The Best AI Slide Generators for Work and School in 2026

What is the best AI tool to turn lecture notes or a PDF into slides?

It depends on what has to happen to the deck next. Most tools now accept a file, so the real differences are how easily you can edit the result, what is free, and what else the source can become.

• You want a designed deck you can keep editing: Gamma. It takes a PDF, Word file, or PowerPoint, you can tell it to keep your text exactly as written, and it wins on design and hands-on editing. The Free plan is 400 one-time credits, and free exports carry a "Made by Gamma" badge.
• The deck has to stay inside PowerPoint or Google Slides: Plus AI. It builds native slides in both apps. There is no free plan, only a 7-day trial with a card, and document uploads start on its Pro plan.
• You already pay for Microsoft 365: Copilot in PowerPoint. It drafts from a prompt or a Word file, with speaker notes. A PDF source needs a work Copilot license.
• You want a free deck from several sources: Gemini Notebook (formerly NotebookLM), for users over 18, within its usage limits.
• You will present from your source and study or teach it afterward: Scholarly. It writes the talk first, so every slide gets speaker notes from your source, and the same upload can become a video lecture, a podcast, flashcards, or a quiz. The catch: Free makes one 10-slide deck for life, presented and shared by link, and in the paid PowerPoint export the slide visuals are images you cannot edit as text. If you need to restyle slides by hand, Gamma or Plus AI will serve you better.

We checked each tool on its own website on October 30, 2026, and we link pricing pages rather than quote every price. Disclosure: Scholarly is our product.

How to choose in one question

Ask what you will do with the deck after it exists.

• Restyle and edit it slide by slide: choose a tool with an editor built for that, such as Gamma, or one that works in native slides, such as Plus AI or Copilot.
• Present it as it is, with something to say over each slide: choose a tool that writes the talk from your source. Scholarly does this on every slide.
• Reuse the material: if the same notes also need to become flashcards, a practice exam, or a video, a slide-only tool stops at the deck. Scholarly and Gemini Notebook both go further from the same source.

One warning for any of them: a slide that says something almost right is worse than a blank one, because you will repeat it out loud. Read the deck against your source before you present. Google, for one, says plainly that its slide decks may contain visual or factual inaccuracies, and that applies across this category.

1. Gamma: best for design and hands-on editing

Gamma generates a deck from a prompt, or from your own material. Its import help page lists .pptx, .docx, PDF, Excel and CSV data, web links, and public Notion docs. You can import a file with its layout intact, or use it as source material for something new. You control how far Gamma strays from your words by saying so: Gamma suggests prompts such as "Keep my text exactly as written." Its agent can also ask about your goal and audience and show a plan before it builds.

• Free: new users get 400 credits. They do not refresh, and you can earn more through referrals. Credits are metered per slide and per image, so the number of decks you get depends on the deck.
• Exports: PDF, PNG, and PowerPoint, and Google Slides by uploading the .pptx. On the Free plan, PDF and PowerPoint exports carry a "Made by Gamma" badge. Speaker notes are included in PowerPoint and Google Slides exports.
• Paid: Plus, Pro, and Ultra, plus team plans. See Gamma's pricing.

Best for: a pitch, a class presentation you will polish, or anything where the look matters and you will edit by hand. We also wrote a full Gamma vs Scholarly comparison.

2. Plus AI: best inside PowerPoint and Google Slides

Plus AI is an add-in that works directly in PowerPoint and Google Slides. It says it creates native .pptx files and Google Slides presentations that are compatible with your existing templates, so you keep editing in the app you already use. You can start from a prompt, or upload a PDF, Word document, PowerPoint, or text file, and it can rewrite or reformat single slides.

• Free: none. Plans start with a 7-day trial with 1,000 AI credits, and a card is required.
• Paid: current prices are on Plus AI's pricing page. Its Basic plan does not list document uploads; Pro adds PDF, Word, and text uploads.

Best for: consultants, teams, and anyone whose final deck must be an ordinary, editable PowerPoint or Google Slides file. It is a poor fit if you want to try before entering a card.

3. Copilot in PowerPoint: best if your plan already includes it

Copilot in PowerPoint builds a deck from a prompt in PowerPoint on Windows, Mac, and iPad, and can use your organization's template. Microsoft's guide to preparing a presentation says a draft from a Word document comes complete with images and speaker notes.

