API access on a published Unlimited plan.
• You are fine rebuilding in a dedicated editor.

Switching

There is no importer for SlidesAI, Google Slides, or PowerPoint decks. Export PPTX or PDF from the host app, rebuild the outline here, or generate a first pass on Pro. Keep your SlidesAI plan until you are sure; cancelling it goes through their billing (Paddle), not ours.
