Slides by AI turns a topic into editable AI slides and a PowerPoint download in minutes. Free to try — no signup required.
Practical guides for picking tools and shipping decks faster — AI presentation makers, PowerPoint generators, and free-tier rules.
Enter a topic or tap Pitch / Lesson / Report for a ready-made example.
Get a structured deck with titles and bullets you can edit in place.
Export a PPTX file for PowerPoint, Google Slides, or Keynote.
Blank PowerPoint files punish you with empty masters and decision fatigue. An AI slides generator drafts the narrative first — section order, titles, and bullets — so you spend time editing claims instead of staring at Slide 1. Slides by AI keeps that draft fully editable and exports a standard PPTX you already know how to finish.
Free visitors get 1 generation per day (up to 5 slides, watermark on export). Paid plans from $9/month include 30 presentations per month, up to 12 slides, and clean files. Re-exporting after you edit text does not spend another credit.
If you are comparing products, start with our AI presentation maker guide for commercial intent, the AI PowerPoint generator for .pptx-focused searches, or the PPT AI explainer when you still need the category basics.
Pitch drafts, classroom lessons, weekly business reviews, workshop agendas, and status updates all share a pattern: you know the topic, you need structure fast. Paste a brief that names audience and goal. Generate. Cut filler. Add proof. Download. Finish charts in PowerPoint when the story is solid.
Students and indie founders often stay on the free AI presentation maker path; teams that ship client decks weekly usually need Pro for watermark-free volume. See Slides by AI vs Gamma if your fork is hosted web decks versus PPTX files.
Template packs give you pretty masters and empty boxes. An AI slides generator gives you a first narrative: opening, problem, proof, ask — or whatever your brief implies. You still choose colors and charts, but you stop inventing the outline from scratch every Monday.
Templates win when brand kits are locked and designers own every pixel. Generators win when the bottleneck is thinking, not theming. Most operators use both: draft here, then drop the PPTX into a company theme.
If you are still learning the category, read what PPT AI is and how it works. If you are buying, use the best AI presentation maker checklist and run the same brief on two tools before you commit budget.
Name the audience and the decision you want them to make. Add a timebox (“8 minutes”, “one class period”). List must-include sections if you have them. Vague prompts produce vague decks; dense briefs produce outlines you can edit in minutes instead of hours.
After you generate, cut filler before you decorate. Add one evidence line per claim. Re-download — edits do not spend another credit. Save briefs that worked so tomorrow’s free run starts from a proven pattern.

Founders drafting a first pitch, teachers building a lesson skeleton, and operators writing a weekly review all benefit: the bottleneck is structure, not pixel-perfect design. Paste a brief, get titles and bullets, then finish brand and charts in tools you already use. That is the job this AI slides generator is built for.
Skip it when legal or compliance teams must own every word before anyone sees a draft, when your company forbids sending content to third-party models, or when the deck is already outlined and you only need a designer. In those cases, a locked template or a human designer is the faster path — generators shine before the outline exists.
Scenario check: investor update with real ARR? Generate the story beats, then replace every number yourself. Classroom quiz with answer keys? Let AI draft vocabulary slides; write the answers offline. Client workshop with proprietary research? Sanitize the brief, generate the agenda, keep the data in your own files. Matching the tool to the risk keeps AI slides useful without overselling what a model can invent.

AI slides are presentation decks drafted by a language model from a short topic or brief. You get structured pages with titles and bullets you can edit, then download as PPTX.
Enter a topic, pick an example chip if you like, and generate. You get a 5–12 page outline (plan-dependent), edit titles and bullets, then download a PowerPoint file.
Yes — 1 free generation per day (up to 5 pages, with watermark). Paid plans from $9/month include 30 presentations/month and remove the watermark.
Yes. Every slide title and bullet is editable in the browser. After you change text, Download rebuilds the PPTX from your edits without using another generation credit.
A standard .pptx file you can open in PowerPoint, Google Slides, Keynote, and most other presentation apps.
Free runs are capped at 5 pages. Paid plans allow up to 12 pages per presentation.
Yes. Free exports add a final watermark slide. Paid plans remove it.
Be specific: audience, goal, and context. Pitch, lesson, and report chips are good starting points for AI slides that stay focused.
Templates give you empty layouts. An AI slides generator drafts the narrative — titles, section order, and bullets — so you edit claims instead of inventing the outline. Most teams still apply a company theme after download.
Skip generation when you cannot paste the topic into a third-party model, when every word must be pre-approved, or when you already have a finished outline and only need design. Use a locked template or a designer instead.
