Slides Orator

Slides Orator is an AI narration tool that turns PDF slides into talking, question-answering presentations. SlidesOrator converts uploaded PDF decks into narrated, interactive presentations hosted by a 3D avatar, with real-time audience Q&A, question collection, document summaries and mini quizzes.

SlidesOrator is an AI presentation layer that sits on top of decks you have already built. The homepage is explicit about this: the product does not generate your slides, it brings them to life. You upload a PDF deck, the platform writes a narration script and voices it, and a 3D avatar presenter carries the talk on your behalf in front of audiences of any size. Slides, images, videos and 3D objects can all appear inside the presentation, which then plays in a browser and is shared through a simple link. The feature set goes past narration. Real-time Q&A lets the audience ask questions during the session, and proactive questioning has the AI pose its own. A document summary panel condenses the material, and a mini quiz tests comprehension of the uploaded document. Audience questions can be collected for later review, and Q&A data is analyzed anonymously to produce reports on what the audience asked and where confusion clustered. A speech copilot mode rounds this out: it simulates a presentation, regenerates narration on the fly and delivers it through the digital assistant so a speaker can rehearse or refine wording. The tool is aimed at people who present the same material repeatedly or to distributed audiences. The site names three core use cases: education, where teachers turn static slides into narrated lessons; corporate training, where sessions stay consistent across locations and time zones; and product introduction, where a talking avatar answers visitor questions at a stand or on a landing page. Reviewing material after class and rehearsing a speech are listed as additional scenarios. Under the hood, SlidesOrator describes its approach as ALUI, an avatar plus LLM plus user interface. It uses 3D avatar rendering through WebGL2 and a game engine for playback and multimodal content, chosen because real-time chat can run at low cost without the heavy upkeep of alternatives. End-to-end speech handling covers text-to-speech and speech-to-speech so users skip the technical setup. Compared with avatar video generators that export a fixed MP4, the browser-based interactive format is the differentiator.
