Slice Knowledge is a private, deployable AI environment that converts internal documents, recordings and expert know-how into SCORM-compliant courses, then delivers them through a single AI agent that answers questions, runs practice simulations and personalizes each employee's learning path.
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.
