In their own words
ChatSlide
ChatSlide turns documents, topics, and research into presentations using AI generation and summarization. Users can upload notes or files, import material from supported sources, or enter a topic; the platform arranges content into slides with layouts, images, and speaker notes. Its 19 editing tools can add examples, rewrite content by grade level, and refine slides. Upload formats include PDF, DOCX, PPTX, TXT, and images; content sources also include URLs, YouTube, PubMed, OpenAlex, and ClinicalTrials.gov. Presentations can be exported as PowerPoint, PDF, or Keynote, and decks can be rendered as narrated videos with AI voiceover in more than 30 languages. The free tier includes 100 credits and PDF export; PowerPoint export is paid, and no credit card is required to start. Paid plans list project limits from 30 to 60 slides. Presentations are private by default, and free-plan uploads may be deleted after up to 30 days.
