A lightweight text-to-slides add-in for Google Slides and PowerPoint: paste notes, a topic or a document and it generates a starter deck. Genuine free plan, low price, huge install base — thin on design and editing.
SlidesAI does one thing and keeps it simple: you paste in text — notes, an article, a topic, a document — and it turns that into a slide deck inside Google Slides or PowerPoint. It is not trying to be a design studio or a full presentation app. It is a fast, cheap text-to-slides generator that lives where you already keep your slides, and judged as exactly that, it is genuinely useful.
The whole product follows from that narrow scope, for better and worse. Because it is lightweight, it is inexpensive, easy to learn, and has been installed millions of times. Because it is lightweight, it is also thin on design control, brand sophistication and deck editing — it produces a first draft and largely leaves the polishing to you and to Google Slides. And unusually, its plans are metered in presentations per year with a character limit per deck, rather than open-ended use — which is the constraint most likely to pinch a frequent user.
It is one of the AI slide generators and works as an add-in in both Google Slides and PowerPoint, which makes it a lightweight AI PowerPoint tool as well.
It has a genuine free plan — 12 presentations a year — so you can try the real thing before paying, which not every rival allows.
The workflow is as simple as it gets: paste text, generate, done. For someone who already has the content and just needs slides around it, there is almost nothing to learn.
Reach and price. With 15M+ installs it is one of the most widely used tools in this category, and at $10 to start it is among the cheapest, with native editable output into Slides or PowerPoint.
Basic is free: 12 presentations a year, 1,000-character input. Pro is $10/month (or $120/year): 120 presentations a year, 6,000-character input, and document upload. Premium is $20.83/month (or $250/year): unlimited presentations, 12,000-character input, and document upload. The annual presentation quotas and character caps are the real limits to watch — a frequent presenter can outgrow Pro's 120-a-year, and a long source document bumps into the character ceiling.
Two details could not be confirmed from primary sources when this was checked — whether the free tier applies a watermark, and whether it offers a true brand kit — so those fields are left blank here rather than guessed. Confirm on SlidesAI's own site.
People who regularly need to turn text they already have into a straightforward deck, inside the tools they already use, without paying much or learning anything new. Students, teachers, and anyone whose thought is "I have the content, I just need slides" are the sweet spot.
If you want polished, on-brand design, or the ability to restructure and edit existing decks with AI, this is too thin — Plus AI does the editing job far better, and Gamma or Beautiful.ai do design better. Heavy users should check the per-year quotas before committing.

An AI presentation maker that turns a prompt or a pasted document into a finished-looking deck in about a minute. A standalone web app — great free plan for on-screen decks, but clean PowerPoint export and branding are paid.
A generative-AI-first presentation maker — "ChatGPT for presentations." You describe a deck and it builds the whole thing, then you refine conversationally. Genuine free plan; fast, but a thin independent track record so far.
A guided, opinionated AI deck builder for non-designers that generates the slides plus delivery extras — speaker notes, audience Q&A, lead-capture forms, voiceover and hosting. Cheap entry point; no true free plan.
Plus AI, SlidesAI and Microsoft Copilot compared — AI that generates slides inside PowerPoint and Google Slides, with no export step. Which add-in fits your workflow.
The best AI presentation tools for education — which are genuinely free, which handle research and lesson slides, and how to use them without paying a cent.
