Free AI transcription and audio enhancement for video, podcasts, and meetings
Convert uploaded files, public media links, or live recordings into accurate editable text, with automatic language detection across a wide range of languages.
Speakers are labelled automatically so you can tell who said what, and clicking any line jumps the player to that exact moment.
Noise reduction, echo removal, an audio enhancer, an audio extractor, and trimmers let you improve and cut source audio before or after transcribing.
Choose meeting, creator, study-note, podcast show-notes, or legal-style summary structures, and keep transcripts plus summaries stored and searchable.
Interactive presentation platform with live polls, quizzes, and Q&A built into your slides
Build interactive activities into the presentation itself; the audience joins with one QR code, no app and no login, and questions rise by audience upvote.
Describe your topic in a sentence and let Prezi draft a presentation, or bring in PowerPoint, Google Slides, Canva, PDF, Word, or ChatGPT-generated slides that keep their formatting.
Generate timelines, mind maps, infographics, and simulations from your material and drop them into the flow of the presentation.
Share one link so people can review with flashcards and self-tests, a podcast, narrated video, transcript, or the full interactive presentation.
