Turn any text, PDF, image or book into lifelike AI speech
Voices trained on large language models deliver lifelike delivery, while Content Aware voices read the text and adjust tone to fit the material.
Speak in over 90 languages and create a custom multilingual AI voice by uploading or recording your own.
Read PDFs, Word documents, ePub, web pages and images, and scan physical books with the built-in OCR camera scanner.
Turn long readings into AI podcasts, get instant recaps, analyse screenshots and equations, chat with your document and generate practice quizzes.
Private AI that turns your organization's knowledge into adaptive training
Upload documents, recordings, wikis, webinars or web pages and Slice automatically assembles them into complete, SCORM-compliant courses — the vendor claims roughly 80% less content-creation time.
Subject-matter experts simply talk or upload recordings; Slice transcribes, structures and makes that tacit knowledge permanently searchable so it is not lost when people leave.
The platform detects a learner's role and current knowledge level and continuously adjusts a personalized path instead of serving one fixed curriculum to everyone.
A single private AI assistant answers questions, launches full courses inside the chat, runs simulations and coaches learners through to mastery.
