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.

Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
