Audiolizer

Audiolizer is an academic research tool that turns dense research papers into listenable audio narratives. Audiolizer converts research papers from PDF or arXiv links into narrated audio, explaining formulas, tables and figures in plain language and splitting papers into navigable chapters.

Audiolizer is a web tool that converts academic papers into narrated audio. The starting point is a PDF upload or a pasted arXiv link, and the output is a spoken version of the paper that can be played in the browser or exported to podcast platforms. The stated aim is to move reading into commuting, exercise and other hands-busy time, cutting screen time and the fatigue that comes with working through long technical documents. The feature set is built around comprehension rather than plain text-to-speech. Audiolizer's AI reviews formulas, tables and figures and turns them into spoken explanations, which matters for papers in machine learning, physics or statistics where the meaning often sits in an equation or a chart. A knowledge level control adjusts how much background the narration assumes, running from beginner to expert. Chapter detection splits the audio into navigable sections, references are skipped automatically, and listeners can jump to the part of the paper they care about instead of hearing the whole thing. In practice the workflow is short: upload or link the paper, wait for processing, then find the result in a personal gallery or push it to Spotify, Apple Podcasts or YouTube Music for listening elsewhere. Narration quality is split between a standard voice on the free tier and a premium voice on the paid plan, and chapter navigation is likewise described as basic on the free tier and advanced on the paid one. Audiolizer sits between reference managers and general text-to-speech readers. It does not organize a literature library or take notes, and it is narrower than a full document reader, but it handles the specific job of making a technical paper understandable by ear. The audience is researchers, students, and anyone working through academic literature who would rather listen than read.
