Your personal AI tutor for every subject, from notes to exam day.
Upload your notes, slides or past papers, set your exam date and target grade, and Astra assembles a topic-by-topic revision plan built around exactly what you'll be tested on.
Ask by typing, speaking or snapping a photo. The tutor explains concepts at your level, asks follow-up questions and keeps going until the idea actually clicks.
Generate guided lessons, flashcards, quizzes, true/false and smart-text exercises, plus an auto-generated podcast so every learning style is covered.
Practise with realistic oral and timed written mock exams that get graded, so you know where you stand before the real thing.

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.