The limit that matters for this question is the file type. Microsoft's FAQ says home users can build from a single Word file, while a work Copilot license adds PDFs. So with lecture notes in a PDF on a personal plan, export them to Word first or use another tool. Microsoft 365 Personal lists PowerPoint with Copilot, with usage limits, and Microsoft notes that Copilot may not appear if your subscription or organization does not include it.

Best for: people who already pay for it and work from Word documents.

4. Gemini Notebook: best free deck from several sources

Gemini Notebook (formerly NotebookLM) makes a Slide Deck from the sources in a notebook, with a choice of format, language, and length. You can present it in the app, or download a PDF or .pptx. It is available only to users over 18. To change slides you describe revisions and it generates a new deck, and Google says sources are not taken into account during revisions.

Best for: a free deck from material already in a notebook. Compare it with us in Scholarly vs NotebookLM.

5. Scholarly: best when you will present from your source, then keep using it

Disclosure: this one is ours.

Scholarly's AI slide generator starts from a PDF, notes, a Word or PowerPoint file, a spreadsheet, a web link, a Google Drive file, or a topic. On a PDF, you can pick the page range. It writes the talk first, then designs each slide in the shape the content calls for: a comparison, a process, a chart, a table, an equation, a timeline, or a figure taken from your PDF. It reviews the rendered slides and repairs problems such as clipped text before the deck reaches you. The talk becomes speaker notes on every slide.

• Free: one lifetime AI creation makes one 10-slide deck from one upload (up to 8 MB; PDFs read up to the first 32 pages). You present it and share it by link. It does not reset, and there are no downloads.
• Paid: Premium is $30 a month or $180 a year with 15 AI creation credits a week, and Laureate is $99 a month with 80. A deck is 5 to 30 slides, 15 by default, and the default model costs 1 credit. You can edit the slide text before the build, and ask for changes with Refine or the side chat afterward.
• Exports (paid): PDF, PowerPoint, Word, Google Slides, Google Docs, and print. The .pptx puts your notes in PowerPoint's notes pane. In PowerPoint and Google Slides, the slide visuals are images, so you cannot edit the text inside them. Word and Google Docs copies carry text you can edit.
• What it does not have: a template library, or a slide-by-slide design editor. You choose a preset (Full Deck or Exam Prep), a look, and dark mode, and steer with instructions.

The bigger advantage comes after the deck. The same source can become a narrated video lecture built on the same slide designs, a podcast, flashcards, or a practice exam. Start from PDF to PowerPoint for a PDF, notes to PowerPoint for notes, or text to presentation for an outline.

Best for: a lecture, an exam review, an SOP, or a report you will present and also need to learn or teach.

Other tools worth knowing

• Canva: Canva's help page says you can attach a PDF or Word file to give its AI more context. It also calls presentations a premium AI tool that counts toward your monthly AI usage, with access depending on your plan. It is the natural choice when your deck has to fit a brand or template you already keep in Canva.
• Beautiful.ai: layouts adjust automatically as you add content. Its pricing page lists a 14-day trial, a paid Pro plan, and editable PowerPoint export.
• Gemini in Google Slides: Google's own option for generating slides inside Slides, on the plans Google lists on that page.

Frequently asked questions

What is the best free AI tool to turn a PDF into slides?

Gamma if you want to keep editing (400 one-time credits, with a badge on free exports). Gemini Notebook for a free deck from your sources, within its usage limits, if you are over 18. Scholarly for one 10-slide deck with speaker notes, presented and shared by link, from its one lifetime creation.

Can Copilot in PowerPoint make slides from a PDF?

Only with a work Copilot license, according to Microsoft's FAQ. Home plans can build from a single Word file. Our Copilot in PowerPoint vs Scholarly comparison covers the PDF route in detail.

Is Plus AI free?

No. Plus AI offers a 7-day trial with 1,000 credits, and a card is required. Document uploads are listed from its Pro plan up.

Does Scholarly add speaker notes?

Yes. Every slide gets notes written from your source, and on a paid plan the PowerPoint download puts them in the notes pane for Presenter View.

Can I edit Scholarly's slides in PowerPoint?

Partly. You can edit the notes and rearrange the slides, but the slide visuals are images, so the text inside them cannot be edited there. If you need that, use the Word or Google Docs copy for the text, or choose Gamma or Plus AI.

Does AI make accurate slides from my notes?

It can get close, but read every slide against your source. Numbers, names, and diagrams are where to look first.

Don't stop at the deck

A deck helps you present. It does not make you understand or remember. If the material will come up again in an exam, a follow-up meeting, or a Q&A, send the same source into review: flashcards, a practice quiz, or clean notes.
